Hello. I am new to this site. I haven't had a quad in 10 years until I bought a used 2003 trailblazer the other day. The chain was really loose. I adjusted it as directed in the manual but it still barely rubs on the housing at the top. Is this normal?
Also, the footbrake has air in line...how do I bleed the air?

 

Judge the chain slop by the play specified in the manual, it sounds normal to me.

Follow the line from the small brake "master cylinder" near the foot brake to the correct bleeder valve on the caliper (there is two) and bleed similar to a car. Make sure its full and keep filling throughout process, it dont hold much.

Oh ya, welcome to the site and a chain tensioner may be in order. Well worth the $50 in maintainence alone.
Really a bargin if you consider it saves your trans case (if chain was to break).

Thanks for the advice guys. Excuse my ignorance, but what is a chain tensioner and how does it work? Also, the chain itself is in much need of lubrication...the manual says that I must use o-ring chain lube or SAE 80/90. Do I really need to use what they say? I was thinking of using some used Amsoil synthetic motor oil that I drained from my truck. Thanks in advance.

 

Hello 4Day. Congrats on getting a Trailblazer. You got a great year for the color. My chain sometimes rubs slightly on the plastic runner on top of the swing arm. However, when you are riding, the chain is in tension on the top and should rarely touch. As far as the chain tensioner. That quad has a concentric chain system which means that the chain does not go tight and loose as the suspension deflects. The result is that you should not need a chain tensioner. Some of the older quads had a non-concentric that could benifit from a chain tensioner. As far as lubrication... LOL, everyone has his own opinion...
I hope this helps you [img]i/expressions/face-icon-small-smile.gif[/img]

Whatever type of lube you decide on for your chain, make sure it is o-ring friendly. Some lubes will dry out the rubber o-ring and eventually you'll have a chain failure.
