Oil lines, dumping oil out of the cooler

My XJ750 has a nice leak out of the cooler, it is not the OEM cooler. I would like to replace the lines and get one of them fancy screw-on filter adapters from Chacal. I haven't seen any post on the here about making new lines, I was under the impression that it would be an easy off the shelf line replacement? Anyone now the ID/OD on the lines if so?

 

I don't know the line specs, but I know the kit that Chacal has comes with an adapter for the oil filter, mounting hardware, radiator, and lines. He likely sells just the lines as well.

 

Take your existing lines to any shop that deals in hydraulic equipment, or farm implements. They can make replacements.

 

Some pics of the cooler and lines will help identify it as it is not stock on the 750.
Could be 650 seca turbo, or 900 seca.

 

I bought the adapter from chacal, I am sure that with the lines that come with that and the existing ones I'll be able to rig something up for it. Looked more closely last night and it is a Lockhart oil cooler. Hoping that it is just a barbed fitting on the cooler side and I can just clamp that side. What pressures are typically seen in these lines?

 

OK Lockhart just uses common low-pressure oil lines. It's the same that you'd find at any auto parts store. The fittings at both ends should be slip-over with a bead at the end, hose held by a clamp.
Engine operating oil pressure isn't given, but is no higher than you'd see in a car. The oil pressure relief valve opens at 71 PSI, which normally would never need to be opened.

 

Ummm, you bought the spin-on oil filter conversion kit, and it does not come with ANY lines! It merely replaces the finned oil cover/paper filter system..........

 

Crap.... I'll have to make the ones I have work then! OR make new ones using off the shelf parts.

 

You already have the adapter needed for the oil cooler since you already have an oil cooler installed. As mentioned before all you need is to get new lines cut or made.

 

Lets take a step back for a moment.

Make absolutely sure it is the hose and not the cooler that is leaking.
Oil coolers experience a lot of stress from vibration. The rubber hose hardens over time leading to more shock and vibration transferred into the cooler. All this can add up to fatigue and stress fractures in the seams and metal lines in the cooler. Oil coolers need to be rubber mounted to help isolate them from vibration.

If you have the typical swaged clamp on the end of the hose. Carefully cut the clamp to remove it.
The hose will be pushed over a flare in the line. Cut a slit in the end of the hose to release the pressure and slide hose off.

Now I will go get some popcorn ready for the debate!

 

I haven't seen one in person for a long time, but as I recall the Lockhart cooler is rubber mounted. It uses worm clamps at both ends of the lines, not swaged clamps.

+1 on making sure the cooler isn't leaking though.

 

Just covering the bases. I'm sure you have seen some interesting things done as well!

I replaced the factory oil filter with a spin on, tightened the hose clamps on both sides of the lines and cleaned the whole area up. Now if/when it leaks I should be able to more easily spot where the leak is from.

 

A light dusting with baby powder will show a oil leak quite easily.
