Easy fix for Makita 2040 planer , two screws on the cover and snap rings that hold the sprocket on , a spring loaded tensioner keeps the chain tight . If you are replacing worn chain and sprockets the 2040 requires three sprockets , one on drive and one on each feed roller .

Sprocket broke, shaft on main drive roller broke, plane bearing worn through, and metal cover S broke.

Difficulty

Time
1-2 hours
Tools Used
Screwdriver, Pliers, Hammer, jack, file
Removed old roller, bearing, sprocket, and metal cover, that holds the roller in place, and replaced them with new ones. I used a car jack to hold the roller in place while I put the springs, bearings and roller back in place. Then I replace the sprocket, oiled the chain and clean everything. It is working great. This is a Makita 15 inch model 2040 planer. The new sprocket was hard to get back on. I had to do some minor filing. Using the car jack and a piece of wood freed my hands to get the springs, bearings, and roller back in place. I have had this planer for about thirty years.
