Can someone give me example piston-bore and crankshaft-piston tolerances for any Wankel engine. Thanks Regards Damiano RVF Dyno-Tech -- ... Jeszcze lepsza...
You draw a picture or sketch of a Wankel engine and draw arrows where you think these tolerances ought to be, please. Then we can answer your question. Or...
Is this a question like "where can I locate a .000 feeler gauge " ?? ... From: "Ernest Buckler" <ebuckler@...> To: <mc-engine@yahoogroups.com> Sent:...
It shouldn't be too hard to fathom out. Take a look at http://travel.howstuffworks.com/rotary-engine.htm The crank is easy. It's effectively a plain bearing...
... ***I haven`t seen plain bearing there but central ring gear http://www.keveney.com/Wankel.html and I realize that it has to be made with tight tolerances...
... Would have to be pretty damn close to be tighter than piston engine clearances, say piston clearance of .002", bearing clearances of .0015. WAY tighter...

I am machining a 69.5 mm bore piston from a forged blank for my alky 250cc racing pre-war Velocette.......getting ready for the big race at Phillip Island at...
... Sorry, it's just not so. Pumpers always have more skirt clearance. For ex, most all the Japanese AC bikes ran .001-.0015" skirt clearance. Most pumpers...

I think I already attempted to have this conversation with you..... perhaps you overlooked it and not simply ignoring me. Feel free to tell me to piss off if...
Greg- I looked into this a while back and, if I remember correctly, was told by a piston manufacturer that TFE buttons only work in very short duration...

Tom, I'm not sure what qualifies as very short duration. I've used teflon wrist pin buttons on a couple of Norton 920 cc road race engines, and they held up...

That's right - Honda CB750 had a big one, with rubber seat and I don't think they leaked. Did he mean he doesn't like cutoff valves on the suction side? Only ...
hi guys. with all this recent talk of oil pumps, you've reminded me i need a 12v electric oil pump for scavenging oil away from the turbosystem on my gsxr....
Subject: electric oil pumps....... ... Now you've got me thinking; how does the turbo on my CX500TC scavenge? As far as I know the drain line simply returns...

Greg, I wouldn't check the burn characteristics of PTFE Teflon as before and certainly after it burns it gives off Phosgene gas which is terribly toxic....
