I have 35k km on my TE610. Pulled the piston last night to put on fresh rings (it started to burn oil pretty bad at the end of last season). Check out the play of the big-end bearing on my connecting rod: View: http://www.youtube.com/watch?v=kxwAkUx4Lk8 Is this pretty much done? I was hoping to not have to split the cases, but if that play is excessive than I may as well do it now. Thanks.
I think there are measurement specifications in the shop manual for use to determine if it is worn beyond specified tolerance levels and requiring replacement.
The rod is supposed to have side to side play, it is the up and down play that is crucial. Does it have any ? Fast one is correct the service manual will give you specs for replacement. I think I might do it while in there if your bike has 35K miles.
There is no discernible radial play on the bearing, only axial. I'll dig up the specs and check it. thanks.
For the 2006 the specs are: Radial Clearance: Std: .26-.36 mm (0.00102 - 0.00141 in.) Limit: 0.080 mm (0.00315 in.) Axial Clearance: Std: 0.50 - 0.70 mm (0.0197 - 0.0275 in.) Limit: 0.080 mm (0.00315 in.)
