do you mean the worm drive or oil pump unit?

[spudulike]

From memory when I worked on mine, you remove the clutch and sprocket, remove the allen bolts that retain the pump and then insert larger bolts in three pre tapped holes and tighten the allen bolts that then push the pump housing outwards as the bolts push against the casing.

 

The worm drive is a push fit and should come off with a couple of screwdrivers behind it - there is a manufactures tool, like a puller or you could make one.

 

I do have a service manual for this saw if you want to PM me.

 

Fab saw by the way.

had a brief go with some screwdrivers but since it was brass it was getting scored easly so i think i will take it in to the shop unless i can get hold of the tool, shame as i prefer to try and learn to fix saws myself
