Title: Fork Oil
Post by: Tig on April 01, 2014, 05:57:35 PM
Does anyone have the details of how much Fork oil each leg should have and how much please ?

Alternatively should it be measured from the top with the fork spring removed and if so what height should it be ?

Also the best weight oil to use.

Thanks

Hi Tig;

If I'm reading the Marzocchi Fork Manual (http://www.heskethownersclub.org.uk/technical/Marzocchi_Forks_Service_Manual/Marzocchi_Forks.pdf) correctly; pg 7 states the oil is SAE 5 and pg 25 states 400cc per leg, but feel free to double check that...

A litre of 5W fork oil will run you anywhere between £10 and £15... Loads of different brands to choose from... (http://www.ebay.co.uk/bhp/fork-oil-5w)

The Marzocchi manual also describes how to change the oil on an assembled fork leg...  They still want it off the bike though...

Hope that helps

Jeff

My MHR and SSD and also the Jota all have the same forks as the H but DUCATI and LAVERDA quote 250ml in their handbooks of AGIP F1 ATF or DEXRON or equivalent.

That doesn't help much does it!

Cheers,

Robert

Hesketh Owners Manual details the method of fork oil changing, including the warning  to do one leg at a time - if you remove both filler plugs, the forks collapse!
Manual says 250cc of oil per leg and SAE10.
But I've always found the front forks a bit stiff, so use SAE5 which fits with Mick's advise.
