Farmall MD compression PSI ???

lbg57 · Sep 27, 2011

Would anyone know the compression PSI on the Diesel Side on a Farmall MD? What is an acceptable reading on the low side? What is a good high side? I can find the compression ratio, 14.2 to 1, but not a compression PSI reading in the service manual. Thanks.

How do you check compression on diesel side?

You can check with a diesel compression tester. I bought one on
ebay but have not used it. I am assuming it goes in the injector
bore.
