Customer Question

Good morning,
I have a Hubota L3700 with LA463 loader.
Has no lift unless you are curling the bucket.Dealer sold me a kit for the valve for $153.00 which did nothing.
Any ideas would be helpful
Thanks

Have you removed the linkage from the valve and worked the spools manually?

Expert:  Curtis B. replied 1 year ago.

The boom spool is not shutting off the fluid when it is moved. That is why it only works when the bucket spool blocks the flow.

Expert:  Curtis B. replied 1 year ago.

Either the boom spool is not moving far enough, or the valve is damaged internally.

Expert:  Curtis B. replied 1 year ago.

The spool has to block the flow from pump , and direct it to the cylinders.
