Toyota Huski 4SDK 8 - Can I get help to identify weird noise

[Nick0009]

I'm having trouble getting my right side wheels to move. They've been a bit touchy for years, but I little rock forward or back has always done the trick. Now the right side seems to be locked for the most part. If I put the parking brake on and then release it I can usually get about a metre or less of movement before it locks up again. When the machine moves, I can hear a "ka-thump, ka-thump" sound each time the wheel goes around, and it looks like the parking brake link jiggles in time with the "ka-thump". I'm thinking its either a bent locking pin for the park brake or a chain problem. Please help me ID the noise. https://youtu.be/zQ-9MMqRCt8 Many thanks!

As you say messing with your park brake generally lets you move a bit, i'm wondering if it could be the brake sticking on. I guess it could also be a chain or sprocket issue. I think you will need to open the cover on the chain case and look to see what it is.

Yeah I think so too. I had a look in there yesterday and the lock pins weren't retracting far enough. I've adjusted the park brake and now they go in further and I can drive around no problem. https://www.youtube.com/watch?v=Xnmi99n36H8

Interesting, i never knew that is how their park brake worked, makes snese it does one side at a time if it's out of adjustment. Bobcat has a wedge that locks both at once.
Hopefully that is your problem solved!
