I have to be missing something here I hope. Fan belt broke on 3010. Had to remove the hydraulic pump coupler assembly ( the coupler and the two giant discs) in order to put the new fan belt on. How on gods green earth do you reinstall the coupler assembly? I am finding it almost impossible to get the bolts lined up and threaded back in since you cannot see the bolt holes. What is the trick? I think I am learning why the coupler assembly on a 3020 is different!

Ditto. Newer style coupler is much better. It's difficult to believe the old coupler plates aren't cracked after all after 50+ yrs of service

I am with the others. Change it to the 3020 style. Much quieter and easier to work on. Like Tx Jim says the few originals left are usually cracked by now. Tom
Thanks guys, that's $50 I had not planned on spending but I guess if you value your time at all it can be justified. All State Ag PArts shows two types of drive pins. Do you buy 2 of each (a pair for the engine side and a pair for the pump driveshaft side)?
BTW the metal discs look perfect after 57 years, wonder what that means... (I guess only a crazy man would have replaced them if they were damaged therefore I think its pretty safe to say they are original equipment). The shade tree half-butt mechanic in me wonders why the discs are there. If I "lost" one or both of them the reinstallation would be a snap, as currently its a very snug fit between the engine and the pump driveshaft, which is pretty much the cause of the reinstallation difficulty.
