Thanks guys. I feel a lot more sure of whats needed now. I've got a engine hoist and might have to do it outside. I also have a pressure 1600psi washer that might help with cleaning it out. I plan on cleaning, and then cleaning again and again. That sounds pretty definite from you guys. I have a air compressor and air hammer also to drive out the pins. I don't know if she has the holes under the seat drilled for the pins yet,if not they will be. She's already been converted over to electric start. I will be changing the genny to alt and beefing up the wiring. Yes I will save all the parts for her.

Take your time getting the build-up out of the cavity before attempting removal.  It can get pretty crusty in there.  I like Steve's idea of using a chain hoist.  I usually use a tire iron and get leverage on the back of the final drive and pry it out.  If the cavity is clean, it's a piece of cake.

When you change those  brake bands you may say a few words that are not wise and wish you had forgot. The tounge is a powerful thing.

Foot brake arrangement is pretty easy to install.  Biggest problem is getting the old brakes out and new brake band installed... I  poke out all the mud dobbers and wasp next that you can see first.. Get a garden hose and wash out thru the 1 inch hole on the bottom.. You have to get EVERYTHING out to get the band off.. Once that is done you need to get the horizontal pins out that hold the bands in. The pins are installed from the outside, toward the center of tractor. Many are a blind hole. SOmetimes you can see where the boreing bar ( drill) started to come thru the backside of the casting ( under the seat by the differential)... I like to take a 1/4 inch bit and drill into the housing from the backside toward the pin... then you can pound them out from the back.. After the 1/4 inch hole, enlarge it to 3/8 inch... get an air chisel with a pointed tip and hammer them out... don't forget there is a snap ring on the inside between the housing and the band.................... once the pins are out, then you get the  brake bands out.. I like to park under a rafter in the garage and pull them out with a 3/4 ton come-along.. use some #9 wire and tie into the pin hole to attach the come-along hook..
 
after the bands are out, wash the brake drum with  solvent to get any oil off of it. I have put the tractor on jack stands and rotated the tire to spin the drum and sand or file it as it rotates, if it has a slightly rough surface.. If its TOO bad, it should be pulled out.
 
to install the new bands, run the #9 wire under the brake drum and up the other side. tie the wire to the band, and the come-along and use it to help pull the new one thru.. Make sure which is front and back.
Like them all, but love the "B"s.

Hey guys I plan on converting my 38 B to foot brakes this summer. I have all the parts, pedals link rods, pivot toggles and all. I plan on notching the fender/seat frame rails and also add a WC Monroe-Matic seat setup. I have done a lot of reading on brake replacing and conversions on this site mostly. Any words of wisdom would be greatly appreciated.
