Re: what`s this on my timing cover?
i had one like that . It was used to tighten the tension on the cam spring!

Was this a Ford thing or a backyard fix?

Probably a farmer fix for an industrial engine, such as used on the old combines.

Aftermarket, but a keeper. You'll gain some steadiness at low idle if you employ that. It can be used to keep enough tension on the timing gear to stop the helical walk between the cam and crank pulley.

Re: what`s this on my timing cover?
several engine builders use that trick now, with a torrington bearing on the camshaft face. Jay Steele used to use it, it was one of the tell tale signs of his engine.

Re: what`s this on my timing cover?
Tim,
The direction of the helix cut(left or right) denotes which way it " loads " the cam shaft. The Model A will load it back, the 32-48 Ford V/8 is also the same, the 49-53 has an opposite helix and loads to the front, BUT has a thrust button to stop the cam from screwing it self out the front cover. Even when doing a 49-53 I use a earlier gear set, works better. Jay Steele, of Taylor Engines, is a sharp engine builder. Dudley |

Re: what`s this on my timing cover?
Not an "A" guy but since the bolt is in a cast boss it would be original. Hercules and others used similar to set end play in cam and accesssory drives.

Re: what`s this on my timing cover?
Au contraire! That cover with the rib under the boss looks EXACTLY like part #A-6019-A, used 1928 and on AA's that had engines bolted directly to the front frame cross-member. All front covers had a blind boss for the thrust plunger and spring. This one has simply been drilled/tapped at a later time for a bolt to limit plunger travel. The boss was there before the bolt was added. Anybody have a pix of A-6019-A ?

Yep, That's why you use it. No matter what direction the cam moves you want to retain that setting and take any advance/retard play out of it. Tim |

Jay Steele was indeed a good builder. He passed a few years ago.

Jay Steele...WAS one of the best! May he rest in peace! BTW..about a year/two ago an engine built by Jay was sold on ebay(up around Sacramento delta area). As a testimony to Jays' rep and work....it sold for 10K or so. Winfield equipped, if I remember correctly, and NEVER even run! Probably one of the guys here have it,eh?
