2538 Main Hydraulic Pump failed

[CDBUG]

Hello all, new member in the State o' Maine.....my issue with my Mahindra 2538 is the main hydraulic pump [#12625103100] has failed. The Dealer does not stock one and after many searches by them and me it seems nowhere to be found. Any direction or help finding one would be greatly appreciated!!
Thanks, Chris

That pump comes up on Bill's Tractor HYDRAULIC GEAR PUMP FOR 2538|2540 MAHINDRA TRACTOR (12625103100)
if I'm not mistaken....

 

[CDBUG]

Thank you, it does list as in stock there, but when we contacted them they NO HAVE!

 

[SimpleSimon]

wow, that's a bummer!

 

[CDBUG]

Yup! Wicked Bummer in the Summer!

Can a competent Machine Shop retool these pumps? The Dealer didn't think that was the way to go but with no new pumps available......?

I'm no expert, but IIRC that pump is an elec driven pump, not a gear driven pump (I could be wrong). If it is elec, seems like you could buy a NON-OEM pump, fabricate a bracket to mount it, and you're back in business.

I did that with the hydraulic control valve for my 2538 and it works fine.

Good luck on your search!

Yes duffer thanks, one issue is it's sitting in the dealers shop, I'd have to sell that idea to him but with no availability of stock ones that may be the only way.

Electric driven pump? How would that work?

CD
To attempt to replace your existing pump you would need to know the following information.
Mounting pilot diameter and bolt pattern.
Shaft style: diameter and number of teeth on spline or keyway size.
Displacement typically stated in cc/rev.
Direction of rotation
Port style and sizes

With this information you could look for options with knowledge that port sizes and locations could be different. Mounting face, shaft must be the same.

Evidently, not real well. I did some more research and discovered the hydraulic pump is indeed, gear driven.

I didn't say it was a good idea...(lol)

Sorry, I just had to ask. I still wonder where you came up with that.

I've seen a lot of various pumps that were electric driven. Thought why not a hydraulic pump? Never really looked at the 2538 hydraulic pump that close cause I never had any trouble with it.

Maybe I'll have to invent one.

Thanks for the replies, it's now in the hands of a Machine Shop that I have done business with before...

Thanks for posting about this. What happened to the pump? Do you have pictures?

Sorry, didn't take any pics....the teeth on the pump look like a hammer and chisel was used on them. It seems it just" S the bed." Amazingly the inner gear mates with it fine...no damage on it. Mechanic said that it is made that way to sacrifice the pump teeth instead of the inner engine ones..... they got that right! [BYW.. this 2538 has approx. 900 hrs. on her]

there is a formula for it but 10gpm at 2500psi is some where north of 10hp (14.5 hp i looked it up) so that would be a heck of a electric motor. hp == psi X gpm /1714.

I know they use different engines but did you cross reference with TYM since that is who makes the 2538?
Perhaps the housing and bolt pattern are the same....

Great idea, but I looked it up on TYM's site and the TYM pumps are split and on the port side while the Mahindra is starboard and the two pumps are in series.

I am going to tell you something that is not going to make you happy.
I work at a Mahindra dealership and parts have been murder to get as well as tractors themselves.
The 2500/2600 series Mahindra's are some of my favorite tractors Mahindra puts their name to.
Currently, TYM hates Mahindra and Mahindra hates TYM. They are dissolving their relationship and Mahindra has gone into a joint venture with Mitsubishi to build a new plant in India to produce what will be called the K series tractor.
I will chk at work to see if we have an extra pump for the op. I am not hopeful.
