Bobcat 743
OK, I am new to this forum and to owning a bobcat and now it looks like I made a mistake in buying one... I bought this one about three weeks ago and had to put a battery in. I really haven't used it more than 3 or 4 hours and when filling the bucket with dirt, I hear kind of Bang noise, and all the hydraulics failed.. It won't move, bucket won't move, but the engine is running fine, in fact, it seems like there is no load on it... Is there a CV joint or something simple that could cause this... I don't want to start ripping it apart for nothing.. Thanks

Maybe the hyd pump shaft spline is stripped or broke off?

is the 743 bobcat one of the ones that have a drive belt from the engine to the pumps ? cause if the belt blew that would explain what happened .

743 has a CV (double U-joint) connecting engine to pump assembly.
