Oil pump gear

[Kyle_T]

Pulled my motor and noticed I chipped the plate on the oil pump gear/sprocket. I haven't taken it off yet, but is the plate separate from the gear? I tried searching but can't seem to find the gear or a part number for the gear and/or plate. Does anybody know where to get one?

That is all part of the sprocket. It's part number MD124762 from your favorite OEM parts vendor and I'm sure you can find them used through Miller Imports or a junkyard.

This sprocket broke a month ago on the highway. I threw time and broke...everything. Replace asap.

so if it's chipped like that will it be guaranteed catastrophic failure ?? I kinda have the same chip.

I've ran them like that with no issues. Buttt, if you had some spare change and the belt off, why not replace it

ive spent sooooooooo much with this current build it's really not funny so to not lose it on some thing so small
i guess ill put it on the list. but for now it will stay. Is the part number above for both 6 and 7 bolts?

Mitsubishiparts.net says it works with just about any 4g63-4g64 engine. I dont know first hand though...

Yes they're the same.

MD135005

That is the new part # AND it a interchangeable part for 6/7 bolt

I think the link above is the cheapest. Extremepsi wants 47.xx compared to 45.xx

Take it from me first hand. This exact sprocket broke and caused catastrophic failure to my engine. Spend the $40 and replace it.
