Cab pump

Tip!

Here's how to get the air out of the system: Install the cab tubes, hoses and cab pump. Remove the level plug that is on the pump, push a hose that fits exactly into the hole. Make sure there is a tight fit between the hose and the hole. Put the hose in a can of automatic transmission oil. Drive the cab up and down, making sure there is always oil in the can. Now the cab pump sucks in the oil it needs and pushes out the air that bubbles up in the can. The oil foams a lot and mixes with air, now wait until the oil is clear and nice it may take a couple of hours. Then you run the cab up and down again, repeat this until the oil is clear and fine without air mixing. It can take a long time, but if you can wait between the cab up and down runs, it's easier and you'll get a good result. When everything seems Ok, wait a while and let the excess oil flow back to the can that you have lower than the cab pump, then you just remove the hose and put the level plug back on the pump which now has the correct level of oil. Note! only run the pump up and down max. 2 times then it has to rest for a while. It's easy to drive too much and burn the cab pump's electric motor. So take it easy and don't stress about this and it will be great.
Check that all the cables are in good condition all the way to the cab pump. If you are in doubt about the cables, you can mount a cable relay behind the cab pump. It is very important that the cab pump receives full amperage, otherwise it will be overloaded and burn up.
