Coat the threads with anti-seize compound and fill the hex socket opening with heavy grease or wax to keep it from being damaged by battery acid in the future.
Replace the slotted plug with a hex socket plug. You may have to drill the original plug and remove it with an easy out. Its a slotted plug and because its located under the battery it often is corroded. The fill plug is located on top of the casting under the battery carrier.
If it has manual steering, You can probably drill the casting and tap it for a plug but I believe you should be able to drain the steering box by simply removing one of the bottom bolts from the seal caps on either side of the gear box. Water leaks there also tend to take out the upper bearings. I assumed the shaft was solid, but after pressing the pump doesn't turn anymore, and it. On the first pump I used a hydraulic press and supported the pump impeller. I am replacing the water pump on my 57 MF 35, and I'd like some advice on pressing the pump on the pulley together. The water usually gets in when the seals under the steering wheel go to pot. Posted: Tue 2:21 pm Post subject: MF 35 Water Pump. If that happens the only solution is to replace that recirculating ball nut steering gear/shaft. If you have water in the steering box and its been in there for any length of time there is a good chance the recirculating balls in the worm drive have rusted and pitted. I don’t want to remove it from the tractor. I thought about drilling and installing a plug on the right side where there is a blank spot. There is water in the steering box of my TO-35, but there is no drain plug. OVERSIZE 01-0017 COOLING FAN 01-0018 OIL PUMP 01-0019 WATER PUMP AND THERMOSTAT 01.
