Cylinder and head

The motor is all closed up. We finally put the new cylinder jugs and pistons onto the main motor assembly. I had to machine the jugs to fit a oil bung but other than that it fit like a charm. We also ground the valve ring in the head and we are ready to reassemble the springs. I think it looks pretty good. Next up carburators.

Solidworks moving right along

Primary Side complete.

After almost a year and a half, I finally have the bottom end back together. This weekend I put the finishing touches on the Primary side of the motor. The hard part was finding the clutch push rod. For some reason during dismantling of the motor, I put the push rod in a draw in my tool box. Needless to say I don't remember doing it, but just by luck I found it. The good thing is I cleaned off my work bench in the process.

Now that the bottom end is complete I mounted the motor in the frame. I thought this might be the safest place for it. It looks good and the bike is getting closer to being road worthy.

I also found out this week that my cylinder barrels are too pitted for boring. My guy from Integrity Auto suggested I get a new barrel. Thanks to Ebay, there is a rebuild .030 over barrel and new pistons on its way. Turns out it was way cheaper than boring my cylinder and buying new pistons.

great article

I found this article really interesting and though that I should share.

Solidworks almost finished

I have found some time to work on the solidworks model. I am almost finished with the motor and the frame is finished. I think it looks pretty cool.

Transmission Rebuilt

My buddy Paul got me a hook up on some Gardener-Westcott cover bolts for the motor. Which look really nice. Thank you very much Paul.

I have also rebuilt the Transmission. It was actually fairly simple and surprisingly it shifts through all the gears on the first assembly.

On to the Primary side.

Kibblewhite

After many hours of searching and comparing, I have decided on valves. I went with the Kibblewhite Black Diamond. I have been told by several people that they are the best. So with that advice I jumped. If all goes as planned she should be a clean running machine.

Progress report

It was pretty nice this weekend, so I thought was time to take the Triumph off it's stand and get a picture or two of it in the day light and on its wheels. As you can see most of the frame is put back together. I have my buddy Paul working on a front tire for me, but I am still up in the air for a seat and oil tank.

On the motor, I have the timing side and transmission rebuild. I have ordered valves from Kibblewhite Precision Machining Inc, and sometime soon I am going to order some pistons.

Cheers,

New transmission

One step closer to a roller

I finally found all the parts I needed to rebuild the front forks. This might have been the hardest part so far of the rebuild. The original forks that sat outside for 25 years were rusted to nothing. The only thing I could use off of them were the Dust Excluder Sleeve Nut. I have bought 3 set of forks off of ebay and none of them worked. Just a warning people will say anything to sell there stuff on ebay. I finally found a local guy who sold me a 68 triumph front fork and all is good.

I used the internal parts from the 68 forks and bought some new tubes from my Racing Norton's guy. Mike gave me the bottom members and finally we are assembled. I also bought some new handle bars.

next up the front wheel.

68 bonneville timing gears

Seat mock up

I have been working on the seat and think I have found the way I would like the bike to look. You have to use a little imagination but I think this is right there.

Timing side assembled

The cases are now one

Uncle Hank

The Triumph bug is going around. My buddy Hank is building a Triumph Chopper. Awesome!

Footrest

One night I went through and found all the hardware for the footrests and brakes. The cool thing was I found everything. The bad is that most of the parts are really rusty and both footrests are bent.

Whats cookin?

Friday night the wife went out with the ladies and I cooked up some Triumph crank shaft bearings.
It was almost too easy. It's freezing outside, so I put the bearing on the back porch for a few hours. Then I fired up the oven to 350 (I chose 350 because my mother cooks everything at 350). I cooked the primary side first for 20 mins. I pulled the case out of the oven and dropped the frozen race in. I was ready to have to force it into place but I was able to push it in with my fingers. A few minutes later the race was not moving and in its proper place. I did the same thing for the timing side and the transmition bearing.
Next up reassembling the cases.
