Dismantling and Reassembling the chain tensioner.

IMPORTANT - Ensure, when reassembling the various component parts :

• that they slide freely in their locations,
• that the oil holes are all clean.

SEDIS type tensioner, fig. I :

• Set the ratchet as shown in detail (1) and take out the pad, the rack and the spring, in one movement.

Warning : do not remove the ratchet (a) from its location (its return system would prevent it being refitted).

• Reassemble by carrying out the removing operations in reverse.
• Lock the tensioner by moving the ratchet as shown in detail (2).

RENOLD type tensioner, fig. II :

• Lock the tensioner using a 3 mm Allen key.
• Fit the pad to the tensioner body.
• Place, fig. III, a length of steel wire 2 mm in diameter, between the tensioner body and the pad to prevent it being reset by accident.

New tensioners are supplied fitted with a plastic tab for this purpose.

Place the GAUZE FILTER in position, fig. IV.

Fit the tensioner.

Tighten the bolts, fig. V to a torque of 0.6 m.daN (6 Nm, 4,5 lbf ft).

Setting the tensioner.

SEDIS type tensioner, fig. V.

Set the tentioner by turning the ratchet to the right.

RENOLD type tensioner, fig. VI :

• Remove the length of wire or the plastic tab (new tensioner) and push in the pad until it makes contact with the bottom of the bore in the tensioner body.
• Release the pad.

IMPORTANT - On neither of these types of tensioner should the movement of the pad be assisted.
