Re: 8ba rod bearing problem

Most bearing books have a maximum, and minimum for any given crank. On say a 2" crank, the actual minimum size should be .002 thousandths, and plus, one more .000-50 for a maximum.

If you set a...

Re: 8ba rod bearing problem

The best one was built by Sunnen, Model KN, look on E-Bay. It was made to be used just for Rods mostly when just one pin went bad. You jacked the car up, pulled the pan, put an electric motor and...

Re: 8ba rod bearing problem

Using a so called good enough crank, could mean it can very in a few tenths in size. Mic closely the pins that turn good, compared to the one that doesn't. As previously stated, check Radius, a .001...

Re: Rear main cap question

A half plugged cap hole, with babbitt, pipe screwed in to far, ect., will take 175 pounds, air pressure very nicely. Pull the soft plug!

Re: Peining Rear Mains

Our thrust is also is about .150-00 thousandths to much babbitt on either end, that is needed.

Re: Peining Rear Mains

Nothing between the punch, and the Babbitt.

Use a 45 degree angle, away from the bearing.

The punch for the air drill, is 1/2 inch diameter, round, a smooth, rounded end.

40 pounds pressure,...

Re: Peining Hammer

Other makes of cars, used inserts, and did not need peening, as most, not all, were Tinned.

The peening hammer was Wilsons, alone.

The hammers shown, are all different, because the engines are...

Re: Holes drilled in dipper tray

They serve no valid purpose.

The holes in the dipper tray, cuts back considerably, the oil available to continually feed the dipper tray. Bad idea.

I think that it was one time, a write-in...

Re: Rear main leak to clutch

I Agree, Mr Patrick, and I also have never seen oil on Flywheel, or pressure Plate.

The ones I have, ( Not Model A ) , always slipped, rather then chatter.

Re: Peining Rear Mains

The only time you need thrust support, is if you use a babbitt tool like Wilsons, using a Hammer to hit the tool with. That process, is very ineffective. Ford used the babbitt hammer, but it was run...

Re: flywheel housing shims? late production diamond block.

1. The chatter may, or may not come later.

2. No shellac for shims. The shellac is for the gasket, and the 4 flywheel bolts, as the threads go into the crankcase, they would leak oil into the...

Re: flywheel housing shims? late production diamond block.

Ok, again, you have to adjust 9 & 3, first. More then likely you will have a different thickness of shims under each bolt. What you are doing is twisting the housing casting, to get the same reading,...

Re: flywheel housing shims? late production diamond block.

9:00, and 3:00 should read alike.

12:00 and 6:00 should read a like.

All 4 points have to be a like.

This is all accomplished, with shims on the two top bolt holes.

Set 9 & 3 first, and...

Re: babbit tolerance? .000?

To pour mains in a block, and we do only 1 main at a time, that is so you have the time to give the bearing the attention that each one needs. If you do 3 at once, by the time you get to the last...

Re: babbit tolerance? .000?

With out the right kinds of grooves, you have bearing failure.

The biggest cause of flange breakage, is that the Babbitt wasn't peened,, or lack of knowledge how to do it right.

Many shops...
