That is a problem I have never had unless the seal was bone dry, in which case it will quickly self-destruct anyway. Wet seals that are properly sized don't get hot. Nor do they wear out for the equ of 200k miles. If that is a problem, then the Christian Science oiling method isn't working, and I'd rig it like Andy has pix of at a link in a recent previous msg. The drilled holes I would aim to enter behind the bearing but inside the seal, so both the seal stays wet, and the bearings get slowly flushed. > On Sat, Nov 29, 2014 at 5:17 AM, Gene Heskett <[email protected]> wrote: > > On Saturday 29 November 2014 03:15:46 Marius Liebenberg did opine > > > > And Gene did reply: > > > On 2014-11-29 05:50, Gene Heskett wrote: > > > > On Friday 28 November 2014 16:31:58 Marius Liebenberg did opine > > > > > > > > And Gene did reply: > > > >> On 2014-11-28 18:27, Andy Pugh wrote: > > > >>>> On 28 Nov 2014, at 16:09, Kirk Wallace > > > >>>> <[email protected]> wrote: > > > >>>> > > > >>>> Sounds like a faulty design to me. > > > >>> > > > >>> Without a doubt, which is why the bearings failed. > > > >> > > > >> And the fact that there was absolutely no form of lubrication on > > > >> them to start with and the hardening of the bearings are very > > > >> suspect.
