Replacing the primary shaft seal of the JC5 gearbox (Renault Espace III)

• The JC5 gearbox primary shaft seal is supplied as spare parts mounted on the clutch release bearing guide sleeve. When replacing the seal, there is no need to separate the gearbox housing from the clutch housing.
• To replace the seal, you must use the following special tools:

- elastic pin puller Emb. 880;

- device for installing the guide sleeve of the clutch release bearing Emb. 1163.

• Remove the bearing and the clutch release fork.
• Remove the two bolts securing the clutch release bearing extension sleeve (Fig. 6.30).

• Install the Emb. 1163 tool onto the guide bushing and tighten it.

• Screw the Emb. 880 puller into the cup of the device and remove the clutch release bearing guide sleeve (Fig. 6.31).

• Using two screwdrivers, remove the spruce from the clutch housing, being careful not to damage the surface of the housing hole.

Installation

• Install the clutch release bearing guide sleeve and seal with protective cap into the Emb. 1163 tool.
• Make sure the guide bushing plate is positioned on the fixture without being tilted and tighten it slightly.
• Install two studs Emb. 1163 in place of the two clutch release bearing guide sleeve mounting bolts.
• Lubricate the outer part of the seal and the seat on the input shaft with transmission oil.
• To prevent damage to the working edges of the seal, wrap the splines of the gearbox input shaft with adhesive tape.
• Install the seal in place, ensuring that the tool is positioned perpendicular to the crankcase surface.
• Remove the protective cap and the device.
• Make sure that the guide sleeve plate is correctly positioned in relation to the crankcase and that the guide sleeve does not contact the input shaft.
• Install the two guide bush mounting bolts and tighten them to 24 Nm

Note: The supplied guide bushing has the seal moved forward to allow for subsequent installation into place on the input shaft.
