I have 4 relief valves that I took out of my pumps Im sure they were 5000 psi I dropped mine down to 3500s when I put the larger wheel motors in ...there was no issue with them at about 3000 HRS ...If you wish to try them and they are compatible I'M happy to send them to you if it helps to get...

hey there Maddy Are the shafts on top of the transmission pumps fully actuating ...I had a similar situation where the servo rams that turn the pintel shaft on the pump wern't fully extending One of them was bypassing in one direction That caused the shaft not to turn in one direction and hence...

Morning James will chase up on the manuals ...is the pilot valve moving the pintel arms on top of transmission pump ..via the two servo rams ie, are the two servo rams on top of transmission pump activating when you move the Tbar forward backward left right ? can i ask what state you are in qld...

Yeah it would be good to hear some more input regarding these machines ...Before you hook the Servo Rams up you may want to try moving the pump shafts at low Idle....That would effectively by pass the Pilot Valve under the TBar ....If all systems are go then its most likely there is a problem in...

Hi Gremlin Its just a thought As long as your machine is Jacked up on blocks .....You may be able to screw a long bolt into the lug on the pintel arm of pumps and operate them manually .....Biggest problem there is its such an awkward spot to operate the pumps and watch what the wheel rotation...

Gees ...That quote to do the pump seems way out there......I dont think they are that much NEW !!!! ......I'd say you are going to firstly have to get the servos to synchronise on the pintle shafts first ....small adjustments there make a big difference to its travel behaviour ....when they're...

If there is anyone else out there in BHB world that has experience with these machines please Chime in Im in no way a Hydraulics expert ....So please correct me if you pick up on anything ....My experience comes from pulling spanners on my ol' girl ....Had the Engine and Pumps out twice Thats a...

Hi Gremlin The valve under the T handle is the Parker valve I havent had mine apart so not sure if thats part of the equation here ...The seals on the plungers are a square seal odd size ...Parker dont list them any more according to hyd shop i enquired at O rings wear quickly ... not sure as...

apoligies there that should have been ie 9 oclock to somewhere around 11 - 12 Cheers

Thats a good place to start Any slop in the mounting is movement lost on the Pintel shaft .....Without taking floor plates out and measuring mine ..I cant recall how much movement the Servos have ....When you disconnect the servo from pump ..you might be able to measure the travel distance by...

Hi Gremlin second attempt to post first one was lengthy and didnt launch 1 ..Servo Rams are anchored to bracket with a spherical bearing ....it could be floggged out ...Valve under T Bar is a Pilot control valve ....it tells the servo rams what to do ..IE, Fwd Rev Left Right ..It activates the...

Hi Gremlin If the wheel motors are performing as usual in Forward direction I'd be checking Servo Cylinders for leakage / Lugs on Pintel shaft arent loose / and the control valve The control valve should be a Parker SER no 05058958 MOD VRC291R200 . Thats the no on mine ..All enquiries to this...

Hi Gremlin Sure would be keen to know what you come up with there....could be bypassing in servo cylinders or as you say the control valve...Keep us posted on that one Cheers

Hi Gremlin .. Is Fritz 11 a BHB ? Yes thats right about checking hyd oil level. I think they take about 150-175 litres . There is also a suction screen behind round plate which is located behind right hand rear wheel . Screen should be checked if you have had any system failures .. I put a heavy...

Big Thanks to Tazza Our moderator down under was able to put me in touch with Wazza who was chasing some parts for a BHB . Parts being sent to him this week so hope he gets up and running ....Cheers Tazza
