advice on splitting cases

ok so its my first time doing this and i was just wondering what you guys use to do this because i dont want to mess up the engine cases

ive taken absolupetly evrything off the cases other then bearings piston and crank
ive had a look at haynes manual but its advice is to buy a tool for each side of the case is this needed?
thanks james

 

i did this for the first time last week aswell anyway...

lol dno if this is right (lol) but when i got everything except crank and bearings of mine, we just used a rubber mallet and smacked one side of the crank and it split. then we smacked the crank out the otherside. (assuming you undid the bolts and your replacing the crank cause it can fuck up the threads... )

im pretty sure you can get a bearing pulling tool thing to get thebearngs out...lol

Oh and dont jam a screw driver or owt in between em to lever them apart...or you'll probably end up fucking up the seal.

 

he realised that he dont need to spilt the cases lol .for the record you dont wanna be smacking anything if keeping the crank

 

lol you used my crank as a hammer

which is a bit of a bastard..cause one sides got fucked threads
and i might have been able to sell (or keep) it :/

yeah i just wanted to answer a question xD

 

yh coz ur getting a new crank .there worth about 40 pence second had on 20k m8 wudda jus sat in ya room doin jack .

 

lmao so u used it as a hammer oh and btw mate cases are gone and the guy sold me a crank out of an engine thats dun under 5k km with standard engine for fiver off the price of the cases in the end he bought the cases for 60 quid 4g of skunk (25-30quids worththe way peolpe seel it now) and the crank whih is now in freezer

 

yeah buttt most people have 50 top ends laying around and i sold that

anyway stop chatting on here lol we spam so much. im on msn.

unles your trying to get post count up

 

nice one lol

 

u decided not to go for the bgm then i see lol ?

 

if you want it done properly, buy the tool and get reading, not worth bodging it, i learnt the hard way. cases aint cheap and its hassle swapping everything over just after youve built it all up and got ur hopes up for that perfect 'first run vid' on youtube, only to realise your bikes fucked.

 

:rofl:

 

lol its all done and sorted guy came and collected old cases earlier

btw did it with a hairdryer

 

llol may aswell not used a hairdryer, cant see it doing much tbh

 

He knows this.

 

not all he knows :rofl:

 

...what else do i know? and you say hair dryer dont work but its like weed in small amounts yea dus nuthin but if u smoke a half o/an o then you start thinkin hmm i think im high and my cases wer thinkin after 1 min of hair drying goodness hmm we all thight n shit nuthins pullin us apart...an hour l8er they wernt sayin nuthin

 

haha comparing weed to engine cases

jamjam got engine cases and like clutch flywheel and some other bits for £20.... (for a zip 50)

 

impressive deal lol as a smoker myself it just has to be done plus it relates 2 most ppl when you bring weed into it lol some of the "smart" people that didnt get it before will look at it and be like ohhhhh i see exactly what hes saying now

 

Ive changed a crank on a piggy 50 using the mrs hair dryer, its not ideal,
but its possible

you gotta adapt improvise and over come....

 

lol i found the 4 bolts that the cylinder bolts onto is an ideal resting point 4 the hairdryer...slots in perfectly
