1976 T140 Runner (not Restoration)

[Martyman]

Hi I'm Marty from Markham Ontario. I've have mainly Japanese bikes from a Honda XR75. Hodaka Ace, CB350, Honda elite scooter, Suzi 550...now a BMWK100 and my latest aquisition a 1976 Triumph 750. I really looked long and hard for a british bike to buy mainly because my dad had BSA's when I was a kid and I remember how much work he put into them and how cool the ended up looking and sounding compared to his Japanese bikes.

I picked this up for a fair price, it looks great from a distance and up close it really needed a lot of parts replaced.

I got it running in a week and rode it around the block the next week. brake's were rotted garbage and and have been replaced with new front aftermarket controls and the rear a new mastercylinder, also new braided lines for front and back. Cleaned and coated the tank and rebuilt both carburetors and have spent more than a week replacing and truing the rear wheel with new spokes. so far the only thing that has thrown a wrench in the build has been trying to figure out how the rear hub goes back together. I've enquired to so many people online and been sent the diagram that does not match my hub so I've either go a hub from a different year or the diagram is wrong. I'm waiting for my back ordered rear tire and hoping that I can get the answer to my hub mystery before that and be able to give the bike a proper run.

Welcome from another Maritimer.
Sounds like fun fixing that older Bonnie.
Hope you get the wheel issues sorted so you can get out and ride.

Welcome to the forum! Glad you got your wheel problem sorted out, but please tell us what the problem was. It could help others in the future.

Welcome to TT, I also have a 76 Bonnie. Did you get the spacer problem sorted out?

This last week has been so busy with my work schedule I will eventually post a video so someone with a 76 will be able to find it and figure out how the hub goes together. Here is a quick explanation of how I figured how how it goes together.

What I've learned about the 1976 T140 Rear hub diagram that its confusing to look at. #11 I'm still not sure why that center tube has a taper to it (mine does not any any that I've seen being sold do not), would make more sense if it did because the two grease retainers #30 (they are grease retainers not "dust rings" go on the inside of the bearing like the diagram. Why one of them goes on the inside of the sprocket side bearing with nothing to hold it there is still not clear to me but when it is all put together everything lines up. I have a pair of mint condition made in canada unsealed bearings that I as going to throw away until I did ordered a pair of new sealed bearings only to find out later I was sent the wrong ones (and made in China) so I sent them back. I've decided to use the made in Canada ones and with those I will need to use both the grease retainers, if you do put in sealed bearings I would think that you will need use the ring as a spacer on the Speedo drive side for spacing. I was very confused also in my search for an answer because the only photo's I could find of the grease retainer in a hub were ones shown on the outside bearing before the speedo drive locking ring and that could be because it was being used as a spacer?
