The way you used the cone of the screw to separate the rolling elements, locking them securely in place is actually very clever.

I am an old man and I was taught the grease trick back in the 70's. BUT!! That slide hammer is absolutely BRILLIANT!!!
⭐⭐⭐⭐⭐ five stars for you Sir!!

I once repaired construction equipment in a shop owned by the same family for three generations. Ancient homemade tools were all over the place, including a few pullers similar to this and other ingenious designs. There were a few things that had been worn out for generations looking cool on the wall, too.

👍Doing a service call out in the field you only have access to what's on your truck, so while these are brilliant, there are times you have to make do with what you got. Ive got 40+ yrs out in the field and have used ingenuity such as yours with what i had. Loved the vid and i compliment you. Now i cant wait to go to work tomorrow and get it on!

This is the best kind of video because we dont have some boring talking head that only uses this as a format for an excuse to talk, talk, make lame jokes, bore us to death, etc. Instead we have visual proof of what really works that is engaging.

The ball bearing puller design was a great idea, I'll keep that one filed away. In this case, it would have taken way too much time! Anytime I have a blind race, I lay a couple of weld beads around the ID of the race which shrinks it slightly allowing it to be pulled out by hand (be careful not to 'cock' it in the bore!). It works on any style of race: deep groove ball, tapered, angular contact, etc. I cover the bore in anti-spatter compound to protect it and any other critical surfaces from weld splatter. I've been a CNC machine tech. for close to 20 years and changed out more bearings than I can count. I've had maybe 60% success rate with grease, it either leaks thru the balls or just blows out the center race and balls.

I used the grease technique, until I saw a mechanic friend use wet paper towels and it worked better because there wasn't as much mess to clean up.

Your slide hammer is very impressive. Very ingenuitive.

I like the way DIY guys always tell each other their ideas.

Neat concept, but it's only good for one size and model of bearing. Next time just weld two hot passes inside the bearing or race. The weld will shrink and contract it so that it falls out on its own when you flip it over. Takes no time at all.

It's incredible and there's not an hour of unnecessary talk. 🤔👍

I love these types of videos. There's always someone that has a different technique to solve a problem. I've only used the weld to shrink method and its always worked. Mind you I'm a backyarder with my own motorcycles, so i haven't needed to use different techniques often.
Love your work mate, i really do!

Hi guys. It seems everyone has missed the simple method. Apply a few blobs of weld to the inside of the bearing. Wait 1 minute, the welds will shrink. As the welds are attached to the bearing, the bearing will also shrink. The bearing will fall out. You can use this method on engine cylinder liners. Ore small line of weld. The liner will fall out. Done it thousands of times.

Genius sir! All without the need for heat that can distort the other materials

When I first started working on cars and trucks I had an older mechanic teach me how to do this. I ve used this method several times and it works every time.
