Posted November 15, 201311 yr The front wheel and forks are off..triple trees still on. Thought I would check them and notice there is a sort of click into forward, left and right positions. Is this normal?..would think things should be smooth throughout the turning radius. Are the bearings shot?
November 15, 201311 yr Moderator Sounds like they are shot. They should be smooth all the way from left to right. No noise, bar the suck of thick grease.
November 17, 201311 yr Author Found the problem..one ball bearing missing off the top end. Manual indicates 22 but i count 21. Question is..how did it escape? Uploaded with ImageShack.com
November 17, 201311 yr Author After 30 years isn`t this what you would expect to see? I`ll clean it up, replace the missing bearing and repack it.
November 17, 201311 yr Moderator After 30 years isn`t this what you would expect to see? I`ll clean it up, replace the missing bearing and repack it. well yes it is, but if there are indents on the races then It's time for something new
November 19, 201311 yr They look knackered to me , and over time you will find the balls will have flat spots and the chrome de-laminates on the races.
November 21, 201311 yr Author After a cleanup they look pretty ok to me. Can get the missing ball from the dealership.
November 21, 201311 yr Author Not to worry..actually had enough of the rat race..just want to restore these old bikes now...but have to watch the moolah with them.
December 4, 201311 yr Author Ok I`m confused..the manual indicates 22 balls on the top yoke but with 22 in it looks like one still missing. I`m sure it needs another one..can it be an error in the manual?
December 5, 201311 yr Author Hello..anybody reading this?. This is holding me up. Getting no replies so going to stick another bearing in there and see how it is.
December 5, 201311 yr Author doesnt make sense..the bottom ball bearings pack nice and tight together..why would the top have a gap?
December 5, 201311 yr Moderator Our DT's have 19 off 1/4 bearings in the bottom and 22 off 3/16 bearings in the top, the XT250G the same isnt it? http://www.cmsnl.com/yamaha-xt250g-dual-purpose-1980_model8766/partslist/
December 5, 201311 yr I've read that because the loose balls don't have a cage to keep them separated there's a little bit of a gap. Some gaps are big enough for one ball and others about half that size. As long as you have the correct number of balls I think you should be okay. ??
December 6, 201311 yr Author I`ve ordered another ball (they`re only ZAR2,00) and if it goes in nicely I`ll leave it there. The action when turning is not smooth so will check it with 23 balls in.
