Chainsaw stump grinder swap back

[NickinMids]

I bought a terminator stump grinder with 661 engine ex hire

I'm in process of setting it up with a bar and chain for some big trees

 

I've bought the clutch cover with the sprocket to replace the one with the solid oval which drives the grinder

 

My question is (if someone knows?) is there normally a groove in the clutch cover that drives the oil pump?

Someone else put it together for me but I noticed the stump grinder cover doesn't have one which makes sense as the grinder doesnt require oil

 

Anybody know about switching these attachments

Yes should have a slot for the worm drive for the oil pump to fit in to,

Is there a worn drive in the saw behind the clutch to drive the oil pump,?

Is there a oil pump fitted in behind the clutch?

Yes I believe there is.  Would make sense for the custom clutch cover to not have a slot. 

There has to be NO oil in the saw when using with the grinder attachment.   I'll ring Predator tomoz and check with their tech guys.

 

Many Thanks Spud
