Factory Diff Lock Pump Replacment

[datrat]

Well still no luck finding an affordable replacement pump. But I have found out that these pumps are used in a few other cars.
Here are the makes and part numbers I have found
Mitsubishi
3590A011 MR453610 MR953484
Suzuki Vitara / XL7
2794065D03TAO 2709465D02 2794065D03 2794065D00

Chevy Tracker 91177534, 91175575

KIA 510303e100

I just thought I would list these as a reference I case others might need to find a replacement.
Cheers

No, the Pajero Sport has an E Locker fitted.
Low pressure pump is used on the Gen 4 Pajero, Challenger and Triton.

Fitting a Pajero Sport E locker to a Challenger may be possible since it seems to have the same solid axle housing or it should be possible to fit a complete rear disc to disc axle assemble from the Pajero Sport onto the PB/PC Challenger. However most wreckers want about $1800 for the assembly and this is the price you can purchase a Harrop E locker for so there are no real advantages that I can see.

To changeover the diff centre, the spline count on the axles and the axle lengths would have to be identical. You would be able to cross reference part numbers on Partsque if you had the VIN of the donor PS.

ok, seems the harrop is the only option for a dead OEM locker.


I need to check my pump as think that is my probelm also, if its only few hundred makes sense to replace the faulty pump..

Sorry Cookie, I misunderstood your question.

The PB PC Challenger that is fitted with a factory diff lock has a different CW&P gears, different bearing sizes, different axle lengths and different axle spline counts to the PB /PC Challengers that do not have a factory diff lock. I am reasonably sure the aftermarket diff locks from Harrop, ARB and TJM only fit the Challengers without the factory diff lock.

It seems the cheapest option is a $300 pump from Partsque or a secondhand pump from a wrecker.

Good prices on that website.
The suzuki pump p/n 2794065D03 is the cheapest $206.38 aud
The cheapest mitsubishi p/n 3590A011 is $442.04 AUD ($300US)
I'm thinking to get the suzuki pump to save all the messing around.
Im also thinking of relocating the pump and breathers into the rear of wagon near the jack.
Has anyone done this?

how did you go?


got mine heading in for service next week and they are having a look at the pump/diff to see if they can figure out whats up..

[cookie9]

mechanic just looked at the diff, the pump is working fine so he thinks something internal that is not letting it fully engage.. Further investigations required...
