Splitter stuck

Piece of mind for me is worth any amount of money.
example: Had a notice( not a recall) on my ISX fuel pump throwing ceramic pieces into the oil, leading to a junked engine. Spent the $4,000 and got the new one with the adapter for the lines. I probably got hosed, but the pump showed wear on the cylinders and I have a pump that won't trash my #4 main journal where the oil from the fuel pump goes back into.
All that equals piece of mind.

 

Some trucks have a regulator in primary tank functions won't work below 60 psi usually. I stress some not all. The transmission has a regulator as well. Most Eaton's default to high range with no air. Air puts them in low. There is a brass filter in the regulator that will give more trouble in the cold. Air Lines snap in the blink of an eye even if your careful. I will say I have had more luck in your situation pulling shift knob lines and letting the ice blow out. Alcohol or air line antifreeze is almost useless in front of the drier. You can pull the drier out let line or bleed the tanks all the way down, pull a plug out of the top pour it in that way, which gets you going faster. Nothing any more miserable than laying on the cold wet ### ground I agree. But how bad do you need to be trucking is the question

 

Sometimes its not moisture causing valve problems. Lots of times it is just cold making the rubber and seals hard and want to stick inside the valves.

If it’s just sticking because of cold, usually tapping on valve with a hammer or something will free it. Just don’t hit it hard enough to break it. Remember, the valve body is already cold and brittle.

 

Exactly. I've had them stick from being to dry in the dry southwest summer. A little WD40 or similar in the air shifter lines to get the orings lubricated,and the cylinders sliding again.

 

Never would I have thought to dry was an issue. But I'm not in the dessert.

 

Engine? Year?

 

Fan clutch needs adjust, or fan clutch air solenoid.

 

When the clutch goes it defaults to run all the time.
