Bearing install

When installing a bearing on a shaft that is press fit, do you guys use a punch on the inside race to fit it? I used a rubber mallet as a block and hit it with a hammer. I figured the rubber mallet would spread the force over a wider area and lessen the shock. Now the bearing has a slight click that I didn't notice before. Never had this issue before but this bearing was one of the tightest I can remember. Thanks!
 
If driving or pressing a bearing on, always use the force against the race that has the restricting surface . Going on a shaft, inside race, going into a hole, outer race. It is acceptable to use a punch carefully if it cannot be pressed on. The click may just be some crud you got into bearing so clean it really good and take a look. We all have damaged bearings and seals over the years.
 
Better still is to use a tube or piece of pipe that just slides over the shaft so you can drive the entire bearing race at once.

Odds are with the wood block and mallet you were also striking the outer race of the bearing. It's tough to hit something in a precise way with something that mashes. That could've caused your click.
 
if you really want to install the bearing properly you will leave your punch and hammer in the tool box and get an old pan with some hytran in it and heat it to 275 degrees and put the bearing in the hot oil for a few minutes and useing a set of tongs grab the bearing and it will fall on the shaft. in a minute it will cool and be tight on the shaft. i use a fry daddy and a candy thermometer.
 
Hot oil is probably proper but I just put them on the propane grill with indirect heat for a few minutes. Slips right on.
