To remove the transmission, start by removing the clutch pressure plate from the flywheel. Make sure to catch the clutch friction disc as it may drop out. Inspect the clutch disc for any damage or wear, and replace it if necessary. Check the flywheel for cracks or damage, and resurface it if needed. Replace the release bearing along with the clutch disc. Clean all surfaces and ensure there is no oil or grease. Position the disc on the flywheel with the correct side facing out. Use a tool to center the friction disc. If reusing the original pressure plate, use a special tool to compress the diaphragm spring and reset the self-adjusting mechanism. Install the clutch cover assembly, aligning the marks if applicable. Tighten the mounting bolts to the specified torque. Remove any tools used and install the transmission.

Removal begins with the removal of the transmission. The Clutch Fork is then slid sideways to release it from the retaining spring clip and pivot, then the Fork and bearing are pulled forwards from the guide sleeve. It is important not to detach the release bearing from the Fork as they are only available as a complete assembly. Inspection involves spinning the release bearing and checking it for excessive roughness. Holding the outer race, attempt to move it laterally against the inner race. If any excessive movement or roughness is evident, the bearing should be replaced. If a new clutch has been installed, it is wise to replace the release bearing as a matter of course. The release bearing, pivot, and release cylinder pushrod contact faces on the Clutch Fork should be inspected for wear. The Fork should be replaced if excessive wear is evident. The Clutch Fork retaining spring clip should be checked and replaced if necessary. It is advisable to replace the clip as a matter of course. Installation involves cleaning the release bearing contact surfaces on the Clutch Fork and guide sleeve. No grease or lubricant should be applied to the sliding surfaces of the bearing or guide sleeve. The Clutch Fork/bearing assembly is slid into position over the guide sleeve, then the end of the Fork is pushed over the pivot, ensuring that the retaining spring clip engages correctly over the end of the Clutch Fork. The Fork should engage correctly with the retaining clip. Finally, the transmission is installed.

Inspect the clutch disc for wear, cracks, loose rivets, contamination or excessive runout (warping). Replace if necessary. Measure the depth of the clutch lining at lining rivets, if the shallowest rivet depth is less than 1 mm (0.04 in), replace the clutch disk. Inspect the flywheel for scoring, hotspots, cracks or loose or worn guide pins. Replace the flywheel if any faults are found. If the flywheel is removed from the engine, install using new bolts. Check to make sure the transmission pilot bearing rotates smoothly without play. Replace if faulty. Inspect and clean the release bearing module. Check the release bearing ball stud and spring retainer. Replace if damaged or worn. Clean the release bearing guide sleeve. Do not grease the release bearing module or guide sleeve. If the guide sleeve is greased, the release bearing may stick to it.

During installation, the release bearing contact surfaces on the release lever and guide sleeve should be cleaned. No grease or lubricant should be applied to the sliding surfaces of the bearing or guide sleeve.

The release bearing can be inspected by spinning it and checking for excessive roughness. Additionally, holding the outer race, an attempt can be made to move it laterally against the inner race to check for any excessive movement or roughness.

The first step in the removal process is the removal of the transmission.
