Ouch!! What was going on at the time?
Usually the clutch will slip before it comes to that.
Suspect FOD or one tooth let go, jamed in between until they were all sheared off.
Doubt you can find new gears, especially the pinion but you never know. I think I'd see about rounding up another used unit.
That pinion seems to be limited to sr. # 8D501-8D14685 on D6's only.
I had just started this thing up, and lifted the blade up - all the way up...... I heard the typical BANG, and then I heard other noises..... Was this a common failure back in the day? I had also figured that the clutch should just slip - I had rebuilt the clutch several years ago, and haven't adjusted it for at least 50 hours..... I reread the last post..... what is FOD? This thing was full of oil.

Foreign Object Damage.

Hi Team,
running the blocks hard together will cause "impact damage" to the system, especially if the unit has not been used for a period of time as the plates tend to rust and tend to not slip as easily until repolished from use.
If the clutch does not slip or the rope break ( especially if an oversize--over specified--- rope is used) then the teeth break---Operator Error.
Sorry.
Cheers,
Eddie B.
In my process of trying to find out what was wrong, I had taken the whole unit apart on the front side. I had looked at the sleeve, to make sure that it didn't turn, as when it does it will loosen the clutch - not sure which serial number, but they changed the direction of the threads - I had it happen a couple times when the clamp wasn't tight enough it would loosen itself up. I had just used this thing about a week prior, so the discs were not rusty at all. It sorta sounds to me like this is a weakening of the teeth issue like edb mentioned...... has to be weak teeth, couldn't be operator error 😆

"I also joined a year ago. had been on here a couple of times as a non-member and found the info very helpful so I got a one year subscription (not very expensive at all) to try it out. I really like all the resources on here so I just got a three year. I think its a very small price for what you can get out of this site."
