Significant Observe: This legend goes using a modified drawing of your parking brake drum and connected areas. The original drawing lifted from the guide, mistakenly demonstrates the areas inverted – – Along with the star wheel adjuster at The underside on the backing plate in lieu of at the very best where it is actually Positioned. This new legend as well as modified drawing reflect what you need to see if you take aside the parking brake assembly.
This depicts an conclusion cap for the valve assembly when truly there is one thing pretty various in this place. The system over this position features the coil, and a sealed tube which includes the slug that is certainly forced downward when present is applied to the coil.
The following demonstrates some diagrams and supporting details on just what the brake assembly seems like:
Pull the female connector off the Light Swap and check for voltage involving the terminals and floor – – Just one terminal really should be incredibly hot, and a person chilly – – You want to tap to the cold just one.
Mainly while, the pumps and motors from Parker/Oildyne, are just about bulletproof. There are some pumps available made by MTE – – They appear very distinctive through the Oildyne, so are pretty effortlessly determined by comparing shots.
These relays do are inclined to toast – – eventually. Particularly when the method has taken the punishment most often occasioned by failure on the RGS (Rotten Environmentally friendly Change). If the RGS shorts “ON,” the relay can be subject matter to long intervals of operation that are bound to deteriorate the contacts under hefty latest load.
This concludes the relay and motor testing treatment. When you've got determined by leaping the connector Using the U formed jumper that the motor runs, and also have changed the relay as well as motor Would not operate, then there is a dilemma Using the control circuit. Let us know and we’ll work thru that problem being a independent training.
Moreover, You will find a lever arm in series Together with the cable technique for AutoPark, and as a result of configuration of the lever arm, once the actuator moves one.25 inches, the cable visiting the brake drum might only transfer about an inch.
Once you have taken out the 4 nuts from their studs, and you've got disconnected the incoming line, it is possible to simply pull the cylinder off in the studs.
This is rather easy – – This first image exhibits the required wrenches and placement for disconnecting the incoming hydraulic line (the actuator is with a bench prime exam stand).
Issues: All different variations of AutoPark have their unique peculiarities and tendencies to fail. We won’t go into all of that here – – Suffice to convey they do are unsuccessful, and usually inside of a fashion that locks up the parking brake – – From the rapidly lane, your driveway, where ever.
Transfer shift selector outside of PARK. If AutoPark lite goes on and STAYS on, you could possibly pretty very likely Possess a negative RGS. A good RGS would Typically run the pump As well as AutoPark lite for any about three to five seconds after which end – – The lite would head out in the event the pump stops.
As it turns out, the lubrication procedure can be attained and not using a great deal of preparing work. Whilst somewhat awkward, the swap might visit be reached by laying in front of the still left entrance wheel, and achieving up towards the swap.
This document is a compilation of a number of individual write-ups. What we’re looking to do here is consolidate the required details required so that you can make an enough shoe adjustment (or shoe substitution) in your AutoPark parking brake assembly.
