Matthew been busy doing some o-ring research. The material for
the o rings is Buna n 70 ( Shawn = Not resistant to gasoline
Buna n 70) . This will come in handy. Thanks for making video.

as a bonus, I measured the 372xp o ring that goes on the PTO
bushing. its about .025" x .590" ID ... somewhere in there. I
can't seem to find an o ring that is that thin stocked anywhere
... anyone more info in this direction?
as a question, the material I ordered was BUNA N ... nitrile
o rings. if this is wrong material for these o rings let me
know. I can't imagine it is anything else, but if someone has
more info here that'd be great.

the 288 and 262 o rings do not appear to be available, the
288 due to ID, and the 262 due to o ring thickness of 1.78 not
available in viton

394 395 288 272 etc use an "xring" on the oiler to seal the
oiler output to chassis oil inlet.

Jacks has it at about 5 bux a shot. They really are pennies a
piece.
288 has an o ring that seals the oiler to the crankcase at the
outer race of the bearing. Same with 272.... again...o rings are
saw specific and usually husky charges 4 or 5 bux a shot when
they are only pennies each from a supply house.
Annoyingly....these o rings are required to be changed when
doing a rebuild yet they are not included in gasket / seal kits.

Shawn Nolder Buna-N 70. Not resistant to gasoline, but may work
outside the engine. Look into Viton for gasoline resistance.
