Extending drive shafts??

[95civic]

Hello all,

With the engine conversion I am currently doing one drive shaft is too short.

As a temp fix, would I be able to cut the shaft, machine up a sleve to join both parts of the origional shaft back together resulting in an extended shaft??

This would only be on the car for a short amount of time while I get myself some custom shafts. I dont want to spend the big $$ before the car is up and running.


Any thought would be great.

Cheers,

Campbell

maybe a sleeve with a solid centre (the distance that you want to extend by).

A hollow center would drastically descrease strenght i would have thought.

Plus it would need to be relatively balanced

No luck at the wreckers?

i wouldn't. Didn't the conversion have shafts from the half-cut?
I'd just goto the wreckers or the importer to get a set from them.

Machining up custom shafts are expensive. Also rejoining them is dangerous as they will not be as strong as the original.

Unfortunatly most of the things I am doing need to be custom made. The shafts from the engine wont fit the hubs ( and they arent long enough ).

I think i will do the cut and join for now... then when I have the time etc I can make up the longer shafts.

can't you change the hubs as well?

Hmmm Im not too sure about changing the hubs, I know it is a rather easy swap on the rear but not to sure on the front.

Even if I do change the hubs i think i will still have an issue with the shaft not being long enough.

Actually using tube (Hollow center) rather than bar (Solid) offers GREATER resistance to torque forces not the other way around.

Can you give reasons why? Interesting.

momentum i believe

[teh_mechanic]

hollow allows it to flex and distribute the stress across the surface. Solid focus's the stress centrally

thus hollow shafts are stronger

Whats the conversion ?

D into a 79

We put an EW engine into an early Civic and we changed the front hubs, I would not recommend it because it changes the front end geometry heaps due to the angle of the top and bottom mount on the hub. Good luck with the conversion.
