#49. Gearbox & OD oil change

Because my filter has a less flexible inner basket weave that would not re-form well,

i did as Randall suggested and used one mag. ring at the base of the OD plug and a magnetic plug in the gearbox.
however next year ( or next time I drain) I'm switching to the mag. Hex socket type of plug.
That big plug post sticking straight down from the gearbox is just asking to be knocked off.

I went with John's suggestion of an O-ring for the OD plug. (Used the 2- 3/16" narrower ring, pictured above & only snug tight , like a spin on oil filter.)

i used redline MT 90 gear oil & a liqui-moly concentrated gearlube additive "MoS2 anti-friction for gears"

(Liqui moly is a German manufacturer that gets a lot of positive press from old German car enthusiast. They make a variety of top rated additives and oils)
So far so good.
the OD plug wrench pictured above (or equivalent ) is a must have if you have the notched plug. Made removing the plug very easy.
i got it from Moss for a rather hefty price of $60. Bucks.

just took it out for a test drive & see no leaks yet, and the car is running smooth and strong.
