Good luck with that Tonytony.mon wrote: ↑Mon Feb 05, 2024 11:41 am Today I ordered the tools, oil and seals I need for the Ohlins fork rebuild on my Aprilia. Although they're semi-automatic electronic forks the rebuild looks to be the same as normal mechanical ones apart from unplugging the loom connector at the fork cap. They're not nitrogen-filled, so at least that isn't needed.
It's now done 17k, so it's about time for a refresh, but it reminded me it was due by leaking oil at the recent MOT.![]()
I already had a 43mm seal slider to fit the new seals, but needed to buy a fork leg compressor. I went for the full-length Sealey one rather than the little circular clamp with two handles. With the full length one you can do the job without a second pair of hands, plus it can be clamped in a vice to hold the leg at a convenient height.
(Thanks for the advice, Jonesy).
I also needed to order the (hopefully) correct pin socket to undo the fork caps. There's no nut, just eight holes, so you need a socket to fit with the pins of the correct diameter and pcd.
I'll know when it arrives whether I measured correctly!
I ordered Ohlins seals plus Ohlins dust seals and Ohlins 5w oil. I fully expect that an aftermarket set would be fine - and cheaper- but I prefer to spend a bit more first time round than have to do the job again in a few weeks, as I had to one time when I used pattern seals on a set of Blade forks I had on my Storm.
So far that lot has cost me £210, which is about what I would have spent taking the fork legs off and dropping them into a suspension specialist. But next time it will only cost me seals and oil.
I'll take some pics and post them afterwards. Ohlins forks are the same as fitted to a number of bikes, e.g. Yamaha, Ducati, etc, so this will be applicable to all Ohlins semi-auto forks. For instance Ducati call theirs Mechatronic, but they should be the same construction, just different dimensions, shimming, spring and oil weight and air gap, so are variations on a theme. But check!
It should be pretty similar to CyberCarl's old thread in the workshop knowledge base, (but without tipping the old oil down a drain)! We'll see, when the orders arrive.
