Had a very slight leaking seal, mainly when the bike isn't used much, but the oil hasn't been changed for 10yrs and 25k miles so this job is well overdue. Please don't take this as a "how to" as I'm no expert and its my first time working on forks, apart from an oil change on the Thruxton's Showa BPF forks the week before. Its all in the Triumph workshop manual anyway. Wheel off and forks out with no drama, remembering to crack the fork cap first, the fork top cap loosened fairly easily with the pin wrench after releasing the top yoke. top cap unscrewed, there's no spring pressure at this stage. Then hold the top cap and slacken the locknut, both 17mm but a standard (mine anyway) open ended spanner wouldn't reach the nut so had to use an adjustable which had longer jaws, luckily its not massively tight, the plastic bag is to protect the top cap. Then hold the damping rod and unscrew the nut to release the spring, deep socket was useful for this, the reverse of this stage is the only tricky bit in the process. Then you can remove the spring, spring spacer and adjustment rod and pour out the oil, remembering to catch the damping needle and spring, or fish them out the oil with a magnet. Then you can separate the inner and outer tubes and clean everything, a full stripdown would include removing the cartridge but that needs more specialist tools and wasn't necessary for this job. Oil was a bit manky as we say up ere, not sure if the Ohlins oil is coloured originally or supposed to be clear. Can see how bad it was around the seal area, seal removed ok, warmed the outer tube gently with a blowtorch first as I don't have a heat gun but would have probably come out regardless. everything apart, hope i can remember how it goes back together No wear showing, plating in great condition. Used Ktech supplied oil seals which I think are Ngk, dust seals were ok so cleaned and reused. Went for Motul 5w as from the viscosity charts I've seen and other peoples recommendations its supposed to be the nearest equivalent to the original Ohlins fork oil Filled with 0.5l then level set to 150mm below top tube with my homemade oil extractor, just sucking on a tube, then a good while moving the damping rod up and down until all the air is purged. Didn't take any pictures of re-assembly, basically the reverse process, the only tricky bit is holding the damper rod up while you drop the spring in, there is a triumph tool for this but most people just use a piece of wire around the thread, then grip the rod with long nose pliers through the spring while you fit the top spring seat and hopefully have a couple of threads showing to start the nut. Ready to go back, bit of red rubber grease on the O ring. Back in the bike, initially thought the forks had been set incorrectly originally but then re-read the manual and realised the fork pull through is 12mm to the top of the outer tube and not the top cap of the fork, not before I'd tightened the forks and put the wheel back though Would normally use the clip ons to hang the calipers and not the indicators but awkward when removing the forks, made sure the weight was right on the inside though. Will update later regarding how they feel as the test ride didn't go quite to plan.
