I just received my shock back from it's service. Last fall I noticed there was a light mist of oil on the hydraulic preload adjuster body. Never lost full charge, but it was set with 4m of additional preload and was now sitting with only 2mm.
If it leaks one time I figure it will leak again, so I decided to see if I could convert it to a simple threaded adjuster. My shock is a yacugar and is not a very popular up here in Canada. I was quite sure it shares a lot of it's parts with the Hyperpro shocks so my plan was to get it serviced at a suspension shop that sells Hyperpro as they would most likely be able to confirm their adjuster will work and source the parts for me.
While it was there the virus hit and issues sourcing parts became an issue. They were able to come up with an alternate solution of using the inner portion of my current hydraulic adjuster, so we went with that.
I have a longer 170N spring in the garage and wanted to give it a try, so I needed to make a spring seat for the top of the shock. The stock seat was very narrow at 4mm and I didn't feel comfortable with it. Luckily I have some 6mm sheet aluminum and some patience. Spent some time with the jigsaw today making a new seat approx 10mm wide and modified an old spring preload wrench I had kicking around to fit this shock. I also bought a new Torrington bearing for the top seat to make adjusting much easier.
Maybe not the prettiest but it works and it will never leak. I generally get the bike setup for normal riding which is with a top box with a few tools and then a second preload setting for fully loaded for traveling or camping. Having a manual adjuster vs a hydraulic is a non issue for me, maybe a few minutes more to change the setting.
