Coupler/Isolator:

The coupler/Isolator is the part that transmits drive between the snout and the rotors. There are two different types, a sprung type and a solid version both supplied by Eaton. Within our services we are increasingly see the sprung version failing making a clattery idle from the supercharger and physical damage to the snout shaft as the spring rubs. This can be checked by uncoupling the supercharger belt and trying to rotate the pulley. With a brisk rotation each way you should get minimal spring effect, approx 2mm of variance. If the variance is greater and feels softer then the coupler will be worn and need replacing. If this is so please check our range of stock sprung, eaton solid and aftermarket couplers available for your car. A coupler is NOT included in this sale, we do offer a kit with our uprated coupler included or sprung couplers, solid eaton, uprated and drive hubs all seperate for you to purchase if you find you need them.

Bearings:

Snout bearings are one of the most common element to wear out on a supercharger as they are taking the undamped strain of the drive belt. Fortunately with a few workshop tools such as a hydraulic press and if needed a blow lamp they can be replaced with this kit. A major sign that your bearings might need to be replaced is a rattle and rumble from the supercharger at idle. When worse excessive supercharger noise can be heard showing a sign of futher case bearing failure, typically in these superchargers the main drive through bearing to the rotors (included in this sale).

Supercharger Oil:

Most motor manufacturers overlook the strain placed on oil by high rotational speeds of superchargers and treat the oil as being filled for life – this is not good practice! Often, by 40 or 50,000 miles and certainly at higher mileages, the oil can come out like old gravy. Of course, that’s usually long past the time that warranties have run out – but by this time the vehicle makers are unconcerned.

To preserve supercharger life, the oil needs changing and we recommend this is done by no later than 40,000 miles.

Rebuild Services:

If you not have the workshop tools required or simply do not wish to undertake the task yourself Powerhouse also offer rebuild services for snouts to whole superchargers. Please see our other items for our rebuild services.
