John Deere X300 PTO Bearing Replacement and installation

[Jccds]

I replaced the bearings in my X300 but having an issue getting the PTO back onto the shaft. I have verified that the right bearing was used but it is so tight I can‘t get the PTO on the shaft. Any suggestions?

Measure using a caliper inside diameter of bearings & outside diameter of crankshaft.

Thanks Mark, do you know what is an acceptable tolerance for the fit.

A tight push fit is o to ,ooo5" of clearance

As bertsmobile1 posted you should be able to install by using hands, a snug fit. Make sure crankshaft is rust free & super clean. You may need to use a fine grit emery cloth to dress up crank. Antiseize compound on crankshaft will also help & keep from seizing. Remember to install key & torque mount bolt to specs.

I've purchased bearings from a auto supply but returned for the same reason. They took them down to a bearing supply to replace those with the correct measurement. 60 mile round trips aren't much fun to return 2 bearings. More invested in gasoline and time than the bearings cost. If ordered on line it can be more frustration.

Those that are press fit on the OD I adjust with the bench grinder to push fit to avoid un-necessary side thrust which can ruin a ball bearing in short order.

There are two different 6205-2RS bearings ID spec wise. And .0157" does make a world of difference. Most likely the OP install the more common one because they both use the same rubber coated seals.

I driving down the road drunk so get out my way but I just got to have another bottle of Jack before lunch.
