I am trying to locate a new or used HWH synchronizing cylinder for my drivers side slideout. Here is the history of the part changes that HWH has made, any of these will work.synchronizing cylinder AP12484 Original partreplaced by RAP90474replaced by RAP12484newest HWH parts RAP 48733, RAP93246 hardware kitI have the newest one on order from HWH, with no ETAI checked the following places with no luck.VisoneStuartsColawI have a 2004 Mandalay 40D, if anyone knows where a salvage Mandalay may be located let me know.Also any other salvage yards would be great.Thanks

Try here for a salvage part. Search for "Mandalay".RV Salvage Parts

I emailed them last week and gave them the part numbers.They said they did not have any of the parts.But looking at the Mandalay's they have I would think there must be a match on one of them.I call call them again.

I believe that they show five 2004 Mandalay's in stock so I agree they should have the part that you need. They probably don't do their inventory by specific part number but if you ask for the HWH sync cylinder they may be able to help.

Before Bucky would send someone out to look I had to email him pictures of the part, dimensions of the cylinder, part number, and my RV info.But I wonder if they just looked for my model 40D and said nope we don't have one.I will check with them again.

Have the cylinder rebuilt by a hydraulic shop.

Cost for the rebuild was $367.

Also they had a hard time getting the thing apart, they finally figured it out, but did not give me the details. I think it took 2 extra days to get it apart.
Also they tested it with air and not fluid as their fluid testers were too high pressure for this type of cylinder.

Thats interesting. The working PSI of the HWH pump is 2900 to 3200 PSI. Doug

I took the cylinder to a local hydraulic shop where I am now in CA and they were able to rebuild it. I installed it yesterday and the slide out works great. Problem solved.
Still have not heard back from HWH on a replacement part, so I guess they are many months behind.

What was the cost? Doug

I don’t normally disagree with Doug, but i have successfully rebuilt HWH slideout cylinders and locking cylinders with readily available seals and o rings. Its not rocketsurgery. The hard part is getting the cylinders out. A trick if you need to extend or retract a cylinder is to disconnect the OTHER cylinder, cap the lines, and use the extend retract button. Of course the cylinder must be disconnected from the room.

The OP states SYNCH cylinder NOT a slideout extend/retract cylinder. You have rebuilt Synch cylinders? Sych cylinders are easy to remove and reinstall. Doug

I found a shop in Florida that have done it and would do it, but I'm in CA now.
A couple of the shops here want to see it first, so I guess I will have to pull it and then take it to them.

I asked Stuarts if they had the replacement part and they did not, but I will ask if they can repair as well.

In all the years(over 30) I have been involved with HWH and Repair, the ONLY HWH part I have heard of being repaired locally is the Jack cylinders. Doug
