Right. It's not bolted together like most motors. It should have three or four little "tabs" around the outside edge on the bottom of the motor. carefully peel those back and it can open right up. Trick is getting it back together. Done carefully it can be pinched back together. I ended up doing a tiny lil tack weld with a MIG to get mine to hold together tight.

I have some detailed instructions on the DYI for this job at the house. I'd be glad to share with you.
