You know, I haven't opened it up to take a look at it yet. I'll do that and report back. Probably couldn't hurt to replace the packing anyway.

Got it running this weekend! New headlight, fork dust boots, fuel petcock and lines, and air filter. Rebuilt the carb, serviced the front forks, cleaned and derusted the fuel tank, cleaned the frame, put the original seat back on, changed the oil, and repaired the broken muffler mount. The headlight cage is missing, my dad added an extra chamber to the muffler, and she has some battle scars. I rode it back in high school and dad used it for hunting and irrigating. I might ride it off road now and again but it's satisfying to hear it run again. Thanks for the help with the muffler mount.

Just thought I'd post the repaired frame/bracket. Again, thanks for the reference pics and advice. Sorry, my welding sucks. It was hard for me to see what I was doing up under the frame member.

Hmmm.. well, I did make one of those out of 2mm sheet metal. Yeah, I measured the gauge before choosing my stock, that bracket steel is only 2mm thick. I cold formed it with a good ol' fashioned hammer, dolly, and anvil. No, it's not exactly like the factory down to the mm but a tad larger. You're right in that it was tough to do but it's close enough to the factory piece to get me by. I still have the dog-bone piece but the rubber was removed years ago so I made a new rubber insert and bolted it back together with a 10mm bolt and locking nut. I'll post a pic of the rig after I weld it onto the frame just so's you can have a good laugh. Thanks for the help guys!

Thanks much for your great reference photos. Much appreciated!

Hello. Thanks for your help. I understand the complex shape of the bracket (rolled edge for strength) and that's okay. Even with a tracing I can allow for additional "meat" to the edge to allow for rolling the edge up (I'm very adept at fabricating stuff like this). What would be helpful is the overall dimensions and the placement of the mounting hole. Otherwise, I would very much appreciate a simple photo as it would at least give me a place to start as the broken section of the bracket has been missing now for several decades. Thank you for any help you may be willing to provide. - Alex O.

Hello. I'm a new member here and am working on my dad's 76 TY175. He had broken the frame muffler mount many many years ago and had just bailing wired the muffler up to the frame and now that I'm working on getting it running again, I want to fabricate a new muffler mounting bracket that is welded to the bottom of the rear-right seat frame tube. Would it be possible for somebody to draw or trace that small triangular bracket and email it to me so I can reproduce it (somewhat) and weld it to the frame? Thanks for any help or references provided.

Hi all. I'm a new member from the Portland, OR area. I've recently inherited a 1976 Yamaha TY175 from my dad. I rode this bike back in the 80s when I was a teenager and dad used it for years as an "irrigation bike". He's recently turned it over to me and I hauled it to Oregon and am working on getting it running again. It's in pretty good shape and not too far from running again. It really just needs some minor aesthetic work and fuel/carb cleanup. I have some questions about a muffler mount that I want to repair so I'll ask in the Yamaha forum section. Thanks!
