Villiers MK7 +020" piston rings

As per my other post, I need a set of +020" piston rings for a Villiers MK7/MK10/Acto-Villiers AV3. (50mm bore)

Would be interested in a good used piston and rings as an alternative.

Maybe also try FW Thornton?

May have something in the shed, but will be Thurs/Fri before I can check.

Thanks, I will check them out. I will try Cox & Turner as well.

Had a rummage today and can only find a standard piston & rings

^Thanks for checking. I have sent off a couple of enquiries.

If all else fails I will just have to buy another engine...

Would Mk10 rings fit as they are also 50mm ?

Yes, see my original post...

Had a look in the shed but sadly only have standard size pistons/rings.
Good luck in your hunt.

^thanks for looking. L&S don't have them, FW Thorton can supply at £25 + VAT and carriage. A bit steep but it's my own fault for being a clumsy oaf!

I will try Cox and Turner before ordering.

A seller on a Facebook group has a Villiers C30 thats been refurbed with a 20thou oversize piston. I have no idea if pistons from a C30 will fit a MK7.

Seller is in Nottingham.

The Villiers C30 is 70mm bore, so no it won't fit.

The Villiers 50mm bore stationary engines are - Mk10, Mk7/1, Mk7/RG, Mk2 Midget, Mk 7F, Mk 7F/1, Mk 10/1, Mk10/1HS, Mk10/1RG, Mk410H, and Mk410H-2.

Just noticed that, according to the manuals I have, oversize pistons / rings are listed as +0.015" and +0.030"
Are yours definitely +0.020" ??

Yes, I thought that was strange when I was looking for part numbers. Piston crown is definitely stamped +0.020"

I ordered the rings from FW Thornton today, the chap said +0.020.

Fingers crossed
