What to do if my LFA TDP 6s Power Tool is making knocking sounds?
- JJill WilliamsAug 25, 2025
Knocking sounds from your LFA Power Tool can stem from several issues. The Upper and Lower Punches might be colliding with the Die; realign the Base Plate after loosening its bolts and then tighten them back. A slightly off Upper Drift Pin Assembly can also cause this; loosen the Base Plate bolts, rotate the machine until the Upper Punch aligns with the Die's bore, and then tighten the bolts. Check the V-belts and tighten the Motor Support Arm's nuts to adjust the V Belts (correct tension for run-in belt is [N] 92.47). Inspect the Pinion Gear and/or Cam Drive Cog for broken teeth and replace if necessary. Also, ensure there isn't powder buildup between the Lower Punch and the Die, and that the Lower Drift Pin Assembly has enough clearance.
