White Scoutcar Piston rings wanted

[david.carroll01]

The big driver, as I understand it, is not an excess of non-conforming areas between the ring face and the cylinder wall, but rather radial "flutter" of the piston ring under conditions of rapidly changing cylinder pressure. With four bolts per cylinder, the bore distortion will tend to have fourth-order and lower components, to which most compression rings could readily conform. The concern is that cylinder pressure will rise much more rapidly than top groove pressure due to restricted flow between the top land of the piston and top groove. When the pressure acting on the exposed portion of the ring face is sufficiently high compared to the pressure in the groove, the ring can lift off of the cylinder wall and allow large amounts of gas to bypass.


Thanks

Hi Phillip, not sure if this is too late. Have you got the parts you require for your hercules engine yet. If not I do have NOS sets of pistons, Rings, Bearings, Gudgeons, Cams, Oil pumps, Water pumps etc.
Regards
Colin.

Hi Phill - I was just going to suggest Colin Jones until I read the last post. Colin has an absolute bucket load of Stud gear, most of it still in its grease proof wrapping.

BTW - have you located thos instrument panels yet?

Thanks Colin, the oldies Bill and Frank re-assembled the Scoutcar engine while I was away and I'm told it's all good. If however it turns out to be faulty I will certainly be in touch and thanks for the offer.

Bob, I have a few rusty instrument cluster frames etc so better PM me an address and I will get them on their way...

Cheers

Phill
