Thank You.

Hello, can anyone give me the torque specs for rod bolts and cylinder head bolts foe 1986 em6-285. would be greatly appreciated.

also keeping my eyes and ears open for another motor.. Thank Craig..

Hmm ok so the switch should have two terminals on one side for the wires and the other side is threaded into one of the foot valve ports. I would buy another switch and just replace it. Just unhook the two wires and unscrew the switch and screw the new one in and hook the wires back up.

If you have any more questions don't hesitate to ask.

YES thats the switch. Truck has no JAKE. Its a new switch now.. Question is --was is it activated by air? or does something physicly (solid) open the switch. I didn't switch part employee did, if not air triggered did he lose a part? could mack have sold mE a switch (if air activated) of the wrong pressure requirment to open? If as was posted previously- air-pressure opens it and it only opens under heavy braking. its to heavy a switch.. Hate to over analise this dealer is hour away, maybe NAPA WILL HAVE REPLACEMENT.

On all trucks equiped with air brakes the brake lights come on with a switch that is turned on by the air pressure. Are you sure its mounted to your brake pedal?

mounted on PEDAL VALVE. If all are brake- air pressure activated- the switch is requiring to much pressure to activate?

Hello all, have a problem with brake lights. they only come on if you step harder on brakes than you usualy will.. recient switch replacement done my driver not employed any more, truck is 1985 mr 688 switch is on pedal valve. what is likely cause. switch screws in so no rod to adjust.. does air pressure engage switch? THANKS
