Fork Seals

[cash1000]

I've got to replace the left hand fork seal as its leaking. (Dripping on ground) I've tried cleaning seal with no success.I think its past that.

The workshop manual specfies SAE10 weight oil. What is this in fork oil grade 7.5? 10?

Also I had the forks revalved and new springs using Racetech products.

When I dismantle the forks how different are they going to be to that shown in the workshop manual?

The local Guzzi dealer can supply the oil seals over night but the dust seals will have to come from Italy which is at least 3 weeks delivery time.

Do I have to replace the dust seals?

I don't replace them if they still have some tension on the fork tubes, and don't have any nicks in the seal lip.

 

The used ones probably have less friction anyway.

No, normally you don't need to replace the dust covers. Give them a good inspection and reuse them if they're ok.

Fork oil? Now that's a can of worms. 10 wt. from one manufacturer does not equal 10 wt. from another manufacture.

Love that fork oil weight chart!

 

Peter Verdone has one, too:

Some have found better compliance with V11 forks (in general) with lighter oils measured in centiStokes.

 

The BelRay 5wt I like is 19.50 cSt.
