More miscellaneous cleaning and sub-assembly.

Cleaned and polished the brake pedal and the clamp that goes on the opposite end of the brake shaft. Cleaned the rubber cups and washers that go on the shaft as well. Slipped everything together.




Cleaned the starter button and installed it into the bracket.


Cleaned all of the pieces to the steering damper assembly. Sprayed the knob with S100 Engine Brightener to make it black again. Replaced the steering damper with a new one. 


Working on the swingarm next.


New swingarm pivot bearings and seals.



New carrier bearing...


...u-joint...

...boot and clamp. 


All finished and ready to be installed.


Cleaned the "mudguards". Haven't polished the stainless any, not sure I'll need to. 


These knobs aren't original, but do the job and are 1/3rd the cost of the o.e. type reproductions. 


Axles. The front one cleaned up very well, the rear one - not so much. 


It really needs to be rechromed.


The washers look good, the nuts will be replaced with stainless steel ones. 


Disassembled the rear shocks. The dampers themselves are in good condition - no leaks and nice damping. The retainers and adjusters will clean up well, the springs? I'm soaking them in EvapoRust to see if that makes any difference. 


I've had a pair of NOS springs for years and hoped that maybe they would fit. Close but no cigar.  :sad: Not sure what the springs fit.

After soaking overnight in the EvapoRust, all of the rust is gone and the springs look 100% better!




Stripped the paint from the dampers.




Cleaned the adjusters and retainers.




Quickie polish has them looking better.




Painted the dampers.




To finish out the evening, I disassembled and cleaned the taillight. The bracket needs to be painted, but the taillight is ready to go back together.

Rod bearings are showing some wear, but not as much as I expected, really.

Rear main wear.

Crankshaft looks better than expected, but again, it will need to be measured carefully.

Front main bearing wear.

Charlie:  Maybe I missed it, but how did the rod and main bearings measure out? Did you replace them (sorry if that's a dumb question)? I have only taken a similar engine apart once, and the photos you showed looked more alarming to me than you indicated. How much of the wear do you think could be attributed to the chrome flaking off the cylinders?

Main bearings had very minimal wear (consistent with the mileage) and were reused, rod bearings were replaced. Most of what you see in the photos was superficial or was made worse looking by the camera flash. There was no evidence of any embedded chrome flakes.

It's been a while since I've posted an update.

Transmission case back from being cleaned.



Case and rear cover heated, chilled bearings installed.



Starting assembly.

 
Assembled.




Mated to the engine.



Assembling the lower frame rails and centerstand to the engine and trans.


Up on it's "feet" again.


Going to need a helper at this point


Working on the rear drive. Completely disassembled, heating the case in the oven so the outer race of the needle bearing will drop out.


Most of the cleaned internal bits. Seal surfaces of the carrier have been polished.


The outer race has been spinning in the case - not much, but any is too much.



Case ready to go off for media blasting.


Friends Travis and Martin helped me lower the upper frame onto the lower assembly.


Hooked the plug wires to the coils.


Installed the ignition switch.


Peeled the hard, old tires off of the rims.


The front one is pretty nasty under the rim strip.


The rear one has one bent spoke. How did that happen and how did only one get bent? Darned if I know.


Pretty good kink in it once removed.


Replaced with a good used one from my stash.


Both wheels completely stripped now.


Rear one wasn't quite as nasty under the rim strip.

Looking good Charlie,

how does one spoke get bent so bad and the rest remain OK?, wheels cleaned up good.

Still some photos missing. Gotta' find and add them. Found 'em. Added.

Good question and one I've been asking myself. Wheels still need to be cleaned yet. Hubs are corroded, rims are dirty and dull.

Working on the forks. Completely disassembled, sliders and top plugs cleaned.


Someone in the past has been none too careful when removing the seals from the right slider. Lots of gouges. May need to apply a little sealer to prevent leakage.




Both fork tubes have rust spots, on the left one they're above the seal travel, but on the right one the seal would be going right over it. Plus, due to an almost complete lack of oil in the right fork, the chrome is worn through on the tube.




The dampers still work well and aren't leaking, the springs are still within length spec., so both will be reused. Everything cleaned and reassembled, ready to go together once the new tubes arrive.


Sliders polished, new seals and hardware. 


Assessing condition of the wiring. The fuse block has seen better days. You can see it got hot enough to melt the plastic in the top right corner.



Hot enough to melt the clear plastic cover even. I'll be sourcing a replacement fuse block.

Forgetting to undo the chain you locked the bike with would do that..

The new forks tubes and dust wipers arrived today, so I assembled the forks and started reassembling the front end.











Now, if the chrome would just return from St. Louis Plating...  :sad:

Installed the plug caps...


...and breather hose.


The lower end of the hose fits through this bracket. 


Slipped the shift linkage arm onto the transmission. This linkage is worn and sloppy, I'll be using ball joint rod ends. 


Preparing to install the swingarm. Boot clamped into place and rolled up over itself, splines greased.   


Swingarm installed.



Rear drive mounted up.



Cleaned up the rear brake light switch. It was quite rusty, but cleaned up pretty well. It even works! Amazing. 


Painted the bracket, formed the spring back into (almost) the original shape and shot it with a little silver paint.


Test fitting the battery tray.


To end the evening, working on how best to route the tach cable.


Next day. Bolted down the battery tray with brake switch in position. 


New rubber tray and straps.


Installed the inner rear fender.

Beautiful work Charlie - thanks for the details.   :thumb:

BTW how did you make sure the new bearing would not spin in the rear drive casing again?

Since there was absolutely nothing wrong with the original bearing, it was reused. A light application of Loctite 680 makes sure it won't spin in the case again.

It's been a while...

Sent a "test batch" of bits that needed rechromed to a company that I'd never used before on Dec. 31st. They received the parcel on Jan. 7th and told me it would be 8 weeks. Okay, I know the Winter is the busy season for chromers, so no problem. At 10 weeks I checked the status and was told "soon", 14 weeks - same thing. By April I was getting worried that they'd lost my stuff. "April 19th" was the answer. It was finally done and shipped on Tuesday and arrived today.  :shocked: Okay job, reasonably priced. I sure do miss Brown's.




I've been slacking too, haven't gotten much done on the project since. Feb. Other projects have been "front burner" and this was relegated to "back burner" status. I did disassemble the wheels and send the hubs off for media blasting.




The brake backing plates were stripped and they too were media blasted.

Started on the carburetors today, doing the "lazy man's" way of cleaning the big parts. They're soaking in Pine-Sol while I do other things. The shop smells very nice right now. All of the small parts will go into my ultrasonic cleaner.

Major parts cleaned.


Almost finished.


Done.


Need different "velocity stacks" for the filter the customer chose.


Front fender mounted. 


Foot controls, foot rests and linkage installed.




The original brake switch spring broke, so I found this VW brake spring in my stash of "junk". With a little modification, it works perfectly.


Test fitting the axle.



Installed the springs on the dampers, applied new Koni decals.


Brake side lever assembly nearly finished. The lever needs to be polished yet.


The clutch lever is bent even worse than the brake lever was. Hopefully I can straighten it without it breaking.


The pivot screw is juuust a little worn.  :wink: I'll need to find another.

Brake lever pivot only a little worn? Yeah, right!  :grin:

Better replace the pivot bushing also.

The lever shouldn't be a problem. I've straightened them worse than that. Clamp in a vise, heat the bend with a propane torch while putting pressure on the end of the lever, when it starts moving you've got it. Don't use a chunk of wood to push it with, the heat makes the wood slippery and when it slides off, your hand rubbing across the hot aluminum will be left with an ugly scar.

The bushing in the lever is almost completely unworn, oddly enough.

In the photos I took of the parts before I sent them to be rechromed, the pivot screw wasn't worn like that. I wondered why I would have sent a worn screw to be rechromed, turns out I didn't. Looking at it closely shows that it was "worn" by a grinder/sander/polisher.  :angry:

Thanks to Warren at Hagerstown Auto Interiors, the seat looks like new.  :thumb:




Amazingly enough, the second batch of chrome finally came back - it "only" took them three months this time.  :sad:




Back to where I left off.




Moving on. Installed the crashbars...




...and headpipes with new exhaust nuts and "P" clamps.






Test fitting the crossover.
