I bought a pretty nice old 8820 JD for wheat harvest this year - and its been a nice combine. The only thing wrong I've found was the electric header clutch switch wouldn't engage. Just to get going, I read about bolting the drive sheave to the inner sheave with two bolts so it drives all the time.
That worked fine, until it broke the two bolts off - inside the inner pulley.
Does anyone have any tips on the easiest way to get those out? Will I just need to pull the outer pulley off??
The bolts coming loose knocked the electric brush holder off the end of the shaft. With it off, I put 12 volts straight to the shaft electrical contacts and the clutch seems to engage fine, and I'm getting power to the leads there, so I guess that brush holder was the problem all along...
The only trouble is, JD will have to order it, so it will take several days, and I'm almost finished cutting, so I'd rather bolt it up again just to finish.
Thanks for any advice,
Howard
