Frequently Asked Questions
6397 supports the gearbox mainshaft by housing and guiding the needle rollers, providing radial support and smooth rotation in the manual transmission. If the bearing becomes worn or damaged it can produce whining or rumbling noises and allow excess play on the mainshaft, which accelerates gearbox wear. Inspect the bearing during transmission service and replace if roughness, noise or excessive play is detected; ensure correct seating and lubrication at fitment.
