1. See Chapter 1A, Sections 20, 22, 23, 24 and 30.
2. The camshaft drive belt must be replaced in any case, unless it is in excellent condition. Replace sprockets if they are damaged or defective.
3. Inspect the camshaft lobes and journals for wear and damage. If there are obvious defects, the camshaft may need to be replaced. Also inspect the bearing shells in the cylinder head and covers.
4. Clean the camshaft oil line with solvent and blow it out with compressed air. All openings in the main line must be cleared (see photo).
5. Inspect the tappets for wear and tear and replace them if necessary. When replacing the camshaft, the tappets must be replaced, and it is also advisable to replace the valve springs.
6. If the starter ring gear is damaged, it must be replaced (produced in a specialized workshop). Minor defects on the flywheel surface that contacts the clutch can be removed by regrinding (also produced by a specialist).
7. Inspect the manifolds as indicated in chapter 1A, Section 29, omitting all mention of connecting hoses.
8. Check the camshaft drive belt tensioner for free rotation of the tension pulley bearing and wear or deformation of the spring. If necessary, replace defective parts - the tension pulley, bearing and support shield are replaced only as an assembly (see photo).
Crankshaft centering sleeve
9. On the latest models with an XU engine, there is no centering sleeve at the end of the crankshaft, and the diameter of the gearbox input shaft is correspondingly increased.
10. When using a new model crankshaft with an old type drive shaft, it is necessary to install the centering sleeve yourself.
11. In the opposite situation (new drive shaft and old type crankshaft) it is necessary to remove the centering sleeve.
Oil pump - disassembly, inspection and assembly
12. Remove the 6 bolts holding the two halves of the oil pump together. Disconnect the halves, being prepared for the fact that the spring and plunger of the safety valve may pop out (see photo).
13. Inspect the rotors and pump body for wear and damage. There is no data on the maximum permissible wear of pumps of this type, however, obvious wear of moving parts indicates the need to replace the pump, with the exception of the spring and plunger of the safety valve, if parts for the pump are not available for sale (see photos).
14. Before assembly, thoroughly lubricate all pump parts. Tighten the pump parts with bolts, being careful not to crush the membrane.
15. If you are going to replace the pump, it is advisable to replace the crankshaft sprocket.
