yz 125 clutch push rod

I bought a 2006 YZ 125 for my son this spring that had very few hours on it - actually when I picked it up it looked like it came off the show room floor.  It still had warning / caution stickers on the fenders and no scratches at all.

 

The problem I ran in to today is a broken clutch push rod.  I did some searching on the internet and it seems that lots of people had this same problem back in 2005 and 2006 but I haven't found any real answers.  I'm guessing that since this bike had very few hours on it that I am having the same problem now that lots of people were having 7 years ago.

 

I changed the shift stopper lever right aways as preventitive maintenance about 4 months ago.

 

Is there a fix for this broken push rod?  It seems that some people were replacing the push rod only to have it brake again right aways. I also noticed that some people were replacing the OEM push rod with a solid steel push rod made by a company in the UK but that appears to be no longer available.  I also checked to see if the OEM part # was different on a 2013 YZ 125 thinking that maybe they cane up with a better design but it is the same part #.  However that really doesn't help me because it doesn't tell me if the 2013 uses the same push rod as the 2006 did or if there has been a change up and the part # that I am looking at for the 2006 is already an updated part.

 

Does anyone have any expertise with this problem? 

Was the bearing still on the shift stop lever?

Only time I broke pushrods was when the shift stop lever bearing came off and it toke out the bearings holding the shaft that the push rod goes through.

No it wasn't still on the stopper - it was worn right off.  I looked through the case as good as I could at the time to try and find pieces of it but they were nowhere to be found.  I even used a scope camera to see to the other side but nothing.  I realize that the pieces may have been in there somewhere and I just couldn't see them but I figured maybe the pieces came out when the previous owner changed the oil and he didn't know what they were and I kind of passed it off as maybe that's why he sold the bike.  

 

I'm kind of hoping that no bearings are ruined inside.  I wiggle the shaft in which the push rod goes into but there is no play in it.  There is one race left this season and I was kind of hoping to just install the push rod and let the kid race it but I am a little scared that there might be something else wrong in there.

Not going to happen and is dangerous to ride that way.

If it snap the push rod the bearing is done if it goes completely your case will be ruined.

It cost me $110 for all the bearings in the transmission so not that expensive.

Shucks!  I was hoping you wouldn't say that but you're right that is not much money just the down time is the main concern.  I guess maybe he will have to ride a 250 this weekend rather than take the chance.

 

thanks!!

HA !!    You were absolutely right!!   I really didn't want to split the cases and the whole time I was taking the motor out of the bike and stripping it down I almost talked myself out of doing it - just because the bike had been working so good and the shaft felt solid as I tried to wiggle it from the clutch side so I figured the far side bearing must still be good.  NEVERTHELESS I went ahead and split the cases and sure enough that bearing on the left side crankcase, where the shaft that houses the push rod runs inside of, well that bearing was completely destroyed - haven't seen a bearing that screwed up in a long time.  I've got all new bearings on order and hopefully my son can be riding by the weekend again.  Looks like a good cleaning is in order as well.  Man that bearing was mashed up!!!!

 

Thanks - had I not joined this forum to ask this question I am certain I would have installed the new push rod and put the kid back on the bike.

Where were you racing this weekend?
