Refitting the left-hand cover

– Clean the housing and cover gasket faces. Smear the casing's parting surface with Loctite(510). – Replace all removed O-rings. – Coat the flat gasket surface (H) on the intake manifold (I) with silicone (resistance to hydrocarbons). Slide the gasket onto the studs (G) with the adhesive face on the cover side. – Screw two diametrically opposed locating studs (F) into the intermediate housing to refit the cover. – Check that the two centring pins (K) are present. – Remove the locating studs (F). – Fit screws (C) and (E) uniformly and alternately to a torque of 9 to 12 daN·m.

Note: If resistance is felt on tightening, separate the cover from the housing and check the positioning of tube (I) with the pump. Also turn the pump driving pinion.

– Fit nuts (D) coated with Loctite (242) and tighten to a torque of 1,5 to 2 daN·m. – Screw the bowl (B) manually with moderate force. – Check the seal on the cover and bowl gasket surface.
