Hello. I hope everyone has survived winter unscathed. FULL DISCLOSURE: This question has nothing to do with an old truck (which is why I'm posting in the Tools forum; and, it involves a tool selection), but the response may help someone trying to do something similar with an old truck.
I'm overhauling a submersible pump (seals, bearings, etc.). When replacing the ball bearings (see picture), the manual says to "heat the bearings until the inner race reaches a temperature of 230°F and the inner diameter expands. Then quickly press bearings on the shaft before bearings start to cool and contract. Temperatures in excess of 230°F can degrade the bearing grease."
I'm wondering what's the best tool for heating the inner race, and how to know when it's near, but not above, 230 degrees F. I know a torch is a common approach. I have a small butane torch for sweating copper pipes.
Could I put the entire bearing assembly in a properly heated oven? Thanks for any ideas.
Yep, oven. The additional step if possible is to freeze the shaft for a few hours or even overnight in the freezer. Then with good gloves on slide it all together.
The hot plate section of an old Mr. Coffee machine works pretty well for heat-expanding parts. I've had one around the shop for several years for such chores. Pistons for Volkswagen air cooled engines used to need to be heated a little so the wrist pins would slip in easily. A toaster oven purchased from a flea market or yard sale would be another way to avoid being the target of the boss lady's wrath for stinking up her oven! Jerry

Good advise HRL on thinking of the Boss. I've been guilty of boiling carburetors on the kitchen stove, baking wrinkle black painted valve covers in the oven and once....before a rainy deer hunt I slathered Sno Seal on a pair of leather boots, put em in the oven on the very lowest setting (150 degs or so) and went to bed. Welllll, next morning the wife gets up to cook breakfast biscuits, I'm in bed and hear all kinds of bad words coming from the kitchen. Yep, she had turned the oven on to preheat it prior to putting the biscuits in......without looking. WHAT was she thinking. Needless to say SnoSeal was the least of my problems.

Reminds me of the time a roommate and I cleaned the carbon off a pair of heads on the kitchen counter of our apartment. Fortunately neither of us had a wife at the time.

Sounds like some of y'all didn't properly break in your ole ladies early enough in your relationships to do you any good. I'm afraid its too late now... Kinda like breaking in a new cam. You only get one shot at it. Early on in my marriage I used her seldom used food processor to grind up castor glands from beavers to create beaver lure. She's still with me, and she isn't a big ole gal, nor is she ugly. Apparently I am quite the catch. (Just don't ever ask her.)

I’ve been training mine for 44 years and she still flips out if I use her vacuum to clean up after scraping intake gaskets. Did you know if you forget about the chestnuts you’re roasting in her oven they explode. Got to get me a toaster oven great idea ðŸ‘

These old bolts are in my blood. Hard thing is focusing on just one.

Okay. Back on topic. Before this has any type of a chance in heading in the wrong direction.
Why? Because we always seem to do that as a general course of business. We never quit while we're ahead.
My shop has a dual burner electric hot plate. I'll place a piece of sheet metal over the electric burner to spread the heat more evenly. When it comes to flywheel gear rings, sometimes you have no choice but to use a torch.
