440 Bearing Spacer

[EtzCutter]

I've had the oppurtunity to grab my first 440 with miscellaneous parts missing from the saw. When I remove the clutch I find the oiler along with the worm gear. My question, did all 440's come with a "bearing spacer"?

What is the purpose of the "bearing spacer"? I know that my 310 and 039 don't have this item between the clamshell engine and oiler.

By bearing spacer are you referring to the sleeve on which the oil pump worm gear rides on? If so, yes- all 044s and MS-440s came with them.

Will someone explain to me why a bearing spacer is used? I don't see them on 660, 360, other pro saws...
