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. |
