Metal Transmission Gear Kit, Mini Lathe & 3MT Mini Mill, LittleMachineShop.com (3448)

Metal replace drive gears fit and worked perfect.Thank you!

Easy-ish to install. Works well. Much stronger than the plastic gears. What were they thinking?

I own a Harbor Freight mini metal lathe and after many years of use I managed to strip those notorious nylon transmission gears. I bought these replacements hoping I could talk a proper mechanic into installing them. But to no avail. So I undertook the task of doing it myself. Armed with several videos online showing how and a modest collection of common hand tools I completed the task in under 4hrs. A concentricity gauge showed I did the job right. I now own a fully functional and more robust lathe. Note: These are metal and require regular maintenance (greasing) so do consider drilling grease ports in the gearbox housing.

The gears look very good, I had to debur a bit the wire brush did a good job. I have not installed ten yet, I am waiting on the new bearings.

nice finish, replaced plastic gears making lathe much quieter, and able to take deeper cuts.

Had an issue with the smaller transmission gear having some messed up teeth. Caused the lathe to bind when placed in low gear. Contacted the seller and they shipped a replacement immediately without question.Metal gears do make the lathe louder but it’s better than having to completely disassemble the machine in order to replace broken plastic ones.Little Machine Shop is top notch for home machinists/hobbiests.

A little noisy but worked great.

I bought this after some research and decided that it likely would fit our Grizzly G0781 mini mill. It did fit and runs flawlessly. Great bargain. Same cost as plastic gears but they don't break! Awesome!
