Occasionally, anyone claims they don’t have an AutoPark Light-weight on their cluster, and investigation proves there is nothing within the printed circuit exactly where it ought to be. Additional investigation could show that the circuit was printed for Several other chassis – – often a diesel chassis where it'll show glow plugs or a thing like that. We could’t explain this or tell you why it's happened. It just comes about to get that way in some cases.
If it is de facto no cost to maneuver, you could hear it simply click after you tip the core back and forth within a teeter totter trend. If you're able to hear it click only with vigorous shaking, then it is still sticky. Soak it some additional, and shake it some far more.
This exhibits an finish look at of a spronged AutoPark brake actuator that was opened with out getting the spring sufficiently compressed. Another photograph that has a side check out shows what transpired. On this image, see how the actuator shaft is jammed about to 1 aspect of the opening. This may be perilous.
In the subsequent PDF We'll test that can help the mentor operator realize that your AutoPark parking brake adjuster and star-wheel Can't be accessed thru a port from the backing plate much like the outdated spouse and children vehicle used to be configured.
two. It really is remotely probable that the large fusible url (60 amps or so) that shields the relay and motor, could be blown. We’ve hardly ever seen this occur as still, but it surely must be viewed as. Just one could test for this very conveniently, by pulling the connector off on the relay, and checking with the existence of twelve volts on on the list of two massive  wires in the female connector.
If the above data is url raising some concerns for you, Be happy to Make contact with us for even more enlightenment. We've got various data sheets on this topic – – photographs and many others.
At the highest of the picture, the shoe finishes might be bearing over the adjuster, and can pivot on Individuals ends if the brake is used.
Also, There's a lever arm in collection Using the cable technique for AutoPark, and as a result of configuration of the lever arm, if the actuator moves one.twenty five inches, the cable going to the brake drum could only transfer about an inch.
Get beneath the rig and orient that port about the brake drum to 12 o’clock. Open the port and acquire it over the adjuster; Then, click on the adjuster right until you will get just the slightest drag.
You should let's know When you've got concerns or considerations regarding the higher than. We're going to handle them as very best as we can.
The subsequent image illustrates the AutoPark parking brake lever relay system with optional pedal brake which is observed only on coaches built amongst about mid ninety four to mid ninety eight.
Transfer bar (dunno what it can be adequately known as) moves on the left and transfers movement from place B to issue A pushing out the still left hand shoe
A more absolutely sure fire way of confirming the stall is to truly position a hand within the motor as it is cycling – – It is possible to usually hear/sense the motor trying to run even though it is actually stalled – – right up until the thermal protector visits.
It is a mounted, mechanical limitation. The huge spring is not going to compress any farther, Hence the actuator shaft as well can not go any farther..
