    I was using the 430 to grade a yard yesterday and noticed a loud clicking noise coming from the right hand side that varied with wheel speed. I only heard it when pushing hard and only in forward not when loaded in reverse.
    Any ideas before I tear into it? Chains on that side worn out? Or maybe just out of adjustment?

    Might be a link is half busted, and has an ear that hits something, but only in the 1 direction... Might be worth it to jack up the side, and see if you can isolate where the noise is , with a helper. Don't know if it has a top side inspection window, but if it does, take it off and get a look at the chain, in motion...;)

    I would check for fluid and tension, I would about guess that the tension needs to be adjusted.

    It's uncanny how the simplest jobs can turn into three-ring circuses. Pop the access plate off and found the rear chain is loose enough to slap the bottom of the case when I jiggle the wheel, and the front chain isn't much tighter. Also there's a thin layer of chocolate milk where the chaincase oil should be.
    Go to loosen the rear axle housing. Apparently the incredible hulk was angry the day he put the nuts on. Between that and the rust my impact wouldn't budge them so out came the torque multiplier and breaker bars. Finally got all the nuts loosened and, with the help of a high-lift jack wedged between the housings, chains tightened.
    Then I turned my attention to draining the soup de neglect out of the case. Unfortunately 3000 hours of bouncing around on demolition debris had smashed the poor little 3/8" drain plug into oblivion, and my attempts to resurrect it only made it worse. So I decide to bite the bullet and drill it out. Right as I break through the bit catches and snaps the tip off. I knock a punch up into the hole and manage to dislodge the piece of bit, and then finish the hole with a new bit, rust-proofing everything in the vicinity in the process.
    This was during,

    And here's inside the case. It's hard to tell but the chain was super slack.

    Now I'm just waiting on the sealant to dry so I can put new oil in it and test it out. All in all it could've been worse. At least it was a cheap job :D

    Between new fluid and proper tension that should quiet it down. Clearly moisture got in the chain case. The poor lube may have contributed to the chain stretching. Might be a good time to just replace the chains since your already there and chain is rather cheap. I snapped a chain on my 440 (I was running a VTS track system on it when it happened). I can say when that chain snaps you are fixing it where it stopped, depending on how the chain wads up in the chain case.

    I'm scared to overhaul my chain cases for all these reasons, but it needs to get done this summer. Luckily I use the machine lightly.

    The clicking noise...I had same noise on my 1845c and it was the parking brake pin on one side that needed adjusted.
