mott 72 flail mower roller rebuild

[jonsstihl]

Any one have any ideas on how to get a tie shaft out of a 6 foot roller. I managed to get the nut off the end but now the tie shaft seems to be a tight fit on the bearings and the roller is kind of big to handle. I have it soaking in 50-50 mix of diesel and atf but

I need to replace one roller bearing.

I got it off.

I used the rollers weight against itself. I threaded the nut on the end of the shaft then held the roller vertically and dropped it onto a thick steel plate I had set on the floor. That drove the other side bearing right out of the roller as well as the tie shaft. Now I need to use the same technique to get the roller bearing from the other side out of the roller since a 7 ft 1/2 inch bar used as a drift isn't working.

Sounds like you're wrestling a bear for a piece of salmon this morning. When my mott had that roller with the inside bearing (been changed) I used a slide hammer puller to get one of them out the other side fell out. That's a good design and last many years but my roller finally broke into and I had no luck welding it back together. Good luck..
