hello im new here altho i have been looking at this site for a while
i am a user of the lcgb/wkfasc forums my handle is stevo 42 the same here i know some of you post on there and the SBW site so a couple of Q,s
i have a 50,s with a taffspeed sprint engine that was built in the late 80,s by terry franklin and mark green it was for a guy called declan bednall-smith who lives in my home town of cheltenham the scoot had a daytime MOT as the fly wheel was a fan a thin disc of alloy and the center boss running a total loss points system the person who i bought it of tried to fit a flywheel from another vep as he wanted to have lights in doing so he completely shaged both the flywheel and the crank i stripped the motor and now want to put it back toghether mark green(gp2,3and 5 and championship race winner fuck knows how many times for team vespa ) has given me one his spare race cranks and new flywheel side bearing i have heared about differant cranks and differant bearings the crank has the vespa logo on it and the rod is polished it has large amounts cut out for the inlet and measures 20mm were the bearing sits
the bearing is a ntn one and the no is n204et2x and has a plastic cage the inner is 20mm so will fit the crank and it is 14mm wide so will these be ok i will put the full spec of the scooter up if anyone is interested i hope with the help of you lot to get this scooter ready soon i want to run lights so any sugestions as to ign and flywheel (cheap as poss) many thanks steve

forgot to say the outer race is 47mm wide

Check the diameter at the flywheelside oil-seal.
If it's 20mm you can use a PK ignition and flywheel, or a HP4 flywheel with the PK stator.

and if it has 19mm you can also use a PK stator and flywheel (the old PK1 type) or for easier cabling an ET3 stator and flywheel.

And keep us in the loop with that green machine - what are the gimmicks?

who said it was green

the taper measures 19.85 mm were the seal fits so is this the right bearing ! and what bearings and seals do i need for the whole engine and what gasket set

[MiNiKiN]

bearings : see bearings topic davedaniel.proboards91.com/index.cgi?board=technical&action=display&thread=1173775723&page=1#1173812101

V50/ PV gasketset from VE-supermarket or your local dealer
as oil seal kit (ensure the crank seals are proper ones, such as cortecco)

[stevo42]

is this the right one 6005 simplybearings.co.uk/shop/p7110/SKF+6005C3+Deep+Groove+Ball+Bearing+Open+Type+25x47x12mm/product_info.html
im confused as the bore(d) is 25mm and the the crank is 20mm ???and they are only 12mm deep and not 14 like the 204

cheers thats the flywheel side the clutch side has 4 journals on it the threaded one 12mm next is14mm next is17mm last is 22.62 so the nut goes on the thread then ? then the bearing then the seal is that correct i know jack shit about vespas just want to get my head round it befor i start so i need a clutch side bearing that has a 17mm bore 14mm deep and 47mm across and is a single piece bearing unlike the flywheel side which is a 2 piece bearing similar to a lambretta flywheel side nu2205
