Re: Magnet leveling

You guys are going about leveling the hard way. As Dan McEachern says and it's the way we do it quick and easy.
Any local machine shop can resurface the magnets as we have .

Re: Engine Rebuild Cost Estimate

Hey everyone, Trying to get a rough price estimate on an engine rebuild. My 1923 Ford Model T runabout had low compression (but still ran) and needed all new pistons, piston rings, valves, guides, new camshaft, new timing gear, "re-babbited", new transmission bands, etc (basically a full-engine reb...

Re: Rocker Arms Unlimited, Redding, CA

We've always used them for our engines rocker arm rebuilding.
I always speak with "Gary" and never have had problems.

I'm surprised that anyone would of had problems with them unless it was from a long time ago?

Re: Transmission Disaster avoided

I know it could get noisy with a drum change but I will hope for the best. I have at 1st glance what I think is a nice looking set of drums from a later model transmission can anyone tell me for shore I believe they are the same as the earlier low and reverse drums Or are there differences. The Low...

Re: Cracks between intake and exhaust

Those need to be repaired .
We don't see this crack to often but when we do it has to be repaired.
We use metal stitching and it is a seamless stress free repair.
With hardened valve seats installed it will never crack again in that area.

Re: Mag Particle Results - 1911 Crankshaft

Was the crankshaft washed and all grease and debris removed before crack inspection?
You won't get a true reading if there is oil or dirt on the crank.

From what I see those are a result of the forging process as long as they are away from the radius of the crank.

Re: Transmission autopsy: Bad driving?

Even when I asked if the flywheel is toast I was pretty sure of the answer. Fortunately I have a few others, so finding a replacement should not be a problem. I also have several low drums, so it should also be no trouble finding a better gear. I believe this hogshead has a new low pedal notch and ...

Re: Transmission autopsy: Bad driving?

Mr.Jelf the flywheel is toast. It's not uncommon to see bushings fused to the pins but another to see the pin moving! I stated earlier that all parts should be crack checked and flywheel is one of those parts. There is one triple gear pin hole that lines up with two other holes on the flywheel and t...

Re: Transmission autopsy: Bad driving?

To all concerned. Since majority of engine parts are reaching the 100 year old mark. Notwithstanding I would recommend any part in an engine to be "Magnafluxed" Crack inspected. As Mr.Jelf found out the hard way that, I would recommend it for any and all moving parts in a engine. That's why we ended...

Re: Freeze Crack Repair

I found some water in my lifter galley, and an old repair in the water jacket between 2 & 3. The repair is oil-colored and lifting around the edges. I can't tell if its JB Weld or Marine Tex. One of the freeze plugs is covered in white epoxy; pretty sure that's Marine tex. it will be impossible to ...

Re: Loose rivets in brakedrum

One more thing, Since no one else has mentioned this. Since the brake drum is loose on the hub It would be wise to get the Brake drum crack inspected. Most often we see engines with good drums only to fail the crack inspection as the rivet holes are cracked around the rivets. Makes no sense to reriv...

Re: Loose rivets in brakedrum

Can I save this by trying to heat the rivets individually (somehow) and hammer them so when they cool it will be tight again? Or what does one do? (Apart from finding another) It is better to remove them and purchase replacements and then start over. The rivets along with the holes will be worn and ...

Re: Triple gear weight

Trying to balance it the way you are is a bit difficult.
If you have someone that can spin balance the flywheel you'll be in a lot better place.
Then you can contemplate machining weight of the triple gears.

We typically charge $80.00 . In order for the magnaflux to work properly the block has to be perfectly clean,no paint,oil or dirt.

Re: High rpm vibration

What you are explaining is typical of old engines not being balanced. We're so used to modern cars and forget what original cars are like. It can be corrected by balancing the internal engine parts. Rods,pistons crank, flywheel. Most often when the magnets come off others of random weights are re in...
