 Click image to enlarge Here's a picture of my oil cooler casing. The red arrow points to ERR7098 oil cooler o-ring, but that's not what I need. I need the 2 dowty washers for the banjos and 2 o-rings for the heat exchanger. Thanks! |

I think I've possibly found some part numbers, but they only correspond to a seller in Australia.
BS120 .....which appears to be the Viton o-ring BD233 .....which appears to be a dowty washer Still looking for an easier way to source these, and perhaps an actual LR part number. Click image to enlarge Click image to enlarge |

OK I found what I was looking for.
The heat exchanger inside the oil cooling casing of a TD5 uses two gaskets, (BS120) 2.62mm x 25.07mm Viton / FKM o-rings. The banjo bolt washers are M22 dowty seals. Both available on the internet from various fitting/gasket/hose stores. Click image to enlarge Click image to enlarge |

Mike, the 2 green rubber o-rings go into the area circled in green. First you need to remove the 2 squished old o-rings, probably black in color.
The 2 black rings you have, do they have a metal outer with rubber inner? If so, those are the dowty washers. They go over the banjo bolts circled in red. There's 1 remaining o-ring circled in blue, err7098. Click image to enlarge |
