In the never ending saga to have more modifications on my 70 commando than anyone, I added a transmission filter to my return oil line. It was a simple project who's details were recommended by Jim Comstock as a alternative to adding the late model filter kit parts...
Parts:
NAPA Automatic Transmission Filter - In-Line Part #: ATP 18721

Premolded hose- https://www.retromotioninnovations.com/products/3-8universalmolded
I also made a curved bracket that fastened to the lower central oil tank bolts. I fixed the filter in place with some rubber to cushion the filter and 2 zip ties. The hose is 3/8" internal and I just muscled it onto the oil junction fitting and the oil tank fitting. The molded hose alone has all the bends needed to do the job.
Here's the timing side:
and here's the primary side view. I still need to trim back the rubber sticking out on this side.
The smooth line in front of the filter is my crank case breather lines from my dual breather set up... The clamps are the double tooth Mcmaster-carr clamps. The molded braided hose is rated for 125* C, which should be good enough.
*Obviously my commando is not spotless nor free from any scraped paint, dirt, nor the occasional oily or rusty nut and bolt. This post is to share the modification and archive an easy way to add an oil and magnetic filter to an early model commando with the central oil tank. (thanks as always to Jim)
