Hello its Jeff again,

Liner retainers on diesels they come in pairs , they are machined as such and have to go in the right way round

linner seat

unlike the motor I'm building at the moment they where in all over the place ,

these things go in one way they have a flat face and a tappered face and they fit together ,

lets say we where taking a motor apart and we take out the liner retainers out of No1 pot keep these two rings together with a bit of tape or wire anything will do , anyway you do the same with all the pots marking them as you go, so now when you have done all the bits you need to do put them back in start with the ring without the gap in it you can see the witness mark of the cut away in the block turn the mark 90` degrees from where it sat before , now for the top ring the give away is the dowel slot the hole faces up at you , be careful though some are drilled right through

 if so look at the end of the slot at the face very carefully

 you will see a slight angle on one face , this face goes down in to the block

this is wrong

this is right

see they fit together these rings don't just retain the liners they clean the carbon off the top outer edges of the piston and if they are put in wrong you will see the results on the piston and it clamps the top ring, so there you go be careful ,
