In our quest to stop oil leaks on our 196 OHV, we decided to replace the oil pan gasket.
Jack the front of the care up, and put it on jack stands. Put 4X6s under the front wheels as well, just in case. You can't be too careful. The radiator needs to be drained and removed first. Be careful not to dent the fins on the radiator. It is a tight fit pulling it out.
Remove the fan:
We have a 440H with power steering. There is a bolt that needs to be removed to relieve tension on the belts. Notice the spacer:
Here you can see the power steering pump with the bolt and spacer removed:
The front pulley needs to be removed. Note that you don't need to remove the center bolt. We did anyway, but there was no reason, because the pulley has a large center hole that just fits over the vibration damper:
The reason why you have to remove all of this stuff, is that the screws for the front of the oil pan are blocked by the pulley. The generator also needs to be loosened so that you can remove the belts. Watch out for the slider bar on the generator. At least on ours, it is connected to the inner bolt by a notch, and not an entire hole. This means you could probably loosen the entire generator by loosening the bolt on the slider bar, and then just rotating the bar so the notch held by the inner bolt is dislodged. Here everything is out of the way:
Here is the pile of parts we had to remove. You can see our moveable chicken coop in the upper left corner of the picture. Notice the crossmember, which is the only obvious part here. We really thought we should be able to remove the oil pan by simply removing the crossmember and being tricky with wrenches and sockets to work around the pulley:
We removed the two lower bolts from the steering box, and loosened the top one. We then pulled the pitman arm off using a puller:
The nut holding the pitman arm to the steering linkage could have stayed on, but it was something we tried along the way, but gave up, luckily. Here you can see the oil pan removed:
