|WARNING - LOTUS SPARES ARE EXPENSIVE
Here's a just little advice to help you stretch the cost:
Lotus A100E6170S (£49.00)
Isuzu 894429-4860 - 1" x 50 3/32" (159 Teeth)
Dayco 95169 (North America part no.) or 94197 (Europe part no.)
Dayco Europe information on timing belt markings
There are white and yellow markings, written along the belt. I will get a photo when I can to better demonstrate how the markings appear on the belt.
DAYCO 159 SHP PLUS 254 H ISORAN (R) 159 RHP PLUS 254 H 94197
Is the model identifier. Specifically 94197 is the part number when you're looking for a replacement belt.
06 134041 06 134042 06 134043 06 134044 06 134045
The first two digits are the year of manufacture, followed by two digits for the week then a digit for the day of the week, then there are three digits indicating the position on the production mould. So in this case the belt was made on the 4th day of the 13th week of 2006.
They recommend NOT fitting any belt that is more than ten years old. However, if a belt is fitted before the belt is ten years old then the manufacturer's service interval still holds, in the case of the Elan 5 years (60 months) or 60000 miles, whichever comes first.
