Why is my Tuthill Blower overheating?
- P
  Peter WilliamsAug 1, 2025
  Several factors can cause a Tuthill Blower to overheat. It could be due to too much or too little oil in the gear reservoir, so check the oil level. The operating speed might be too low, and increasing the blower speed within limits could help. A clogged filter or silencer can also cause overheating; remove any obstructions. Excessive pressure differential can be another cause, so reduce the pressure differential across the blower. Elevated inlet temperature and worn lobe clearances may also lead to overheating, so reduce the inlet temperature and check for proper clearances.

How to fix lack of volume in Tuthill Blower?
- A
  Adrienne WilcoxAug 5, 2025
  A lack of volume in your Tuthill Blower can stem from several issues. Slipping belts could be the culprit, so check the belt manufacturer’s specifications for tension and adjust accordingly. Worn lobe clearances might also be the cause; check for proper clearances. Ensure the blower speed isn't too low, and increase it within limits if necessary. Finally, check the system for any obstructions in the piping to assure an open flow path.

How to stop oil loss from Tuthill Blower?
- N
  nicole78Aug 10, 2025
  Oil loss in your Tuthill Blower can occur for several reasons. Ensure the gear housing is tightened properly by tightening the gear housing bolts. A lip seal failure could also be the cause, requiring disassembly and replacement of the lip seal. Insufficient sealant can lead to leaks; remove the gear housing and replace the sealant. Lastly, check for a loose drain plug and tighten it.

What to do if Tuthill Blower is vibrating?
- C
  Carolyn EricksonAug 14, 2025
  If your Tuthill Blower is vibrating, several factors could be responsible. Check for belt or coupling misalignment and realign if necessary. Lobes rubbing against each other can also cause vibration; inspect the cylinder for hot spots and check for lobe contact at these points. Worn bearings or gears may be the issue, so check their condition and replace them if needed. Unbalanced or rubbing lobes due to buildup on the casing or lobes could also be the cause; remove any buildup to restore clearances. Ensure the driver or blower isn't loose by checking the mounting and tightening if necessary. Finally, piping resonance can contribute to vibration; check pipe supports, the resonance of nearby equipment, and the foundation.

Why is my Tuthill Blower knocking?
- C
  cschneiderAug 18, 2025
  A knocking sound in your Tuthill Blower can indicate several problems. The unit might be out of time, requiring you to re-time it. Distortion due to improper mounting or pipe strains can also cause knocking, so check the mounting alignment and relieve any pipe strains. Excessive pressure differential can be another cause; reduce it to the manufacturer’s recommended pressure. Finally, worn gears might be the issue; examine the relief valve and reset it if necessary, and consider replacing the timing gears.

What causes excessive wear on Tuthill Blower bearings and gears?
- L
  Laurie JohnsonAug 22, 2025
  Excessive wear on the bearings or gears of your Tuthill Blower can be attributed to a few key factors. Improper lubrication is a common cause, so ensure the oil level is correct. Excessive belt tension can also lead to wear; check the belt manufacturer’s specifications for tension and adjust accordingly. Lastly, coupling misalignment can contribute to the problem, so check carefully and realign if necessary.

How to fix rotor drag in Tuthill Blower?
- C
  Chad Ibarra PhDAug 27, 2025
  Rotor end or tip drag in a Tuthill Blower can result from several issues. Insufficient assembled clearances may be the cause, so correct the clearances. Case or frame distortion can also lead to drag; check the mounting and pipe strain. Additionally, excessive operating pressure or temperature can contribute to this problem; reduce the pressure differential or reduce the inlet temperature.
