Compatible Chainsaw Models

This pack of ten worm gears fits Stihl chainsaw models 044, 046, MS341, MS361, MS362, MS440 and MS441. It replaces original parts 1128 640 7112 and 1128 647 2400. Professional users and workshops gain a ready supply for multiple saws.

Oil Pump Drive Limitations

The worm gear drives the automatic oil pump on two-stroke petrol chainsaws. Wear on the gear teeth or the mating shaft will reduce oil delivery, risking bar and chain damage. The part does not fix oil leaks caused by cracked pump bodies or failed seals.

Installation Notes

Replacement requires splitting the clutch side of the crankcase to access the oil pump assembly. Correct meshing with the pump drive shaft is critical; misalignment causes rapid tooth stripping. The pack includes only the gears — gaskets, circlips and seals must be sourced separately.

Questions about this item

Which pack size should I select for my Stihl MS361 chainsaw?

The listing supplies exactly 10 worm gears per lot, which matches the quantity shown for all compatible models including the MS361.

How does this worm gear perform once installed in a Stihl 044 saw?

It replaces the original 1128 640 7112 or 1128 647 2400 gear, restoring the oil-pump drive on 2-stroke petrol models such as the 044.

What part numbers does this gear cross-reference and what does that limit?

It cross-references 1128 640 7112 and 1128 647 2400, so fitment is limited to the Stihl models listed: 044, 046, MS341, MS361, MS362, MS440, MS441.
