Chelonian Posted October 21, 2018 Share Posted October 21, 2018 Hi, In a previous thread I posted I mentioned that the phosphor bronze gear on my recently acquired Champion 400 is very worn out. I have since found a possible way to get a replacement gear, and I'm wondering what would be the best way to remove the old gear and install the new one. (I'm obviously not going to try removing it before I have the replacement, but I'm just wondering at this point) I'd like to keep the old gear intact and not break anything, so I'm looking for the gentlest approach possible. I also don't mind spending a lot of time on it either, it that's what it requires. In all the disassembly/restoration videos I've seen, they just leave the gear in, so I'm wondering if anyone here has done it. Thanks! Link to comment Share on other sites More sharing options...
Chelonian Posted October 22, 2018 Author Share Posted October 22, 2018 Judging by how there have been zero responses, I'm thinking not very many people have tried removing the gear. If anyone reading this has, please just let me know what you did to get it out. Is the only way to tap the shaft with a hammer? Would it be helpful to use a penetrating fluid? If so, what kind? Thanks! Link to comment Share on other sites More sharing options...

A 50/50 mix of auto trans fluid & acetone does wonders for freeing up frozen parts. Have you read this thread & watched the video? https://www.iforgeiron.com/topic/54691-champion-400-blower/ Link to comment Share on other sites More sharing options...
Chelonian Posted October 23, 2018 Author Share Posted October 23, 2018 Yes, I have watched that whole video series, but he never actually took the bronze gear out. The bronze gear is also pretty much the only part I haven't taken out for cleaning on the blower. I'll try that penetrating fluid idea. Does it evaporate really fast, or does the trans fluid slow that down? Thanks! Link to comment Share on other sites More sharing options...

Chelonian Posted October 28, 2018 Author Share Posted October 28, 2018 Unfortunately, it appears my possible source for a replacement gear won't work. He simply never responded to my email. Link to comment Share on other sites More sharing options...
anvil Posted October 29, 2018 Share Posted October 29, 2018 He is not doing much smithing anymore. I anxiously await his return. And, no doubt, parts are hard to find. Link to comment Share on other sites More sharing options...
