I have a 2000 trailblazer that was feeling like a gear had begun to go bad in the gearbox, and opened it up to find a chain (like a cars cam chain) loose and with no appearent way to adjust it. It looks very heavy duty and must be stretched (hard to believe a trailblazer could do this as I have a hi-perf. 400 & 3 500 scramblers with no problem like this). Anyone out there go through this before? Thank you in advance.

 

This is a common problem. Just replace the chain and fill the trans with good synthetic motor oil such as Castrol Syntec 5w50 and it will not give you any more trouble.

 

It is a comon thing for the chain to need replacing.But I would stay with chaincase lube and not motor oil.

 

The chaincase lube is why it is worn out.

Use good synthetic motor oil.

 

If the lube is the problem why have I only replaced 2 chains inthe last 10 yrs of riding Polaris?I still think the manufacturer knows what is best for their machines. And the 2 chains I replaced were first on a 425 Magnum 4x4 that was mudded and abused and the other one was on a 250 Trailblazer that my son was trying to fly with and landind it hard.

 

Gotta give FTW my vote on this one too. Change the lube at least once a year...more often if you do a lot of deep water riding. There's lot's of power routed through that bugger....she's gonna stretch.


Is it just me, or is the sypware thing getting out of hand? [img]i/expressions/face-icon-small-smile.gif[/img]

 

The chains last longer with good synthetic motor oil in the trans.
