There's no sleeve, just the aluminum housings the pins are pressed into.
Will look into Tap.
Thanks

So, the Bomar hatch to the mid cabin on Cruis'n Rulz! has been getting
progressively more creaky and sticky through the hinges. I squirted some
penetrating oil on them, and they totally locked up, to the point where
trying to move the hatch just started warping the frame. After having to
use an impact driver to loosen the 5200 bedded SS machine screws holding
the hinges to the frame (bitch...), I removed the hatch for closer eval.
Turns out the hinge pins are Polyethylene (cutting board material) rods.
The penetrating oil swelled them. I could not press them out,and
actually distorted one of the aluminum hinge housings trying, so ended
up drilling them out with a bit slightly smaller than the hinge bores
(bitch...).
If your Bomar hatches are sticky and creaky, look at the hinges. The
polyethylene pins appear as milky white nylon in the pin bores. DO NOT
try to lube them. I think the pins swell anyway over time, causing the
sticking, but there is no way to lube them without incurring the problem
noted above. Note: My Bomar hatches are circa 1990. I plan to make some
new pins, not sure what with yet.
FYI

You might consider checking with Tap Plastics. They have a store on
the same block at Gillian's Pool Hall at the south end of Lake Union,
and one just off Highway 520 on the East Side. Using a metal pin will
likely wear away the plastic sleeve, particularly if you open this
hatch a lot. Tap will have a variety of materials available and will
fabricate to suit. I'm sure they can recommend the right sort of
plastic for the task.
