Tom Bond said: (quoted from post at 20:59:05 01/15/13) Does anyone know if that "O" ring for the oil inlet line over the rocker arm assembly is just a normal "O"ring and not anything special? Nobody seems to list it anywhere that I can find. I have 100 different sizes at the shop in stock and if it's just plain old rubber, I'll match it up and go for it.

Part number on the new Holland web site is EAA6594A. A Google search shows it available lots of places for around a buck individually, as low as 35 cents a piece if you buy a bag of 10. No one seems to let on what size it is though, and from the pictures it looks like it's not really an o-ring. It's listed as a "seal" and it looks like a thick rubber washer, flat on the top and bottom, and straight up-and-down on the outer rim and inner race.

The "A" suffix usually indicates 70 durometer hardness and used when temperatures are a sustained 250-300F.
