Hello,
I am having problems with a fairly high hour (4800hrs) LS140 skid loader w/ N843 engine. Engine start and runs, not much smoke of any kind but LOUD knocking noise. Hard to tell if it's top or bottom end of motor. Compression testing on 1 to 3 cylinders was 475, 250 and 325 - so 2 and 3 are low to spec. My next steps:
1) Confirm valve setup / clearance
2) Check timing
3) Pull head - should I do something else prior to this?
I have the complete shop manual - if I am going down a path of a complete rebuild, any other advice?
Anything else that I should be concerned about with this loader and given it's hours? Hydro seems OK but I very reluctant to run it much. I will replace all filters / fluids / lube prior to use.
Thanks,
Fred
