F-12 oil change

This is a confusing one. I have the book, and I have the 1935 lube chart, and it is printed wrong, as the numbers on the arrows pointing to lube points is not the same as the numbers on the corresponding chart. Anyway, the drain plug is on the bottom of the trans. The fill plug seems to be on top, right in line with the rear axels. The oil level plug is under the front of the trans. Fill until it runs out of the oil level plug. If this dont make sense, and nobody smarter answers by tomorrow, I will go to the shed and look at my F12. The specs for the oil are 2 paragraphs long, as they did not have the same numbers that we now use. I suspect 90 weight gear oil will be fine. The engine fill is a big cap at the left front of the engine, with wings on it like a thumb screw. Fill with oil until it runs out the top test cock on the side of the oil pan. Make sure the test cock is not stuck with dirt, or you will put in 5 gallons by mistake. A wire poked in the hole will help. A new oil filter is a good idea.

The tranny oil goes into the hole under and just in front of the driver's seat. I used 120w-90. Five gallons at Pep Boys was about $25. Manual says to put in four.

By the way, when you drain it, expect anywhere from 5 to 15 gallons to come out. Water gets in over the years and adds to the oil. It will probably come out coffee colored as a result. 15 gallons is a lot of oil to dispose of. Can surprise you.

Engine oil goes into a fitting between the magneto and the radiator. Unless you have cleaned out the engine, use non-detergent oil (so it doesn't loosen the crud and clog everything). I got that at Pep Boys too. Cheapest oil they had. Fill oil until it runs out the top petcock mounted on the oil pan. Or, just put in 5 1/2 quarts. Manual calls for 30w. Rice has oil filters. It goes into that dome shaped fitting on the other side of the magneto.

Rice is a good source of parts. Call him.
