Compression

[Pete in MD]

Anyone know what the compression was on a TC-MM engine when it was new?
The engine is a model HEB, 605 cubic inch, 6 cylinder, stationary engine, built in 1946.

I think it is 80-100 psi

It will depend on what heads are on the engine.


Here is a link that may help. Look at the lower table for the earlier heads.

SWMolines,

Thanks for the chart. I checked the head on our MM today and got my question answered.

Thanks again,
Pete
