THE CALM ONE!!!!
Ok.
Many of you have probably read of my bucket truck trouble the last week and a half or so here. My rotation pinion gear (the small one that drives the rotation of the booms at the house) broke two gears off under no severe abuse or anything. It's been cold here but nothing ridiculous I was rotating not even with full juice and it jammed up I came right down and it had already broke the two gears off.
So I replaced the entire gear box because it wasn't that much more than just replacing the gear/shaft and I was somewhat suspect of the internals of the old gearbox thinking they could have had something to do with the failure if a bearing or something had worn to much and developed play. Also I hadn't been maintaining the gear lube properly, after careful study of the manual I had been lubing the rotation bearing but not the rotation gear, that I'm thinking was the main culprit in this failure. An expensive lesson to learn in fully understanding all the maintenance that is nescessary on a piece of equipment.
Anywho I got the new gearbox and have it installed. Somehow in the sending of a $3800(by the time it arrived on my door) gearbox no one thought to include any of the special plasti-gage shims that I can't seem to source anywhere around here locally. I have been using plasti-gage for measuring mainbearing journals to help me in my adjustment/set-up of this new gear.
My question is does anyone here have any experience with setting up the 'gear lash' on a rotation pinion for a boom? Any suggestions, tricks, or comments?
I have it set-up to where I finger is the proper tolerances but I've never done this before and can't find/don't know anyone at all local who has any experience with this. My worse nightmare is to have this thing go crunch again. Obviously I'll be monitoring it like crazy the 1st while and on a regular basis afterwards but just thought I'd check with the House to see if anyone has any info.
Thanks,
Justin
