Oil pump question ?

[euro_urs4]

Does anyone know I anyone sells a built oil pump for a aan motor, mine slightly shattered on the inside where the crank keey ways go into it, is a new oem one good enough ? Or is there a better built one with stronger material ?

I have never heard of an AAN oil pump dieing/breaking before so I would think a replacement OE pump would be fine.

Here is some oil pump info for you:

thank you for the info, but i dont know what happened in my case, you can see in the picture that the key ways are not perfectly (rectangular) or whichever shape they are to be, and the small piece of metal is just one piece of 3 that i found that were torn of from the oil pump.

I have had the car for the past 3 years , I don't believe it was in any accidents that I know of, and the front pulley looked like it had a slight wobble , maybe through age unbalancing itself .

Only time I've seen them crack is if they are installed onto the crank slight of alignment and the installer tries to hit the oil pump home with a hammer not realising keyway not 100% lined up.
