Tracked down a new (new stock!
) Mahle piston with the proper rings..
for my old 1.8 CF1 and so I had a look at fitting it to my con-rod.
I fitted one circlip into the bare piston fairly easily by stuffing it into the piston hole open-ends first, and then rotating it round until it dropped into the clip grooves.. but I can't do the same on the other side, since now the piston is on the con-rod and the gudgeon pin is in there.
Is there a special tool (pliers?) to compress the circlip in a uniform manner so that I can drop it into the piston hole... or is it just a regular pair of pliers and try not to deform it when I squeezes it?
I haven't had a determined go.. just tried it with regular pliers but the circlip kept pinging out across the driveway and I almost lost it...
I can't imagine that's how they do it in the factory... There must be a tool or maybe I'm missing out on some better/crafty old technique or something??
Edit: I should add, the gudgen pin clip is not a regular flat section "C-clip" circlip - the type with "ears".. It is essentially just a round-section bit of plain steel .. like "wire".
If it comes to it, could I use a flat C-clip circlip on the end of a gudgeon pin? Why is the standard circlip round-section, rather using than a flat-section... and does it matter)? I'd prefer to use the factory style (round) circlip I think..
