Wee K9 Fork oil check query
« on: July 30, 2017, 14:49:34 »
Previous MOT report suggested oil misting on leg may be due to seal failure.

And applying the front brake caused swift plunging front end.

So then is there a way to check the oil level / grade is correct?

I can find no traces of oil under the fork gaiters that I fitted and wonder if it has mostly gone / leaked away .

I have screwed in the preload but it seems to make little difference.

Oh! yes!  my weight ...... I am 18 "ish" stones

According to the Haynes manual the correct way to do this is to remove the fork leg from the bike, remove the spring, then fully compress the fork stanchion. Keeping the leg vertical you measure the depth from the top of the stanchion to the oil level. The distance you are after is 139mm. If you have to the agro of going this far you would be best draining the old oil out and filling with fresh stuff...

Thanks Paul,
Hmmm yes that is a lot of mucking about so as you say I might as well change the oil. A wee job I'll keep for the colder off road months.
