Cuffs — replacement (Peugeot Partner I)

Crankshaft

Right cuff

1. Remove the timing belt crankshaft sprocket as described in paragraph 8.

2. Mark the cuff installation depth.

3. Using a hook-shaped tool, pull the cuff out of the housing. Alternatively, drill a small hole in the cuff and pull it out using a self-tapping screw and pliers (figure 16.3).



4. Clean the crankcase seal housing and the crankshaft sealing surface.

5. Dip the new seal in clean engine oil and insert it into the housing (open edge outward) to the depth noted during removal, using a suitable piece of pipe with machined ends or a socket head. A piece of thin plastic or tape wrapped around the front end of the crankshaft will help prevent damage to the seal when installing it.

6. Remove plastic or tape from the end of the crankshaft, if applicable.

7. Install the timing pulley on the crankshaft as described in paragraph 8.

Left cuff

8. Remove the flywheel as described in paragraph 18.

9. Follow the steps described in paragraph. item 2-6. Please note that when installing, the outer sealing edge of the cuff must be facing outward; if it is facing inwards, use a piece of bent wire to pull it outwards. Be careful not to damage the cuff.



10. Install the flywheel as described in paragraph 18.

Camshaft

Right cuff

11. Remove the camshaft timing pulley as described in paragraph 8. In principle, there is no need to completely remove the timing belt, but keep in mind that if the belt has become contaminated with oil, it should be replaced.

12. Using a hook-shaped tool, pull the cuff out of the housing (figure 16.12). Alternatively, drill a small hole in the cuff and pull it out using a self-tapping screw and pliers.



13. Clean the cuff housing and the sealing surface of the camshaft.

14. Dip the new seal in clean engine oil and carefully place it on the end of the camshaft, with the open edge facing out. A piece of thin plastic or tape wrapped around the front end of the camshaft will help prevent damage to the seal when installing it.

15. Insert the cuff into the housing until it is flush with the end surface of the cylinder head. To press the cuff into place, use an M10 bolt (screwed into the end of the camshaft), washers and a suitable piece of pipe with machined ends or a socket head.



16. Install the timing pulley on the camshaft as described in paragraph 7.

17. If applicable, install a new timing belt as described in paragraph 7.

Left sealing ring

18. The cuff on the left end of the camshaft is missing. Sealing is provided by an O-ring installed on the vacuum pump flange. The sealing ring can be replaced after unscrewing the bolts and removing the pump from the cylinder head (see chapter 9). Note the smaller o-ring that seals the oil supply gallery to the pump. Deterioration and loss of this oil can lead to leakage through the mating surfaces of the pump/cylinder head (figure 16.18).
