Although Tuthill Vacuum & Blower Systems blowers are well designed and manufactured, problems may occur 
due to normal wear and the need for readjustment. The following chart lists symptoms that may occur along 
with probable causes and remedies.

SYMPTOM

PROBABLE CAUSE

REMEDIES

Loss of oil

Gear housing not 
tightened properly

Tighten gear housing bolts.

Lip seal failure

Disassemble and replace lip seal.

Insuf

¿

 cient sealant

Remove gear housing and replace sealant. 

See Disassembly 

of Blower on page 30

.

Loose drain plug

Tighten drain plug.

Excessive 
bearing or gear 
wear

Improper lubrication

Correct oil level. Replace dirty oil. 

See Lubrication on page 

15

.

Excessive belt tension

Check belt manufacturer’s speci

¿

 cations for tension and adjust 

accordingly.

Coupling misalignment

Check carefully. Re-align if necessary.

Lack of volume

Slipping belts

Check belt manufacturer’s speci

¿

 cations for tension and adjust 

accordingly.

Worn lobe clearances

Check for proper clearances. 

See Assembly Clearances on 

page 40

.

Speed too low

Increase blower speed within limits.

Obstruction in piping

Check system to ensure an open 

À

 ow path.

Knocking

Blower out of time

Re-time.

Distortion due to 
improper mounting or 
pipe strains

Check mounting alignment and relieve pipe strains.

Excessive pressure 
differential

Reduce to manufacturer’s recommended pressure. Examine 
relief valve and reset if necessary.

Worn gears

Replace timing gears.
