HERTH+BUSS JAKOPARTS clutch kit (J2002059) restores clean gear changes and full torque transfer by replacing the friction disc, pressure plate, and release bearing as a matched assembly — eliminating the judder and slip that worn components cause. The assembly is rated for Number of Teeth: 21, Supplementary Article/Info 2: 523, for bearing clearance from [mm]: 24 mm, Friction Lining Outer Diameter [mm]: 212 mm, with the friction disc compound chosen to match the torque output of the engine and resist glazing under the stop-start urban driving cycles where clutches wear fastest. Spline count, disc diameter, and diaphragm spring load are matched to the gearbox input shaft on TOYOTA models for a bolt-on installation requiring no machining of the flywheel face. Replaces OE clutch references: 134547, 3000 771 001, 3000 951 758, 622 1145 60 and 32 more. HERTH+BUSS JAKOPARTS drivetrain components are dynamometer-verified for torque capacity before leaving the factory and are supplied with installation lubricant and alignment tools in the kit. Clutch lifespan varies widely — from 30,000 miles in heavy urban traffic to 100,000+ miles with smooth driving habits — but any manual-gearbox vehicle will eventually need a clutch replacement. Common symptoms of clutch wear include a slipping clutch (engine revs rising without a corresponding increase in speed), a biting point that has moved high in the pedal travel, judder when pulling away, and difficulty selecting gears. Clutch replacement is a significant job that requires gearbox removal — most DIY mechanics will need a transmission jack, an engine support bar, and a full set of sockets; allow a full day for the work. Always replace the complete clutch kit (disc, pressure plate, and release bearing) together — fitting only one component means the gearbox must be removed again when the remaining parts wear out shortly afterwards. Addressing clutch slip early prevents flywheel damage from overheating — a resurfaced or replaced flywheel adds substantial cost to a job that is already labour-intensive, so prompt replacement saves money.
