Take them out, pull the pump scrap the old cork gasket off. Replace the gasket and reinstall the pump. Remove the brakes, 2 bolts on each side. Remove the rear cover 9 bolts. Pop the C-clips in the center of the diff and pull the axels out. Remove the C-clip that retain the seals if you have the external C-clips (some are on the out side some are behind the seals) remove the seals. Remove the axle tube bolts 4 bolts on each side remaining because you have already removed the 4 that held it in the frame. Pop the tubes off and clean up the mess that will be inside them. Drill a 3/8" hole in the bottom of the case for an oil drain on each side of the case. Clean and reassemble in reverse order. Here is the parts list you will need and cost.

Well, I have taken two cuts with the 18HP on the 1641, and I decided I miss the power steering.
The 18HP adds some weight to the front end and it's noticeably harder to steer at times than previously, especially when one handed.
(Thinking about nibbling out a circle in the fender opposite the gas fill and installing a cup holder off a craftsman fender I have sitting out back)
So, this parts list is on order, and I'm going to try to salvage the rear and put it back together with a helicoil in that broken bolt hole. I've stared at it now for several days and I believe there might just be enough aluminum material left to get a helicoil in there and have it hold up. I attached a picture of the damaged hole:

This has me wondering, since I will probably have to buy a pack of helicoils, would it benefit me to drill all the holes out and install them in all the holes while it's apart?? If my repair works, I will put it back in the 1864, and move everything back... and all the stars will align, and dogs will be sleeping with cats, etc... I already have the axle tube drains drilled into the case so that's all set.
