hi

using a zx9r lump and i realise i need a 2 peice prop with a centre bearing, is this something that i can modifyfrom a suitable item or is it best i leave it to the experts, ie buy one??

psi have got access to decent engineering equipment

pps - got sunburn yesterday blind tacking - would not recommend it!

james

I ended up looking like I had been dookin fer chips after tacking up my workbench



Not angry, just sorta looked like that

Sorry no info on the propshaft!

Unless you have the equipment available to dynamically balance it properly i would leave it to the experts (they aren't really that expensive)

no matter how it is made i wont be able to balance the thing...... anyone know some good suppliers???

i used Henry fords best.....

James,

I got burnt Sunday eve tacking bits together. Face was hurting for 2 days!

I've just ordered my prop from this guy:

http://www.autoprop.co.uk

Seemed really friendly/helpful and best quote I got. He's on holiday this week though.

These guys were recommended to me by someone at Mclaren:

www.propshaftservices.co.uk

but took me 3/4 attempts to get them to answer the phone and then they weren't too helpful/friendly. (or cheap )

HTH,

James

Volvo is your friend!

I have a volvo breaker near me and they have perfect donor propshafts for becs (off a 2 litre 740 or 840 or something i think).

Joints are rebuildable meaning you can easily replace the rear yoke with one that fits a ford diff/axle. It has a centre bearing that fits nicely near the front of the tunnel, and a sliding joint. It's then just a case of chopping the front part of the shaft for length and fitting your sprocket adaptor. Did this ourselves on my mates blade westy by hammering on a cds sleve. It can only go on straight - had no vibration problems at 130 mph on the track. Alternatively get the volvo prop modded by a pro, but that'll still be much cheaper than a custom shaft.

Unless you know what you are doing then leave it to the experts. Dunning And Fairbank in Leeds are also good.

A good source of 2 piece props is Ford as as all the service bits are cheap.

It is actually possible to do your own props, a lathe and clock makes the job very easy but careful use of a hacksaw, grinder and a pen will get the job done.

Also if the job is done correctly then 90% of the time balance wieghts are not required, but you do not know this until it has been on a balancing machine. However if you check the shaft for true running after welding and total run out is less than 0.1mm on the tube I would be confident not to balance.
