Just finished taking the drums off the 50 3600, a job in itself. but the question is, on the one 50 it has the huck brakes. no surprise there, but when they came off the spring was broke on one and had to force the adjuster on the other, so of course you know that that one is trash.... so went down and brought up the other 50 figured we could use the parts of it, well guess again it has the bend ix set up,, don't understand that one either...well still have the 47 4100 and it looks like the huck brakes on that... question is will the parts cross from the 47 over to the 50 before i take them all apart.... cannot find my books since we moved into the new house.. any help .....
