thank you both. I have a good assortment of tools and a press, yet could not figure how to chuck up the shaft in the press because the wheel flange is too close to the bearing and there is insufficent space between the beams of the bridge/table on it. Pressing the bearing on will be no problem. After removing the snap ring the bearing did not budge and prior to messing with it more decided to ask here and order the seal and new bearing. Bearing is still on the shaft and I will be 'messing with it', or may order the splitter (that I no longer have access to because I recently moved hours away from my friends shop that is better tooled than mine.
I thought about using a mapp torch (plumbers yellow cyl torch) to gently heat to see if that would release the tolerance fit.
Due to time and availability I ordered on-line at the first place that I found. Anyone have suggestions for a good online parts source for future reference?
After I finish this current job of installing a new case, I'll be ready to work on my antique chronograph. New case is due to original owner replacing a shear pin in the pto shaft with a grade 8. Both bearings on the output shaft came apart, and busted the bearing seats in the case and cover along with a tooth from the output shaft. These little tractors make power that can mess things up good.
