How do you remove the PTO shaft from the flywheel? I suspect taking apart the U joint would be the easiest, but don't know how they come apart. The shaft got bent slightly so it will not telescope. Thanks in advance! ------------- '49 G, '54 WD45, '55 CA, '56 WD45D, '57 WD45, '58 D14, '59 D14, '60 D14, '61 D15D, '66 D15II, '66 D21II, '67 D17IV, '67 D17IVD, '67 190XTD, '73 620, '76 185, '77 175, '84 8030, '85 6080 |

Taking apart the u-joint may not help. You still have the remaining 1/2 of the joint attached to the flywheel. I’m not familiar with the 303, but removing any shields/guards, looks for a ‘set bolt’ or maybe even a bold that goes all the way thru the u-joint and shaft, more than like likely a key shaft or two the u-joint slides on to. ------------- I tried to follow the science, but it was not there. I then followed the money, and that’s where I found the science. |

| There is a nut holds the yoke that is the over running clutch onto the slip clutch. The slip clutch is half to the flywheel with three 3/8 bolts |

It doesn't look like the nut can be removed with the U joint in place (unless a box end wrench will fit in there???). Socket or open end wrench doesn't look like it will fit. I did look at the 3 bolts holding the slip clutch to the flywheel - they will not come out all the way unless I take apart the slip clutch. ------------- '49 G, '54 WD45, '55 CA, '56 WD45D, '57 WD45, '58 D14, '59 D14, '60 D14, '61 D15D, '66 D15II, '66 D21II, '67 D17IV, '67 D17IVD, '67 190XTD, '73 620, '76 185, '77 175, '84 8030, '85 6080 |

| Are both pieces bent or just the piece that slides inside? |

| It will take a regular box end. Ratcheting version won’t fit. It will go round and round one way. Not the other. Don’t remember if removing or assembly was the easier way but it’s not bad at all |

| I modified a box wrench to fit...If too tight a crack with hammer and chisel. Loosen the nut before any thing else... |

Don't know. The shields aren't bent. Once the shaft comes off, I will have to figure out how the shield comes off to see whether it is one section bent, or both. ------------- '49 G, '54 WD45, '55 CA, '56 WD45D, '57 WD45, '58 D14, '59 D14, '60 D14, '61 D15D, '66 D15II, '66 D21II, '67 D17IV, '67 D17IVD, '67 190XTD, '73 620, '76 185, '77 175, '84 8030, '85 6080 |

Update: 15/16" Box end wrench was able to fit the nut on the flywheel
and the shaft came off easily. Next issue is removing the shields from
each end of the shaft. Parts book shows a snap ring by the U joint, but
I have not seen it up close in person. Anyone have any hints?   ------------- '49 G, '54 WD45, '55 CA, '56 WD45D, '57 WD45, '58 D14, '59 D14, '60 D14, '61 D15D, '66 D15II, '66 D21II, '67 D17IV, '67 D17IVD, '67 190XTD, '73 620, '76 185, '77 175, '84 8030, '85 6080 |

| On the shaft on the hood. There is a small slot near the support bag. That is the snap ring slot. Push it in on all the slots and slide shield off. On the other side line up hole with the roll pin and drive out. The yoke will slide off the shaft and shield will slide off |

Next issue: for reinstalling the shields over the shafts, how do you lock the snap ring into the 3 slots? ------------- '49 G, '54 WD45, '55 CA, '56 WD45D, '57 WD45, '58 D14, '59 D14, '60 D14, '61 D15D, '66 D15II, '66 D21II, '67 D17IV, '67 D17IVD, '67 190XTD, '73 620, '76 185, '77 175, '84 8030, '85 6080 |

| Use a screwdriver to walk ring back into the guard. Then turn until detents pop into the slots. If you can line bumps up with slots it will snap in easier |
