Craig, good advice, I have ordered a couple of bushings to have on hand, the thing, the delivery time up here in Canada is anywhere from 2 - 3 weeks.
Will see how the user made bushing turns out

Dave1

Jerry, I have, what I believe is a modern driving plate bushing left over from the last transmission rebuild. In that case it didn’t require replacing. I am not happy with the fit, I can push it into the housing by hand, at least for the the first 1/2 “ However, have an oversized bronze bushing that...

Dave1

Looks like I will be replacing the bushing in the driving plate, not impressed with the fit of the vendor supplied ones. Question is, how important is the diagonal oil groove to the function of lubrication? This bushing is about 1.250 inches length, wondering in 1926 if they even had an oil groove ?...

Dave1

Got it thanks

Dave1

Going to re Babbitt the fourth main soon.
When it goes time to line bore to size , I will be using my lathe, which surface on the ball do I use to indicate off ?

Dave1

What is the current Go-To timer ?
I have tried the Anderson timer, which I was not happy with .
Had great success with the TW timer, however it is no longer available.

Dave

Dave1

Is anybody making new driven gears?
I have a new low speed drum and a nice gear.
Installing new triple gears with needle bearings.
It seems a shame to use a worn driven gear.

Dave

Dave1

Anyone know the manufacturer part numbers for the front crankshaft seal and the camshaft seal. Ex SKF or National.
Simpler for me to source from a local bearing supplier rather than the T parts supplier

Dave1

Got it, thanks

Dave1

I will build up the OD of the anchor pin, then machine it to fit the hole in the bearing.

Dave1

Installing a new 280 camshaft into a 26 engine. Apparently someone had installed an earlier cam ( pre 24 style) as it has the longer front bearing,…. Not a huge issue as I can cut the bearing to the required length on my lathe. This engine engine was rebuilt recently, so I am going to try and re use...

Dave1

Thanks fellas, will try that tomorrow

Dave1

Any engine builders out there have a suggestion as how to mill a woodruff key slot key slot into a crankshaft to install the crankshaft gear? My project involves installing a Chevy crank into a T block, so the front of the crankshaft have been modified, part of the modification involves cutting a ne...

Dave1

Gotcha, not a huge job to mill the saddles out a tad.
I know…..”How many thousands are there in tad?”

Dave1

No pressured oil system, splash type

Dave1

Jerry, I like that quote! Kerry , you are correct in that the mains are not centred to the bolt holes, I referenced the camshaft when setting up the align boring machine. The thinnest Babbitt is up near the mating surface of the main right next to the bolt hole. At the bottom where the oil channel w...

Dave1

Let me explain , I have a crankshaft grinder as well an align boring machine.
The mains saddles in the block have been sized to accommodate the Chevy main journals,
I am just asking if .010” - .012” is too thin, hoping some engine builders will chime in.

Dave1

This a modification, installing a Chevrolet crankshaft int a T block

Dave1

In a perfect world, how thick should the babbitt be ? talking about main bearings
I understand that more is not better, but how thin can you go,.... without losing sleep, in my case I have measured .010 - .012"

Dave

Dave1

Kerry apparently resides in Australia, and I am in Canada

Dave1

Thanks guys, I have a plan

Dave1

This is the splash line system, no oil pump.
Looks like in the picture you provided, the lube hole is centered to the bolt holes. I take it this is the centre journal?

Dave1

I have a 26 block that I am about to align bore the mains. The Babbitt has been poured some time ago, unfortunately I do not the location of the oil hole marked. I would like to drill from the bearing side through to the hole in the upper side of the block. Does anyone have the position of the oil h...

Dave1

Thanks Kevin,
Will start welding today…..fingers crossed crossed !

Dave1

Kevin,
When are welding the boxing plates to the rod, do you secure the rod in the alignment fixture to minimize warping.

Dave

Dave1

Kevin,
The Chevy rods has a spacer plate between the connecting rod and the cap. This spacer is .125” thick.
Although when I disassembled the engine there were no shims to compensate for bearing wear.
Question, do you install a few shims when assembling these rod?

Dave

Dave1

Does any know Ben’s condition?
I send him an ignition switch back in June of this year.
Apparently he has undergone cataract surgery a month or so ago.
Tried phoning, no answer and he does not do email.

Dave

Dave1

That sounds reasonable. But I cannot imagine a circumstance where the cap would need to be filed .050”
Maybe over the course of many refits ?

Dave1

I have recently acquired the tools and machinery to pour and size babbit, I am not professing to be an expert by any means. However I have made some observations, it seems that the older engines I have disassembled which appear to have OEM Babbitt. I only “assume” these to be OEM, for example they w...

Dave1

Gotcha, thanks

Dave1

What is the recommended radius for the ends of the bearing journals when grinding. I have a coupe of cranks on hand, it seems the last fellows that ground had different ideas.

Dave

Dave1

Thanks Kevin, good advice. I have a 28 Chev engine that will be the doner for the rods. The crankshaft I will be using is from another engine and is ready to grind. It seems the guys at Chevrolet did things a bit different than Ford. The rods have a spacer about .125” thick between the rod and cap. ...

Dave1

Thanks for the info, for this purpose a length of 7.00 will do fine

Dave1

Any one know what the specs are for a T connecting rod is from centre - centre, small end to big end ?
Need to make an alignment jig for welding Chevy / T
Rods

Dave1

I realize this is a bit of a contentious topic, but I would like to put it out there just the same. Question is, whether to add Babbitt to the sides of the rear main bearing saddle on the upper (block) side. One school of thought argument against is that in order to get the Babbitt to stick you shou...

Dave1

Thanks Mark

Dave1

Mark,
Which brand do you use?

Dave1

Thanks Kerry,
This will be my first crack at pouring Babbitt, thanks for the tips

Dave1

Kerry,
Aluminum foil I will have, exhaust sealer are you referring to header wrap or gasket material?

Dave

Dave1

Thanks for the tips

Dave1

Wondering how far can you bore out the main bearing saddles, on not effect the process of pouring Babbitt?
The concern is if you expose the bolt holes the molten Babbitt will leak out

Dave1

I will be using the rear main as the thrust , rather than the centre main as the Chevy crank was designed

Dave1

I have the bearing caps made up. I had planned on having about .050 “ of Babbitt on the rear thrust surface, however it’s looking like about .150”
The final will depend on outcome of the crankshaft grind

Dave1

What is the best thickness for the Babbitt on the thrust faces on the rear main cap? Making a set of bearing caps to accommodate a Chevy crankshaft. Let’s just say that some of my calculations were wrong, and the cap is a bit undersize in the length direction. Wondering how thick the Babbitt can be ...

Dave1

Anyone recall the centre to centre distance from the camshaft to crankshaft?

Dave

Dave1

Today’s project is get the Tobin Arp line boring machine operating. With the operating instructions in hand, most of the steps are pretty self explanatory. Untill it gets to the section on securing the block to the parallels, It says to clamp to a stud at each end of the block. Move the parallels ou...

Dave1

Thinkin About ordering a set of Blockley tires for my 26 Tudor (450-21) I understand that Blockley is fairly new in the tire manufacturing business. Does anyone have an idea of how they wear? My last set (Universals) likely have 8 - 10K miles on them and they are done. Pretty disappointing Dave Eddie

Dave1

Anybody out there using their T to transport a bicycle or bicycles ? Thinking of adapting a rack for two bikes to the rear of our 26 Tudor. Not sure if utilizing the spare tire rack is the way to go, or would it be best to come off the frame. We plan on doing some touring but thought it would be nic...

Dave1

Very informative, thanks again.

Dave Eddie

Dave1

Any heating required, before or after welding ?

Dave Eddie

Dave1

Looks good Kevin, why do you remove the inner web? is it a weight issue?

Dave Eddie

Dave1

Kevin , can’t wait to see the final project

Dave1

Kevin, Interesting wondering what type of welding you are using, Mig, Tig or ?

Dave Eddie

Dave1

Personally I think I would purchase a high compression cyl head before I would modify the Chevy pistons by adding a dome to them. It may work just fine but I would likely loose sleep worrying about it.

Dave Eddie

Dave1

Kerry, The chevy pins are .850" dia. TXGOAT2, relatively simple to check for valve clearance to the combustion chamber, place a spot of putty on one intake and exhaust valve,install the head with out a head gasket, turn the engine over a couple of revolutions. Remove the head and measure the thickne...

Dave1

Anyone know the maximum amount of material that can, or has been removed from the late model cyl head? I am contemplating installing a set of 265 chev pistons into a T block to accomodate the chevy crankshaft I will be installing. It seems the chevy pistons are a pretty close match for the chevy rod...

Dave1

I have experience with this, as I had a small engine shop for a number years. Briggs & Stratton used the aluminum rod design without a bearing on most of their engines up to 28 hp. These engines single and twin cylinders are governed at 3250 rpm.It was not uncommon to see them with 400 hrs on the me...

Dave1

Yes, the reasurch I have done using the centre main is the standard, the thrust surfaces on the Chevy crankshaft are on the centre main not the rear as in the model T.
I used a combination of a taper and heat shrink to install the rear flange.

Dave1

Shannon, the thrust bearing will be the centre one, this will be part of the modifications to the T block to accept the chevy crank.

Dave

Dave1

I am in the process of installing a chevy crankshaft into a model T block. So far in this project I have modified the crankshaft flange as well as the front end of the crank. This particular engine had been rebuilt not long before I acquired it. When I opened it there were a number of issues, howeve...

Dave1

Yes, rotating T wheels is important, as mine were starting to wear I noticed the rear tire had noticeably more wear than the front. At the time I was a bit surprised at the amount of difference, until I considered that the front tires on a T have a pretty easy life, they are not even tasked with any...

Dave1

Thanks, I’ll take it that mileage will typically be from 8000 - 10,000 miles.
This helps as the car was restored when the current tires were installed.

Dave

Dave1

I hear 8000 miles. My car does not pull to one side, nor does it have any frame issues, Lately it is pretty much a daily driver.

Dave

Dave1

Wondering if there is a general consensus regarding tire wear by mileage? I have a 26 Tudor that is due for a new set of tires. These are 21” Universal brand. I do not have a speedometer so the mileage on this set of tires is a geusstimation. Anybody out there have a similar car with accurate mileag...

Dave1

Just so ya know…. Turns out for one thing the clutch disc drum was not installed far enough onto the transmission shaft. The locking bolt on the disc drum is designed to fit into the hole in the shaft,locking the disc drum into position, in this case the locking bolt was above the hole, this allowed...

Dave1

Thanks, all good advice

Dave

Dave1

I am in the beginning of an engine tare down for rebuilding on a 26. When unbuttoning,…removing the hogshead, it became apparent that the front of the ball cap had been touching the clutch spring support as both surfaces are scored. This engine has been rebuilt not many miles ago, and has some other...

Dave1

Thanks guys,
This is a new to me car that had been restored years ago but never driven, think I may wait for a hot day and force the top up, hopefully it will snap into place.

Dave1

Oops, obviously a couple of unrelated pictures, not sure how that happened !

Dave

Dave1

Dave1

[image][/image]Today was the first time putting the top up on the 26 Touring. I was able to get the top up but it doesn’t look right to me. The side brackets are hanging down below the bottom edge of the fabric. Plus the edges of the fabric seem to be loose? I’m hopping the attached pictures will ex...

Dave1

My next inquiry will be with the dept of motor vehicles, but I doubt if they have a variance for vintage vehicles, but it is worth a try

Dave1

In our neck O the woods we are required to run season rated tires from Oct 01 to April 01 these are identified by a M&S insignia on the side of the tire. The 21@ Firestone tires I am using have no such insignia. I drive my 26 Tudor most everyday providing it’s not snowing. It is time to replace the ...

Dave1

Great photos !!

Dave1

Does anyone have the part number of the seal?
Yes, that is correct the more oil in the engine the worse the oil leak at the starter is, but I want to run with the oil reservoir topped up for a number of reasons.

Dave

Dave1

I have an annoying oil leak from the starter motor drain hole on my 26 T. A search on the forum came up with a couple of suggestion, one was installing an oil seal, the other was installing an o ring on the inside of the bushing. This is the method I tried first, partly because I had the O ring on h...

Dave1

A single axle trailer should be fine, provided you adhere to the load rating of the axles and the tires. A model T at an average of 2000 lbs is not a huge amount of weight. Just think of all the single axled boat trailers on the road, Interesting that trailer tires in our neck of the woods are only ...

Dave1

A Chrysler or Desoto Airflow, ugly as hell I know, but ahead of their time non the less

Dave1

Great pictures !!

Dave1

It's time to change the low speed band material on my 26. The problem is the fellow who last replaced the bands did it while the transmission was out of the car, and apparently he installed the band's backwards, with the removable ear on the side opposite from the pedals. Does this mean the hogshead...

Dave1

Brent,

I would for one like to see how you set up a crank for grinding and which surfaces you use as a reference.

Dave

Dave1

Thanks for the Technical expertise, you are correct in that most of us do not have access to a crankshaft grinder or the ability to operate one.
But it is helpful to know how a T crankshaft "should" be ground, If nothing else.

Dave

Dave1

Wondering why you would use the flange to index off rather than the lathe centers in the crankshaft ends?
