Default Re: H Whizzer on Schwinn-Older Restoration

[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.
