For the install, get a coffee can, 30wt oil and put about 2 inches of oil in the can, get it smoking hot, drop bearing in the oil, get it hot remove bearing from can and install the bearing. The bearing has got to be smoking hot or it wont go all the way on. Use gloves when doing the install.
Is heating it what the book says to do? I can't say I've seen that in any book. I would suspect a press would be used. Maybe a bit of the correct diameter pipe and a bolt in the end of the crank? I can imagine that immersing a bearing in a can of boiling oil, can be good for the heat treat in it or the temper of the metal.

In the JD service manual I have it says to use the proper dealer tools & a press, which most individuals or small repair shops don't have, so the heating of oil " NOT boiling of oil" in a pan then putting the bearing into the hot oil method to expand the bearing has been used for many years, with success & never any problems..

I found this on the net..

Bearing Installation

Learning Objective
You will be able to install shaft bearings according to procedures outlined in NAVSEA 0900-LP-060-2010 Series.
Background
Most bearing failures are caused by contamination of the bearings before they are installed. In turn, bearing failure causes other mechanical and electrical failures of motors.

Proper bearing installation ensures long bearing service. Proper installation depends upon uncontaminated and properly fitted bearings. This ensures long motor life and avoids later unnecessary repair work.
Bearing installation
Ensure that the workspace, equipment, and tools are clean and ready for immediate use.
Rinse open-type bearings or bearings used in oil-lubricated systems in clean 2190 TEP oil to remove grease. Heat the oil to 140?F ? 10?F. Agitate the bearing in the oil until all grease is removed. Drain off excess oil. If it is a grease-lubricated bearing cleaned for use with oil, prepare the bearing for heating by putting it in heat-resistant plastic or aluminum foil.
Caution.gif (1040 bytes)
? Never spin a bearing with an air hose during cleaning or drying.
? Never immerse grease-lubricated bearings in oil or solvent for cleaning.
? Do NOT use compressed air as a method of cleaning, as air hoses may have moisture or dirt which could damage the bearing.
? Do NOT use brushes as a method of cleaning, as brushes may leave foreign particles inside the bearing.
Heat the bearing
Preheat a heat-controlled oven to 203?F ?10?F. Heat the bearing in the oven for 30 minutes to 1 hour. Ensure that the bearing is fully expanded.
Install the inner bearing cap on the shaft. Reinspect all parts to ensure that they are free of dirt, burrs, and scratches.
Using clean, thermo-insulated gloves, remove the bearing from the oven. Remove the plastic cover or unwrap the aluminum foil from the bearing.
This Posting wasn't for snowmobile bearings but to show that the heated oil method is used & recommended..
Personally I have never heated one in an oven & never for 30 min. to an hour, just never needed to heat one that long, I would say 10 to 15 min max should do the trick.

I stand corrected. I knew it can be done that way, just never saw it done, or even heard of it being done.
