The washer (10) stops the relief valve assembly (6-8) from being pushed out (6 is above your thumb nail). I think you are supposed to reuse the screw and washer (9 and 10) on the new pump.
You have a nice and tidy shop to work in.a new cooler is in place. our officials require a protective frame for technical inspection. I slightly modified the original semi-cabin that came with the tractor. next Thursday I'm going for a technical inspection, then the tractor will get new rubber and I'll run the engine after the renovation View attachment 75981
Histoparts in the Netherlands seems to have it. I linked to it in the previous post. That is the cheapest I have found. They want €16.50 for shipping to Czech Republic, but perhaps you find more items that can travel along.A conversion to a spin on filter is planned, but I can't get this conversion in Europe. in the meantime, I put an analog meter instead of a pressure sensor. lubricates to 5 bars at idle. The brand of tractor, however, has to undergo a technical inspection once every 4 years, otherwise it must not be on the road
