Most likely those are 292 Cu In Ford pistons. If so, you will probably find that the rods have been cut and welded to shorten them. Not ideal in my mind, as welded rods make me nervous.

Dan McEachern

Yup- gas is probably the worst choice for a variety of reasons.

Dan McEachern

The Tractor Supply parts washer solvent/cleaner works pretty well- even here in California. Its pretty low VOC wise as it does not evaporate like mineral spirits, but mineral spirits is getting hard to obtain here. Forget "paint thinner" here in Ca- it's some ammonia/water based crap that is a waste...

Dan McEachern

Oh well- Kevin's cover is lost, so hopefully someone else has one on a broken carb or in their parts drawer. Thanks, Dan

Dan McEachern

Thanks Kevin!

WTB- Winfield Model M Float Bowl Cover. Hi All- I am in need of a float bowel cover for a Model M Winfield carburetor. Trying to get my daughter's speedster on the road and need a cover as the one we have is badly cracked. I have some Model M bits and pieces to trade or will buy outright. I'll even ...

Dan McEachern

Take the time to find an early pinion bearing housing. Why kludge it up at this point? Its just going to stand out like a sore thumb later! Two piece drive shaft housings are out there as well.

Dan McEachern

Tim- check your e-mail. Dan

Dan McEachern

What Tim and Allan said!. I have never understood why the Ford style rings are made out of mild steel and not a solid stainless ring. Eventually the mild steel oxidizes, warps and burns away. The ring rolled from strip may be "original" but it simply does not hold up well in an engine that sees more...

Dan McEachern

yes you can.

Dan McEachern

HI Don- what is your open spring pressure with and without the inner spring? Many times I find that heads are set up with way more spring pressure than needed for the RPM a T engine will be running at. Report back, but suspect that Steve might be correct. Also, checking with Mark at Chaffins to see ...

Dan McEachern

Bottom line is that simply providing a means for more fuel with out the air to go along with it does nothing to create more power. The stoichiometry has to be correct for either or both the air and/or the fuel.

Dan McEachern

Keith- bolt it on an oversize piece of plywood. Then get a big piece of carboard and roll the head and plywood up in the cardboard with the cardboard hanging over the two ends of the head by several inches. then tape the roll up, stuff the ends of the roll with folded cardboard, tape that and drop t...

Send them all back and purchase a set of rebuilt coils from one of the coil folks listed on the supplier page. If you still have your old coils, have them rebuilt- you and your car will be much happier in the long run.

Dan McEachern

Milling a stock head 1/8" will not give you any noticeable performance increase. Others may not agree. What diameter valve stems are in your engine now? are the guides worn or have they been previously reamed to an oversize? You need to provide more info on the current condition of your engine to ge...

Dan McEachern

Everyone asks why someone does not make this and that part. When I made the straight knurled early rim nuts for Larry last year (more on a favor/challenge basis for us) and I added up all my time and material, programming time etc, I tried to set a reasonable price for them and struggled because I r...

Dan McEachern

Steve- the stem has no effect on the Cover as it threads onto the rim nut, not the stem.

Dan

Dan McEachern

Norman- Kevin is making a float bowl for a model S Winfield carb. The S and SR Winfields were made after the Model M barrel valve carburetors.

Dan McEachern

early blocks did not have the oil holes in the valve galley.

Dan McEachern

M's have 3 circuits- the early barrel valves only had 2 as I recall. Here's proof- just keeping ya honest! Jeff is correct though- Winfields do make an engine run quite well.

Dan McEachern

Those are not true safety hubs as the spud should never have the ability to separate from the inner race of the bearing as shown in the picture above. Safety hubs require that he spud and the wheel/hub need to be removed from the housing as a single assembly.

Dan McEachern

As long as you never break an axle!

Dan McEachern

Yes you can move the ring gear to the other side of the housing with no modifications.

Dan McEachern

Did you contact Mark at Model T haven for an original panel?

Dan McEachern

Hi Tim- you might post your question over on Ford Barn in the Model A forum.

Dan McEachern

You might give Russ Potter a call.

Dan McEachern

Wait till they think your speedster is theirs!

Dan McEachern

Be aware that cracked drums might have good gears attached and those should not go in the scrap bin.

Dan McEachern

got a picture?

Dan McEachern

" All I have to do now is finish my Akron-Hed project and about fifty others before I can start...". Ha Ha! You have two projects that come to mind that you will NEVER be done with! Been there- doin' it.

Dan McEachern

Miller, Offy and the later Drake Offys don't have cylinder heads. The cylinders and the combustion chamber are a single casting, or castings, depending on the engine in the case of the Millers.

Dan McEachern

Just an FYI to all. I'm going to start production of the triple gear pins in the next few months. We have the steel on order for the 1st batch now. The pins will be made from a chrome-nickel alloy steel, properly heat treated and ground to size. This project is an outgrowth of making the special pin...

Dan McEachern

Regarding pan dimples- a little trick that seems to help with pan distortion- cut a slit in the side wall just under the thickness of the pan rail at the top of the dimple. I use a small cutoff wheel in a die grinder. Then dimple the side wall and weld the slit closed and grind smooth. This allows t...

Dan McEachern

Andy- I will always wonder why you didn't paint your Mercury olive drab!

Dan McEachern

It would be great to have longer wood wheel bolts for use with safety hubs. The current alternative is not ideal. Also, if you do make the nuts, cold form the threads, don't use a cut tap, the threads will be much stronger.

Dan McEachern

Nothing wrong with cast drums as John mentions, and I don't want to imply anything different- its just a different process to get to the same end point. When Herman Harder was making new drums, his were cast from ductile iron and you just had to balance them. Its unavoidable, as no casting will have...

Dan McEachern

All good points, the bottom line is if you are building a driver engine, balance the drums, triple gears and the flywheel. That goes double for a flywheel with the magnets removed. Dave N. drums are certainly nice, and because they are not machined from a casting, the are, by default better balanced...

Dan McEachern

We just finished a transmission balance job for a customer and I thought I would share what we found when balancing the low and reverse drums. I have to say that while these drums were out of balance more than most, these were original Ford drums in pretty nice condition. Most times they are not thi...

Dan McEachern

I told them 1914 and they asked me to hold. Another person came on the line and wanted to confirm that the year of my car was 2014 and I told him no, it was 1914. He argued that I told the other person 2014- he finally hung up on me. I was looking forward to renewing my warranty!

Dan McEachern

On your rear hubs, you really should add an extension on the outer end to support the outside end of the wheel center. Leaving the outside of the wheel center unsupported will eventually cause the wheel center to crack around the lug bolts due to flexing. Neglecting this detail is often the case if ...

Dan McEachern

Did you get one?

Dan McEachern

On a hard pull, you are better off using 3/8 bolts with nuts. The pins tend to allow the puller arms to spread out and bend. Just FYI.

Dan McEachern

Push thru grinders like the Van Norman and Petersen are great IF you know how to properly set one up, level the wheel, and use it. If not, you can certainly create a mess of things. I'm not fond of the belt sanders for the same reasons, but in the hands of a good operator and a machine in good shape...

Dan McEachern

Fastenal? Is that who you are thinking of?

Dan McEachern

I know what I did 40 years ago- went to the pile and got a few different coils to try and hope it ran better with those that the ones I replaced them with. Out of desperation, I would try changing the sound of them by "adjusting" the points.

Dan McEachern

Age old question- is the plug in the tail shaft? Assuming it is, you can take a piece of 3" exhaust tubing and tack weld an oil shield onto the 4th main body over the spring to keep oil off the bearing . Also get a bearing that is both shielded and sealed if possible. Is it an R24 bearing or does it...

Dan McEachern

You could possibly work out a ride with Freighter JIm if you could wait for him to get near both of you or al least close enough to meet him on the road somewhere close.

Dan McEachern

Call Brassworks.

Dan McEachern

Studs are always a step up from bolts, but depending on the firewall situation on a particular body/ firewall, and the need for the extra height to pull a head with studs in the block, it can be an issue. Removing the firewall/body in order to remove the head can be a major PITA.

Dan McEachern

Donnie- e-mail sent. Dan

Dan McEachern

That's why stock Rajo pushrods are 1/4" diameter. Same with stock Frontenac. Your friend will just need to pull the head and see what condition the block is in and then make a decision. Trashed valve seats or enlarged guide bores would require the block to be removed from the car, unless you have th...

Dan McEachern

These are exactly like the originals in every feature. Larry has even blessed them as being correct!

Dan McEachern

Thanks Larry! And of course RV for making the dies. Here is a picture of the early rim nut.

Dan McEachern

loose wheel hub bolts will make a clicking noise if you have wood wheels. Check the 6 bolts and make sure they are not loose.

Dan McEachern

Great find!

Dan McEachern

Bryan- changing the bands on that thing would be easy- just take the hood off! Thanks for posting that Tom.

Dan McEachern

Does it have the flats on it to limit rotation?

Dan McEachern

Yes, rear end is Model T.

Dan McEachern

Yes it should be a press fit- about .002" interference.

Dan McEachern

There is a version of a B Rajo where the back of the head is sloped to clear a 26/27 firewall.

Dan McEachern

I agree it needs to be checked but don't agree that using the tail shaft/drive plate is the way to go. I did not mean to imply that checking the tail shaft is the only check to do- only that runout here is indicative of conditions that can and do originate in other area of the assembly. Nothing mor...

Dan McEachern

All other issues aside, if your engine is on a stand, tip it up nose down and put an indicator on the transmission tail shaft and rotate the crankshaft. The result will tell you how deep you need to dig into things. A well built engine / transmission will have less than .005" TIR. The Tulsa club web...

Dan McEachern

Hard to tell- is the babbitt at the apex of the groove lifting up? Might just be a burr kicked up by the grooving tool on a 2nd pass- look how the groove is somewhat displaced off to the left of the arrows. Try prying on it with a box knife blade or Exacto knife. The other groove that I put the box ...

Dan McEachern

Biggest issue with a T head is the number of head bolts and the layout make it difficult to get great clamp pressure on a head gasket, but it does seem to work most of the time. I've had good luck using Copper Coat on solid copper gaskets as far as preventing water leakage. As far as torque- ya need...

Dan McEachern

yes, they hung up on me also after telling me I told the other person 2014 model year and I corrected them.

Dan McEachern

That's not something that I would do, but if you proceed, have the axles magnafluxed for cracks before you put any more $$ into them.

Dan McEachern

CDA954 is aluminum bronze and is probably overkill for anything but the most severe pin bushing application. It would help to know what the piston material is that you need these bushing for. The Ford cast iron pin bushings are probably something close to phosphor bronze.

Dan McEachern

RV- check your PMs. Dan

Dan McEachern

TTT. Still have one shaft available.

Dan McEachern

Take it apart and put all the guts in a USPS flat rate box and ship only the case and shift tower by UPS. The old "crate in a box" applies here!

Dan McEachern

Watch out Tony- those ladies are gonna pass you one of these days!!! Congrats to everyone!

Dan McEachern

Also, laminated Model A connecting rod shims work nicely for this purpose.

Dan McEachern

What Kerry said. The rings will never be able to control the oil with it that high- 3/8" above the inspection plate is almost too high.
Also, welding will shrink the metal in that area and warp the pan, so make sure the pan get checked on a jig.

Dan McEachern

Have your coils been rebuilt and properly adjusted?

Dan McEachern

Bob- thank you for posting that! I do find it curious though, as I've had 30 x 3 1/2 Buffalo wires on my touring going on 20 some odd years and probably have over 50K miles on it in that time, worn out two full sets of T drivers and have never had a tire creepage problem, and I know that two of the ...

Dan McEachern

if they are nickel, I would like to purchase them and will send an e-mail. Dan

Dan McEachern

Are the buckles and footman loops brass or nickel plated per the description?

Dan McEachern

What year is your car? It makes a big difference in what's "original".

Dan McEachern

The head gasket adds volume to the combustion chamber and needs to be accounted for in any CR calculations. A 3.875 bore overhead gasket is about 0.73 cubic inches, while a stock flathead gasket is pretty close to 1.09 cubic inches.
for conversion 1 cubic inch = 16.39cc

Dan McEachern

Ha! when did we start being concerned about "low end efficiency" with any of this?
My comments regarding port flow were directed at your earlier statement, not anything to do with resulting performance. You can't change the fact that more air = more fuel = more power.

You said:

Dan McEachern

I have flow data on a B/BB Rajo and the intake port flow curve continues to rise even after about .500 lift. Those heads will flow an insane amount. If you compare B/BB Rajo flow data to just about any other era head, most intake port flow curves flatten out at higher lifts as would be expected. I'm...

Dan McEachern

Who spotted the two Storm connecting rod boring machines in one of the pictures?

Dan McEachern

1st off, there is no one in Santa Rosa that I would let weld on that head, nuf said on that. My opinion only. Seats are bad mojo in those heads due to the thin area between the valves as you noted I think I would 1st try just grinding the seat and see where you end up- not ideal and the seat will be...

Dan McEachern

The driven gear bore per the Ford drawing is 1.651"/1.652"

Dan McEachern

If you find your brake drum shaft is worn, I make driven gears with undersize bores that allow use of slightly worn shafts.

Dan McEachern

Also, notice the edges of the drums are sharp from wear. If you are going to run Kevlar lining, the edges of the drums need to be chamfered and polished as well, in addition to no big pits or excessive roughness on the drum surfaces.

Dan McEachern

The pins are not tapered. The bore is not tapered. The book is correct in that the pins must be pushed out toward the magnet side of the flywheel. There is no counterbore in the flywheel to accommodate the slight shoulder on the end of the pin. The pin gets driven in or pressed in until the shoulder...

Dan McEachern

That looks like a reasonably terrible rebabbit job.

Dan McEachern

Suzanne- contact Moose Motors in Pengrove- they have stock of old woven lining and can reline your bands.

Dan McEachern

Call Birdhaven. Bill sold his brake business to Texas T Parts and that all got sold to Birdhaven several years ago.

Have you tried calling Best Gasket?

Bumping to the top - see my edited posting above. Thanks, Dave!

Still have a dial phone in my shop in one area. My daughters friends just stare at it.

A few additional comments on this. if you purchased pins with no end shoulder, send them back for a refund! They are simply not made correctly. On edit: I just had an interesting conversation with Dave from Chaffin's on this subject, and one of the things we discussed was the end shoulder. Chaffin's...

Dan McEachern

pretty much, except it was Land Louse virus instead of Model T virus. The little buggers are kinda cute, but not my cup of tea.
