Using an external air compressor on an old Loadstar 1700.

If I read that correctly…..

Can you just take a 5/16 wrench and adjust your brakes till they back off ?

 

Remove discharge pipe from on top of air compressor and plumb your air source into this hose or pipe. If it’s old it prolly a copper tube coming off of the air compressor and possible a #10 size female fittting you will need to plumb into on the hose going to the air tanks on the truck
You can add an in line valve if you wish but the check valves in the tanks should hold the air. If nothing else do,this long enough to release the brakes if,they will and adjust them off in the event you have a killer air leak some where.

 

The governor on the compressor probably has an unused port with a 1/4 inch plug in it.
Take it out and install a standard schrader valve.

 

Just take whole brake chamber off by taking the two nuts off the bracket that holds it on, and knock the pin out, and let it ride straped on till you get it running and buy a new brake chamber?

 

Leave the air system intact and just pull a plug out of an air tank and install a “P” type air coupler in hole. Hook up external shop air hose and slowly let air flow in. The coupler will allow the hose to be disconnected and leave system aired up.

 

this is what i’ve done to the ‘65 White I’m working on now. I can air up the system with shop air. I can check for leaks, Release brakes, Use brake pedal and run anything that requires air without starting and running the engine. Works great for cold starts in the shop. I don’t have to wait 5 mins for compressor to air system to move truck outside while shop fills up with smoke.

 

Yeah just put some fittings in the air tanks. Might have to air up more than one tank depending how it's setup.

We had a running truck with bad compressor. Put gas powered compressor on cat walk and drove it 20 miles to the shop.

It's handy to have air fittings on tanks anyway

 

Can this cause the truck to roll backwards even if you have pulled the brakes.

 

No
