REPXPERT issues new INA technical bulletins
Home   
Wednesday, June 13, 2018
The REPXPERT technical team has released some new and useful service information about the latest design changes and product updates from Schaeffler.

All three releases concern INA components, the first relating to an improved coolant pump design that affects many Fiat Group and General Motors diesel applications. The addition of a heavy duty external bearing, to replace the former standard version, is designed to cope better with temperature fluctuations, load changes and vibration levels in the timing belt system and therefore extend the service life of the pump.

The next bulletin focuses on tensioner pulley and vibration damper combinations. Whilst some part pairings may appear to match correctly, INA engineers are advising technicians to carefully check the specified tensioner pulley and vibration damper to ensure they are going to install the correct pairing.

Tensioner pulley and vibration dampers are engineered to work together, so only the correct combination will guarantee the smoothest possible engine timing. A mix of parts could cause increased wear or even failure of individual timing system components. It is best practice is to always follow accurate vehicle manufacturer (VM) recommended installation instructions and specifications, which are available to download for free on REPXPERT.

The final bulletin concerns the inclusion of a diamond-encrusted washer in some INA Timing Belt KITs to suit a variety of Audi, Volvo and Volkswagen 2.5TDi applications. VM installation instructions include the removal of the crankshaft vibration damper during a belt system service. VAG and Volvo both recommend that the crankshaft bolt, and its diamond-encrusted washer, should be replaced during this procedure, so INA now includes these components in all applicable KITs. The special coating on the washer, combined with the new crankshaft bolt, eliminates the chances of the vibration damper becoming loose during operation.

These three bulletins, along with service information sheets for all the Schaeffler brands, LuK, FAG and Ruville, are available to view and download from REPXPERT. It is simple, quick and free to register. Not only can users brush up on their technical skills, but they can watch installation videos, take part in online training sessions or sign-up to the latest live training events at the REPXPERT Academy.
