Detailed Description

Rotomaster M1020301N is intended for turbocharger rebuilds where the housings remain serviceable and the internal damage is limited to normal wear items. The kit includes a thrust bearing, thrust flinger, collar, piston rings, O-rings, nuts, and gasket, giving technicians the core service parts needed to restore turbocharger function. Because it is a specific application kit, it supports accurate repair work on BMW turbocharged models rather than a universal one-size-fits-all solution.

The Rotomaster New Turbocharger Service Kit product line focuses on cost-conscious turbo repair by replacing serviceable wear components instead of the full turbocharger assembly. Part number M1020301N is also referenced as a direct interchange for N102301K.

Common Repair Uses

• Turbocharger oil leakage from worn sealing components
• Excess shaft play caused by worn bearings or thrust parts
• Loss of boost performance from worn service components
• Turbo rebuilds where the center, compressor, and turbine housings can be reused
• BMW turbocharger maintenance on listed 135i, 335i, 535i, and Z4 applications

Installation Notes and Tips

Inspect the turbocharger carefully before installation. This kit is appropriate when the internal components are serviceable and the housings can be reused; if the turbocharger has sustained internal damage, additional repair or replacement may be required. Clean all mating surfaces thoroughly, verify part numbers against the vehicle application, and follow the turbocharger manufacturer’s rebuild procedures during assembly. Confirm fitment for the exact BMW model and year before ordering.

Quality Assurance

Rotomaster supplies O.E.-grade, direct-fit service components for a precise repair-focused rebuild. The kit is packaged new and organized in a transparent case for easier handling during service work.
