You need to tell us if it is a front or side mount distribuitor engine.. Hint.. front mount engine has a cap with 4 wires and uses a square coil that sets on the top of the distrib.. takes 15 minutes to remove the 2 bolts holding the distrib tot he block, remove it, change points and cap and condensor and rotor, and replace.. and that includes the beverage of choice. Side mount or angle mount distrib is the conventional 5 wire and uses a round coil on the side of the engine.
TSC sells a tune up kit for either that has a cap, condensor, rotor, and points, and single use feeler gauge for the points, as well as 4 spark plugs.
OEM plug/range was a champion H10.. most N owners prefer a range hotter and use H12.. or more preferable, an autolite 437
Spark plugs gap at .025
Points on the front mount gap at .015
points on the side mount gap at .025
Tranny shares the sump with the hyds and diffy.
takes about 5g. Remove the lowest bolt in the round cover with the dipstick.. add trans oil till it dribbles from there.
Original oil spec was 90wt mineral oil.
Napa carries 90wt gl-1 oil in a 5g pail as part number 65-205
You can use pretty much any 90wt gl1-gl3 oil.. Tractor supply sells an oil marked for fords 1939-1952.. that will work fine.
CNH reccomends a UTF oil meeting M2C134D... ( just about any UTF.. even walmart UTF, meets that spec ).
An 80w90 gear oil in the gl4/gl5 range that is specifically marked to be yellow metal safe.. or safe for bronze / copepr alloys would be ok.
If you live in arctic weather.. the 90 wt oils will be sluggish till they warm up... In real hot areas, if you have a leaky lift.. the uTF oils will perform worse... take your pic.
