The above info pertains to your J71 AutoPark system utilised on coaches built from about mid ninety four and later on. Should you have among the sooner units that runs off of the ability steering technique, allow me to know. That may be a very distinctive actuator. A lot more risky to operate on.
For anyone who is so inclined, the seriously Great way to go is to make and set up the Genie Lamp procedure. If you'd like info on this, or any of the above, remember to email oldusedbear
Issues Using the Handle circuit, are usually not the main target of the particular writeup. The reason listed here, is always to possibly discover, or absolve the relay as the reason the pump won't operate.
two. It truly is remotely attainable that the big fusible link (60 amps or so) that shields the relay and motor, may very well be blown. We’ve under no circumstances found this transpire as nonetheless, but it should be regarded. One particular could take a look at for this rather easily, by pulling the connector off in the relay, and checking for that existence of 12 volts on one of several two huge  wires in the feminine connector.
So – – Assuming the cables themselves are in superior condition, this leaves our remaining variable to generally be the extended hex nut about the actuator shaft – – depicted as #one within the illustration over. It is critical to notice that this actuator is proven while in the BRAKE ON issue – – Try out To visualise IT Using the SPRING COMPRESSED within the BRAKE OFF problem. Together with the brake OFF as well as actuator shaft extended to its mechanical Restrict, we would want to adjust the extended hex nut just to The purpose the place there was no slack within the cable method – – no much more, no much less. If we then remove the hydraulic strain within the actuator, the spring will grow, along with the piston and shaft will shift to the right – – implementing the brake. Consequently the brake lever from the drum will shift about an inch, the cable visiting the lever relay will go about the similar inch, the cable going In the relay for the actuator will shift about 1.
This offer is made up of text, circuits and diagrams that describe an auxiliary dashboard warning light-weight technique. It operates independently of, and in addition to the normal AutoPark sprint light.
THIS Is vital: Together with the actuator cylinder eliminated, plus the incoming line disconnected, your parking brake will be Used. It will continue to keep the coach from rolling – – so have it parked where you want it Prior to deciding to make this happen do the job.
When you have a leaking J71 AutoPark parking brake actuator, OR you're anxious the actuator cylinder seal may possibly fail on account of age or contaminated process fluid, then you should be mindful of some of your readily available repair possibilities:
The brake evaluation Charge is credited in direction of any brake repairs if you end up picking to contain the do the job accomplished
This document is really a compilation of quite a few different generate-ups. What we’re wanting to do Here's consolidate the mandatory information and facts wanted that you should make an suitable shoe adjustment (or shoe substitution) on your AutoPark parking brake assembly.
I don’t have the section figures for your O rings, but a good vehicle parts spot like NAPA needs to be in a position to assist you with that. Or, you could go directly to Haldex (the maker of your actuator) on the internet and order them like that.
Interestingly tho, this switch has no impact on anything at all else while in the procedure. Whether or not it works or not, it essentially has no impact on the driveability of the mentor. The exception to This is often In the event the switch develops a short to ground – – in which case it is going to blow the AutoPark fuse and you WILL obtain a brake lockup. The shorts are rather rare tho – – Luckily.
Currently we’ve noticed an enormous increase in the studies of J71 AutoPark leaking actuator cylinders. For a long time, this malfunction Have A Peek At This Website has long been Practically unheard of, but in the last six or 8 months They may be popping up with disturbing regularity.
This is a simple and low-priced (lower than twenty bucks in components) machine that is made up of a few compact indicator lamps. Most any Do-it-yourself RV’er can Establish and put in it with no problem.
