Professional 13-piece alternator pulley removal and installation kit for OAP and OAD type pulleys on modern vehicle alternators.
The KEAA 13 PC Alternator Pulley Kit is a professional workshop tool set for removing and installing overrunning alternator pulleys (OAP) and overrunning alternator decouplers (OAD) on modern vehicle alternators. These pulleys are friction-press fitted on the alternator shaft with extremely high torque and cannot be removed with a standard spanner — attempting to do so damages the alternator shaft or pulley. The kit provides 13 matched adaptors and holding sockets that cover the most common OAP and OAD configurations found in European, Japanese, Korean, and Indian vehicle fleets.
In vehicle workshops across Guwahati — in Bhangagarh, Sixmile, Lokhra, and along the NH-37 workshop strip — alternator pulley bearing failures are a common cause of belt tensioner noise and serpentine belt wear. Correctly removing and reinstalling OAP and OAD pulleys without the right tool set takes far longer, risks shaft damage, and can result in a mis-installed pulley that causes belt failure. The KEAA kit gives technicians a fast, professional solution.
Multi-bay vehicle service workshops handling modern Indian and imported vehicles are the primary users. Fleet maintenance workshops for commercial operators — goods transport companies, bus fleets, government vehicle pools — encounter OAP pulleys on Euro IV and Euro VI engine alternators in Tata, Ashok Leyland, Bharat Benz, and Eicher trucks. These vehicles make up a large share of road freight across Assam, Meghalaya, and Arunachal Pradesh.
The kit pairs with the KEAA bearing puller set for complete alternator overhaul work, with a digital multimeter for charging system diagnosis before teardown, and with an alternator test bench for output verification after repair. Keeping the complete alternator repair tool set on hand lets a workshop handle alternator rebuilds in-house rather than outsourcing to a specialist.

The KEAA 13 PC Alternator Pulley Kit is designed for overrunning alternator pulleys (OAP) and overrunning alternator decouplers (OAD) — the one-way clutch pulleys found on the alternators of modern cars and light commercial vehicles. These pulleys allow the alternator to freewheel during engine deceleration, reducing belt drive vibration and increasing belt life. They are pressed on to the alternator shaft with a very tight fit and cannot be removed with a standard spanner; the kit provides the correct holding and turning tools for each major alternator brand.
Most KEAA alternator pulley kits cover both OAP (simple overrunning, one-way ratchet) and OAD (overrunning with internal torsional spring damper) variants. The difference in removal technique is that OAD pulleys must first be compressed slightly before they release from the shaft — the kit includes the correct compression adaptor. Using the wrong tool can damage the OAD's internal spring, which then requires full pulley replacement rather than a simple bearing swap. If in doubt, identify the pulley type from the vehicle workshop manual before selecting the tool. Call or WhatsApp us with the vehicle make and model for assistance.
