450B left steering problems

Post by Johnstas » Tue Jul 26, 2011 5:04 pm

Wondering if someone know what is going wrong when I pull on the left stick and nothing happens. Does this mean the steering clutches need replacing ? It looks like the brake band is okay. Any advice would be appreciated.

It may just mean that steering lever is way out of adjustment, especially if you are getting nothing after fully pulling the lever (i.e. when the brake band should be applied). I would go through the adjustment procedure in the manual first and see if it makes a difference.

steering problem

I adjusted the left clutch back the way that it was. Now I get right steering, but the left is still very little. I do have bushing wear in the sticks.
should I just try to adjust a little bit of clutch at a time ?

do you have power to both tracks? if so than you dont have a bad clutch. A bad brake or adj.or linkage is where to look
