1940 Chev C15, Cab 11 restoration in Holland

[Bob Carriere]

These pictures show the actual location on a HUP frame which by coincidence is the same as for a cab 11/12.

From my limited experience..... every cab 11 and cab 12 that I have acquired and worked on NEVER had an oil filter installed....even retro fitted. Remember these are trucks that probably never left Canada and were never retrofitted with oil filters in field workshops.... probably giving priority for front line use. Similarly most cab 11 in Canada do not even have the bolt holes drilled in the frame for the fuel filter....which is located on the opposite side under the driver's seat.

Any ways the HUP pictures clearly shows the ackward location inside the frame on the passenger side...... mechanics must have loved doing filter changes and getting an oil bath everytime....

Glad to see that my thousands of pictures are finally useful....

On the original installation... the oil lines have a reverse flare and are called ... not sure if I am correct.... a Weatherhead connection..... and they are next to impossible to find today...... which means that you have to fabricate your own junction brass block as the original will ONLY accept the reverse flare tip on the hose.

If any one can share more information on these weird old style design please chip in...

Bob the original brass junction block may have been drilled out rather then milled out hence the tapered ends on the hose fittings. Is it not possible to put the modern square ended hose fitting into a lathe and turn a taper on the end the same as the original as they look the same length?

The picture attached is of my 1941 C60L Pattern 12 as I found the truck. The filter location is shown and is the same as on my 1942 C60s Pattern 13. This has got to be one of the nastiest places to try and drain, remove the filter, clean out the filter housing oil all drains down on the exhaust pipe nice to work on if you just shut the engine down to drain the oil while it is hot.

The inside of the brass block looks carefully machined to accept the matching tapper of the oil line....... the modern fitting will screw on but will leak a lot under pressure due to the absence of a mating surface. The easiest would be to either make a new block externally identical but set up to take modern fittings or machine a brass adapter to fit the tapper and accept the new thread style at the other end.

Occasionnaly the old style oil line appears on Ebay BUT are usualy too short to be of any use.

Phil ...... hot engine oil down your sleeve is a sure way to wake you up in the morning....... none of these vehicles..... especially the cab11/12 were ever design for the comfort of anyone.... mechanics or the drivers....

...and being sadistic and masochistic that's why we love them...

A few wraps of teflon tape on the threads would likely solve the problem.

Thanks guy's for all the helpfull info, before I show some more pictures I wondering how did they fill up that oil filter after replaceing the filter element?
oke back to my own project I placed the gearbox in it's place and installed the small compressor on the left side. I also started on the fueltank brackeds witch needs new straps to hold the tank. I strated on the tank to and under all the dirt and old paint I found the original number Z4200302 I did not see a C so ... I want to make it british anyway (because of the british radiobody).
see the next reply to for more...
cheers jaap
