Looking for 4550B backhoe parts breakdown

[3rdidvet]

Have a leaking valve (coming out the valve spool cap) and want to rebuild it. Took it to a hydraulics place and dropped $600 and the problem is worse.

Thanks in advance!

I BELIEVE it's an Ansung made attachment. Closest model I can find is a BH 680, but cannot find a parts breakdown for the hydraulic valve assembly.

Here is the blow up of the 4550B valve, it is available on our website www.NewEnglandTractor.com
