O-ring 2403/0244 JCB, genuine

O-ring 2403/0244 is a genuine JCB part for the JCB machines.

When hunting a leak, check the joint's O-rings first, since many oil leaks come not from expensive parts but from these small rings failing. Whenever a joint is taken apart, renew its ring, as the old one has taken a permanent set and will not seal again.

Fitting

On assembly, clean the groove and mating face, wet the ring with the working fluid or suitable grease and seat it without twisting. Protect the ring as it passes sharp edges and threads, tighten the joint to the specified torque and check for leaks under pressure. Spare rings are stored somewhere cool and dark, away from sunlight and ozone, since rubber left in the light cracks at the surface and starts leaking soon after fitting. Before fitting, inspect the ring for cracks, cuts and moulding flash.
