Recommended Tool
If you are looking for the tool to easily remove the spring pin holding the gear in place be sure to check the option above to add the 5/32" roll pin tool. It is the best tool to easily remove the pin without damage. It also reduces the chance for injury when driving out the gear with improper tools. Reminder to always wear safety glasses when using striking tools.

Door opener gear
Except for my own clumsyness, worked well and the parts very reasonable. I would suggest a good diagram of where each part goes as I had to replace the top bushing also. After putting in in realized I had put the bushing wrong and had to take it part again. Also how tight to have the chain or belt. Happy now

I'm a mechanic/retiree/renter/d.i.y.
The parts were affordable: came quickly: included everything necessary: instructions were vague only because they didn't specify use of included grease i.e.., how much and where.I'm real pleased and would order from this company again!

Craftsman gear was a great site to order from. I found the part I needed within 30 seconds on the web-site, placed my order at 11:00 on a Saturday night, and Tuesday when I got home from work the parts were in my mailbox. And that was with the cheapest shipping option.
