The ATC 3164088 Cam Bearing Adaptor & Installation Kit delivers precision removal and installation of cam bearings on Cummins ISX, QSX, ISX15, and QSX15 engines (not ISX12). Includes adaptors + 24″ & 55″ driver bars for full reach and alignment—prevents bore scoring and damage in heavy-duty rebuilds.

The Critical Risks of Improper Cam Bearing Service in Cummins ISX/QSX Engines

Cummins ISX15 and QSX15 engines power heavy-duty trucks, but damaged cam bearing bores from improper tools lead to oil starvation, cam failure, and catastrophic engine damage.

• Bore scoring – Improper drivers mar housings, requiring $1,500–$4,000 line boring
• Bearing distortion – Misalignment crushes bearings, costing $1,000–$2,500 replacements
• Cam damage – Uneven force scores lobes, leading to $2,000–$5,000 camshaft repair
• Downtime losses – Manual struggles extend service 3–6 hours, adding $600–$1,200 labor
• Oil starvation – Damaged bores block flow, totaling $3,000–$7,000 bearing failures
• Engine rebuild – Severe damage demands full overhaul ($8,000–$18,000)
