Seized Fork Seals 🙁

Actually, despite me thinking these forks had never been apart in their lives due to the rank foul smelling oil in them, on reflection they must have been as
a) the spring (progressive type) in the RHS leg had been put in upside down, and
b) neither fork leg had the requisite washers at the top and bottom of the spacer. items 4 & 26 in the parts diagram were missing.

As a consequence the spring in the RHS leg had become stuck up inside the spacer at a jaunty angle 😮

I’m now awaiting delivery of new bushes, as the ones in there are well worn, before I can reassemble the forks and reinstall them.

Well done !
Good man yourself .....
..... so it is ! (y)

So what is the take-away lesson from this ?

Brute force / violence wins out over reason and caution ?

:):):)
Full Knowledge is omnipotent, a little knowledge is dangerous. I’ll admit to the latter in this instance, believed, based upon shoddy research on my part, the hex bolt at the bottom was purely for draining the oil with the forks in situ. All I can say is never believe what you read on specialist motorbike forums (not this one obviously). Mea culpa 🙁

I thought the exact same thing when I started reading this , but I decided to keep my gob shut
...... because I could see it leading to a possible argument ....:rolleyes:

Very interesting about the progressive springs having been fitted in opposite directions .
But I'm betting that the previous owner / rider never noticed any front end problems at all ........
......and why would they ?

As long as both legs had oil in , it barely matters which way round the springs were fitted .
They are both going to get compressed , progressively , and it doesn't matter a pig's burp
which end the compression comes from .

Could someone please let me know if I have imagined this .....

.... but I'm sure I read about a make / model of bike which comes straight out of the factory with all ( or most )
of the springing in one leg ?

:unsure:

It’s not uncommon, springing in one leg, damping in t’other.

I think my Multi V4S must be like that as you can only adjust preload on the RHS leg and the electrical connections for the electronically controlled damping are on the LHS leg.

Yes, most now have rebound in one leg and pre load in the other - but not springing in one as far as I know 👀
