Pulled the diamond drive apart and...

[Catman10]

Well I pulled the ol diamond drive out of my 07 M1000 as I do every year and took everyting apart to inspect it closely and found the small bearing at the end of the lower gear shaft (the inner one) to be shot because the seal went to crap and some fine filings or whatever got in there and it aint spinning so smooth. There is also a c clip that I am going to try to replace with a bit of a beefier one while I am at it. I just want you guys to know that you need to at least change your oil once a year for warranty, my Cat dealer told me so, hope this helps.

I've replaced all DD bearings once, and did the brake side bearings this fall. They were rusted to chit. Based on my experience, it would almost seem prudent to replace the seals and bearings once a year. My DD is on 06 model that used the 3oz of oil. Worth changing several times a season. This year I am running the Amsoil synthetic which is supposed to quiet the DD bearing somewhat and offer better all around lube. Time will tell.

Just for interest sake I went to a reputable bearing shop to see if they had better quality replacements. Not without being at a huge cost!! Kits that BD Extreme offer are actually pretty good as it turns out, and at a decent price.

I have recently bought an 08 M1000 and will be taking the reverse drive out of the machine before it's even ridden. I don't know the state of repair for the drive that you have, but if you're interested I will have the new take off for sale. $500
