Plug seal replacement
Step 1
1. Remove old seal ring using a knife, screwdriver or similar.
Be careful not to damage the plug surface.
If using a screwdriver it must be placed underneath the plug
groove (see drawing 1).
2. Grease the new seal ring with Paralique GTE 703, which is
included in the service kit.
Only use a very small amount of grease.
3. Fit the seal ring on the plug without pressing it into the groove.
Be careful not to twist the seal ring.
Use a screwdriver (two turns) to fit the seal ring properly and to
ensure it is not twisted (see drawing 2).
4. The seal ring can now be mounted by hand or with the Alfa
Laval plug tool.
