Transmission cooling line refresh
 

Does anyone know of a hydraulic shop in the Kansas City area, or someplace within a few hours in any direction, that can crimp the ferrules for our lines? I've been turned down by three places so far. :banghead:

Thanks,

Buy a crimp set up from http://www.ackits.com/ and do it your self. Very shortly the crimp set will pay for itself.

As an alternative you can use high pressure FI gasoline clamps. They have to be fitted perfectly for size and must be full metal. But they will work as well as crimps.

I had mine rebuilt by the local Pirtek franchise. They were the only shop near me that would do it.

Looks like there's one in St. Louis, if thats not too far.

Check and see if there is a Tubes-n-Hoses franchise in the area. They can do most any type hose regardless of manufacturer.

I used FI clamps (Same type that people are using for the fuel line kits -Solid not the worm clamps) and double clamped (2 clamps on each end). A little axle grease for lube (and a lot of elbow grease) to get the hoses completely on the barb. You can use a dremel to slice the old crimp from the line (be careful not to scratch the barb). :

I purchased the high temp hydraulic lines from the hose shop that would not do my lines. Their explanation was that the 928 lines have a 'short' crimp, and that the metric lines do not fit their equipment properly. <smh>

Make sure you get high burst strength (1600 PSI) high temp insulated hydraulic hose. The OD of the metal portion of the lines are 10mm. Make sure you use insulating wrap on them once you install them (I used spark plug heat insulation sleeves) and remember to install them properly (they are attached to the car not the torque tube..).

I purchased 6 feet of hose and had about 8 inches left over.

Thanks for the information everyone. I very well may use FI clamps if I can’t get these crimped fairly soon.

After a few tries, I was able to contact the guy from tubes-n-hoses. He said he might be able to do it but wanted me to measure the diameter of the line. I left a message saying it was 10mm, but I haven’t been able to get in touch with him since. I’ll call a few more time next week.

Dan, were you talking about the 71550 - Hydra-Krimp (Basic Crimper) from the ackits.com? If so, have you, or anyone you know used it? It might just do the trick.

I use the vice mounted one. I have done A/C lines and the high pressure FI lines for the early CIS cars. I have have not done the cooling hoses on the automatic although the short line going to the internal cooler had an FI Clamp when I got the car. It did not leak. 1600 lbs sounds a bit excessive for the cooling hoses.

The line was 800 continuous and 1600 peak/burst.

It was silicone jacketed and heat resistant. It was 6 bucks a foot but I figured overkill is better than not enough.

So far its working well no leaks all transmission levels staying solid.

nothing wrong with a little over engineering. But then you are only fixing one car not building a million. Although the quality on porsche hoses even compared to a mercedes is very disappointing.
