I am into this project and I thought I would start a little entry on it.
I have a Ford LGT 165 Closed Sided Tractor made by Jacobsen.
I have discovered two symptoms of problems so far:
White Smoke when running and Hydraulic lift not responsive or very slow and weak.
Actions done so far:
Changed Hydraulic filter and Hydraulic Fluid. No improvement.
Next step will be to check the pressure relief valve. Then if needed take the hydraulic lines, lift cylinder and control valve down and clean and inspect them.
Regarding the white smoke:
I checked valve clearance, and did a leak down test and had 0 pressure. I disassembled Cylinder Head and found that oil was leaking from the cylinder head but the head gasket was not blown.
I cleaned everything off, cleaned the threads for the head bolts with a tap, reinstalled cylinder head, head gasket, and re-torqued head bolts to spec.
I ran the engine and it started right up with less smoke than before but still some smoke.
Repeated Leakdown Test, and found that I now had only 50% pressure and oil began pushing out of the valve cover area. I think this indicates bad rings, as the air was able to push past the piston rings and pressurizes the crankcase forcing oil up the valve stems and out the breather.
My projected plan of attack is to replace the piston rings and measure all internal components while the engine is apart. Replace anything that is necessary but hopefully just rings are needed. When I had the head off, the valve face, and seats appeared to be in good condition is were the cylinder walls. Nothing blatantly obvious but the measurements won't lie.
That's where I am now. I am hoping to have this running by time snow starts falling so I can try plowing with it!
How am I doing so far?
Tips, insights, experience, stories welcome!
