Technical Bulletin 197 Issue 1 3 of 9 Item: 197.2 Description: Steering Head Bearings - Adjustment Model Affected: Scrambler 1200 XC, Scrambler 1200 XE The procedure for the adjustment of the steering head bearings on the above models has changed. A new service tool (T3880750) must be used to complete this operation. When you adjust the steering head bearings, follow the procedure described below. Warning Make sure the motorcycle is stabilised and adequately supported. A correctly supported motorcycle will help prevent it from falling. An unstable motorcycle may fall, causing injury to the operator or damage to the motorcycle. 1. 2. Remove the seat as described in the Service Manual. Disconnect the battery as described in the Service Manual. Warning If the lower yoke fixings are also loosened, the forks will no longer support the weight of the motorcycle. Do not loosen the lower yoke fixings as, in this condition, the motorcycle could topple over causing damage and/or risk of injury. 3. 4. Remove the upper yoke as described in the Service Manual. Adjust the bearing free play as follows: • Use service tool T3880023 to remove the lock nut. • Remove the tab washer. • Use service tool T3880023 to remove the adjuster nut. • Thoroughly clean the threads on the steering stem. • Refit the adjuster nut and tighten to 40 Nm. • Loosen the adjuster nut, then tighten to 15 Nm. • Fit the tab washer. • Fit the lock nut. Warning It is essential that the adjuster nut is not over-tightened. If the adjuster is over-tightened it will cause a pre-load on the headstock bearings. This will introduce tight steering, which could cause loss of motorcycle control and an accident. Technical Bulletin 197 Issue 1 4 of 9 • With the bearing free play correctly set, use service tool T3880750 to hold the adjuster nut stationary, then use service tool T3880023 to tighten the lock nut to 40 Nm. 1 2 3 5 4 cjbu 1. 2. 3. 4. 5. T3880023 - 50 mm Socket Lock nut Tab washer Adjuster nut Dust seal Warning Make sure you torque the adjustment nut in an anticlockwise direction in the step that follows. If you do not, the headstock bearings can become loose. Note: • Keep the torque wrench at 90 degrees to the centre line of the tool when you tighten the adjustment nut in the stage that follows. This will apply the correct torque to the adjustment nut. • Use service tool T3880750 to tighten the adjustment nut in an anticlockwise direction to 45 Nm. Keep the torque wrench at 90 degrees to the centre line of the tool. Technical Bulletin 197 Issue 1 5 of 9 Note: • The adjustment nut can turn up to 90 degrees when you tighten it anticlockwise. This is usual. 1 2 90° 1. 2. T3880750 - Headstock service tool Torque wrench Warning Operation of the motorcycle with incorrectly adjusted steering head bearings, either too loose or too tight, may cause a dangerous riding condition leading to loss of motorcycle control and an accident. 5. Check that the free play has been eliminated and that the steering can be turned freely from lock-tolock without any sign of tightness. Readjust if necessary. 6. Install the upper yoke as described in the Service Manual. 7. Connect the battery as described in the Service Manual. 8. Install the seat as described in the Service Manual. Please mark your copy of the Service Manual with this information. For electronic service manuals, store this information in a readily accessible place and refer to it often. This information will be included in the next service manual update. Technical Bulletin 197 Issue 1 6 of 9 Item: 197.3 Description: Gear Change Selector Mechanism Kit Model Affected: Street Cup, Street Twin, Bonneville T100 models from VIN 759204, Street Scrambler, Thruxton 1200, Thruxton 1200R, Bonneville T120 models, Bonnevile Bobber, Bonneville Speedmaster from VIN 739143 and Bonneville Bobber Black A gear change selector mechanism kit has been introduced for the above models and is retrofittable to the start of production. Parts will no longer support the old condition gear change selector mechanism or the individual components included in the kit, and any replacement will be to the new condition. Parts kit T1191968 has been released for use when replacing the gear change selector mechanism kit. The kit consists of a fully assembled selector mechanism. Note: • The washer at the splined end of the selector shaft is retained by an O-ring for transportation purposes. The O-ring must be removed and discarded before installing the selector shaft. 1 1. O-ring When ordering replacement parts, refer to the EPC. Please mark your copy of the Service Manual with this information. For electronic service manuals, store this information in a readily accessible place and refer to it when working on the relevant Triumph motorcycle. This information will be included in the next service manual update. Technical Bulletin 197 Issue 1 7 of 9 Item: 197.4 Description: Fork Seal Cleaner Model Affected: All models The following service tools have been introduced to clean the front fork oil seal: • T3880215 - Fork Seal Cleaner, Small • T3880216 - Fork Seal Cleaner, Large Service tool T3880215 is to be used on front suspension forks with a diameter between 35 to 45mm. Service tool T3880216 is to be used on front suspension forks with a diameter between 45 to 55mm. To clean the oil seal and dust seal, follow the procedure described below. Warning Make sure the motorcycle is stabilised and adequately supported. A correctly supported motorcycle will help prevent it from falling. An unstable motorcycle may fall, causing injury to the operator or damage to the motorcycle. 1. 2. Clean the area around the dust seal then carefully detach the dust seal from the fork outer tube. Wipe away any visible dirt or water from the oil seal. Note: • • 3. 4. The fork seal cleaner has two cleaning hooks. The one with the OIL SEAL text is for the oil seal, the other cleaning hook is for the dust seal. When cleaning the oil seal with the fork seal cleaner it is possible that a small amount of fork oil may seep out. Clean the fork seal cleaner before use. Fit the fork seal cleaner to the fork inner tube. Make sure that the cleaning hook, with the text OIL SEAL below it, is pointing towards the oil seal. 3 1 2 ckpd 1. 2. 3.
