Compression readings for a MD??

lbg57 · Feb 11, 2012

What would be an acceptable low end compression reading for a MD on the diesel side? What is the low & high end range? I can't seem to find it in the service manual. Thanks.

I've never seen an actual number for compression readings. I've always seen something along the lines of "if readings for each cylinder are within 10% of each other" then your good. If it helps at all both my 504 and my A readings are around 130-150psi... These are both gas engines so a diesel maybe more. Hope this helps.

compression for a MD was 540 lbs on a 264 engine .
the information is on Weber's tractor in the tune up
part.
