DIY? N14 air compressor & oil pump

Hello & hello. I've heard that the coolant needs to be drained, and that a special 5/8 span wrench will be needed. Any other useful tips? This will put my skills to the test and will probably be the "biggest" job I've done myself. The savings would be about $1100 in labor. ----Is there a special type of thread sealant to use when putting bolts back in? Will bolts break coming off? ( I found Kroil oil for seized bolts and got some) ____this job looks like there will be some cussin' and Knuckle bustin'

The air compressor is passing a little oil but not enough to notice when draining the air tanks. There's no oil in the intake side, output only. The oil pump is leaking where the power steering meets & where the pick up tube meets the oil pump. Bot work really good, the air builds good, and oil pressure is fine... Don't really want to replace them but I figured now might be a good time since oil is starting to get through the compressor and they are both orginal at about 900k on them...

Any thoughts or opinions on this matter? Thanks in advance, safe trails.

 

10-4 thanks... By supports you mean?... The walls inside the tube maybe?

Do you know if the pick up tube, the side attatched to the pump, can be serviced? That's where mine needs to be serviced...

 

I've finally decided to take on the oil pump at least while I already have my power steering pump off.

Would you recommend painting the oil pump and the power steering pump first? The new transfer tube I have is painted red all ready, which is fine. But I'm concerned if I don't paint the pumps that they'll rust over pretty quickly

Any thoughts or advice on this? Paint types, paint with a primer color first ...?

I have some of that Cummins red allready from the dealer

 

Does anybody know about when putting the power steering pump back on to the oil pump, what the "sleeve" looks like to connect the two gears & the right way to put in on / secure it?.

My local tech told me it was a sleeve and it probably fell off taking one of the pumps off.

I did find a cylinder shaped piece that fell out of the oil pump and I think it's it,,

But here's the picture of the pieces it's supposed to connect, folks who've done this before I know probably wouldn't need the picture

Thanks in advance
