You can find maintenance instructions for the HYDRA in the Owner’s Manual, or you can watch a complete breakdown in this video where rich demonstrates how to disassemble the engine, replace O-rings, nozzles and more.
Video transcript: what’s its deck so this is our brand-new Gen 2 Hydra we’re going to take a look at some of the technical aspects of this we’re going to tear it down take a look at how to do maintenance basic service like lubrication and overing replacement so first thing talking about o rings you don’t really have to worry about replacing this O ring on the outside that is not a sealing overing that’s just a friction element you can replace it if you need to but generally even if it gets a little nick in it it’s not going to hurt anything just go ahead and do basic disassembly two halves of the unit will unthread those of you that are familiar with the gen 2 inferno we’ll see some familiar stuff here that spring looks familiar the baffle there or the half of the baffle looks familiar and this gold poppet in there looks familiar I’m go ahead and take the valve out if we want to disassemble the valve housing which again this is not normal maintenance you would only disassemble this if you have a leak from maybe the back of the valve housing here the valve housing is two pieces one to the airline adapter and the other is the main valve housing so the only real reason to do this is if you have a leak between those two pieces but there’s a c-clip here which you can pop off taking care not to hurt yourself in the process so there’s our c-clip these two pieces just slide apart see there’s an o-ring here over in here if you’re having a problem with the leak there you can replace those two o-rings with the provided a ring from the o-ring kit or with a replacement o-ring kit to reinstall it you just have the port the port where the airline attaches to the back it will only go together one direction if you try to go the other direction you’re going to have trouble it’s going to sit like that and not really go together slide that on take the seat c-clip and just snap it in place make sure we push it all the way on there so it snaps in place so that’s your valve housing if you’re dealing with replacing a nozzle or needing to just fully disassemble the front half of the unit you will want a 3/16 allen wrench and you can go the back of the nozzle has an allen key in it so again if you’re familiar with the Gentoo inferno you will notice these are these parts look familiar these are all the same parts nozzle back the poppet o ring the baffle assembly there that is all part the same parts from the gen 2 inferno so it works exactly the same way which is why you get great performance out of it if you need to replace the nozzle you’re probably going to need the change of the nozzle offset so this is a tire 21 nozzle so we’re using the offset for the tire if you need to change the position of the front bushing plate there are three small Phillips head screws and then you can rotate the bushing plate to whatever offset position you need we’re going to put this nozzle back in so I’ll put it back how it was we do recommend using a little dab of tiny little dab of Loctite on these screws just to make sure they don’t shake loose during operation but if you don’t have it don’t stress about it too much it’s not normally a problem but we we do that with your initial assembly just as a precaution to make sure nothing goes wrong snug those down now you’ll notice that the tar twenty-ninth one nozzle I’m able to put in from the back most nozzles the offset is too much to be able to do that it won’t fit so you need to place the nozzle in first and then then put your bushing plate on but with the tire 21 we can just drop it in from the back and it’s not a problem now this assembly there’s two part baffle you have an o-ring here this is the o-ring that everybody always messes up on these systems this Oh ring goes on the top side of the baffle not underneath in between the the battle and the poppet here it goes right here around the gold part our nozzle back is already in there we will want to put a little bit of blue loctite on those threads so that when we thread it back into the nozzle it locks in place and we don’t have to worry about it coming loose spring valve housing threads right back together will just point one more thing out the Hydra works really nicely for showing people what the what is going on because you can actually see both the poppet and the nozzle and see that they can move with respect to each other if you’re still not clear on what’s going on the system what happens is they move forward the nozzle stops first but then the poppet the Prophet can actually can’t do it without scratching the top of there but it can actually move further forward there’s like gap here between your nozzle and your Papa to the poppet can keep moving forward so your novel moves forward all the way first it closes the BB and the hop-up then you have this pause while the poppet is continuing to move forward and open the air flows fire to BB so that pause is what stabilizes the BB and gives you really good precision with this system so that was your quick technical overview of the gen 2 Hydra I hope this was helpful to you guys as always leave comments or questions in the comment section
