I have just finished resealing my fresh water hose reel assembly. IT CAN BE DONE!
One of the biggest problems with gaining access to the reel is taking the lower part of the reel bin apart
. I found that a 50/50 mixture of Acetone
and automatic transmission fluid
will penetrate the rusted bolts, so they will come apart with no trouble
. Really, you must give it a try. Just make sure you do not get it on your paint.
Start by removing the 7 bolts that hold the lower bin section on, and get it out of the way.
Use the mixture on the two self locking nuts on the back side of the bin that hold the reel. I put a floor jack under the reel to support it as the bolts were removed. Unscrew the lower union nut on the plastic water line. Make sure you do not put any strain on the plastic. With the help of a screwdriver, you can then slide the plastic tube off of the union. Make sure the reel is in the "locked" position, and take the lower hose roller loose to get the end of the hose out. With the reel out of the coach, now the repair is easy.
With care, let all of the spring tension unwind from the reel by letting the mount rotate slowly until it wants to stop. Mark the orientation of the fitting, and remove the plastic 90 degree fitting from the hose shaft. Loosen the lock nut on the large set screw, and remove the set screw. Now pull the mount off of the reel shaft. Once the mount is removed, take spring holder loose from the reel by removing the small nuts around the outer edge, and pull it off of the reel.
Now turn the reel over and remove the hose from the brass adapter. Remove the spigot from the end of brass adapter. Remove the snap ring from the end of the shaft, and pull the shaft out of the brass adapter. Remove the 3 small nuts holding the brass adapter to the reel, and remove.
I cleaned up the inside of the brass adapter with some very fine sandpaper. The two O rings on the shaft are standard O rings that are available at Ace Hardware. I replaced the drain spigot with a brass pipe plug and Teflon tape. Get a pipe plug that fits the other end of the shaft as well. (The end the plastic 90 goes into). This is a good time to replace your hose. Get the best 25 footer you can.
To reassemble, start by attaching the new hose to the brass adapter with a new hose seal, and let the hose lay out through the opening in the reel. Attach the brass adapter to the reel with the 3 small nuts. Be careful to not over torque the nuts. Lube the new O rings with silicone grease, as well as the shaft, and the inside of the brass adapter. Slide the O rings onto the shaft into their locations. Carefully slide the shaft into the brass adapter, and replace the snap ring. The pipe plug should already be installed in this end of the shaft.
Now the spring holder is installed onto the reel, being careful to not over torque the small nuts. Looking at the mount end of the shaft, you will notice that there is a small relief in the shaft where the set screw will seat. Mark the end of the shaft with a marker so the relief can be lined up with the set screw. Slide the mount onto the shaft, and install the set screw. Tighten the screw and then the lock nut.
To do a leak test, install the other pipe plug into the shaft loosely. Hook the hose to a water source. Let the air out of the unit by loosening that last plug. No leaks...good. Wind the spring back up by holding the reel and winding the mount. If there seems to be no tension, you are going the wrong way. It will only wind up in one direction. I think I wound mine up about 12-15 rotations. Put the reel in the "locked' position.
Now the unit is ready to put back into the coach.
Install the plastic 90 into the shaft with teflon tape, and put back to it's original orientation. As you jack up the reel into the coach, just slide the plastic tube back onto the union. Leave the union loose until the two reel mount bolts are tight, then tighten the union nut. Put the hose through the rollers, and now you can pull the hose to unlock the reel and let it wind up. Replace the lower bin section, and you are done.
Good luck and have fun, Rob
