Crank recon v's rebuilt

[fubars]

Any pros and cons to the above ?

Is that not the same thing 🤔

Do you mean new pattern or rebuilt original?

I suppose if you put it that way a rebuilt one will end up a pattern, so it's a pattern or a pattern really.

There are aftermarket complete cranks and there are refurbished/rebuilt original cranks, which may contain non-OEM parts. There may be some OEM NOS cranks if you can find one.

Yam still sells new cranks for ypvs

If LC it's pattern only

Yes thank the banshee crowd for our YPVS cranks!

I'm not sure i understand the original question...

'recon' is short for 'reconditioning', which means taking it apart and rebuilding it with new parts as needed... so is the same as 'rebuilt', no?

If so any 'repaired' crank can contain repair parts that are OEM or aftermarket as Yam still sells bearings etc.

Ok, as both Steve and Rob say i think you mean 'aftermarket vs rebuilt', is that right?

If you can rebuild your old one and know it's OEM Japanese then do that. Dont have it welded, once its welded rebuilders dont want to touch it.

If youve blown it so badly enough to need bigger parts, places sell parts you can have fitted to rebuild it. these are both OEM and aftermarket (eg yambits sell part cranks).

But, Are you sure what youve got is OEM and is worth saving? ie how do you know youve not got a cheapo Asian sourced crank in there now that needs work?

Aftermarket cranks vary in quality, but the best ones can be spec'd with better bearings so its not all bad.

Depends on what youre building and what you want... And what bike you are asking about... the ypvs and LC parts supply is quiet different, not all 'RDs' are the same.

I'm starting to dismantle my LC engine. And was just wondering which is best to get the existing crank rebuilt or just get a "new" crank.

For all I know the existing crank may last another 10 years without problems but it's a risk that probably not worth taking.

Just wondering from a financial and reliability point of view if it's best to get the existing crank rebuilt or to buy a new one.

I've done both. Had an existing crank rebuilt with parts where needed, and I've also bought a new crank where every component is brand new. Never had an problems at all with either. The key is to get a firm you can trust to do a good job, and will use the best quality components available, which invariably means jap rods, bearings etc. Ive always used Paul Vetere at PJME in Wolverhampton for both the rebuilt cranks and also the brand new one I put in an Lc, as I trust his workmanship and the quality of the parts he uses. He spends a good deal of time getting them balanced correctly which is really important too. Here is a crank rebuild on a 400e, to show what the process is for rebuilding an existing crank;

Thanks Dusty I will probably send it off to PJME when I get it out.

You can send your crank off to a rebuilder only to get a call telling you the it needs new webs. PJME sell new cranks, not exchange, I think for £350. VFM I think.

Just had a look £418.80 with Vat.

Norbo's cranks were around half that, not sure about the latest prices though (on his website??) send him your old one, new one arrives a few days later

Not if you want a new one. They are listed as £340 for all new cranks, but exchange weirdly. So 2 x hefty postage.

OEM yamaha ypvs cranks have been talked about before, Steve (I think?) bought one and even with imports it was good value.

Did you get sorted ?

In the end I got a refurb crank from Norbo for £200 and swapped it at his house (no postage), as I had a job near by. So its a "used" crank with new conrods/big end bearing, mains and lab seal etc. If the crank being put in for refurb is a pile of pants and cant be used ie. web pins US, then Im not sure what Norbo does, as a new web will be needed to make a good crank and I think they used to be £45 a go.
