Hi All
On my last ride i noticed a high frequency driveline vibration through the pegs at around 4400 revs,all gears.
I pulled the swingarm to check the Uni,s and carrier bearing.
The carrier bearing seemed fine but the Uni,s fell out of the bearing.
Both bearing journals were 0.2(8 thow) undersize.
A quick glance at the bevel gears showed no signs of doom.
Stuck it back together and bingo(so i thought) the vibration dissapeared at 4400 revs but reappeared at 2400 revs,all gears?Head scratching.
Pulled the bevel box off again,washed the gears and found this.
Pitting around the top edge of the crown teeth and bottom concave side of the pinion teeth.
All bearings seem fine.No perceptable movement in the pinion bearings but a slight rattle when shaken?
These gears and all bearings were replaced 60,000 km,s ago.
Good oil with Moly used.
Do i need new gears already? I think i already know the answer.
Could a slight vibration,looseness off the uni diametre to carrier bearing cause this?
Has anybody else chewed through gears with this amount of k,s.
The first set only lasted 97,000 km.
Is this just been badly set up.
Please advise.
