Dismantling housing
– Remove the housing with pistons and springs.

– Lay new oil seals in water for some time before
mounting.
– Using the mounting mandrel (special tool),
mount the oil seal in the piston housing without
grease or oil.
– Pay attention to the mounting position of the
seal: the sealing lip must point to the mounting
mandrel.
– Oil the piston and assemble with springs.
Grease the O-ring with silicone grease.
– Mount the piston housing with mounting bolts
in the reverse order, paying attention to the
torque (see technical data).
– Add new oil (see technical data).
Defective oil seal on piston
– Drain the oil into a suitable container.
– Remove the cylinder head.
– Replace both housing bolts with 2 mounting
bolts (special tools).
– Using the mounting bolts, loosen the housing
maintaining an even spring pressure against
the pistons, making sure that the housing is
not canted.
