I followed the pictures today to take apart my left rear 4150 and want to say what a great series of photographs.
I didn't make the bent rod and was able to take off the circlip by putting one screwdriver in through a hole on the inside and bracing the clip, then prying with another screwdriver on the outside of the clip to just move it off enough to get it with a needlenose plier.
Then I used about a five inch spike to hook behind the gear. I gripped the spike in a pair of vice grips, put the head of the nail behind the gear, and tapped lightly to get the gear over the burr.
The long thread came out manually and carefully, and is now sporting a new layer of lube.
The worst thing I found was the little plastic box that holds the motor leads where they plug into the lead coming from the controller. The plastic is totally disintegrating, has leaked, the screws inside were rusty, and I am going to be coming up with something better... Maybe a tube of tygon tubing with the leads inside and filled with sealant? Tubing of some sort for sure to go over the connections.
Tomorrow I open the motor box and check out that part, then on to the next jack.
Hope there isn't anything too different with the 4500's on the front.
thank you, Mike
