Atwood Landing Gear Repair

I purchased a 20 year old Glendale Titanium 5th wheel last year - which hadn't received regular maintenance from what I could tell from various issues I've had with the unit. One issue was noisy operation of the landing gear, and vibration in the landing gear mechanism. Visual inspection of the landing gear mechanism in operation from the basement door showed the gearbox rotating back and forth about an inch on each revolution of the driveshaft, this clearly wasn't normal, plus I had broken tabs on the plastic gearbox case which allowed the gearbox to move excessively. I decided to make some repairs and try to resolve the noise and make the landing gear more reliable. 

The first step was supporting the front of the fifth wheel. My truck has an 8' box and I've only got about 12" of clearance between the back of the box and the front of the basement when the truck is hooked up. I decided to crib up the front of the unit so I could take my time with the repair, and have good access to the basement to completely remove the landing gear. 

Supporting the front with 4x4" cribbing

Once I got the front of the unit supported on the cribbing - with the cribbing directly supporting the frame, I tested the stability before removing the landing gear. It wasn't quite as solid as I expected, so I installed some cross bracing and that removed any side to side movement on the cribbing. Two 2x4" did the trick nicely. 

Cross bracing makes the cribbing much more stable. 

With the front now supported by the cribbing - removal of the landing gear is quite simple. Remove the leg extensions by undoing the pins and pulling them off the landing gear lower section, and then raise the lower sections completely to facilitate disassembly of the landing gear from the trailer frame. 

Landing gear legs removed through the basement hatch.

The landing gear is held to the frame by two c shaped brackets with bolt clamps. Simple to remove once the crossbar has been disassembled. 

With the landing gear removed, disassembly is very straightforward. Belco, my local RV parts supply, had an aftermarket aluminum frame replacement gearbox at a reasonable price, about $100.

Swapping the gearbox is very simple - several long machine screws hold the motor to the gearbox. It's a straight swap.

This is where I found the main shaft between the gearbox and the driven leg bevel gear was bent.

The gearbox came with a new bevel gear shaft, so that would take care of the rotation of the motor and gearbox on the driven landing gear leg. Close inspection of the short bevel gear shaft showed some damage to the shaft - a vertical crack in the shaft caused by the leg being driven to full stop under power. It would be a matter of time before this shaft fails. 

Note the crack in the shaft running from the lower pin hole

When I compared the two shafts, I noticed my longer bent shaft didn't have any cracks, and could be shortened to replace my shorter cracked shaft.

I also purchased a new set of bevel gears, which comes with new roll pins. 

Disassembling, greasing, and replacing the acme screw. This is a messy job.

I don't have a lot of photos from this part of the operations - my hands were covered in high pressure grease - difficult to operate the camera with greasy hands and I wanted to get this part of the job done fairly quickly. Re-assembly was straightforward, as was replacement in the RV. 

Once the landing gear was replaced in the RV, I resealed the openings around the landing gear legs with black silicone caulking. Black duct tape was used as a mould for the silicone, to help it set in place and keep the sealant tidy.

Let me know if you have any questions - the whole job took a Saturday with all the parts in hand. 


Repairing Cargo Latches and Replacing Seals on a 2001 27EXB (28E33B) Glendale Titanium 5th Wheel

We bought this 20 year old RV earlier this year. One item to repair were the cargo latches on the flip-up door next to the bunk beds. The spring action in the latch was weak - so when you depress the release tab, the lever would not spring up to open the latch. You would have to reach under the level with a fingernail and try to pop it up. In addition, the latch seals were completely rotten, allowing water to get into the door can causing the start of some black mould and rusty hardware.

Starting point - seal half gone, weathered latch body

Some exhausting internet research and I managed to find the same latch for sale on an Asian e-commerce site, however, the inside lever which holds the latch closed did not match my latches. I couldn't find an exact match anywhere, so I decided to order the similar latch and attempt to swap the inside levers from my old latches to the new latch body with new springs and lock cylinders.

A few weeks later the new latches arrive, and luckily, they are physically similar. I start by disassembling the inner lever on one of the new latches by drilling out the rivets. The rivets are actually part of the inner lever casting - so when I did the same on the old latches I was very careful to remove a minimum amount of material with a twist drill to facilitate reassembly. 

With the rivets drilled out, the inner lever pulls apart from side to side.

It was then straightforward to transfer the inner levers from the old latch onto the new latch with new springs. The dimensions were all accurate, the o-ring seal which keeps water out of the latch mechanism was transferred off the old inner lever to the new inner lever and everything went back together with some gentle tapping and plier pressure.

With the inner levers swapped, it was simple to reinstall the latches in the cargo door with the new seals provided with the latches:

Here's a photo of the old seal next to the new seal - this was the better of the two old seals - the other seal had completely disintegrated.

Finally - I reached out to the latch vendor, and ordered some spare sets of seals if you just want to replace your seals. Just click on this link to take you to the sales page on eBay.


A&E Dometic 8500 Awning Repairs on the Glendale Titanium 27EXB

This post is part of the RV project series. In January 2021 we purchased a 2001 Glendale Titanium 27EXB for a good price, which needed a fairly significant amount of work. Check out all the articles here. The first time we opened the awning was on our first weekend camping trip, and we found the following problems. 

A&E Dometic 8500 series awning

Broken spring on one of the support arm lift handles - pin won't engage in the support arm holes

Lift handle removed, the pin is still there, but with a broken spring it won't engage on the support arm holes
Cracked hardware joining the rafter arm to the support arm

Repairs to the broken lift handle was fairly straightforward. Drill out the rivets holding the lift handle to the support arm, and then use the rivet supplied with the Dometic replacement part to reattach the lift handle to the arm. This repair took about 20 minutes from start to finish. While the lift handle was broken, to use the awning, we used a screwdriver inserted into one to the support arm holes to extend the support arm. 

Removing the broken lift handle by drilling out the rivets

Another issue was cracked hardware joining the rafter arms to the main support arms. There is a complicated casting that slides in channels in the main support arm. In my case these castings were cracked and very close to failure. 

Notice the cracks on the left and right of the white metal casting. Ready to fail.

My RV repair shop had the appropriate parts. The first step in the repair is to remove the rafter arm extension which is riveted to this hardware piece from the main support arm. To do this - you need to momentarily lift off the casting at the top of the support arm which supports the awning roller. Important - this casting is under spring tension - when you lift it off it will let off the tension on the spring of the awning if you don't restrain it. I used a set of vice grips to hold onto this casting to keep it from spinning, and I supported the weight of the awning roller on the top rung of an adjustable ladder while performing the repair. The awning needs to be opened in order to remove the rafter arm. 

Vice grips with a piece of plastic protecting the finish of the piece. Ensure the vice grips are securely attached so that spring tension doesn't cause the casting to spin.

Replacing the hardware element is fairly straightforward. Drill out the rivet holding the hardware element to the rafter arm, and then replace the part with a new rivet. The trickiest part is forming the head on the new rivet - it's not a pop rivet, so you need to use a ball pien hammer and punch to form the rivet head correctly. 

First step is to drill out the rivet to release the old part

Install the new part and insert the new rivet

This is the rivet head before forming. I used a roll pin punch with a rounded head to splay out the rivet material, once it was in a cone shape, I used the ball end of a ball pien hammer to roll down the rivet material and finish installation.

These are the old parts - note the damage to the part on the right. I replaced both parts since I was at it.

Total time for this hardware repair was about an hour. You need to extend the awning, and finding the method with the vice grips to keep the support arm upper casting from spinning took some time. 

The next issue with the awning was a series of cracks and holes along the top edge where the awning material is exposed to the sun when the awning is rolled up. I simply used a roll of CAMCO clear awning repair tape to fix these cracks and holes. I performed the cleaning stages carefully - first pass with rubber roof cleaning agent did a fantastic job removing dirt and grime and getting the surface quite clean. Then - prior to applying the tape, I used rubbing alcohol to remove any traces of grease which might keep the tape from adhering properly. This tape is very sticky, applies easily. I used a clean cloth to work the tape into the awning fabric for good adhesion. So far, so good.

Another new project - the COVID pandemic Fifth Wheel RV Recreation Plan - Ford F250 and Glendale Titanium 27EXB

Just when I thought I had enough on my plate, my wife and I decided to finally execute on the RV project we've been thinking about for years. We've rented C class motorhomes a couple of times now - I always liked that when you rent an RV - someone else takes care of winter storage, repairs, license, insurance, and all the rest. The only downside is the availability of a suitable unit that fits your family. The last C class rental we did, the arrangement of the bed didn't fit well with our family and schedule. The kids are too old now to share a bed, so that means one kid is down on the couch in the middle of the RV, and if that kid is a late sleeper, you have a problem when trying to get going in the morning in the kitchen. And so on.... 

The other issue with the C class is that you need to tow a vehicle if you plan on setting up camp and sightseeing - not impossible, lots of people do it, but this is impractical with a rental. 

So - we ended up going with a pre-owned 2012 Ford F250 4x2, and a pre-owned 2001 Glendale Titanium fifth wheel - 27EXB with bunk beds in the back for the kids. We made the purchase in January and are getting things set up and organized for this summer.

The truck is well suited for towing the RV - full crew cab so everyone has lots of room, and full 8' box for 90 degree turning capability with the fifth wheel. I'm happy with rear wheel drive - we don't plan to use the vehicle too much in the winter, and it has the electronic locking rear differential to put power to both rear wheels when traction is limited. The lack of 4WD saves some weight and complexity. 

I found a used Reese Titan 16K fifth wheel hitch which I installed with new rails. No need for a sliding fifth wheel hitch. Installed this myself on a Saturday, pretty straightforward. 

Installing the universal bed rail kit for the Reese Titan 16k Hitch

There were plenty of used fifth wheel hitches for sale in January - I ended up going with the Titan because of the urethane bushings which help isolate trailer motion from the truck frame. On my initial haul returning home with the fifth wheel, I was really impressed by how quite and stable everything was. Other than the weight, you really don't notice the trailer unless you're on rough pavement.

The hitch will need a bit of love, the grease fittings were seized, the jaw bushings were ungreased, and there is some rust on the frame to touch up. 

On the trailer - we got it for a good price, however there is some water damage and structural issues to take care of due to a few years of neglect. The RV is booked for the structural / water damage repairs in March, more on that in future posts.
