Looking for a spark plug replacement for the AC #K-11. Also have a leak in the front of the transmison. I understand that the standard does not have a slinger as most other do. Any help out there?

Try AC C47, 48 or C49. Champion UJ-12 Autolite AZ9, AT10, A11, or equivalent.

1934 Masters and all 1935 and up use an AC 45 spark plug.I run AC R45 resistors in my '34 with no problem.
It will be necessary to remove the transmission to check for cause of leak.The front bearing retainer has groves in it to help thread the grease back into the trans, case.It could be loose, broken or worn.Also too heavy of grease will cause it to leak when cold.Use 85w-140 for best results all yaer around.

Thanks Chev Nut. I have rebuilt the Tranny, new front bearing and etc. The owners manual in one section calls for 1 1/2 pts of oil and in one section says to fill to the bottom of the treads in the filler plug. I have used 90W160 and 500W both leak, realy leak!!!. The only thing I haven't done is put 1 1/2 pints in it. I filled it to the bottom of the treads. Any other idea be for I pull it for the 3rd time?

If you do pull it for the 3rd time, use a front bearing that is sealed on one side, the front side. I have done this with good results, however make sure you don't do the same with the rear as it needs to leak thru to oil the uni joint

The capacity ( 1 1/2 pints) will fill it to the bottom the the filler plug hole.I wouldn't overfill it but you could try running it about an inch below the hole (when cold).I would doubt if a sealed bearing would help.The gear oil is designed to return thru and around the bearing.

On the spark plugs-- AC Delco says to use R43 for K-ll"s. Any 44-48 is hotter and only needed for a oil burner.

1941 parts book list #43 for"use on jobs receving unusually severe operation"----1952 parts book lists #45 and #46 for average operations.#43 is a very cold plug-it will foul unless the car is used for high speed driving only.I have found that the #45 is a good all around choice.The #43 never came in a car from the factory--the 45 was used after the K series was discontinued.
The #47 and #48s are very hot.We used to use them in cars that were oil fouling the plugs.
