Bearing noise heard on left front wheel of 997 during 200 hour maintenance by spinning it by hand
and comparing it to the right wheel.
Spun as free as the right wheel, no hang ups, but was noisy.
Pulled the castor down, (an el cheapo 12 ton press does a great job doing this).
Found that one bearing was noisy and one was OK.
The noisy one was curded up with dried grease, the good one still had good grease on it,
but not very much.
Cleaned both with kerosene and repacked with JD *blue* lithium base high moisture environment grease.
Checked both bearings for any hang ups or glitches while rolling in my hands, seemed to be
Coated all internal bushings, spacers and axle shaft with Anti-Seize, these parts really
need the anti-seize because they can rust and lock up on the bolt axle.
Reassembled and checked out, no bearing noise, feels good spinning.
Suspect the bearings weren't properly packed with enough grease to start with from the looks of the better
No way should this have happened with just 202 hours had the caster been properly assembled and greased
from the get-go.
Will pull down the right wheel to check, even though it sounds good spinning, suspect not enough grease
on them either.
Might be a good idea to jack up the front end and check the spinning and sound once or twice a year, imho.
