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.

Hydraulic Repairs - hydraulic motor (MHA1400C107BV1512226)

Roll on the good weather and a day out at the fairground ...

Today our engineer is delivering a repaired HTL hydraulic motor (Hydrostatic Transmissions Limited) to a fairground ride owner.  The hydraulic motor (MHA1400C107BV1512226) was sent to our workshop and upon inspection was found to have a broken output shaft and worn cylinder block.  A new shaft and cylinder block were fitted, together with a seal kit, oldham plate, bearing cup and cone sets.  After re-assembly the HTL hydraulic motor was tested on our in-house test rig and then prepared for despatch to our customer.

P&R Hydraulics has been doing hydraulic repairs for many years.  Since purchasing Hydraulics Direct (Essex) in 2009, we branched out into HTL hydraulic motor repairs and over the years we have gained a good reputation for these.

Case 721 CXT Loading Shovel - hydraulic repair

 

Case 721 CXT Loading Shovel

A customer reported a fault wth their Case 721 CXT loading shovel and asked our engineer to visit the site to inspect the hydraulics on the machine.

The pressures to the joystick, from the joystick to the main spool valve, and in the main spool valve were fine.  The flow from the joystick to the spool valve appeared poor at first, but improved with time.  The spool valve end cap for the lift section was removed and the spool checked for operation.  Next the loader arm isolator switch and solenoid coil were both checked and found to be OK.  The main spool valve pressure relief valve was removed and dismantled, upon which the seal and internal parts were found to be broken.  A replacement pressure relief valve was fitted and set at 190 BAR.  The hydraulic tank was re-filled with hydraulic oil and the levels checked.  Finally, the machinery covers were replaced and the machine checked for operation.  Satisfied that everything was in order, our engineer left the site.
