Slide locking pin leaking on top of living room slide

I have a significant leak on my rear locking pin on top of my living room slide.
Searched around for awhile but didn't find anything showing how to access and remove it. I'm assuming I need to remove the decorative header and then partially extend the slide to access??

Not sure where it's leaking from but hoping it just needs to be tightened up on one of the fittings. Sounds like there's some o-rings too, hopefully that's not the problem

Yep that big long cover comes off. Screws under the buttons. You need two people to remove or more. Expect some of the screws to break. I think the actuator is not repairable and will require replacement. Get the part number and contact HWH for availability. I had heard they had a pallet of unserviceable ones there. Please post if they are resealable because I would like to also purchase a set of four for my coach also. If they are not repairable you may want to consider replacing as a set but if you dont it wont be an unknown. Extending slide fully will help with removal once that actuator is retracted. May also want to remove table top to facilitate removal.

The locking pins assembly on mine is held on with 2 hex drive bolts. You will also have to release the hydraulic pressure and remove the lines. I had a leak and sent it to HWH. They repaired it and returned to me this past winter.

Seems to me it was $100-$200.  A new one at MOT which includes the reed switch is about $700. When you handle the reed switch (looks like a small toy pistol), be gentle. They are easily damaged.

Check with Northwest RV Supply for the lock actuator.  They will give a better price than HWH even if they have to drop ship from HWH.  Fact is the unit is rebuildable ...check Newell forum for more details.  It's nothing more than O rings...

Price is about $500 ++ for a new one.  hWH will rebuild for about $375....but it's WEEKS if you are lucky.

The change is not a big deal.  Some things to know.  You MUST release the hydraulic pressure at the valves on the pump manifold.  Another gotcha is the new units have different threads... can't remember whether it's NPT or straight with o ring, but I could not use the original fittings....  A hydraulic hose shop,is,your friend.

Buy caps and plugs to seal up,all the hoses to control leakage and possible contamination.  Make sure you mark lines as they must all go back to the original locations lest other bad things can happen....

No need to bleed once back together.  just pressurize the system to latch and unlatch about 5 times. 

 Need more info, PM and we can converse.... Just did this last year....  Not fun, but not horrible....

Be careful not to disturb the Hall effect slide location sensors or you will be having other fun.....

To reinforce Rich's comment, yes, be careful with the reed switch.  I tacked mine with silicone so it would not move.

Update so far...

I have removed the aluminum block that holds the pin. There is a top cap that I removed and found a deteriorated O-ring. I found the correct O-ring locally and re-installed. I was hoping that would fix my problem and to an extent it did, but it looks like it's also leaking from the pin itself.

My hope is that someone here has removed the pin and can help me with directions for removal and any special tools I may need. I know I can send it to HWH for repair but they quoted from $200 to $400 to repair depending on the issue, not to mention I have a trip coming up in about 6 weeks and didn't want to take the chance I would not get it back in time. (Though I've heard I could probably cap off the hydraulic hoses to the pin and be fine.)

Under the top cap, there is a brass nut with a thick washer. I was able to remove that but then wasn't sure where to go from there since there is a slotted cylinder and might need a special tool to remove. I'm assuming it's threaded but not sure.

The HWH part number for the whole lock is RAP 19920. I've attached some photos for reference. They want $600 for a new one and are back ordered for an unknown time...though I'm obviously hoping to fix this one myself. HWH technical support is out weeks so I can't even talk to someone there in a timely manner.

I also posted this to the Newell forum hoping someone over there has torn one of these apart...

Thanks

Dylan,
1. correct you need a special spanner wrench
2. correct

Now you may be able to build a home made wrench if you have the tools to do so. The better option is to see if you have an old school hydraulic cylinder shop or a hydraulic jack shop. They will have the spanner that you need and may be able to rent it. The best option is if they have the spanner they will have the know how to fix that part for you as that piece isn't anything but a hydraulic jack or cylinder. This would be the fastest option to get you on the road also.

Thanks Mike, I'll call around to see if I can get lucky and find someone to disassemble for me.

I've heard the same nightmare issue with HWH...even though last week they told me they were only 5-10 business days out on tech support...we will soon see. I'm hoping I'll have it fixed and the slide in working order before that 👍

So wanted to wrap this up...

Since my last post I've learned some things. The locking pin doesn't thread out like previously mentioned. A light tap with a brass punch pushed it out. Trying to push it by hand wasn't working initially which is why I thought it was threaded. I was able to talk to someone on another forum who had experience taking these apart and set me straight.

Once the pin was out, I was able to source the 2 O-rings inside. One was by a snap ring (quad ring Part# AFM Q212) and the other was just a normal O-ring (Part# HERC 568-214). I don't have the part# for the cap O-Ring but was told it was a BOSS type, size 16, 90 Durometer. (Durometer is the hardness of an O-ring, just learned this.) I didn't have to remove the snap ring to remove and install the quad ring, just used a pick to remove then squeezed it back in.

Another issue is that the pin itself has some pitting right around the area that the quad ring sits when the pin is in the unlocked position (Slide open) I believe at some point water had leaked down the pin to the O-ring and sat there rusting the pin. I used 2000 grit sand paper and some emery cloth to clean it up the best I can though I can't guarantee it's not going to leak in the near future if that pitting area rubs back and forth on the O-ring. In the video you'll see my initial cleaning of the pin, but it looks a lot better once I finished as far as the scratch marks go.

I'm not happy with HWH at all. I've already heard some stories about their customer service and I'm sure it's not all bad but my experience confirms the negative comments I heard.
I asked how much it would be to just replace the pin and he said they couldn't sell me just the pin...wouldn't tell me why. Then I asked how much to send it in and have them replace the pin...he said a maximum of $400 but could be less. (mind you I can get a brand new one from Foretravel for $540 with discount) I pleaded with him to go ask his tech guys to at least give me a ballpark amount so I could make an educated decision...he said nope...I said that's not cool and he said we've been in business 55 years so I think we're doing just fine. I hung up on him.
Yeah, they have a proprietary piece of equipment that only they can produce so they can do what they want, guess they win.

I'll post some pics and a couple videos of my experience with the process...

Dylan a good machine shop (Good luck finding) can grind the shaft undersize then hard nickel plate back to standard size. Some shops can do chrome, but I always worry about them peeling off. Glad to hear you got it sorted out.  So in watching your video did you apply any type of corrosion preventive to the shaft were the pitting was. Im concerned that you have lost the finish by removing corrosion. This will accelerate future corrosion.  That area is subject to wear from the receiver it is in while slide is closed and pins extended. Make sure your drains in the receivers are open and clean. Drains exit on the bottom side of your slide. I honestly think that is the source of your corrosion issue to start with. Also It is critical that the outer upper fiberglass were the recievers are located are sealed. This can cause leakage of water as you have seen in your structure. Foretravel has know problems with the adhesive used and mine had totally failed. You show the upper skin being loose in one of your videos in the extended position. I'm guessing it is worse in the retracted  unloaded position.

Thanks Scott, didn't  put any corrosion preventative on the pin but I still can...is there something you recommend?
I'll also check the draining on the recievers. Is there a best practice to clean out the drainage on those? Sounds like I'll need to remove slide awening to facilitate a good drain cleaning.

Dylan;  on cleaning out the tubes that are used for drainage, put some rags over the top of the slide to prevent dirt and debris from getting on your slide awning and blow up from the bottom of the slide with a compressor.  As far as I know, that is the only way to clear the drains.  The line for allowing the water to seep down is very small and they clog easily.  By the way, great write up and documentation for others on here!
I am not a fan of HWH and when I had our coach, swore I would not spend another nickel with them.  Sorry customer service and it will come back to bite them someday!

Black oxide coating if there were still apart. The drain holes are in the bottom of the slide. Like 1/4" tubing. Like under say 30 psi to blow it upward. Mine were both plugged full of junk yes the awning needs to be clear. Will facilitate viewing the the receiver also. I recall clearing out the hole a little with a drill bit before they would clear with air .

Thanks, appreciate it. Hope this helps someone in the future.

So the drainage tubes are separate from the receiver holes, or are they up inside the receiver hole? I don't seem to remember seeing any drainage tubes on the bottom the slide...but maybe they are so small I didn't notice them.

yes small and outside of were the bladder seals so moisture when slide is retracted is out side drained. I was concerned of blowing the lines apart causing the leak to be inside of the coach slide. That would be bad. Clear the top out and dig out the center with a 3/32" drill? Holes may also be on the side of the receiver tube also. Anyway remove all you can
