026 to pro oiler clutch drum prob

[TreeLogistic]

I bought a 026 that had melted the old fixed non pro oiler. It didn't have the heat shield washer, not sure if they came with them. The break band was heat damaged and the clutch drum. Figured if I had to replace all those parts I would just upgrade to the pro style oiler. I didnt replace the 1121 clutch, did buy the pro oiler, worm gear, steal bushing, washer, clutch drum (with the slot), and break band. Put it together thinking I may not be using a 046 for everything, wrong! The clutch drum doesn't sit deep enough to engage the worm, sits about 1/8 in too high. Do early models have different drums? I did see talk of different ser numbers while I was looking though threads, thank you for answering.....

Did you try without the big dust washer?

I only ask cause i just rebuilt a 039 that never had the washer either and i ordered one. Put it on and nothe would line up propperly.

Yes, it takes a different drum.
I have never converted one, some others here have I think.

Depends on the clutch. That washer is for protecting the oiler if the clutch springs break and release the weights on a clutch without wings. Newer clutches have wings and no washer. It’s not interchangeable and goes with the specific clutch design.

I always thought that washer was to keep chips away fron seals and engine. Never thought about the springs letting go. Good info. Thanks

Here is a couple random clutch tech bulletins.

The clutch drum on the PRO oil pump is deeper in towards the oil pump to pick up the pump drive arm.
