Engine won't hold a load.
Model G148B
Serial# 2651351
I have ordered a new set of springs for the governor but I don't think this will solve it. Is anyone familiar with this governor setup?
ok it wont let me post a link to the case schematic
Above part #4 in the link above there appears to be a fill hole (sort of a set screw that comes out to possibly fill with oil?) but I removed mine and there wasn't any fluid/oil in there. I also ordered the ball bearing (part #18) but to get that I think I have to take off the timing cover - which is currently holding my project up.
One of the other 480ck threads in here was someone trying to remove the hydraulic pump which is what I also need to do to access the governor assembly. Removing the cover doesn't sound easy or fun.
I thought I read somewhere else that there is a piece of plastic in this gov assembly that might have cracked. I put a scope in there and didn't see any plastic or bits but who knows.
When I purchased the tractor it ran ok but I replaced valves, had carb rebuilt, generator, etc. and now it just wont hold a load. Previous owner had a length of rope attached to the gov control arm (part# 43) that I never used but makes me wonder.
Any thoughts are appreciated.
I also have the service manual for this machine if anyone is interested. $300 from Case
