Re: head stud removal

Add the crayon trick noted above to welding the nut to the broken stud. When the nut and stud cools, it sucks the parafin from the crayon into the threads and helps a lot.

Re: Rajo BB head

The intake valves have not been enlarged in this head- all B/BB/R heads used the same size intake and exhaust valves as what is shown in the pictures here. The head looks to be in great shape. . ...

Re: O/T What material would you use for new axle shafts?

Brent- use 4140HT, not annealed. 4140HT is 28-32Rc and is easily machined at this hardness. The ductility will still be sufficient at this hardness. You could use annealed 4140 and then have it...

Re: Nylock self locking nuts on main bearing bolts?

Pretty sure that nylocks loose a lot of their locking ability at the temperature an engine runs at. There are all metal lock nuts that are rated for use at higher temperature. Split lock washers on...

Re: Timing gears use.

Straight cut cam/crank gears will remove most all of the thrust loading on the cam. There will still be some thrust due to the oil pump drive- not so much from the distributor unless you re running...

Re: Main Bearing Bolts, Nuts, Washers

Also be aware that a pressure engine WILL pump oil up the bolts from the mains, so they need to be sealed where they exit the block.

Re: Is My Cam Going Flat?

Jim- I don't understand your statement about the base circle not being concentric? I would think if that's the case, the cam grinder got in a rush on his finish grind . . . . .

Re: Flywheel Housing Alignment

Another reason you can't shim between the 4 mounting holes is that the rear cam bearing seal relies on those two surfaces being in contact. Shims on the cam side for sure would compromise that seal....

Re: When going for SCAT crank should you lighten flywheel? If so, how much?

Making a statement to remove x number of pounds from a flywheel can have mixed resuts, because what you should be concerned with is changing the moment of inertia of the flywheel. Taking the weight...

Re: Rear Main Question ??

I like the steel cap because I can tin it rather than use just anchor holes to retain the babbit. I think it makes for a better babbit job.

Re: Riley Head water pump question

Original Riley heads located the water pump in pretty much the same location. Not too sure about the Yapp heads, but they should be the same.

Re: Advise for installing camshaft timing gear

There is absolutely no reason to torque the cam nut to 100 ft-lbs or even 75 ft-lbs. Where this cam from, I have no idea, but if it is in Bratton's catalog, I wish they would fix it. The advise...

Re: oil pump/dist..cam drive gear ?

The drive gear sits below the sleeved portion of the housing so it gets plenty of oil. On a B block the cam bearings are oiled from the oil galley, which in this case is under full pressure, so no...
