High speed gear for hydraulic pump case 885

[FarmerD89]

Has anyone any information about fitting a new high speed gear on my hydraulic pump your just revving the tires off the old
Girl for any hydraulic flow, it’s had a new pump in the last 100 hours so it’s deffo not that.

Have you gone through the usual things - checked hyd oil level, changed filter, checked the MCV etc? including the relief valve?

Look for a s/h 4240 pump and the gear will hopefully be on it

What would you do to check the mcv and relief valve?

I would start by putting a pressure gauge on a remote and see if you’ve got at least 2200 psi and ideally a flow meter as well, so you can measure pressure against certain flow rates.

Have about 2000 pso so a little low, manual says should be 2500, don't have flow tester though

Basically steering and hydraulics are terrible unless it's got lots of revs, slow to lift, and then not got great lift capabilities, will still tip a trailer but not very quickly, thinking new pump with high speed kit would sort it

Why not just replace like for like ? Do you actually need the extra flow ?
IF you fit the high speed gear to an earlier tractor you will get more hydraulic noise, also if your tractor hasn't had a new transfer pump recently it would be a very good idea to fit one IF you go down the high speed pump route.
The reason for this is an old/original transfer pump will be worn and it may not keep up with a higher output pumps demands.
What happens is you get odd faults because if the new pump, operating at higher output can't get enough oil it's sucking air because quite simply the transfer pump cannot keep up.

As for testing you need a flow meter to the job properly, it's great to know the high pressure RV is working correctly ( 2500 psi ) but with hydraulics flow is everything
