Re: 72 450b clutch is good brake band worn
You are going to have to get the tank/seat assy off and take off the clutch housing covers. It is a real pain but I have removed a brake band that way. Too bad all my pictures are gone from the photobucket fiasco !!

I rebuilt my 450B clutches and brakes using mostly REDDIRT's instructions.

Labparamour I was thinking along some of the same lines as you. Since I have both a broken bolt and a stripped hole I'll have to do both ;-( One of the taps I ordered is 5.750 long and that should get me outside the side frame at least. The driving end square is 0.500 and should fit a 0.500 socket e...

I Was just discussing this bolt problem with another JD crawlers member. He showed me that in later builds of 450 larger bolts were used in the side frame to clutch housing. I checked the JD online parts catalog and indeed there are 7/8" bolts used here. So I think I will try to drill and tap for th...

So what do you think guys ? Would the M20 x 2.5 bolt idea be worth trying ? Or wouldn't there be enough meat left in there. The Deere bolt that should be in there is kind of a shoulder bolt with the shoulder diameter of 0.816" and the thread at the end a 3/4 x 10 tpi. I just stuck a 3/4x10 bolt into...

First two pics are of the side frame hole with stripped threads. As you can see access is through a hole in the dozer frame. What fun ;-) http://i1117.photobucket.com/albums/k598/bozo1236/100_2220.jpg [/URL][/img] http://i1117.photobucket.com/albums/k598/bozo1236/100_2216.jpg [/URL][/img] This is a ...

Hi Mark thanks for the reply. I never thought of that one. If I tried your suggestion and for some reason it didn't work, would there still be enough meat there to do the 3/4 10 helicoil ? Can I find those 20mm bolts in grade 8 or better? If you don't know already the bolts used in these are 7/8 bol...

Hi Labparamour Thanks for the reply. I know, most people think it should be disassembled to do this. They are probably correct but that isn't going to be possible for me right now. If I get the spacer out, there will be more room. Unfortunately the stripped threads are on the hole that goes through ...

JD 450B helicoil stripped side frame to clutch housing holes
Has anyone tried to helicoil stripped out side frame to clutch housing holes with the housing still in the tractor ? 3/4"x10 threads. I'm not sure what material the clutch housing is made of. Cast iron or cast steel ?? real close to the flywheel. Pretty tight in there. Will I have to take off the do...

Mine stopped working too. But is was the meter not the 12v source that failed. I'm not sure but it would have to be a 12vdc source that is turned on by the the ignition switch. I don't know how the hour meter 12v source knows the engine is running. Maybe the same 12v source as the injection pump fue...

Ok thanks smokydiesel. Well I guess if the holes go all the way through then both on that side are broken off inside. I thought one was stripped and one broken but neither one goes all the way through. Still could be partially stripped though. So they must be some kind of structural bolts with big h...
