Case 1830 occasional arm+bucket inoperable

[txtmblwd]

i've noticed a couple of times i cannot get the bucket or arm controls to move however i can still move freely, also i do not hear any noise or vibrations when attempting to operate. However if i try again to operate later they will work fine both the bucket and the arms. Also noticed that its leaking some fluid im guessing hydraulic howver i cant pinpoint the location any ideas?

Is this machine new enough to have electric safety interlocks to prevent the lift/tilt working if it detects you are not in the seat or have the seat bar up?

Does it do it if the revs are up higher too? Just wondering if you may have a bad hydraulic pump. I'd still expect it to work if it was worn, just slower.

One thing to check is the splines on the input shaft on the pump. The pump runs off the crank so you will have to take the radiator out to check it. If the splines are rounded out that is most likely your problem. If you can get your skid loader to move the bucket and arms try first try lifting something really heavy. If it stops working the connection between the engine and pump is slipping kind of like a loose belt on an alternator that doesn't charge the battery. You can just get the shaft for the pump and the part the female end that drives it from case but I just replaced the whole pump because the shaft was about half the cost. It wouldn't hurt to shop around. I'll try to check this web site every day for a week if you have any more ?'s that I might help you with. Good luck
