Thank you for the video. We here at Ohlins South Africa have a good tip with that nasty stubborn circlip that is difficult to remove off the shaft. It always scratches and marks the shaft not to mention that the seal block seal might catch when assembling. Here it goes this is what we do leave it and remove the lower shock end eye of the shaft. The thread reduced to 15mm so everything slides down. No bullet tool needed. I hope this will help you.

Dear Doug, first and foremost thank you very much for your excellent videos, I'm extremely grateful for all this knowledge you're sharing with us for free, I wish you live forever in excellent health. Your videos helped me to fully understand how my suspension works and gave me hope that I'll be able to retune mine for the fraction of the cost of the aftermarket alternatives. I've one question regarding Ohlins m/c shocks: Can you replace the piggyback reservoir with a shorter one? I've an HO0841 that I wish to fit in a '94 VFR750F(after any rework that might be needed), but it seems like that the swingarm is going to hit the reservoir.
@theohlinsguy46496 ай бұрын
Thanks! A smaller reservoir wouldn't really effect anything. The same amount of oil would be in it but just less nitrogen which wouldn't really effect much. I am assuming it is a 44mm ID reservoir. The shortest one is 80mm long.

Dear Douglas, if ever you have to rebuild/service a double piston shock (S46DR1) I would love to see this in a video. Just very curious how to vacuum it since I really have no idea how to since the N2 fill opening is above floating piston. The ones I have are either an emulsion shock or have a reservoir, which both are relatively easy to vacuum. Also can't imagine how to "adjust" the height of the floating piston (it annoys me 😁). Like you I'm an engineer so always interested/curious in the correct "how". Stay healthy and have a nice weekend! Frank (Netherlands)
@theohlinsguy46493 жыл бұрын
Hi Frank. Your shock is not an emulsion shock. The D in the description means that it has a separator piston. You don't vacuum fill an emulsion shock. What you can do if you don't have to tools to vacuum fill your shock with an inline separator piston after you have bled the piston is to make sure the sep piston is high enough to contact the bottom of the shaft. push it down with the shaft until you have about 40mm left of the shaft (before the threads) showing. Then push down and install the seal head. That should do it. Don't put any N2 pressure in the shock until the seal head is installed with the snap ring in place.

Then start bleeding procedure just like in the video

Hi The needle can't come up the shaft because there is a counterbore inside the shaft. No oil goes up the shaft because of the o-ring on needle. The needle is held in from coming out the bottom by the shaft jet. The need is held against the rebound shaft by the nitrogen pressure in the canister pressurizing the shock oil

Hey Doug just curious if you could shoot me a quote for a rebuild service for my rear shock from a 2007 Ducati Monster S4RS. I just bought it but it has had a hard life and sat at an auction after it was stolen for a while. It seems fine but the bump stop has either had gas or brake fluid saturated on it and definitely needs replaced. I can’t really tell right now if it is leaking elsewhere since I’m tearing it down fixing everything else.

Hi Spencer When shocks sit for a long time they tend to leak. Easy to service and get perfect again. Depending on the particular shock the service usually runs between $210 and $230 which includes parts, vacuum filling and a dyno run to make sure it is working perfectly. That doesn't include return freight which depends on where you are. Thanks for watching! Douglas

Hi Thomas Great question. On it's face if you were splitting hairs the bladder would be the better choice because there would seem to be no stiction envolved. My take on it is that if it was better Ohlins would still be doing it. It has been my experience that Ohlins never does things just to save money. My guess is they have a good reason not to use a bladder. What the reasoning is I couldn't say. Thanks for watching!!
