Obviously the bottom half is easy, but is it do-able/possible to fit the top half of the bearing up there? I know both halves must match and I know its "best" to pull the crank but rods and main journals look and feel great (and rods measured up good and std size) and this tractor (Super 55) won't see more than 30 hours a year and I am on a budget.

In one of my service manuals, they specify making a "tool" by taking a cotter pin and smooshing the eye so the pin looks like a "t". Then, you can insert it into the oil hole in the crank, turn the crank, and it will roll the bearing out. [Reply]  [No Email]

When I was typing out my reply, I was wondering if someone was going to make note that the triple digits did not have drilled cranks for pressure fed rods. My intent for mentioning what I did was to demonstrate how common it is to roll in new bearings without pulling the crank. [Reply]  [No Email]

Loosen up the main cap or sometimes you must loosen up two but remove one at a time. Rotate the bearing out notch side first, then reverse the procedure to slide in the new one. The thrust bearing can be a bear sometimes. Re-torque and a job well done. [Reply]  [No Email]

Do not try to push the notch around the crank go the other way with the notch comeing out first. [Reply]  [No Email]
