So here is my issue, I can not remove/disconnect the FIP from the FIP gear. I have all the hoses off, bolts that go into housing are off, and the FIP main nut and lock washer are off. Got it about a 1/8 of an inch out, the issue seems to be that it will not let go of the gear. in the instructions it says i need a special tool to remove it... and doesn't tell me at all what that is. I have removed several other FIP's. The FIP is a Bosch pump, VE4/12F1150R1038-1, the tractor it is on is a '20' series 4wd 7520 Mahindra. Any incite into this vexing situation will be greatly appreciated.

If you'll look closely at the gear, it has bolt holes in it..
Those holes are meant for a puller.. the pump drive shaft is tapered & "stuck" on the gear..
IF I recall, the drive shaft is NOT keyed & its a "tapered fit".. which means the ONLY THING holding the DS & gear together IS the tight fit..
I may be wrong but either way, its stuck on the pump d.shaft & you need a puller..
LOOK for a key.. look for a slot cut in the gear behind the nut & washer.. no slot=no key..& you better hope to god you timed it correctly..
I'm in the injection pump "biz".. & have bought several of those pump pullers.. the latest one I bought was from Xtreme Diesel online for around 35-40.00.. & its better than the snap--on 1 I have..which cost 88.00..

OH WAIT.. I just remembered, the last Mahindra I did, I wasn't able to use THAT {XD} puller.. the holes were too close..
I ended up using a flywheel puller for a lawn mower.. I also bought THAT online.. I don't remember where, but it has about 4-6-8 different hole positions that you can use for a lot of different screw configuration..
& yes, THAT PUMP WAS keyed & had a timing line on the outside of the pump housing for final timing..
BUT.. the inside of the pump had imploded & was VERY expensive to fix..
IF you would like to contact me, feel free.. I can probably save you 100.'s vs your local repair shop..

Afternoon,
I just bought a 2006 mahindra 5500. The mechanic says i'll need to have the injector cleaned or rebuilt. Any tips on if cleaning is advisable?

The injectors have to be taken apart and retorqued IN A SPECIAL JIG that holds the insides from turning..
There are tiny alignment pins inside.. if u simply try to unscrew it, u break the pins and ur left with buying another injector..(cuz u can’t fix the broken pins)
On top of all THAT.. u need a pop tester to check the opening pressure, spray pattern and leakage..

I’ll send u a prvt msg.

Holloway Bear Cat Having problems getting pump shaft to move out of gear don't know how much pressure I can put on it to remove pump it's on a Mahandra 2011 5525 tractor any help would be appreciated.

I take it u removed the nut and washer from the drive shaft.??
Idk how I’m supposed to explain how tight u need to have the puller.??
I remove the nuts/bolts holding the pump to the block and just screw them back on to keep the pump from taking off when it does break loose..
I’ve also used a wedge or two between the pump and block to “help” the puller..
Good luck

Got nut and washer off. What I was getting at about the pressure on pump shaft and gear before breaking something with the puller. I don't have a breakdown of engine don't know what I'm up against. I have got fip out away from housing about 1\8 inch but no more with puller really torked down does this sound right ? Thanks I try the wedges too. No help from our Mahandra dealer here !

I’ve only removed a handful of pumps from Mahindra tractors.. so I’m no expert with the removal parts of the equation.. & w/o pictures or physically being there, I’m at a loss..
