completely round piston circlip extraction/fitting

[Supereibar]

Stupid question but I cannot come up with a sensible answer. Can anyone explain how do they fit them? I cannot thing of a propper way without some special kind of plier?

There are lots of different types of circlips used what type are you having problems with ?I've just recently fitted an Mb type piston and their circlips don't have eyelets in so you need to use a very tiny electrical screwdriver to ease them in but be careful not to damage the piston in the process .
Most pistons have a tiny cut out inside where the gudgeon goes so you can get the clip (normally) but I always fit new circlips as its never worth taking a chance .

the ones I mean are the kind that are made of a single wire without any bends. Like a full circle with a cut in the middle. "C" shaped.

Thin screwdriver or pic tool then , that's what I use

Icklelittle mini drill an grind a small hollow in yer piston if it dont got one an yer can get y circlip out,
muppet,

[RICSPEED]

there should be a small cut out next to clip .. as said small screwdriver or pic ..but put a finger over the hole as you do cos the clips can fly and lost forever

You are fitting right Jaime?

Get a clear plastic bag and cover the piston area with this (to catch the circlip when it pings out!!); fit piston to con rod etc; ease one end of the "C" into the grove, and with a small pair of pliers, lift the other end into the groove as well at the same time pushing the "C" closed; make sure all is within the groove and away you go

But Chris, there is no way of fitting the damm circlip without damaging the piston surface... The Bl@@dy thing does not stay in place!!

[bristolmod]

you have to compress it slightly to allow it to slip into the groove- get one end in and using some very thin pliers, push the other end "against" the resistance and voila!

They are tricky and tight - once they're in correctly they won't pop out like the cheaper type and do some damage. I had them with my Muggy kit about 6 years back and I had the same problem.

Do you want me to pop round and have a look??

Its no good giving up and getting stroppy Jaime! What if Sir Francis Drake had that attitude? we'd all be speaking Spanish now...................!!

Yes they can be a bit tricky, but one thing I`ve learnt is that if you have taken them out for some reason don`t re-fit them, fit new ones, I had one pop out and it wrecked the piston and TS1 barrel.
This was one that had been taken out and re-fitted, when a d/side oilseal was replaced.
