I welded the square piece of metal on my teeth also, and haven't lost one since.

Either that or just go buy the teeth from JD and see if that fixes it Someone may have run the machine with the teeth off for awhile and wore them down causing them not to fit correctly. The only way I fixed it was cut all the "boots" off that being the part the tooth pins to and weld new ones on.

Posted 10:46 (#3962546 - in reply to #3962532) Subject: RE: Keeping teeth on excavator bucket Proper fit will put load directly from the tooth to the bucket 'post' and not transfer the load thru the fastener. Unless the bucket is worn enough that now tooth will fit tight. Posted 10:38 (#3962532 - in reply to #3962385) Subject: RE: Keeping teeth on excavator bucket Tried welding the teeth to the bucket, tried different retainers - what works for me has been welding a square of steel plate over the retainer clip - on both sides of the tooth - this keeps it where it belongs and it is a fairly simple job to grind the plate off when it is time for new teeth. The salesman said if we ever ran the bucket in water we might lose teeth with this retainer design, thought he was joking but he wasn't. I have had similar problems with the teeth on my 790 Deere.

I run an excavator at work and have lost one tooth in 7 years. Posted 10:21 (#3962505 - in reply to #3962385) Subject: RE: Keeping teeth on excavator bucketĪre the pins vertical or horizontal? I like horizontal as they don't come out when you dig. I will say that the OEM teeth we've used on our 120 stayed put so far. Posted 10:08 (#3962487 - in reply to #3962385) Subject: RE: Keeping teeth on excavator bucket I have not tried OEM teeth, maybe that is the answer? Any help greatly appreciated. It's a pretty good struggle to get the clip in but once in they are slightly loose. Have not tried any type of bolt either.īoth surfaces are completely clean before installing new tooth so the fit is as tight as possible. Have not tried solid welding them on all the way around, kinda reluctant to do that but getting closer to that move every day. We have tried welding the top and bottom when new clips are installed with little to no luck either, it just snaps the weld since they don't fit completely tight. Could this be my issue, they do not fit as perfect to the cast boot as I would like but are much, much cheaper than the OEM teeth. Have landed on the John Deere OEM clip for now but they don't make it long either. We have tried every clip under the sun from the rubber expansion wedge to the multiple eagle beak type clips.
