Re: Bottom Trunnions
I am lubricating them with 140 grade oil instead of grease.

Re: Bottom Trunnions
Whilst I would be happy with using 140 oil - the trouble with using oil is that the seals are dust seals and not oil seals. They are not designed to keep oil within the trunnion.

Re: Bottom Trunnions
That is true but I believe the ‘creep’ of 140 oil provides better lubrication and it is no trouble to inspect the trunnions to check for leakage.philthehill wrote: ↑Sat May 28, 2022 7:44 am Whilst I would be happy with using 140 oil - the trouble with using oil is that the seals are dust seals and not oil seals.

Re: Bottom Trunnions
It is quite likely that grease contains 140 oil - in its soap carrier. The engineers specified grease for a good reason, I expect.
