In the Tool Talk Podcast #38, a caller asked about replacing the chuck on his Skil hammer drill. Though Chuck and Sean weren’t able to answer his questions on the spot, I found some answers at eReplacementParts.com, which boasts the Internet’s largest selection of power tool diagrams and replacement parts . By looking at a diagram on their site, I found that the chuck in question is standard-thread and removable. Also, before you can remove the chuck, you have to remove a securing screw that goes down the middle of the barrel.
I also turned to eReplacementParts to help out a buddy of mine who owns a granite countertop shop — he was throwing away high-end Makita grinders every month because they were wearing out after long periods of use. I told him to save the next ones for me to look at before throwing them away. After opening one up, I quickly found that the bearing casings were breaking apart, causing the grinder to shake violently.
So I went to eReplacementParts.com, entered the model number, found the part, and ordered ten new bearings, which arrived in a timely manner. With a little work and a trip to the auto parts store to buy compression-ring pliers, I installed the new bearings and put the three grinders back together. Now they purr like new — and the six dollar bearings were a lot cheaper than buying new $130-plus Makita variable speed grinders.
Next time you have a power tool breakdown, try fixing it. It’s fun, and you’ll learn a lot and save some serious money in the process.
