    07 250X Pump at 147 hours

    I pulled my pump with 147 hours worry about the possible damage to the engine in case of failure. To my surprise both the bearings and the shaft look brand new. Here is a picture of the shaft and it has no heat mark or anything.
    I do have 3 questions:
    1. How do I get the rear bearing off if I don't have a press
    2. Do I need any special tools to get the front bearing off.
    3. When install the nut in the back of the shaft, does it have to touch the bearing or close to the bearing?

    Also I am going to get the 2010 shaft and perform the Connass mod. I got a quote for $45.99, part #13107-3809.

    you can remove the bearing from the shaft by supporting the bearing ontop of a vise with the jaws resting up against the shaft not touching though, basically so the centre ring on the bearing is being supported then with a soft hammer or block of wood knock the shaft off. depends how tight its on to how it will come off. this way not recommended as it could bruise the end of the shaft a press would be better. i would refit a new one in a press though.
    use a press to remove the bearing from the housing, it is pushed out from the front to the rear, after you remove the seals insert a socket extension or similar to the centre of the bearing supporting the housing from the bearing carrier on the inside and push it out. re insert a new bearing or bearings using a press and press them in from the outside bearing ring. not the inside.
    have the nut lock up to the bearing centre

    Thanks for the quick response. I don't have a press, so I will take it to someone to press it out.
