these are the thickest 7/16" stainless i could find. 1/8" thick. can't really tell from the picture, but i believe the washers i have are the same ones you are describing. edges are flat on these.

they were from Zoro tools.https://www.zoro.com/value-brand-washer-716-bolt-18-8-ss-5964-od-pk10-439564/i/G0258447/

is there a link to something thicker if i do indeed need it? hopefully i wont.

Henry, you have been busy and are doing beautiful finish work. The starter and distributor look brand new. Too cold for me to be out in the garage these last couple of days. Thanks for keeping us posted on your work and progress.

(o[]o)

7500 and 5000 watt 220v heaters in the garage for me. but i have to really want to work and get alot done to turn them on....because they also turn my electric meter pretty good too!

i had it up in the 50s in the garage last night with 30 outside. that was with one heater and cycling the run time instead of using the thermostat. those thermostats are worthless honestly.

gonna have to run them pretty good soon so i can paint some more parts. but sunday is supposed to be 70s...so may get the painting in that day.

alright guys I'm batting 1000 on this damn motor. much of which I have refrained from publishing on this forum. but this issue I have to ask of you guys. Parts book is no help.

so I put in 7 pistons no problems. got to the 8th and the oil ring snaps on me when I'm trying to put it on. Kanter sends me another one, no issues there.

I go today to put the rings on the 8th piston, which goes without a hitch, and I notice that the oil ring is loose in its slot. so I pull out one of the old pistons and noticed that the oil ring has two shims and an oil ring expander behind it.

the first set of oil rings from Kanter did not come with expanders. the replacement one did come with an expander, which I asked if I should use and was told no. none of them ever had shims sent.

but now I'm wondering if I should have received shims and expanders for all 8 oil rings.

I really don't want to put this motor together only to fire it up and have big problems! too much money has been spent so far.

the first two images are of the new pistons with the new oil ring and me moving the oil ring up and down in its slot.

the last two show the old piston.

I cannot reuse the old shims because they are standard bore. well technically I can they will just be under a bit.

I have not taken the other 7 pistons back out, but I'm pretty sure they will need shims and expanders and I didn't notice until now on the 8th. I'm worried when I take the oil rings back off they will snap too. this is supposed to be fun....not stressful!

you can also see a ring expander on the second compression ring, which may or may not be needed, but was not sent with the new second rings.

what is the solution guys?

Looking good! On the distributor and starter, did you bead blast? What kind of media did you use, and how much pressure/how big of a compressor did you use?

Good luck on the motor! If you look back at the blog on my 115c (now sold), mine also fought me, but at the end it ran smooth and quiet with no leaks. You're going about it right, you'll get there.

Ken P - LIAR !!! No Leaks? What was that "incident" along Hershey Park Dr?

Did you realize I was watching, right behind you....tow strap on board...

i dunk what i can in purple power and leave for a few days to degrease. then i wash the parts with water. then i let dry and sand blast them.

compressor is 1.5hp 30 gallon 155psi. set at 120 line pressure and used fine metal grit. can't remember the name of it, but i got it at harbor freight or maybe northern tool and it comes in a bucket. its metal, but in the size of grains of sand. leaves a very fine texture to paint on.

i have read just about every page of your 115 blog, actually was going to go back and see what rings you used on your pistons had you got them from Kanter.

had i not caught the issue with the oil rings...i'm afraid i would have worse then an oil leak.

Kanter has sent out the proper oil rings today.

a cheaper and proabably just as effective solution.

Unfortunately HF has neither the glass or steel abrasive. It irks me no end to find something useful and then have to pay outrageous freight. In those two abrasives, to get out here it would be $10 for the glass and 30 for shipping or $50 for steel and 20 for shipping -- and that is assuming either product is something non polluting that is allowed to be shipped here.

do they have Northern tool where you live?
