Air in oil line between Tank and Pump - How to fix?

[JJ_0909]

Just like the title says. Had a bit of an "ooops" when I was moving the oil tank out of my way for some work. (Pulled the fitting out of the tank)

Obviously, I need to get the 3" bubble of air out of the line. Being the pump is electric, I'm not sure how to bleed it.

You can pull the line off and top it off with a syringe or the dealer can prime the line with digital wrench. I guess you could also pull the line off at the pump, it just might be a little messy.

You can also power up the ECM PWR and DC PWR ports, hold the brake, perc, and throttle for 15 seconds. This will key the oil pump to run for 30 seconds.

Thanks.

I did purge as much of it w a syringe as possible. Woke up this AM and a smaller bubble by the tank. Filled tank half way, turned it sideways, and it seems the bubble migrated upward into the tank and out of the system.

It'd make sense that any air would end up at the top of the system right? Probably no need to cycle the oil pump at this point no?

Side note, for future reference, how do I do this "power up the ECM PWR and DC PWR ports"

Supply the connectors with 12VDC similar to setting your TPS.

Per the manual, this is to be done IF there is a bubble 1 inch or larger in the lines FROM the pump TO the crankcase.

To eliminate the bubble at the tank nipple, cover the primary with a rag, remove the hose clamp and slowly slide the hose of just enough to allow some oil & the air to drain out then install the hose & clamp. Bubble should be gone, if not do it again. This procedure has always worked for me.

This is the best and easiest way to do it.

Bubbles? Again?! WTF?!!

I haven't ridden my sled yet but saw a 1" bubble in the hose right at the tank. I don't know if it would hurt anything but got rid of it by tipping the sled on it's right side and squeezing the line a bit by the pump to burp it into the tank. The bubble wouldn't go into the tank on it's own even with the sled completely on it's side for an hour.
