I just replaced the rubber hinges on the two right side bay doors of my 4108, six months ago and now 3 out of 4 of them are ripped and need to be replaced again. What did I do wrong???
Reason I replaced them is I re-paneled the doors and installed new hinge material when I put them back on.
Steps that I took to replace them.
1. Cleaned the track till hinge material would slide easily through the track.
2. Used spray silicone lubricant to lubricate track and hinge material
3. Installed lower hinge to door.
4. Installed upper hinge first.
5. Install torsion rods .
I’ve opened and closed doors now maybe 3 to 4 dozen times and they are shot. HELP!!!
Thanks,
Mrbill4108 |

Do NOT use silicon on rubber parts. I use a good coating of armorall rubber protectant. Its slippery and is good for the rubber. I also can recommend using Bonny's Bison-tuff hinge material. I saw the ad in the National bus trader. The hinge has fibers moulded in, like a tire. Super strong, and won't rip, ever! I installed a set on my Eagle, and two years later, still look like new. I keep them soaked with armorall, along with the tires. Works fur me!
Bonny's # is 541-567-2833. |

...fwiw....
A close friend of mine is a diving instructor & I worked several cruises with diving photogs from Nat.Geographic.....they lived on silicone sprayed neoprene rubber from their masks to their regulators, after water washing, almost all their rubber items were shot w/silicone spray for continual rejuvination & preservation.
I, however have a desire to stay dry and out of the domain of plankton & have no such real experience....
However I wil fess to having a compartment hinge rubber fail in less than 9 mos with only morning sun exposure.
AND...
I am told and was raised on the belief that the ONLY good 2 lubricant-liquids to use on rubber are BRAKE FLUID & liquid soap |

When the hinges fail so rapidly there are usually only two causes.
1 the hinge groves must be straight , check with something.
2 the arms that hold the door up are binding and causing the door to rip off.
Simplest is to open & close the bay door a few times , sans attachments , and then keep opening & closing after each item is added.
You may find the sticky support arm , & can fix that.
With JOY or similar on instalation these hinges will last till the sun rots them off , & should go about a decade.
Ancient rubber hinge could be a cause , as could not using the handle in the center to open the door.

The one that failed me was on the "company" compartment F/R side, which is a short one AND was my 1st attempt at doing the change out.
I admit to doing a bit more "jiggling" than I thought would be necessary, I likely scored the flat area between the rounds which caused the failure....my 2nd attempt went much smoother and I am keeping a closer eye on it for deterioration, but also notice that, that particular comp.door is a bit tighter than all the rest in closing and might be stretching the rubber hinge beyond its comfortable abilities. |

There was some real junk hinge material sold over the years as "original equipment" quality. I was lucky to get two batches (from different sources) that hardly lasted a year each. I found the prop rod on one side of the large doors seemed to stress the cheap hinges at that end. This was much worse with the after market gas shock props.
The corded "Bison tuff" seems to be holding well. No problems in over two years. This product appears to be fabric reinforced belting material that has been machined to the "H" profile. BTW, "Da Book" says only use liquid soap to install, no petroleum product of any kind. Soap works great. A 25 caliber rifle cleaning rod and brass brush work great for cleaning out the grooves.

I would venture to say that you had poor quality or just plain old hinge material. I've used silicone on 3 busses now with no problems. Some of the hinges on my 4905 are well over 3 yrs old, installed with a heavy dose of silicone and no problems. Dish washing liquid does well also, but leaves a sticky residue unless rinsed off. Due to the stretchability, minor misalignment doesn't seem to be a contributing factor to failure. Just plain old dry rot and embrittlement from age. Fresh hinges are available direct from the manufacturer, Mohawk Mfg. at: 1-800-323-7652 ...JJ |

"that particular comp.door is a bit tighter than all the rest in closing and might be stretching the rubber hinge beyond its comfortable abilities. "
The tightness of the door can be adjusted by loosening the lock handle closure.

Today the aluminum lower hinge 1/2 for the electricial control.J-Box panel surfaced at the same time that I was due to pull a steel framed vent box from the area where the Lav used to be.
Once the framed box was de-rivited from the exterior aluminum skin and the steel frame behind and the area wire brushed clean I installed the aluminum hinge section and slid the new rubber joint into the upper 1/2 first (dry) and then proceeded to wipe the lower part with a cloth soaked with liquid soap & water...and sild the door on like I did it for a living.
fit is good, no stretch...and I was careful not to nick or scrape the rubber. It on the same side as the one that I lost early so the sun exposure will be equal.
Rubber is supple and fresh looking & very pliable like you would expect it to be.
Hosed off the rubber after install on both sides to clean it of residule soap.
I don't think I missed a trick & did a TT install so it will be interesting to see how long before I am doing the same job again on that door.....my feeling is that I'll be making the failure update in about november.
Maybe its all the air pollution coming from the commercial bread bakery next door....I know them onion rolls they bake every day about 5pm have a definite affect on me....... |
