K fork springs orientation?

Post by **oldgreyandslow** » Mon Mar 12, 2012 8:24 am

When I removed them I found the fork springs have the closer wound coils at the bottom, howveer reading the Haynes manual on the installation section it states "install the spring with its closer spaced coils at the top"

So did the previous owner fit the springs the wrong way up, or is Haynes wrong?

Cheers

Tighter helix at the top of the forks

Thanks, that means the previous owner had them in the wrong way round! I even sketched the arrangement as I took it apart to be certain I put them back the same way too, I hope it won't have damaged them.

Shouldn't have damaged them, it would have just fcuked up the handling under heavy breaking.

Look closely at each end of the spring, then down inside the stanchion where the spring seats on the damper body.

If one end of the spring is tapered, i.e is a smaller diameter, then that faces down and sits neatly on the damper body. [normally the close coils]
The smaller I.D goes to the bottom on L model and 750.

Only if the spring has no taper, then close coils to the top.

You will do no damage if both ends of the spring are the same diameter, if not, the larger end will not sit well on the damper.

The tighter helix ALWAYS sits at the top on RWU forks, they only fit the opposite way on USD forks.

Not if 1 end is tapered, see common service manual.
vfr570 is tapered on close coil end

The springs are not tapered, either end seems to sit OK on the damper, so I assume its close coils to the top

Yes and yes.

That's right.
Not sure if they compress any different progression wise either way up, but best for unsprung weight.

Just like the Clubman Bantam rear shocks :-)
