67 BSA Victor - just got my latest Project

WELL!
I must say that with all of the GREAT builds being posted lately.....
grandpauls Triton
worntorns Vincent
and
Pelicans Manx
I am feeling a wee bit "inadequate" here with my poor little BSA 441 backyard build.

But, onward!
I'm still cleaning as I go, Remove a part, Clean, bag and tag it.
So far I have been through the transmission, oil pump and clutch. All are ready to
go back in when the time comes.

So far there are have been only 2 issues that I have found, a tooth busted off of 4th. gear
and what looks like maybe the crank bearing rubbing on the case (see pics).
Other than all new bearings, bushings and seals, there doesn't look to be a whole lot of work
that is going to need done before I can start to re assemble the engine.

A couple of the latest pics:

She'll be a thing of beauty Mark.
That last photo looks like a "Spare parts wall Display" from the Sixties.
Will you go with the original Tank, or opt for an alloy B50 type / early CCM.
Take care when the Flywheels go back together.
Not sure how similar the 441 is to the B50 / early CCM barrel, but,....
There was a Weslake, 4 valve conversion, for the early Clews Comp Machinery. (late 75, early 76, I think from memory).,
avaliable for 1 year approx, untill Clews built his own.
Any way, she'll go alright, plenty fast enough for the suspension.
A Mk.11 Amal or Mikuni, in 32mm is a notable asset, unless you never fall off.
Then of course there's total loss ignition, for wieght saving. etc.etc.
Sounds like great fun to me.

How did you clean the alloy castings?

Mark - well, you've achieved a great finish with inexpensive products and some elbow grease and I think it looks better than if the castings had been bead blasted. Looking forward to the rest of the build. Carry on!

I recently purchased a HF benchtop blast cabinet and 35# of their medium baking soda media. I originally purchased it to do some decorative wall lights for a customer, but on a whim I threw my cases in there, WOW. I made sure they were as clean and degreased as I could get them. The results were fantastic. The cases look just like they were made. The BS media only removes paint and dirt, no base material is disturbed. I am going to use this a lot more. I did my engine and transmission cases on the combat. The best part is after you are done blasting a little water completly removes any traces. No nasty grit to destroy bearings.

I would love to use soda blasting. It is a much gentler method of cleaning.

Well, I got the crankshaft assembly back together today. The conrod is now spinning nicely
with no longer any up and down slop.

It really wasn't too tough once I figured it out. I only had to take it apart 4 times to get it lined up.

I trued it up (rigged up a quick jig) and the runout is right on.
How do you guys on the other side of the pond say it? ........It's the Mutts Nuts!

One thing that really helped me get it lined up so quickly is that I scribed a couple of lines on the
flywheels before I separated them and used them as index marks when reassembling.

Image

I also relieved the inside of the bearings so now I have a tight sliding fit on the crank shafts.
I did this for the purpose of assembling, measuring the endplay, centering the rod, disassembling and shimming.
I am making this bike a full roller bottom end ala 850 commando.

Image

:mrgreen:

The outer roller bearing races are in the freezer right now, I'll install them in the cases tomorrow. Then after measuring,
I know that I won't have the right shims to attain the .003 endplay so I'll have to order some and
wait to receive them before proceeding.

Looks like you've done a thorough job, Mark. I was not familiar with these engines until you started this thread. Am I right that you converted the bottom end to rollers from ball bearing mains? Or was it a ball on one side, roller on the other? Is the timing side of the crank pulled up tight against a register or is the end float controlled solely by shimming? Do you have a figure for the side clearance of the con rod to flywheels? What type of big end bearing do you have? Is it an alloy cage with loose needle rollers or a steel cage?
