anyone know if its a hard job to replace a broken chain on a 743 bobcat skidsteer??

I suspect it is similar to my 642 which is a few hour job consisting of draining the chain case oil, pulling off the cover, cleaning out the chain case, pulling out the old chain and putting in a new chain with a master link and then buttoning everything back up and addiing oil. This assumes there is no trouble to be found in the chain case besides the broken chain. You might also want to consider replacing all the chains while you are in there. If one broke it's likely the others are on the way out.

Like Cyclone said the key is to get all clean so you can look for any other damage, I think that uses #80 chain, they make that in a std and a heavy duty, you want to use the heavy chain, Be sure you pick up a master link and a half link, you want the chain tight, Get the wheel off the ground and see how much movment you have, It should be very little

Make sure you check your axle bearings while you are at it. If the bearings are sloppy, you might just break your chain again.
