The pump will keep off until the tension has dropped to 1200 psi or decrease, after which you can it will eventually cycle plus the stress operates again approximately 1600 psi. This Hello tension is needed to Launch the parking brake Therefore the coach can roll.
Goody Box – – A steel box, Situated under the coach about the passenger facet frame rail – – just aft with the transmission. On chassis in between mid 1994 and mid 2001, it contains the actuator, the pump and reservoir, the pump motor relay, as well as the solenoid valve.
Pull the gear shift lever out of PARK. This should start off the AutoPark technique pump motor operating and it will immediately blow every one of the old ATF into your pop bottle.
The above facts pertains to the J71 AutoPark system utilised on coaches designed from about mid ninety four and later. When you have certainly one of the sooner units that runs off of the power steering process, let me know. That is certainly a very various actuator. Extra risky to operate on.
If there is Multiple inch of vacation at that point, you cannot properly compensate for it by modifying cable changes or Various other parameter while in the method.
This illustration demonstrates how the configuration on the crimson lever has an effect on the cable movement. The geometry of the set up is these that When the blue cable moves about an inch, the red cable will shift about an inch and 1 / 4. This is very important to remember in almost any dialogue of actuator journey.
So I figure about ninety pounds full for elements, transport, and labor – – This will work out to about 65 dollars to the repair moreover some time packing for cargo and jogging on the Put up Office. If This really is greater than it is possible to find the money for, mail what ever is effective for yourself – – no massive deal.
A far more certain fire technique for confirming the stall is to truly position a hand on the motor as it can be biking – – You could normally hear/truly feel the motor wanting to run although it really is stalled – – until the thermal protector journeys.
So when lever is pulled to left by Check THIS SITE Out cable, sneakers will spread. Place concerning them beneath the retainer (at the bottom) can get broader. Funny formed washer retains the shoe ends set up.
Under typical circumstances, once the strain is removed plus the spring expands, the piston vacation is limited from the cable drawing limited because the brake footwear tighten versus the drum. So Should the sneakers are terribly worn, or the cables also loose, the piston will journey farther than it will normally.
one. If you can’t fairly get to the switch, you could just take a small paint brush and duct tape it into a stick – – supplying the required extra arrive at. Get the brush liberally smeared up that has a sticky grease like LubriPlate.
Refill the AutoPark reservoir with fresh new ATF and get it done yet again. One flush ought to cleanse most techniques, but if you see a lot of residue within the reservoir, it is best to repeat the procedure until everything looks clean.
Due to the earlier mentioned said considerations, it is absolutely critical which the slack/rigidity adjustment within the cable procedure involving the actuator and the sneakers,
The incredibly superior tension in some unspecified time in the future ruptures the switch, and oil starts off trickling out earlier the change terminals. Inevitably, all of the oil will leak out and the actuator will use the parking brake for insufficient hydraulic tension.
