Thanks Colt! I'm working on this right now.

Do you have a source for the brass right angle and the adapter on the short hose? I can find the part numbers in the TM's, but I can't seem to find the actual parts for sale on-line.

I have been trying to source parts for a while. From what I can gather, talking to axle shops, is in order to really get parts from Dana/Spicer, you need to set yourself up as a distributor. And as one, you need to meet minimums as far as purchases.

I've considered doing it & becoming the "source" for CTIS stuff. But, I have the feeling it's a big investment. I don't want thousands of dollars of CTIS parts in my garage. Also, would like to find a local hose place to crimp my own fittings to rebuild old hoses.

I've collected a bunch of stuff over the past few years of New Old Stock CTIS stuff. I may start to sell it soon to fund the purchase.

My local hydraulic shop was able to make me a custom hose with correct metric fittings for my LMTV wheel conversion on a 5 ton.

I was thinking along these same lines. It just needs to fit the valve stem threads, make a right angle, and connect to the CTIS wheel valve. Making one might be easier than finding one.

Thinking about wandering around Afghanistan with an adjustable wrench...

I have purchased a lot of different adapters with all different types of threads, (NPT, ORB, UNF, BSP, JIC, D07, list goes on) and all seem to fall short on finding the right threads for all the fittings. I'm not a hydraulic guy, so that doesn't help. The ones that is really a bugger is the valve stem thread. Especially when it comes the the latest generation fittings on the hoses. It's almost like Dana/Spicer went to Eaton/Parker, gave them specs, & they make these fittings just for the application. There are some fittings that are close, but not it.

Bunch of people had shops try & make hoses & they didn't work out. If you have part numbers for the fittings used, please share.

I had planned to recycle the fittings on bad hoses and use new crimps.

Not a bad Idea. Have you tried metric fittings? I know that I needed a metric adapter to go from the ctis wheel valve to JIC to be able to make a hose on the hub side.
