Some corrections:

Step 1 -- Suggest (as the Service Manual does) using a flat-blade screwdriver and tap it with a light hammer to drive the drip ring off.

Step 2 -- the correct size pin punch is 5/32"

Step 3 -- Using two flat-blade screwdrivers, one on each side, pry off the planetary.

A plastic spudger is likely to break. Two points of leverage opposits each other distributes the load and prevents to the planetary and its shaft.

Step 11 -- The proper punch size is 3/32"

Steps 12 & 13 -- There is a washer on each side of the worm gear. Retain these and place one on each side off the grar when reassembling.

Very useful reply.

Step 3: I needed two flat head screwdrivers to pry off the planetary gear.

Step 9: Recommend adding a new seal for the upper housing and new food grade grease. If you have plastic chips from the broken worm gear, you won't want them damaging the new worm gear. Also, if that grease is black its probably time to replace it. Happy Baking!!!

Cheers Finkerbell,

Very helpful info, as was the main part of the guide.

Not sure what model number I was working on, but when I l lifted off the motor housing, there was still wires connected to the base.

Just be careful at this stage in case you have the same...
