Sauer Danfoss hydraulic piston motor repair

Model No MMF025

A Sauer Danfoss hydraulic piston motor (MMF025) was brought into our workshop for repair.

Our engineer dismantled the motor, and all parts were cleaned and inspected for wear.  The motor required a new shaft and a reseal.  Once all the necessary parts were renewed, our engineer re-assembled the motor and tested it on our in-house test rig.

Not only do we repair hydraulic units, but we sell them too.  P&R Hydraulics holds an extensive stock of high quality hydraulic supplies.  These items are manufactured by the most trusted names in the hydraulics industry today, including Sauer Danfoss, Turolla OCG, Parker Hannifin, David Brown, Webtec, Walvoil and Cassapa.

Model No GE-5681

A CAT spool valve taken off a CAT IT 12F wheeled loader was brought into our workshop for inspection.

The spool valve was dismantled, all parts cleaned and inspected for wear.  Our engineer found the body seals to be missing or worn; the shock valve (tilt) was not working correctly and the steel balls had worn part of (lift) dentent.  All the necessary parts were renewed.  The spool valve was re-assembled and tested on our in-house test rig.

Hydraulic Pump Inspection

Model VT6CM082R00C1

A customer brought in a Veljan hydraulic pump (model no VT6CM082R00C1) to our workshop for inspection.

Our engineer dismantled the pump, and all parts were cleaned and inspected for wear.  The cartridge was found to be severely worn and the pump was considered beyond economical repair.

A new Veljan hydraulic pump (model no VT6CM082R00C1) was supplied to our customer.

Hedge cutter - hydraulic pressure test

Our engineer was called to site to check the hydraulic pressure from the tractor to the hedge cutter.  The pressures from the tractor spool valve and from the valve port to swing over cylinder were checked when the hydraulic oil was cold.  The same hydraulic pressure test was performed twice when the hedge cutter had been working.  No faults were found.

P&R Hydraulics offers an on-site service for customers based in East Anglia because we understand the need to reduce machinery downtime and keep costs to a minimum.  Our hydraulic engineer will travel to your site and diagnose the problem, where he will continually communicate with you regarding any necessary action.  Where possible a repair will be performed on-site.  However, at times it is necessary for a hydraulic unit to be brought back to our workshop for repair and test.

We will consider site visits further afield – please contact us with details - tel 01603 424880 or mail@pandrhydraulics.com

 

 

Pig Feeder - hydraulic modification

We received an enquiry regarding the hydraulics on a mobile pig feeder.  Our hydraulics engineer visited the site, where he made up the hydraulic hoses as required and fitted them.  The hydraulic valves were mounted as required.

In order to check the operation of the hydraulic system, our engineer connected his power pack to the machinery.  Once he was satisfied the hydraulic system was operating correctly, the power pack was disconnected and he left the site.

Drilling Rig - Hydraulic Fault

Drilling rig
 

Our experienced hydraulic engineer was called out to site to investigate the hydraulic fault on a Hanjin P6000 drilling rig.


He removed the tank top filter lid and found the hydraulic oil to be contaminated with excessive amounts of brass and metal.  The hydraulic pump was disconnected for repair, the hydraulic tank cleaned and all filters removed.  The next job was to remove as much oil from the hydraulic system as possible.  The return filter assembly was cleaned and the return filter and small suction filter were renewed.  He cleaned the large suction

filter, as best possible.  The repaired hydraulic pump was re-installed and re-connected to the hydraulic pipes.



Our engineer left the site when he was satisfied with his work.  The customer was to fill the tank, run and check the hydraulic system.

Spool Valve inspection

A McConnell power arm spool valve was brought into our workshop for inspection.

Our hydraulics engineer inspected the valve.  In order to test it, all port adaptors were removed first.  The valve was connected to our in-house test rig and the mechanical actuators worked correctly with no leakage.  The spool valve was reassembled and returned to the customer.

No job is too small!  Our experienced engineers can inspect, repair and test a wide variety of hydraulic motors, pumps and valves using our in-house workshop and test rig.
