I'm not tearing my Brownie Box all the way down as it looks to be in good shape internally. I am however cleaning it up, painting it and replacing the seals and gaskets as the past 60 odd years have taken their toll on them. The input shaft has pressed onto it what I would call a mounting bracket which is used to bolt it to the frame. There is a large bearing on the input shaft which the hanger Trunnion bracket rides on. Curiously, the bracket wont rotate on the shaft which I would think it should. All the shafts turn just fine, but seems curious. The other end of the Brownie Box has two ears integral with the casting from which to support the unit.
The Trunnion hanger one on the input shaft appears to have a rope seal on the back side next to the case proper, on the front it appears to have a large seal that I can't make heads or tails of. I'd like to replace at least the rope seal as I can see its frayed and dried out.
Has anybody ever removed one of these bracket/mounting hangers from the shaft? Do I just need a big puller with the claws on the back of the housing and centered on the input shaft? If I get it off, what's it like getting it back on. Or do I just want to leave well enough alone?

PHOTO 1 PHOTO 2 I don't know what you mean by "rope seal" behind the mounting bracket, I don't understand why there would be a seal in that area. Sure it's not just a scrap of rope or string wedged in there for some reason, leftover from yanking it out in the junkyard years ago? Mine is apparently just metal on metal with no cushion, seal, or anything else tricky. It also does not turn but I expect it will in time, I think it should turn in use as the frame flexes. I've been soaking it in penetrating oil and may end up using some heat to expand the mount some to help with removal.

It does have a grease fitting, and does rotate about the shaft housing. It is a machined fit that doesn't have a lot of play, but will rotate easily and slide fore and aft along the housing, but won't twist hardly any around the housing. I can easily see it rusting into position over time, even with regular greasing the grease never really works its way all the way around the housing and any movement it does is small in operation. | | |
