I have a question about a super 77 with the gas 6 cyl in it that I just bought. It seems to have a noise in the motor when its running free as in no load. I cant really seem to hear it when moving or when I am using hydraulics. But then it returns once you stop or quit using the hydraulics. You can even seem to feel it some throughout the tractor and when you touch the crankcase. I dont seem to feel it when i touch like the generator or valve cover nearly as much so it makes me think its internal. Although it doesnt really sound like a rod noise to me, maybe a thrust issue since it stops when loaded? Any thoughts on this would really be appreciated! [Reply]   [No Email]

I"d pull the PTO Shaft and go from there. Doesn"t take that long to pull it. Four bolts underneath the power take off shaft. Then remove cover. Then remove 3 bolts in behind of the pto clutch pack then if the noise still persist I"d say it be in the engine itself. Mike [Reply]  [No Email]

Can you short out one cylinder at a time and see if the noise goes away.? [Reply]  [No Email]

Are the gears in this motor close to the mid point by the distributor? [Reply]  [No Email]
