S Drive Shafts?

[graham in aus]

I have always believed that S driveshafts have the raised ridge in them, like the two centre ones here?



Also, compared to the non S ones either side, the S ones are a bit shorter? is that correct?



I always though the shafts were all the same length?

Cheers!

Hmmmn.... Tumble weed rolls across the thread!

Anyone care to confirm these as S driveshafts?

yep, dead right Graham

as in the "S" shafts had the raised lumps & are a tad shorter

Aah you can always rely on a goodfernuttinlazyassmountainbikinsurfinfreakinMiniMechanic!

I guess a bit shorter 'cause of the general differences / positioning with Hardy spicers, different hub (vs Drum) etc.

Cheers Matt!

Hi Graham,

I read your post yesterday but didn't comment cos I didn't know. The "S" shafts came out in 66 & I have never had a car as late as that.

Thanks for teaching me something, if nothing else.

The ones with the raised ridge on them are later shafts, the earlier ones used on cars with rubber couplings don't have these markings, regarding the length I would have to check.

i was always lead to believe that the bump is on the shaft to stop the hardy spicer going over centre when the suspension is at full droop - the bump rubs on the suspension pin and acts like a crude stop

Really? now that's interesting! or is my leg being pulled? Sounds a bit agricultural even for BMC!

Are these shafts found on the autos too ? (should be if the hump is to limit travel - yes?)

Also - any other difference on these shafts? Are they stronger? Better steel etc?
