h there ppl i posted a thread abit ago on where i could get me engine rebuilt an i thought id have a bash myself as it was cheaper and as iv heard its dead easy to do. right where i am at the mo .iv got the engine stripped down to a bare block im just stressin on what size pistons i need after i get it bored or re honed .and if it needs std main and big end bearings or if i need oversize bearings i think the engine has never had a rebuild be4 i think its all std the bearings all seem to still have there original bearing stamps on them thats why im asumeing there std but i dont wana take my own judgement .any help welcome or critisisum psml

it will end in tears if you need to ask these questions imo.

the yb will bite you if you get anything wrong bigtime....

in your position id get a pro to build her pal

bud-weis

Bigger bearings will have .25 or .50 markings in them. When reboring go to the smallest size needed, ideally .25

It's easy enough to do, but some knowledge would be useful to avoid heartache

its a costly mistake to rebuild a yb with no experience
if your not sure about pistons and bearing sizes then i'd advise leaving it to an expert
if you are sureyou want to try it yourself then take every part to an engineer to get properly measured and checked, it might cost you a couple quid for this but at least then it'll have the correct parts,
dont try rush the build, take twice as long as you think it should take and tripple check everything,
imo a yb is a heavy stressed engine and so not a good jigsaw puzzle to start playing with as everything needs to be perfect or it will go horibly wrong
anyhow i do admire your courage for trying but just be very careful and seek expert advice at every point

i just wanted to save a bit more cash really .i just want to learn really id like to now more about the engine .i dont mind if it all goes tits up at least i had a go really i luv me cars an just wana now more im always palyin wid engines but im a welder by trade .i have done bearings change on me old 4x4 saph cossy be4 but not pistons .i changed cambelts an seals to but not a full build . i now its sad but i sit on me breaks at work an just read me 2wd cossy manual just to get a bit more info .as my engine is all in bits if i took it to a builder would they turn me away an not want to now or would they charge me more as its all in bits rather than a full built engine .and what sort of price would i be looking at for a std rebuild thanks ppl for ya replys

Ive assembled a couple of engines and its not that hard with a manual etc. Trying to work out sizes and bores etc are not so easy I get help from a local machining shop/engine builder.

id love to rebuild an engine.be great satisfaction if you managed to get some good figures out your own work.

any engineer will have a look/measure for you
if its just a basic standard build then by all means have a go
they are old engines and so very basic realy
just dont go trying to go for much more than standard power or this will get harder
bit more involved when you got porting, mod'd valve seats, cams to time/dial etc
but as i say take more time than realy needed and triple check everything
and lub everything up proberly, i.e pistons, cam journals, big and small ends, mains etc
