I'm tearing down three 1929 engines to hopefully piece together enough good parts to build one or two good ones. The one I tore down today had three paper gaskets between the front plate (P/N 836475) and the block, as if somebody had tried to shim the front plate away from the block. I can't figure out why anybody would do that. Has anyone ever seen that before or do you have an idea why that would be needed?  All the Best, Chip

Perhaps seam was leaking, added more material to try to stop leak?

Yes I would think it was done to stop the timing gear cover from leaking also.

Maybe, but this is the gasket BEHIND the front plate (the one the front mounting bolt is peened into), not the gasket for the timing cover. Who would go through all the hassle of removing and nearly completely disassembling the engine (removing front pulley, camshaft, timing gear, etc for that? And there was no permatex or sealer on it and no indication that anything was warped. The entire face of the gaskets was equally compressed. I still think they were trying to shim it for some reason, but why? I'm still puzzled.
All the Best,
Chip

In my 34 shop manual it has a procedure for assembling the front plate. It states that the plate can be assembled to the block with one to three gaskets, for proper timing gear alignment. Don't know if the 29 would be different. Can go into more detail if you wish.

That's interesting. Maybe that's what was going on, but to be honest, I wouldn't think that the alignment of the two gears would be THAT critical and the gaskets are very thin -- maybe .010" or less. I sure can't think of any other explanation, though. Thanks for chiming in.
All the Best, Chip
