Note: Although any cuff can be removed immediately after removing the corresponding pulley (see paragraph 11), however, this method of removing the cuffs is not recommended. This is explained by the fact that the cuffs are very soft and it is very difficult to remove them without risking damage to the cuff housings, and also by the fact that it is difficult to restore the valve timing and belt tension after changing the position of the valve timing components. Therefore, it is recommended to fully perform the procedure described below.
1. Loosen the belt tension (paragraph 10 p. 1-14).
Note: If the belt is found to be contaminated with oil, remove it completely and then replace the seals (see below). Wash the surface of the engine and related components in the belt area to remove traces of oil. Install a new belt when reassembling.
2. If the belt is clean, pull it off the toothed pulley. Try not to bend it too much, working only with your fingers. Do not turn the crankshaft until the belt is installed. Cover the belt and secure it so that it is away from the work area and so that it does not slip off the other toothed pulleys.
3. Unscrew the pulley bolt and remove the pulley (paragraph 11).
4. Remove the right camshaft bearing cap bolts and pull out the defective seal. Clean the seal housing and polish off any burrs or sharp edges that could damage the new seal.
5. To install the new seal, a tool (Ford 21-009 B) and a bolt (M10, 70 mm long) with a washer are recommended. The tool will be required to install the seal in place when the camshaft bearing cap is secured with bolts. The same can be done using a suitable bushing (see Fig. 12.5). Lubricate the edges of the seal to facilitate its installation and press the seal into place flush with the outer edge of the bearing cap/housing. Install the bearing cap on the sealant and tighten its bolts in accordance with the instructions in paragraph 13.
6. However, it is possible to install the seal in a simpler way. Lubricate its edges and pull the seal onto the camshaft so that it is flush with the outer edge of the housing. Install the bearing cap on the sealant and tighten its bolts in accordance with the instructions in paragraph 13 (see Fig. 12.6). The seal should fit the housing without distortion, and when tightening the cap, it should not deform.
7. Install the pulley onto the camshaft and lightly tighten the mounting bolt. Then place the timing belt (clauses 18 and 21 paragraph 10) and tighten the bolt securely. Perform the remaining installation operations, including aligning the camshaft (valve timing mechanism) and restoring the belt tension, as specified in paragraphs 22-27 of section 10.
