So what is the Rotten Green Switch, and what does it do? The RGS is An electrical stress swap, which controls the hydraulic strain equipped for the actuator. It truly is intended to activate the pump at pressures beneath 1200 psi, and switch the pump off once the strain reaches 1600 psi.
Hook your significant tension hose again up to the back with the actuator, refill the reservoir once again, and you need to be fantastic to go.
Inside the decreased photo, with no hydraulic strain inside the cylinder, the piston/shaft will move each of the way to the correct. (For needs of the illustration, ignore the smaller degree of fluid proven before the piston. In precise apply, the piston would “bottom out†When the actuator wasn't mechanically linked to the brake technique).
Be encouraged that there are numerous distinctive “morphs†or versions of the program and components, however the diagrams exhibit the fundamentals which can be frequent to all of the AutoParks crafted from about 1989 thru existing.
Would be the J71 AutoPark parking brake procedure a nightmare to suit your needs? – It doesn’t must be and we can help.
We’ll endeavor to existing them within an approximately alphabetic buy. Feel free to send out us additions that you feel may be valuable.
Most actuators Use a manufacturing facility placard of some kind on them, which points out the Hazard (possibly appreciable) of opening up spring loaded actuators. It can be quite perilous and should not be undertaken with out some Functioning expertise in these gadgets.
So – – if you evaluate a Visit THIS Site picture from the actuator shaft Using the brake utilized, the amount of Place the thing is concerning the jam nut plus the actuator bracket encounter DOES Rely upon the star wheel adjustment, And also the issue of the brake shoes. This is exactly why worn shoes and/or insufficient adjustment will produce around-journey.
So through the years, we’ve type of consistently revised our attitude about autopark. What it boils all the way down to is this:
These relays do usually toast – – with time. Particularly when the system has taken the punishment most commonly occasioned by failure of your RGS (Rotten Environmentally friendly Switch). Once the RGS shorts “ON,†the relay can be subject to long durations of operation which are sure to deteriorate the contacts less than hefty recent load.
The preceding illustration exhibits the various combos your Genie Lamps may well Exhibit. Some are typical, some are more of a challenge, and some are serious more than enough to call for fast interest.
The purpose of this entire work out, is to indicate you need to have superior brake footwear and excellent cables, all adequately adjusted, for a prerequisite to any productive repair of your AutoPark parking brake process.
It should be emphasized that in most cases an actuator cylinder seal leak is a thing that starts smaller and grows. At some time, it Needs to be handled, but it is not ordinarily something that occurs fast and brings about fast highway failure or lockup with the parking brake.
Recently we’ve witnessed a large boost in the reports of J71 AutoPark leaking actuator cylinders. For several years, this malfunction has actually been Pretty much unheard of, but in the final 6 or 8 months They are really showing up with disturbing regularity.
