Hi All,
Trunnions on my spit have had the unfortunate DPO treatment with grease rather
than oil...
Tried using a grease gun to force oil in to displace the grease, no luck..
So I guess is dismantling time...
Is it worth cleaing the trunnions and reusing?
or should I just fit new ones?
If I fit new ones, should I go for original satnpart ones if I can?
Cheers
Tim
