• North America produces or imports 16 million vehicles a year

– 20% of these vehicles have Timing Belts

3.2 Million New Customers

Timing Belts

3

95% of all general repair shops perform Timing Belt installation

•4 out of every 100 cars serviced will have their timing belt replaced

•Average timing belt replacement is on a car 5 years or older with 68K miles

Timing System Labor Claims

Timing Belt system failure = expensive engine damage

Up to 40% of timing belt failures are caused by idler, tensioner failure

Comebacks kill profitability and productivity of installers

Minimum additional dollars to replace all system components utilizing a Timing Belt Kit (TCK)

6

Timing Systems – Warranty Reductions

• Benefits of Kits – “Do it Once, Do it Right”

– Replacing all “system” components is the absolute best practice

– All moving parts are susceptible to failure

– Bearings are filled with grease that over time leak, increasing friction leading to failure

Second Question Is:

Is your engine interference or

non-interference?

TCK Job Economics Analysis

1999 Dodge Grand Caravan 3.0L engine

Belt replacement costs• Labor 4.2 hours @ $85 = $357• Parts – T139 belt @ $67• Total cost = $424

Difference of $61Timing Component Kit replacement costs

• Labor 4.4 hours @ $85 = $374• Parts – TCK139 kit @ $111• Total cost = $485

• Tensile Failure

If the cover isn’t correctly positioned, foreign materials may get in the drive and damage the belts. Excessive installation tension, or damage to the tensile cord due to improper handling before or during installation, also causes tensile failure.

Causes of Premature Belt Failure

15

Tooth Shear

Not enough tension, or seizure of the driven part will cause tooth shear

Causes of Premature Belt Failure

16

Tooth Wear

Results from incorrect tension, or a worn sprocket

Causes of Premature Belt Failure

17

Back Cracks

Excessive temperatures under the hood, or extreme cold, contribute to cracking

Causes of Premature Belt Failure

18

Land Wear

Wear between the teeth is caused by rough sprockets or excessive tension

Causes of Premature Belt Failure

19

Oil Contamination

Faulty oil seals may cause oil to leak on the belts

Absolutely NO oil contamination on these belts!!!

Causes of Premature Belt Failure

20

Edge Wear

Sprocket flange damage, or misalignment lead to edge wear.
