Anyone know what size the copper washers on the banjo fittings for the oil pipe at the pump and the transmission figured I’d have them on hand before I try and fit the new line

Ummm wait a min, are you trying to install the pipe that's in the above picture?

That's a pipe for an HST model, I don't think it's the same length as the gear drive?

It does take the same copper washers.

when I bought it I did specify a gear tractor and it appears to be the correct one it appears the right length and if I lay it up along side it appears to be the same. I won’t know exactly until I get the original off but either way I want the washers first. Worst case scenario I’d have to go with compression fittings.

Me too I’m trying to graft a 2030 front blade on it. And I’d rather tap the hydraulics there than under the seat

On another note I was wondering what this orange bolt head is? It wasn’t very tight and it appears to be some type of pin I looked in the WSM and didn’t see it, I was looking for a spot to use as a secondary return port for the underseat port IMG_1125.jpeg

Is that street elbow near the top of your picture a plumbing fitting?
If it is it isn't something to use for hydraulic pressures that are at least 10 times its rating.

It’s stopping a drip at the moment until the correct one gets here.
