When stripping down the top end of a Villers, remember that the needle rollers in the little end WILL fall out when you remove the gudgeon pin, and they WILL fall into your crankcase if you dont cover it up......

It then WILL need an experienced (and sympathetic) friend with the correct chainlock, clutch holder, flyweeel puller, and magento removal tool to strip it down so you can get into the crankcase to discover that the last one ISNT in there and has probably fallen on the floor instead.....



Thanks Bruce Austin! above and beyond the call of duty! - I have several pints with your name on them waiting at strubby!

Hi,

The best bet is to get yourself a cut down gudgeon pin the same length as the gap between the two inner edges of the piston.

This will then hold the needles and the small end spacer in place.

Piston changes can then be done in seconds (few minutes if you include those blasted circlips).

Gogz.

Yep, or as we use - a bit of cut down biro thats the same diameter

I bought a machined dummy gudgeon pin from Nametab Engineering. A proper fit!

It only costs a couple of quid.

hi
and how do you get the 22 pins back in
could also do with some tips on honing, spoke to an expert the weekend he said hone the barrel and left it at that
so a little bit confused

put the rollers back in with grease, and of course hold them in place with the tool/dummy small end then fit the pitson and push the tooldummy out with the gudgeon pin

honing - best off taking the barrell to a local engineering/engine recon place and let them do it, will probably only be a couple of quid. ju7st make sur you give them the ammount to hone it by so they dont go mad!

Thanks Justin
going to dive in and give it a go tomorrow. 1st time for everything

You will need 4 thou clearance on the barrel, especially with iron barrels and Thacker pistons.
