PostSubject: Fitting hyperpro front springs   Sat Apr 14, 2018 1:57 pm

Ok, so I've ordered a hyperpro progressive fork spring kit for my Swing, I've change fork springs on m/c's in the past and have done this with the forks in situ, just removing the caps and swapping the springs. Can you do this with the Silverwing? or is it more involved. I know I'll have to remove some of the tupperware to get at the fork tops. I couldn't find a decent decription anyware in the forum after searching.

Geoff.

Drop the legs out bud, using a jack on the frame under the engine, lift the front wheel off the ground, remove the brake caliper & pipe clamp, remove wheel, remove mudguard, now remove the legs, to do this first remove the TOP bolt completely, then slacken the bottom bolt enough to allow the leg to slide out of the bottom yolk/'triple tree'

The reason for removing the top bolt (completely) first is that the stanchion has a locating groove machined into it, if you slacken the bottom bolt first the weight of the leg makes removing the bolt a pain in the butt.

That ^^^^ or if you fancy a ride out, pop up to mine & I'll show you how, strip & refit takes 1 - 1 1/2 hours (depending on how free things are)

Or you could remove the Front Cover (fairing) and probably the Combination Meter (Dash) then the take the fork caps off and remove the springs. Then you'll need some sort of suction device to empty the fork fluid from the fork tubes.

So it's much less aggravation to follow The Bern's advice.

That's great advice, I've stripped forks before, so I'll do it the way you suggest, it will give me the opportunity to give them a good inspection. should be ok, it's only done 5k miles.

Thanks for that Bern.

I knew I'd written a diatribe before on another forum, so here goes (diatribe & my subsiquent posts in that thread + a footnote) .....

Cool, my method ....
Bike on centre stand, put a car scissor jack under the subframe (hiding under a rubber flap) just ahead of the oil filter, raise until front wheel is just off the ground.
Remove brake caliper & pipe clamp.
Remove front wheel
Remove front mudguard
Undo hose clamp on steering yoke, lift hose over & to the rear of the yoke (fiddly but 'do-able') tie calliper to handlebar to stop it pulling on the pipes.
Now it's just a matter of undoing the pinch bolts & sliding the legs out, the TOP bolt needs to be removed FIRST this is important because there is a locating groove in the leg, the weight of the leg on that bolt makes it bind & becomes a right bugger to get out (I found out the hard way), now you should only need to slacken the lower bolt, if it's too tight for the leg to drop out simply lever the yoke slit open a little.

OK legs are out, this is where the large vice comes in Wink , get a couple of bits of wood & cut a 'V' in each, now 'trap' the leg in the 'V's & clamp in the vice, with a six sided socket (not a twelve sided as it can round off the corners) & knuckle bar 'crack' the bolt + 1 turn, now remove the knuckle bar & fit a T bar, continue to undo the bolt while at the same time pushing down (the spring is under compressive preload by the bolt, NOT pushing down WILL result in bit flying around suddenly, also there is a risk of injury).
Put bolt & washer/distance piece somewhere clean, lift out spring, remove from vice & drain oil by tipping into bucket (or similar) & pumping to help clear the damper.

Optional ... Flush out any remaining oil by putting 250cc (or so) of 5w fork oil, reassemble leg & pump 15 to 20 times then drain

Put in specified amount of fork oil 7.5w - 15w, personally I favour Castrol or Silkolene but there are many other makes out there to chose from.

Re-assembly is basically the reverse process except that you will need a piece of 8mm rod with a taper ground/turned on one end to act as a locating tool, to get the leg in the right place relevant to the top bolt hole, fully tighten & torque up the lower pinch bolt, remove locating tool & fit the top bolt, pop it back together go out & enjoy :D

Will post torque settings, fluid capacity & other tech 'guff' this evening as my tying finger is now knackered Wink

....//....

Cheers, no prob's, getting the pinch bolts out then in again is a bit fiddly, but compared to the time needed to remove masses of plastic panels, it's a 'no brainer'.
Regarding the oil, order a litre (or one & a half if flushing), the initial capacity is 300cc per leg which is then 'fine tuned' by measurement after pumping several times to release any trapped air.

....//....

Right ho, back on topic ............

you initially put 300cc in each leg, pump it to force out any trapped air (as per the video) when all traces of bubbles are gone push the tube into the stanchion & measure from the top of the tube to the fluid surface & top-up as necessary to achieve a dimension of 97mm

Put the spring in closed coils down & reassemble (incase you do find secondhand springs at some point in the future, the service limit of the free length is 325mm any shorter & it's worn out)

Torque settings ...
Fork cap ................. 32Nm (2.3kgf/m .. 16lbf/ft)
Yolk pinch bolts .......... 69Nm (7.0kgf/m ..51lbf/ft)
Front axle bolt ........... 59Nm (6.0kgf/m .. 43lbf/ft)
Axle pinch bolts .......... 22Nm (2.2kgf/m .. 16lbf/ft)
Caliper mounting bolts .. 42Nm (4.3kgf/m .. 31lbf/ft)

Footenote ...

You will see in my original post I put .... "Put the spring in closed coils down" .... during conversation in that thread I was advised by Flyingpanman (also a member on here) that Hyperpro recommend their springs are fitted with closed coils upward.

THE BERN covered it. Its tight at the top but no need to remove any plastic parts.
After removing forks turn them down and pump them to remove old oil. Add a little new oil and pump them in normal position then repeat draining them.  Flushes old stuff out.

Oil level should be measured from top of tube fully compressed NO spring. I don't remember the height but its more accurate than just adding a certain amount . Hyperpro instructions should list it.
Fork oil with Hyperpro is different weight and its needed to get the most from spring change. Fork oil needs to be serviced with age, time anyway. It's harder on SW than some of your past bikes and you will need a torque wrench also and short sockets for clearance.

Honda WSM says 97mm for oil level but Hyperpro may specify a different height (I was doing fluid change only), as you say it's a bit tight, I used ring spanners to loosen bolts & 'loosely tighten' them, final torqueing was done with a 3/8" drive torque wrench & as you say, a short series socket, I used a six sided one as it seemed easier to get it seated squarley on the bolt head.
