Some cylinders on newer coaches may have an around travel switch screwed to the flange over the cylinder such as just one shown in the above photograph.
So – – Around the RGS woman connector, the terminal you need are available by turning to the ignition, (don’t start out motor), pull the shift lever Away from PARK TO REVERSE, and examining for voltage involving ground, and at each of the two terminals.
Most of the subsequent is stuff Now we have lifted from manuals and these – – There'll quite probably be some duplications of content between the different write-ups.
Kind III technique – – Uncovered on chassis manufactured concerning (approx) mid 1998 and 2007. Comparable to Sort II but lacks the handbook foot pedal for software in the parking brake. Contains a yellow force-pull knob on the dashboard.
Poppet Valve – – A A method valve which is located in the fitting slightly below the RGS. It is well and infrequently dropped when getting rid of the hex retainer that keeps it in place.
Revised is The crucial element word below. We've been observing an impressive upswing in the quantity of situation switch difficulties introduced to our interest. This has led us to consider a more in-depth think about the technique, and also to update our considering and share our conclusions In this particular doc.
We have been hoping that The supply of this package will serve to advertise the set up of the Genie Lamp on each mentor that is provided While using the J71 AutoPark technique.
A “companion†compose up that goes coupled with this just one that you are examining, is titled “How It really works.†In that write up, There's a picture (with annotations) of an AutoPark parking brake with the drum eradicated. You are able to begin to see the shoes, levers, springs and so on. Possessing that publish up in front of you as you read this
Pull the female connector off The sunshine Change and check for voltage amongst the terminals and ground – – One particular terminal must be incredibly hot, and one cold – – You want to tap to the chilly one.
That is a little button valve. It truly is captured in situation but can “float†while in learn more the up and down direction. It quite clearly can prevent move backwards up into the valve bodies, but exactly what that accomplishes, I've but to figure out. It opens straight in the exit line visiting the reservoir, which isn't under pressure other than atmospheric.
Explanation: Each of the GM literature says you don’t dare Focus on these actuators mainly because the spring in them is extremely robust, and if you choose them aside issues may perhaps fly all over hell and injure an individual. Correct enough in case you don’t know what you are executing. BUT, Here's what you are able to do – – It is possible to compress that spring and cage it (continue to keep it compressed) Before you decide to go ahead and take actuator apart. This really is accomplished by just turning that #3 nut to the right, up towards the actuator housing, right up until you might have the spring compressed – – by advantage on the nut pulling the shaft to your left.
The fix for This is often to interchange the sneakers If they're poorly plenty of worn – – If you still have sufficient lining, you might take up the slack with the star wheel adjuster.
Along with the ignition ON (don’t start out motor) and change lever in REVERSE, – – both of Those people strain swap (the gray Lite Swap and also the environmentally friendly or brown pump motor switch [RGS RBS] ) connectors may have 1 in their two terminals with 12 volts existing. However, you want the terminal that is definitely switched – – not the one that is incredibly hot all the time.
IMPORTANT Observe: This legend goes having a modified drawing from the parking brake drum and involved pieces. The first drawing lifted from your manual, mistakenly reveals the areas inverted – – Together with the star wheel adjuster at the BOTTOM from the backing plate in lieu of at the TOP where it is actually Found. This new legend as well as the modified drawing reflect what you must find out if you are taking aside the parking brake assembly.
