Hey guys bought a 1948 Farmall C could some one tell me what compression be Also should I have a pressure rad cap non pressure since there's no water pump also don't have a manual is there some site I can down load Thanks a lot guys
 
You are looking for a close number like 120-125- 122-85. The 85 would mean trouble. A leak down test will tell you more and where the trouble is.
 
Pressure cap 7.5 psi max. A distillate tractor will be in the 100psi range Maybe even 90psi. A gasoline engine will be 120ish. Jim
