Spherical seat

My old sloppy spherical seat is heavily greased.
Shall I grease the new one or not?
The WSM says nothing about it but Haynes says no lubrication.
That is correct?
It's a 2200 TC 1976.

Hi Per,

The spherical seat is made from a synthetic polymer that does not require lubrication, however gven its location, a covering of grease flung from the sliding joint and the front universal (especially if fitted with a grease nipple) is highly likely. From my own experience, the OEM creamy coloured seats have a particularly short lifespan, which is probably a result of degradation resulting from exposure to grease.
