Repairing The trouble: As stated earlier mentioned, we’ve begun to are convinced the lubrication can be far more vital compared to adjustment. For the reason that lubrication system necessitates no disassembly it is the much easier process of the two.
Problem E. – – Your AutoPark pump is working continuously, or at the least wanting to operate frequently – It could be stalling. This can be the regular signal of initially stage RGS failure. So long as the RED lite has not absent ON, you still have technique tension holding the parking brake inside a Unveiled issue.
So – – Assuming the cables themselves are in excellent problem, this leaves our remaining variable to become the extended hex nut about the actuator shaft – – depicted as #1 from the illustration higher than. It is very important to notice that this actuator is shown during the BRAKE ON condition – – Try out TO VISUALIZE IT With all the SPRING COMPRESSED during the BRAKE OFF condition. Together with the brake OFF plus the actuator shaft extended to its mechanical Restrict, we would want to adjust the very long hex nut just to the point where by there was no slack during the cable procedure – – no extra, no considerably less. If we then get rid of the hydraulic strain from your actuator, the spring will broaden, plus the piston and shaft will shift to the proper – – applying the brake. Which means the brake lever from the drum will move about an inch, the cable going to the lever relay will go regarding the exact inch, the cable going Through the relay towards the actuator will go about 1.
In several scenarios, straightforward replacement of your RGS will solve all the issues along with the process will once more operate in a standard fashion. Often tho, the thermal protector from the motor will likely have failed due to the repeated cycles of abuse.
The above more or less describes a normal RGS failure. BUT, occasionally (possibly in 10 percent from the failures) the program will exhibit a pretty unique list of failure symptoms. We phone this “the stalled pump syndrome.†In these conditions, the AutoPark lite around the sprint goes ON and stays on, although the pump Visit This Website might be heard to generally be cycling – – Probably managing for 30 seconds, then stopping for 2 or 3 minutes, then running for thirty seconds etcetera.
Prior to we get in to the particulars with the elements, or analysis and repair, it may well help to obtain some basic knowledge of how AutoPark functions. The next illustration describes the process in rather basic conditions. We recommend learning these diagrams and textual content, so as in order to visualize what your AutoPark is undertaking when you implement, or launch the parking brake.
In the subsequent PDF We're going to attempt to aid the coach owner know that your AutoPark parking brake adjuster and star-wheel Can't be accessed thru a port in the backing plate just like the previous spouse and children vehicle used to be configured.
So – – Bottom line: We advise folks to find out about their AutoPark. Almost nearly anything that goes Completely wrong with it, is one area you can deal with you If you're OK with a few uncomplicated mechanical do the job.
three. You will discover truck retailers and these Which may be willing to get rid of the leaking actuator or cylinder and possibly repair it or mail it out for repair. Pretty probably in a cost savings about option 2 – –
Ordinarily, in the event the gear shift lever is moved from PARK to Various other posture (reverse, travel, neutral), the RGS will switch the pump on until the process force reaches 1600 psi and then the RGS will Visit the open Get hold of affliction, and shut the pump off.
A very good electrical motor shop can typically replace the protector for significantly less than the cost of an entire new motor – – a little something to take into account if this type of shop is inside of a reasonable length.
About the still left is an image of a completely new Rotten Inexperienced Swap – – as pointed out elsewhere, it is sometimes brown in coloration, however the function is unchanged irrespective of whether it really is brown or green.
Hook your significant force hose back again up into the again in the actuator, refill the reservoir again, and you have to be excellent to go.
Any deviation from the above mentioned description, will probably point out some type of challenge Together with the AutoPark method. Don’t despair however. We are able to change the web pages Whilst you convert the wrenches – – and in between us, we’ll get it mounted.
