Re: Main and Rod Shim Sequence ???

The crank would be out of alignment at the bearings, the worst, at rest, and when running, the centrifugal force of the flywheel, tries to put the shaft back into a straight line, it has to force...

Re: Main and Rod Shim Sequence ???

I like the bearings [ rods and mains] at .0015" [ no more than .002"] with each side of the shim pack equal thickness.[/QUOTE]


Me too.

Re: Main and Rod Shim Sequence ???

What the reference is to, the middle main, as most know, the hanging weight of the flywheel, causes the the crank to bowed, center bearing up, and rear bearing down.

In a center bearing, you can...

Valcan connecting rod lathe

Excellent condition, rebuilt when I got it. Replaced all the Ball Bearings, didn't need it, but we did.

It will do any rod, and also wrist pin bushings.

Same machine as a Storm-Valcan, before...

Re: adjustable lifters

You done what is normal here.

We don't adjust with springs on.

Pull the lifter up, put on the wrench to the lifter body, push in to hold the lifter up, take the other wrench for the nut, and...

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...
