Norco Range 2018 Pivot Bearings: Request the Correct Parts by Position

Norco Range 2018 pivot bearings should be requested by their position in the frame, not as one anonymous bag of bearings. The historical documents distinguish dropout, main-pivot and linkarm assemblies, and include shafts and spacers around the bearings. They also contain differences that a careful parts enquiry should expose rather than conceal.

Map the Norco Range 2018 pivot bearings to the drawing

The 2018 assembly document (https://www.norco.com/downloads/bike-tech-sheets/range-carbon-frame-assembly.pdf) starts with a frame diagram and lettered locations. Its rear-pivot drawing uses a 6901 bearing kit with 12 × 24 × 6 mm dimensions. The main-pivot drawing uses a 6902 kit with 15 × 28 × 7 mm dimensions. Those entries already show why ordering every bearing by a single familiar designation is insufficient.

The drawings also identify spacers and shafts separately. A bearing replacement request should say which joint is being inspected, what play or damage prompted the inspection, and whether the surrounding hardware is present and serviceable. Bearing dimensions alone do not establish that the correct spacers, shaft and retaining pieces are included in a proposed package.

Flag revisions before accepting a kit

The 2018 drawing gives 913600-000 for the main-pivot shaft and nut. The 2018–2019 revision (https://www.norco.com/cmsb/uploads/bikes/bikes/range-carbon-tech-support_003.pdf) instead shows 913600-009 at that location, and the detailed 2018 specification table (https://www.norco.com/downloads/bike-spec-sheets/range-carbon-small-parts.pdf) also lists the latter code in its BB-pivot package. These are documented differences. The available sheets do not establish that one number universally supersedes the other or that both kits fit every individual frame.

There is another reason to keep the actual drawings with the enquiry: the detailed table's seatstay/linkarm bearing wording does not line up cleanly with all the numbered bearing labels in the assembly illustrations. Do not combine convenient lines from different sheets into an asserted complete kit. Ask the retailer to confirm the joint, correct revision and contents against the actual frame.

A useful request includes the claimed model year, C7 or C9 identity, photographs of the joint and existing hardware, and the relevant document page. Describe a missing spacer explicitly rather than expecting the supplier to infer it from a bearing code. Any proposed replacement should be confirmed as a set of parts for that location, with quantities and included hardware stated.

The setup document calls for inspection of bearings and pivot hardware every 30 riding hours, with replacement of concerning components by a qualified technician. That inspection interval is not a promise that bearings last a set number of hours, and it is not the fork or shock manufacturer's damper-service schedule.

FAQ

Are the rear-pivot and main-pivot bearings the same size?

No. The drawings identify 12 × 24 × 6 mm 6901 bearings and 15 × 28 × 7 mm 6902 bearings at those respective locations.

Can the -000 and -009 shaft codes be treated as interchangeable?

The sheets do not establish that equivalence; ask the retailer to confirm the correct part for the actual joint and frame.

Does a bearing code describe the whole hardware kit?

No. Shafts, spacers and retaining pieces must be identified and checked separately.

The rear-axle identification guide deals with the wheel interface rather than linkage bearings. Keep that distinction clear when using the historical resources under Norco bicycles.
