[QUO TE=msrfan;651141]Afterbuwing the valves and seats through my optivisor, they could use a bit of finer lapping. So I broke out my Siuox lapping tool, made an adapter to fit the slot in the valve heads and finished the job.




A little guide lubricant the valves are in, i used my homemade spring compressor.





The engine is in my assembly stand and I was about to press the new needle bearing in the side cover when I thought I better see if the owner wants to buff it out and polish it. He has the equipment and it is a little beat up.

You do excellent work as always Dale.I'd really would like to see the side cover when done (Polished)
Check your trunnion for excess play,might need to press in a bushing.

The ring end gaps were right at the limit, so I found some NOS Whizzer .030 rings in my stash of parts. Hate for it to smoke after all the work I did. While waiting on my customer to polish the side cover, I put it on long enough to set the crank end play and valve clearances. Ray brought me a gasket set so I could torque the head on. Thanks Ray. I also installed the crank seal and slipped the carb and exhaust elbow on to see how it looks. Moving pretty slow on this build, but I keep busy on other projects. My buddy Joe wants me to get his Simplex running when I finish the Whizzer. I never worked on a Simplex, so it should be a real learning experience.

Thanks for the 3rd millennium, clutch parts! And my cool AM/FM horn radio
It's coming along nicely Dale, you won't be long now.

I got the side cover back from the owner all polished and it looks great. His was too deeply scratched, so I donated one of my spares. Now I need to double check the crank end play and finish the assembly. A little clean up and it gets installed onto the bike.

Thanks Zip. Starting to clean up the bike some. It's pretty disgusting. Even sitting in storage 5 miles from the ocean corrodes and rusts metals.

Tried some rubber dressing on the pedal blocks after cleaning.







Still pink but presentable. And now the pedals spin nicely.





Lots of rust where the pedal cranks were bent for engine clearance.



The race that retains the sprocket was worn heavily. Luckily I had a nice replacement. Taiwan cranks on a vintage Schwinn. The original builder cut more than a few corners.





A few minutes with a high speed Scotch Brite pad and some clearcoat made the cranks look a lot better.

I polished the chrome on the bars and gooseneck and replaced the rusty washers with AN stainless on the pinch and wedge bolts. Took the front wheel off to clean it up and find out why the Schwinn front drum brake had no lever or cable.





It was full of rust on the inside and the lining is worn down to the rivets. I cleaned it up, greased the bearings and put it back together for now.




Removing the tank revealed the front mount missing and some kind of glue or epoxy on the underside. The owner has an embossed tank to put on it so I'll just use this one for test riding.





Tomorrow I'll clean the rear wheel and motor mounting area. Should go pretty quick now that the engine is all together.
