Grandpa's Old Tractor FAQs


Q - What type transmission grease do I put in my 8N, 9N, 2N tractor?
A - 90 weight transmission grease. It takes 5 gallons to change the transmission, lift system and rear end. There are 3 drain plugs, one located under each compartment. The grease flows freely from one compartment to the other. They all are checked by the one dip stick. The grease for all 3 compartments are filled by the plug on the transmission cover. DO NOT use universal hydraulic fluid of lighter weight because it may cause seal failure and may weaken the power of your hydraulic lift.

A - You turn the key silly...

Q - I drove out my old connecting rod brass bushings and drove in my new ones. Now my piston pins won't fit in the end of the rods. Are they the wrong size? What do I need to do now?
