Pajero Owners Club of South Africa

Hi All,
Can anybody please advice,
I want to change my oil pump on my 3.5 Blister and at this stage the heads are removed.
Is it possible to change the pump from underneath as I do want to take the engine out as I do not posses the facilities to do that or is it a must to take engine out to do this job.
Your advice please.
Kind Regards

The guy who did mine took the motor out, but he said it was just easier that way.
