What is the procedure on replacing the brake banks on a H?

Just like the title states guys. Ive got 2 new brake bands for the 1948/49 Farmall H, and cant figure out how to get the old ones off. I am hoping that you are not going to tell me that I have to take the main cast iron cover off.

Thanks,
Craig

Band brake tips-H & M
Remove the pins holding the brake adjuster to the pedal & actuating lever. Loosen & lube them.
Remove the cap screws holding the brake cover; wiggle it & they should come off.
Note or draw a diagram of how the brake band is attached to the cam. Turn the cover over, shake, tap or whatever to get the 2 pins out. If you remove the outer lever & half-moon key the whole thing comes out.
Replace the band & be sure the brake cam pivot shaft works freely in the cover. Oil or grease the pivot the area well and let the excess drip off before installing the new bands.
Remove the brake drum; do not try to remove the bolted-on housing containing the seal. The bull gear inside the transmission has to be removed first to get the housing off.
Using punches, chisels, etc. collapse the old seal inward, if original; it is difficult but will succumb to persistent efforts. Replace with 2 seals per side and place some chassis grease in-between them to protect the outer one from drying out. Polish the sealing surface on the brake drum and re-assemble.
Place a small amount of grease in the hole where the brake pivot goes into the transmission housing. After installing the bands & getting the pedal free-play to about 1", apply the brakes firmly, lock them in place and adjust the set-screw on the bottom side of the cover. (helps to loosen any adjustable parts BEFORE re-assembly) Loosen the jam nut, turn the set-screw in until it touches the brake band, back out 1/2 turn & lock the jam nut. This helps prevent the brake band from dragging, premature wear, and overheating.
