slide shear pin

Another broken shear pin. This time it is the rear street side slide pin. Does anyone know how to access the motor area? It is located behind the propane tank. All responses are much appreciated.............Logan.....07Inspire52000

I had repetitive slide bold failure with powergear shaft until I ordered the correct bolts from powergear. After I replaced I had no more problems.

I agree with other posters that the proper shear pins are required for longer life. I was not clear if you had used non stock shear pins when you replaced them before? Kevin Waite is where I got my shear pins, and I carry spares. (Knock on wood, have never had a shear pin break - yet:)!

I'm not real up on the Inspire, so this may be different with your coach, but a few best practices that members of this board passed onto me when I was new to CC and slides:)!

1) Crack a window or door when opening and closing the slides. (Reduces drag when opening, and compression when closing.

2) I was taught to count to five when done moving in or out. Some magic about self adjusting/syncing of both motors and drives, to keep them in alignment working together.

Those were the key things for day to day usage.

Other comments:

- Check and maintain fluid levels in the system - Check when closed, for good fit of the slide into the opening. If it is off, this can add strain to the system, and strain could add to pin shear - We always open/close our slides with the engine running, to be sure that adequate power is available to the motor drives. (Some don't worry about this, and even run the slides off of the inverters. I suppose full power from 50Amp hook up, would probably be OK too.)

If you have any concern about alignment being off, or motors not working in sync - get it in and get it serviced by a reputable shop.

All of these are just opinions, and what I have picked up from others on this board. But, reading the manual for full rules on the slides for your specific coach, is always the way to go.

Best of luck, and if you find you had a problem with the slides, please update so that we can all learn from it, Smitty

I agree mostly with Smitty with the exception to holding for the count of five. Hydraulic slides do like to be pressurized to help with the equalization cylinder but with the power gear rack and pinion there is no limit switch so the system just dead-heads. One should be very carful when extending and stop the moment movement stops. There is nothing to be gained with holding the switch down except shearing pins. At least that's the way it was on the 05 inspire I owned.

IMHO....You have to find the "Root Cause"....What's causing the shear pin to break? If you are using a #10 hard pin, then the likely cause is that the hole in the shaft is "wallowed out"! In such a case, each time the powerful motor turns the shaft, extreme leverage is placed on the pin bending it. You may have to ask power gear to make a new shaft for you to properly solve the problem.
My advice.....find a good tech before you end up damaging your slide walls.

Don't know about the shear pin but I keep the drop down area clean, pull up the edge of the carpet on the slide and vacuum then use a Spray Silicone Lubricant on the plastic plus I removed the 4 bolts one at a time that holds the motor in place and put Blue Loctite on them because they are ready to fall out.

I have had problems with the shear pin breaking and not allowing the slide to come in or out. Kevin solved the problem. He drilled out the the area where the pin goes in and placed a perfectly machined bolt. This does not allow for any movement. I have not had a problem since Kevin addressed the issue. We are very fortunate to have someone like Kevin to solve our CC problems.

I can't agree more with Floyd in making sure the motor in secure. The bolts go through the bulkhead and are subject to getting loose. This allows excessive movement of the motor and will cause the pins to shear. The proper shear pins are also very important. I speak from experience.

Thanks Rod - I've added to my learning curve:)!

I will add the one thing I should have noted to also reduce undue strain - I also was taught to level the coach first... (Though reading other boards with no CC owners, some say to put out slide, and then level... So not always the same over all mfg's.).

Smitty,

Practical experience makes me want to vote in favor of leveling first. I had two windshields split across the middle due to the coach being off level and having put out the slides anyway. It was the best I could do in a very un-level site. The problem was that the site was off level side to side. The coach can be off level front to back with little consequence except walking up or down hill all night. Side to side however is a different issue as it can tend to torque the frame depending how much further out of level the front wheels are with respect to the rear wheels. In my case I could not level the coach side to side so I got it as close as I could and proceeded to extend the slides anyway. It didn't happen immediately but rather about 5 minutes after setting up. Standing in the coach talking to my wife the windshield split down the middle right before our eyes. it was a sickening sound. I should have know when I found that I could not open most of the bay doors due to the distortion. On the other occasion the coach had been sitting in my daughters driveway for several weeks. I had leveled the coach when I put it there but the slides were not extended. One day day I visited the coach to get something and noticed it had drifted off level by quite a lot. I activated the HWH auto-leveling and was sitting there waiting for it to come back to level when the windshield suddenly split across the upper right corner on the drivers side.
So after a hard learned lesson I became very sensitive to sites that are obviously off level side to side. Most sites by the way are off level front to back it seems. In the last few years of owning a coach I would not even drive onto a site that was clearly off level side to side. if I could not see that it was off level then I would never extend the slides unless it could achieve side to side leveling. As I mentioned front to back did not worry me. So I always advise leveling first before extending the slides. Give it much thought from a physical perspective and it makes sense. I can not off hand think of any argument against it other than you might have to re-level a bit once the slides are extended. Small price to pay considering the possible consequence of doing it the other way.
According to the last research I did on the subject, todays gas absorption refrigerators can operate ok as long as they are not more than 6 degrees out of level.

If you have jacks, you should extend slides first and retract last. So it would go like this, locate on space, set parking brake, extend slides, level.
If you have air leveling you should extend slides first, but it is not as critical.
The logic being with air bags the chassis is not in stress, it may not be level, but it is not twisted. When you extend the jacks you can distort the chassis thus making the slide cutouts something other than square. A good example is the bay doors being difficult to open.

Mikee,

My coach had air bag leveling. In your opinion then what made my windshield crack and my bay door stuck closed on a site that I could not achieve side to side level and extended the slides? Once it cracked and the slides were not out at all.

I certainly have to agree with you on extending the slides first if you have jacks. I tend to forget about that because CC didn't use them very often in later years. Smitty's coach also has air bag leveling.

I have always leveled the coach first, and then put out the slides. But your point of twisting the body after leveling makes sense. If I put the slides out first then level, my concern is the jerking up and down to attain level doing damage to the slide.

Hi Don, Mikee,

Don knows my coach well, probably better tha I do yet - as he had a 'few' more years of using the same model then I have.

I will second that in some less than ideal leveled areas, even after leveling, I've seen what I would call stress on the body itself. Basement doors being tough to open, is a sure sign that not all is stress free:)!. When this happens, it seems to me that the front passenger side is the lowest side on the ground, needing the highest air bag height compensation to get to or near level. I have one place I park when washing the rig, that I have two 2x10 boards that I run the front passenger tire up on, to help out on this.

When I mentioned that other mfg's may recommend different processes on leveling Slide out Last in some cases. This was from talking with other mfg coach owners, and a long thread on RV.Net Class A forum about three years ago.

I know that Mikee has some RV smarts, so please add more info for us if it's appropriate.

Best to all,
Smitty

It will cause more damage by distorting the slide hole in the body, like trying to put a square object thru a non square hole.

My procedure is to level first to make sure the site will level then extend the slides. The HWH will Not extend unless the coach is within limits for extension. 06 intrigue 12047. Bob

On a fair amount of coaches it the coach is not in ride height the slides will not deploy or retract. The slides look for the ride height mode to allow operation. All Prevosts are this way as well as some others I know of.

Mikee.


CC manual for Power Gear jack states Level First. Extend slide. and if you want relevel coach. I do this on occasion but then I use the manual leveling part for the system.

No argument. It is your coach do what makes you comfortable.
Extend first seems to be more of a norm than the other way. I do not think Powergear makes chassis or understands the flexing involved.
Not trying to start an argument, but /i have never heard of a slide issue extending first.

Hi all

On my inspire with hydraulic powergear jacks I always leveled first. When I put slides out without jacks it felt like there was I little leaning perhaps not being taken up when on air bags so I would do half one side the half the other until out. The powergear operators also said to level first. On the magna country coach told me to put slides out then press the level button. Their theory was to level after the weight had been distributed since it would be different once the slides are out. Been working so far.

Mikee,

Sorry but I think you have made an error. You must level first before extending the slides! My coach at least has an interlock that will not allow the slides out unless the coach is level!

I am aware CC used this method on several models, however from experience repairing coaches this does not always work out too well.

Coachs with a single front jack are more likely to twist the frame than an air bag system with Two front bags. My coach with HWH leveling will not allow the slide pump to turn on unless The coach is level 06 intrigue. 12047. Bob
