You said you wanted to split it at the front of the transmission instead of the front of the bell housing. Why?

I have never split an AV, just A's and other conventional tractors but I'll give my thoughts.

1. The first thing is to have a good hard level surface.

2. Block between the front axle and the engine securely. You need to cut wedges and wire or bolt them to the axle to prevent the engine from laying over when you split the tractor.

3. Remove as much as you can (and will later need to anyway) like the hood, head, pan, pistons, radiator, etc to get the weight down. This is not the way to go, obviously if you are only changing the clutch.

4. Remove the steering shaft.

5. Block up under the front and back of where you are going to split it and use wedges to snug up the blocks. I find it best to roll the transmission away from the engine because it is more stable and the bell housing will slide on a 4X4 nicely.

6. If you are going to remove the block from the axle to have it vatted, etc. you really should get a chain fall (chain hoist to some) or as a poor second best, a come-along, to support the engine as you remove the front axle. Take the time to chain to three points on the engine and make each chain adjustable (bolts or all-thread through links work) so you can adjust each chain to hold the engine level. This saves a LOT of headaches, smashed fingers, damaged gaskets, etc. With a chain fall, you don't need to block the engine, and with a conventional A, you can roll the bell housing and rear end back on a floor jack. An AV may be too high to just support on a jack. Very little should be placed on top of the jack to make it taller, unless any extension is bolted down you are asking for trouble. Putting the jack on cribbing with a plywood platform on top to roll the jack on is a good alternative.

7. After everything is supported well, take the bolts out and roll the transmission back. If the engine is hung from a chain fall be careful the front does not move with the back, raising the rear of the engine and getting the input shaft in a bind in the clutch. Alternately working the back wheels by hand will usually free the joint between teh engine and bell housing.

8. Was that all clear?
