Apparently, each of the AutoParks designed from 1989 up thru about 1994, have been pushed by force from the facility steering pump in place of the independent electrical pump that characterizes all of the later on units.
Given that this full mechanism will not be RIGIDLY fastened into the backing plate, it type of “floats†and is particularly self centering – – So equivalent pressure is applied to each the left hand and the proper hand footwear.
This depicts an end cap with the valve assembly when actually there is something very diverse in this place. The mechanism earlier mentioned this place features the coil, and also a sealed tube which contains the slug that is certainly pressured downward when present-day is applied to the coil.
The under pair of pictures on the subsequent web site that support to explain the above mentioned problem. In the picture under, it's important to notice that the shiny hex adapter is made of extremely comfortable product, and it's pretty simple to strip the threads by above tightening the RGS when threading it into the adapter.
2. The RGS has long gone bad and has turned on the pump As well as AutoPark light. Stress will go thru the roof and soon rupture the RGS or A few other part. Then, the brake will automatically implement.
The above mentioned roughly describes an average RGS failure. BUT, occasionally (maybe in 10 per cent from the failures) the system will exhibit a fairly distinct set of failure indications. We call this “the stalled pump syndrome.†In these situations, the AutoPark lite within the dash goes ON and stays on, however the pump is usually read to be biking – – Most likely managing for thirty seconds, then stopping for two or three minutes, then operating for 30 seconds and so on.
This is actually the change soon after removal. When your cylinder has a switch such as this, you should get it off prior to transport the cylinder. This calls for an eleven/sixteen inch open conclude wrench.
In the following PDF publish-up, We're going to do our best to explain The entire AutoPark brake setup and its operation is not something you can certainly comprehend at a look. They intended this floating idea to help keep the shoes type of self centering from the drum.
This doc is often a compilation of several individual compose-ups. What we’re attempting to do here is consolidate the mandatory information needed so that you can make an adequate shoe adjustment (or shoe substitution) on your AutoPark parking brake assembly.
When the leak is not really much too huge, the pump can keep forward of it and maintain the brake from locking up – – but your pump is functioning extra time to create this occur.
The earlier versions of AutoPark (from ninety four Check Out THIS SITE around about mid 1001) possess the pump and the majority of the other goodies underneath the coach, but the later variations don't.
The subsequent writeups and pics are actually packaged to deal with the analysis and if required, the alternative of the failed Rotten Inexperienced Switch – – aka the pump motor switch or RGS. Considering the fact that these memos were being penned to ship out separately generally, there may be some duplication in articles.
As outlined earlier, This really is Among the most monotonous processes a person will come upon in AutoPark repair. It is actually under no circumstances unusual to have to repeat a few of the bleeds greater than the moment.
be marginally extra or somewhat fewer, but massive deviations will most likely reveal a system that's possibly as well restricted, or far too loose.
