Hi people, I'm about to change the springs for hagon 1's in my 31K forks, so i want to give them a bit of a flush out and new oil. Whats the best way to flush the cartridge of old oil please? What oil should i replace with? (think i remember reading somewhere 10w is the way to go with hagon springs!) Any particular make of oil to use or avoid? Cheers all  |

I just chuck a liter of the cheapest fork oil I can find down the forks, put caps back on bounce on front end alot .....warming oil up before chucking it in helps, drain it for a couple of days pushing on the forks a couple of times a day.
repeat untill clean with no chunks, water, black crud, brown crud.
worked a treat for me three times now
refilled with 10w oil, most important along with oil weight is oil level always check the level in each fork leg and match the pair not too much less is more!
hope it helps

sadly there's no substitute for actually dismantling and doing a thorough clean up.
IF determined to simply flush out some of the goo then Diesel could be a decent flush fluid. Cheap , good detergent action and it doesn't leave solvents behind.
Strongly suggest you rebuild the forks, yess! new bushes AND seals to go along with the new springs.
Also use 15 0r 20 weight oil as 10w is simply ineffective in those forks.

I've decided to dismantle and do the job properly (well, as best as i can lol).
Y new bushes though, do they wear? Assumed they was just to stop the forks falling apart!

No the bushes are THE bearings that the forks slide on/with. Fairly important :-) These are designed as wearing surfaces and need renewal.. far more often than owners assume. Bit of a pain and not free either. Pretty well a mandatory replacement imo. |
