Have a computer challenged friend who asked me how to remove the driven gear from the brake drum as he will have to replace his drum. I found the procedure in the Service manual under overhauling transmission and will be passing that info on to him, but does anyone have any tips for him to make it an easier job? (its a 14) What type of puller works best? Is a special Ford service puller required?
The factory Ford puller works great - I can borrow you one, if need be.
Steve, What's the number on the factory puller? I may already have it.
Factory puller is not mandatory. I use a split bearing puller. Works great. BUT you need a slug to fit inside the brake drum shaft to pull against. I made a steel plug that fits into the id of the brake shaft bushing, with an od small enough for the gear to fit over.
Hello Terry: I saw the post this morning and enclosed is a picture of the gear puller. it works for all model T's and not just for a particular year.
I think the real challenge is holding the drum assembly when trying to remove a stubborn driven gear.
They dont always come off fairly easy.
I think another question would be how to hold the drum assembly.
One way is to attach the above puller then clamp the puller in a vice by one jaw. This lets you crank the puller without trying to hold the drum assembly.
Ditto what Tim stated to - secure the puller in the vise.
Thats one way to do it Tim.
If I remember the Ford shop manual showed a drum clamping device mounted on a bench.
The last gear I removed from a drum assembly I had to use a cheater bar on the wrench to get it off. It was tough the whole way to remove it.
The bench wasent attached to the floor so I had to block it from moving. This was the hardest to remove compared to the others I had removed.
I guess the tolerances were borderline on either the gear or the drum shaft.
I have to add that this is one of those instances that Ford assumed each shop would have the type of holding device as shown in the manual.
You have to use another method from time to time and use your imagination.
Thanks to all. I have the type puller shown by J and M.
Terry : I use this homemade puller .
I use the Ford puller and put the square-head bolt in the vise, then turn the puller arms with a large Crescent wrench. Works great for me.
I use a three leg puller with a hydraulic ram. The ram enables greater pressure to be exerted without the hassle of trying to hold the drum assembly. The pressure is applied gradually, with little real force needed on the nut. I can hold the drum assembly with one hand and work the wrench with the other.
As an aside, the puller set is an English Sykes Pickavant brand, top quality stuff, still in an unmarked toolbox. It was marked as a ball joint remover and priced at $90 in a pawn shop. They didn't know what it really was, and the jerk who stole it didn't know either, or he would have held out to a figure closer to the $940 I was quoted for a new one.
