Oil cooler fitting on a MEP 016B diesel genset

[Jim_in_Omaha]

Hello all..
Working on the engine from my salvaged genset. The oil cooler has some fittings that I do not know anything about. They are like a cone type fitting with no threads or mechanical locking to them. There may have been some kind of sealent glueing them together? Anyway they just pulled apart on this thing. The female fitting on the outside is hex shaped for wrenching, on the other end it does have threads for like a 1/2 NTP connection.

How do I reconnect them?
thanks
Jim

Aren't those sweated on? I'll have to look at the one i have. Do you have any manuals for it?

They are aluminum or some kind of alloy. Both of them just pulled off without much effort. I have all the manuals. I'll look threw them again.
thx

I've been looking for those manuals. Could you tell me where you found them?

I would have to email them to you. PM me with your email address.

Can we revisit this, Are they sweated or is their some other trick? Thanks in advance.

The parts manual calls that a "bushing, nonmetallic". It is probably a spacer of some sort or guide for the hoses to go through a plenum or something.
Probably protects the hose and/or fitting from rubbing on something. IIRC, the oil cooler is inside the scroll so maybe the lines pass through the scroll and the bushings protect them. I don't think they sweat on, more likely press fit or friction fit.

The maintenance manual calls them "sleeves". See pic.

I looked at the 016B I have in my garage currently and also compared it to some pics I had of 2 others that I sold recently. They are not the same.

However, I believe this is a sleeve that assembles to be trapped between the fititngs when the hose is assembled to the cooler. The clamps that hold the cooler and hose to the housing fit over the sleeve. The one I have in my shop right now is set up this way but it also has an extra adapter fitting not shown on the parts picture. I think the function of the sleeves is to fit between the clamps and the fittings.

I'll post some pics when I get back in town on Wed. if not figured out by then.

Derf & ETN I really appreciate it. It sounds like mine is the latter described. It just seems very easily disconnected for an oil line. I would like to know if you guys trust them or should I get some aftermarket hoses & cooler?

The stock stuff is well engineered. You don't really need to upgrade the oil cooler, I think.
