Commercial hydraulic motor (M350A)

A leisure boat owner came to us with a Denison hydraulic vane motor for inspection because it was not rotating properly and there was excessive oil from the drain line.  Upon inspection the motor was found to be uneconomical to repair.  We quoted the leisure boat owner for a Commercial hydraulic motor (M350A) as a replacement for the Denison hydraulic vane motor.

A Commercial hydraulic motor (M350A) was built in our workshop to suit our customer's specificiations, using the following parts:-

323 5133 202   shaft end cover
323 3120 100   port end cover
323 8222 100   gear housing
323 2922 250   gear set
391 2082 032   dowel
391 3681 035   check assembly
391 2181 999   name plate
391 0381 077   bearing
391 1432 004   drive screw
391 2686 065   snap ring
391 2185 068   thrust plate
391 0482 308   bush
together with adaptors, washers, seals and studs.

The motor was tested on our in-house test rig at 1000 rpm, dual rotation.

Our engineer visited the leisure boat and installed the motor.
