THE PROBLEM: For quite a few a long time, we have been hearing about a difficulty that entails shifting from PARK to REVERSE – – In the event the change lever is moved from PARK, the AutoPark technique is designed to launch the parking brake, and allow the coach to roll. Having said that, it seems which the switching mechanism which makes this probable (generally known as the “the equipment shift lever placement switch”), does not often precisely feeling the shift lever placement.
As pointed out previously mentioned, Some programs even have a handbook implies of applying this brake – – and also the AutoPark. From about mid 98 on on the other hand, the only parking brake operate is furnished by the AutoPark – – No foot pedal or lever.
The above information and facts pertains towards the J71 AutoPark method utilised on coaches crafted from about mid 94 and afterwards. If you have certainly one of the sooner units that operates off of the power steering procedure, let me know. Which is a very different actuator. Additional unsafe to operate on.
Refill the AutoPark reservoir with new ATF and do it once again. One particular flush need to clean most systems, but when the thing is lots of residue during the reservoir, you must repeat the method until almost everything appears thoroughly clean.
Take away the relay from the socket/connector. Identify the two terminals within the connector which are fed by the two Significant wires.
Curiously, actuator repair turns out to generally be one of many only a few things that an operator may possibly need to have some outdoors assistance to perform. Even then, the majority of the repair procedure Is one area it is possible to participate in – – conserving about 90 percent of the common costs for this function.
As for the most beneficial location to tap the technique for that inexperienced Genie Lamp about the 98 and afterwards coaches, I feel the most effective place could be the incoming wire to the yellow pull switch on the dashboard. That should always have twelve volts coming to it If your ignition is ON.
Hook your substantial strain hose back up into the back again with the AutoPark actuator, refill the reservoir again, and you have to be great to go.
So – – Assuming the cables them selves are in superior affliction, this leaves our remaining variable to get the extended hex nut to the actuator shaft – – depicted as #one inside the illustration above. It is vital to note this actuator is proven from the BRAKE ON condition – – Check out To visualise IT While using the SPRING COMPRESSED from the BRAKE OFF problem. With all the brake OFF as well as actuator shaft prolonged to its mechanical limit, we'd want to adjust the very long hex nut just to The purpose in which there was no slack in the cable method – – no far more, no much less. If we then take away the hydraulic stress in the actuator, the spring will expand, plus the piston and shaft will transfer to the proper – – applying the brake. Which means that the brake lever during the drum will transfer about an inch, the cable visiting the lever relay will go concerning the very same inch, the cable (visit site) likely From your relay on the actuator will shift about 1.
This is a simple and low-priced (under 20 bucks in elements) unit that is made up of 3 tiny indicator lamps. Most any Do it yourself RV’er can Create and put in it without having issues.
Hook your large strain hose back up on the again with the actuator, refill the reservoir yet again, and you should be superior to go.
This, along with a insufficient readily available service (my feeling), has led many people to ask if they could disable the AutoPark and head over to some kind of fully manual program.
On all variations of AutoPark, there is actually a drum brake within the driveline – – appropriate guiding the tranny. Adjusting it can be much like carrying out the brakes on an older passenger motor vehicle.
