Now to find the right parts…. anyone know where I can get a manual with part numbers ASAP (already emailed Yuchai twice, and called Keno)… Looks like I am going to need a whole drive shaft assembly, seals, bushings, bearings, etc… Looked at Circle G website, and will price through Northern Tools… any other suggestions on places to find these parts??? not looking forward to what its going to cost… appreciate all input.
Good call Bob!Finally got the track off and final drive partially apart…. broken drive shaft.
… finally got around to getting the dozer on blocks and testing the drive train. Sure enough, once put into drive, right side moves normally but the left doesn't move, and only occasionally “twitches” like it is trying to go forward…. good news is this ruled out the brake issue, bad news, looks like I have to tear into the final drive to see what's broken, thanks for your help bob, may be calling on you again once I identify whats going on….
Thanks Bob… you've got me thinking about that left drive train… I think you might be on to something… and that may have more to do with the initial left track being thrown… unfortunately im out of town for several days, will check when I get back and post again, thanks for your help.
nope… when the right pedal is depressed, the left pedal remains in its position. The pictures are small, the material that came out of both drain plugs, I assume is just dust/material from the brake bands.
Am I correct from reading previous posts, that there is no easy way to get to and inspect the brake bands?
…. checked brake pedal cross shaft, found lots of dirt packed up underneath the shaft, cleaned it out… no change. Located the plugs and removed, picture shows what I hope were the right plug(s) and what came out…
… look right?I fired it up again, pulled off the blocks, and no change. The right brake completely stops the dozer, both tracks, forward and reverse. The left pedal feels like it is trying to “grab”, but does not stop either track… could this not be a brake issue at all and possibly a clutch issue? I”ve got a call into Keno for help but haven't heard back from anyone yet … frustrating.
Thanks Bob… will check the steering compartment drain plugs and see what comes out. And yes, dozer comes to a complete and immediate stop when right brake is applied… which I thought weird as it is my understanding that the brakes operate independently of each other… will check drain plug and brake pedal cross shafts.
Bob and Shannon, thanks for the reply's… Shannon, just sent you a reply PM before I saw you had reposted.
My issues seem to mimic Little Grizzly's somewhat… the brakes never seemed to really engage/turn like they should, then after throwing a track one day, I put it back on, and “viola” dozer wont turn. To make it worse, left brake does nothing when applied, and right brake ceases both tracks when applied.
And yes, they are the foot pedal style. I'm in Chico, CA, and beginning to believe this may be out of my scope, so now trying to (A) diagnosis the problem and (B) find somewhere somewhat local that can address it… Naturally it broke right in the middle of a huge project!
