Raptor strawbedding machine - hydraulic repair

Raptor strawbedding machine - hydraulic repair

A local farmer was having problems with his Raptor strawbedding machine and called our hydraulic engineer out to site. The Sauer Danfoss OMS250 motor (151.0483) was removed from the machine and brought back to our workshop for repair. A further site visit was needed to refit the repaired Sauer Danfoss OMS250 motor (151.0483) and a new Sauer Danfoss dual cross line relief valve (158H8031). Our hydraulic engineer left the site only when happy that the Raptor strawbedding machine was working satisfactorily.

P&R Hydraulics is proud to offer an on-site service to local companies and we will also consider visits further afield - please contact us with details (tel: 01603 424880).  Our in-house workshop and test rig enable us to inspect, repair and service many makes of hydraulic pumps, motor and valves.  We are an authorised distributor for Sauer Danfoss and can supply their high quality hydraulic products, as well as repair their units (as mentioned above).

Parker Torqmotor hydraulic motor inspection

A local fisherman brought in a Parker Torqmotor hydraulic motor for inspection and possible reseal.  Unfortunately the motor was beyond economical repair because the shaft was badly worn.  The fisherman ordered a new motor and needed it urgently because he was due out on the open sea in two days time and it operated the winch used to pull in the crab pots.  We did not hold the Parker Torqmotor hydraulic motor in stock, however, our sales team managed to source one and arranged for a next day morning delivery.  Our customer returned to collect the hydraulic motor and kindly gave us a tray of freshly cooked crabs as a thank you.

It was all in a day’s work for our team, but  it was lovely to know it was appreciated and to receive such a kind gesture from a satisfied customer.

Case 721 CXT Loading Shovel - hydraulic repair

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.

For more information on our on-site service, please contact us on 01603 424880.

Winch assembly repair - site visit

Winch assembly repair - Danfoss HTP25 hydraulic pump


A new customer contacted us to purchase a Danfoss HTP25 hydraulic pump.  Upon finding out more about P&R Hydraulics' site visit service, the customer instructed us to install the pump onto a winch assembly.

Our engineer travelled to the docks and boarded the vessel that housed the winch assembly.  The old pump was removed and the winch assembly was inspected.  He installed the replacement Danfoss HTP25 hydraulic pump and re-filled the hydraulic tank with hydraulic oil.  The winch assembly was re-assembled and checked for operation.

CAT wheeled loader hydraulic repair

CAT Wheeled Loader (Model No IT12F) - hydraulic repair


Our engineer was called to site to inspect the hydraulics on a CAT wheeled loader (model No IT12F).  Upon inspection he found the spool valve to be faulty.  He was unable to repair the spool valve on site, so he returned with it to our in-house workshop. 

A further site visit was needed to re-install the repaired spool valve to the machine.  Our engineer checked the pump flow and valve maximum pressures.  The machine operation was checked and once satisfied that everything was working as required, our engineer left the site.

P&R Hydraulics offers a local on site service for the East Anglian region.  Site visits further afield will be considered - please contact us with details.

Model No 112-1067-006


A unidentified hydraulic motor was brought into our workshop for inspection.  Our engineer identified the unit as an Eaton hydraulic motor model number 112-1067-006.  The motor was dismantled, all parts were cleaned and inspected for wear.  Pitting on the shaft at the location of the shaft seal was causing the motor to fail.  The shaft/bearing assembly was renewed and the motor resealed.  The re-assembled motor was tested on our in-house test rig.
