AIR LOCK ???

[rj100]

I installed two new lines to the cylinder that curls the bucket on the bucket on my sc2450 cub - yanmar tractor. Now I can't get the bucket to work, all other controls work fine. Would appreciate some help. Thanks

If you have quick disconnects in the lines make 100% sure they are both fully connected.

If the bucket fully dumped and staying there? If yes you may have crossed the two lines. With a regenerative dump system it would dump but not curl.

If neither of these and system is full of oil the cylinders should move. They may be slow and jerky until air is removed but still should move.

Ditto what oldnslo stated. Air will not lock hyd operation but merely slow down the function.

Hey guys , I figured out the problem. When the hose got made they double crimped one end of the hose and closed the hose off. No fluid could get through the hose. They made a new hose and all works fine. Thanks guys all the answers.
