Continental AG says that elastic multi v-belts are becoming increasingly popular in the engines of today’s automobile, and its ContiTech Power Transmission Group suggests that professional repair technicians take note of key tips that will help replacement and earn the customers’ confidence and loyalty.
Elastic Multi V-Belts from ContiTech maintain tension themselves, and do not require any additional tension take-up, which reduces the costs of the drive. However, ContiTech recommends a few special features be taken into account when changing these elastic belts. Power transmission specialist ContiTech Power Transmission Group has summarized the key tips.
Elastic belts power the ancillary components and are suitable for drives in the lower and medium output ranges wherever there are fixed center distances. Even if the dimensions are identical, under no circumstances may standard Multi V-belts be used where elastic belts are required.
“The latter do not stretch and therefore do not apply the necessary initial tension to the belt pulleys -- or cannot even be fitted in the first place,” says ContiTech’s Markus Pirsch of the Power Transmission Group.
“Changing the belt requires a certain force since elastic belts have to be stretched when being fitted. Special tools are therefore always required to ensure correct fitting. It is essential not to resort to other fitting methods involving, for example, the use of a screwdriver or other tools which are not fit for purpose.
“Not just because the belt and pulley can be damaged in the process, but also because there is the risk of injury to the installer.”
ContiTech says it supplies Elastic Multi V-Belts to almost all major automakers. To ensure safe, correct replacement, the company offers elastic belts together with a disposable tool in a complete kit for the automotive aftermarket for many vehicle types.
The kits, whose quality matches that of the original equipment, meet the specifications of the vehicle manufacturers. Additionally, all the elastic belts in the range are also available individually.
In the case of vehicle types for which no kit is available, ContiTech recommends its special tools.
“The Uni Tool Elast is especially versatile since it is also suitable for flat belt pulleys without any indentation, with the exception of double pulleys of the same diameter,” explains Pirsch.
ContiTech also offers the ELAST TOOL F01 with the above-mentioned double belt pulley for fitting the alternator belt, which cannot be installed without this special tool.
