New alternator tool kit from Laser Tools

Overrunning alternator pulleys are becoming increasingly popular on many modern passenger cars and light commercial vehicles due to increased alternator loads. As opposed to traditional solid pulleys, they allow the alternator to free-wheel or overrun every time the engine decelerates and, at the same time, dampen vibrations at the alternator.

Like any other part, overrunning alternator pulleys don’t last forever, and this is now a common replacement part. Proper tools are needed when working on these pulleys, and this new kit from Laser Tools (part number 7052), distributed in Ireland by Tech ‘n’ Tools, brings together the tools needed to remove and install the pulleys on Nippon Denso, Valeo, Bosch and Marelli alternators.

The kit is comprehensive, and includes three half inch drive combination drivers: an M10 spline driver with a 31 spline with 15mm hex, a 10mm female hex with a 17mm outer hex and a T50 star combined with 31 spline with 15mm hex. Three sleeves: 32mm male hex with 3-pin drive, 33 spline drive x 15mm hex (outer) and a 28mm male hex x 15mm male hex drive. A half inch drive 10mm bit holder is included, along with a half inch drive 10mm 12-point socket. The kit also features three 75mm long 10mm bit drivers, manufacturer from tough, shock-resisting S2 steel: an M10 spline, an 8mm hex and a T50 star.

Two double-ended ring spanners are included, both featuring a standard ring plus a handy ratchet ring; the 10mm spanner is 275mm long, and the 15mm spanner is 345mm long, useful lengths for reaching down into the engine bay. A 10mm to 8mm hex adaptor finishes the list.
