4.9 Power Feed Mechanical Test
1. Remove the weight from the track rollers. They should turn smoothly and easily with very
little play.
2. Make sure the middle track cover is not bent or touching the top rail.
3. Make sure the middle track oiler, if applicable, is free of sawdust buildup.
4. Make sure the power feed chain is not stiff from rust. Also make sure the chain is not too
tight.
5. Check the power feed shaft. Visually inspect the bearings. The shaft should move neither
in or out nor side to side.
6. Make sure the power feed chain cam bearing is not touching the main frame tube.
7. If you have an old-style mill with loop-designed feed chain, inspect the front and rear
sprocket assemblies. Make sure there are no defective bearings.
8. Make sure there is no sap or rust on the rails.
9. Make sure the block on the lower track roller assembly is not rubbing the lower rail. Also
make sure the track rollers are not too tight.
10. Make sure the power feed belt is properly tightened.
