hello all i need a bit of help. alltho im new to passion ford my zetec turbo engine is about 80% finished bar one of the biggest parts of the engine the con rods im useing c20let pistons and as most of you no the small end needs macheening out to take the c20let pins.

can some one please give me some information of a good company who will carry out the work?

 

any good machine shop will be able to help you mate! its not a hard machining job

 

dident think it was ive taken them to a shop the next road from me and he dident seem to keen. also probaly me being a bit stupid but the let rods are free floting and the zetecs are when standard pressfitted. will it be ok to convert them to fully floting? ive never heard of any won fitting a small end bairing?

 

I doubt you're going to be able to fit a bearing into a standard rod for a 21mm pin!

 

thats wot i thort but how does every one else do it with the standard rods?

 

yopu use the circlips on them and drill a 5mm hole in the top and counter sink it to allow oil flow then balance them . (this was told to me by ian howell and works in mine

 

thanks paul how do i keep my cps attached to my throttle body????

heard you use cable tyes???

 

sounds odd... you'd be better off making the vauxhall pin an interference fit in the zetec rod there's no chance of it wearing that way

 

but the let pistons are fully floating? do you think this will matter? i see it as it was made this way for a reason (even tho they are in the wrong engine)

 

Found the button then clarke

Ian Howell knows his stuff generally, and to be fair Paul's had it done!

 

it dosent matter... the let rods have a bronze bush in them because they are fully floating, the zetec rods have a press fit pin (into the rod) and no bronze bush. the pistons themselves float on the pin in either setup.

i'm not just talking about what i've heard on the internet here... i'm a machinist and i KNOW which way i'd do it.

 

cps goes in the block you fool , you mean tps and being in the rugby club car park it was my only option to replace the screw with the cable tie, replaced it today though with a new screw

 

im using the vauxhall pistons but was advised by ian howell the oil flow wouldnt be good enough and to drill the oil feed holes in them

 

i'll agree if you mean drilling holes in the piston, but not in the rod?

 

ok now im confused realy confused ive got my rods and pistons wot should i do (paul wot you like with sand paper and a drill )

 

You get the pistons fitted to the rods.. interference fit as above.. you also need to machine a bit from the skirt to clear the oil squirters.. and then balance them

 

would you carry out the work or no who would?

 

No, i'm not a machinist!

 

speak to ian howeel at area six mate, he's a top blike and will sort you out

 

I had mine done for LET pistons, havent drilled a hole in them for oil though

 

not saying its not ok as i dont personally know, ian howell and gosnays engineering both advised me to do it as the zetec piston is a sweat fitted gudgen pin as where the c20let is floating so requires good oil flow once modified
