Bryan,

I'm pretty sure I took the whole driveshaft out of mine without moving the engine or trans. I think if you drive both pins out of the rear couplers, the whole thing can slide forward on the shaft. Then unbolt the rag joint at the front. You may also have to drive the pin out at the front. You should be able to tilt the rear up and pull it out. You should be able to do this on any model with rag joints at both ends. Check the bronze ball bushings while you have it apart. You may even want to have those on hand for when you take it apart.

You should be ok mowing with only 2 blades. Make sure you put the new fan a little further forward. I'd get some extra pins while you are at it. I don't like to re-use them. A lot of times when you drive them out, it puts cracks in them or they are just cracked from use. I consider them a "consumable". I buy them 25 at a time from McMaster Carr. You can get a bag of 25 for about what 3 or 4 cost from CCC.

Todd,
Are you using the "standard" or heavy duty coiled pins from McMaster? I have some of their "heavy duty" pins that I had trouble driving them through the hole in the drive shaft on a 100. They would not compress enough to go in, and trying to drive them in would split or mushroom the end. I tried both a correct size roll pin punch and a flat end punch slightly larger in diameter than the pin, with the same results. I ended up using one of their "standard" pins.
May you always have as many landings as you do takeoff's.........

Paul,
I have only ever used their heavy duty ones. I have used some of the stainless ones too. Never had any trouble putting them in.

I'm thinking of the older models that use a snap ring to hold the fan.
