The down below pair of images on the following webpage that assistance to explain the above dilemma. In the image below, it is vital to note the shiny hex adapter is made of quite tender content, and it is really straightforward to strip the threads by about tightening the RGS when threading it to the adapter.
In combination with the actuator process and that is illustrated and described previously mentioned, the newer units Have got a superior stress hydraulic pump that is definitely motor driven and controlled by a combination of electronic and hydraulic units.
If the RGS fails while in the locked ON situation, the AutoPark lite over the sprint will keep ON as the pump proceeds to run (or attempts
This image should help most coach homeowners discover several parts of their AutoPark parking brake program.
It is a minimal button valve. It is actually captured in placement but can “float†in the up and down route. It pretty of course can avert movement backwards up into the valve bodies, but precisely what that accomplishes, I have nonetheless to determine. It opens straight in to the exit line going to the reservoir, which is rarely stressed aside from atmospheric.
The picture on the left exhibits the goodie-box as becoming fairly messy – – the result of a leaking Rotten Environmentally friendly Swap. The duvet plate has to be eliminated to access the AutoPark factors.
About 95 % of all autopark repairs are things that most any decent shadetree DIY mechanic can perform for himself.
 Should you have had a leaking actuator and also have had us (or someone else) repair it, check this out there is a pretty higher likelihood which the method has lots of contamination and crud in it.
Barring one of many two over situations, the lining from the parking brake really should final indefinitely. A uncommon exception will be if the rear seal inside the transmission leaks, and soaks the brake shoes with ATF. This will require alternative in the shoes regardless of their dress in condition.
Issue E. – – Your AutoPark pump is operating frequently, or a minimum of wanting to operate regularly – It could be stalling. This is actually the standard indicator of very first phase RGS failure. Given that the Purple lite hasn't long gone ON, you still have system strain Keeping the parking brake in a Introduced condition.
For the reason that Edition II as well as Variation III Every have a little distinct wiring diagrams, we will clearly show the modified block diagram for both.
Hook your superior strain hose back again up to your back again in the actuator, refill the reservoir again, and you ought to be fantastic to go.
Although we’re persuaded that age is the key perpetrator, we also know there are numerous situations in which brake fluid instead of ATF is put to the AutoPark reservoir. Brake fluid is EXTREMELY DISTRUCTIVE to many of the rubber and polymer items that are normally located in methods made for ATF (automatic transmission fluid).
Recently we’ve seen a large boost in the stories of J71 AutoPark leaking actuator cylinders. For a long time, this malfunction has been Practically unheard of, but in the last 6 or eight months they are appearing with disturbing regularity.
