question Zetor 6911 hydraulic pump

[Farmergiles]

Evening all, after removing the pump and it's mounting plate to clean the filter and renew O rings. Should this alloy washer be in this hole where the O ring and tube go ? I cannot see it in the parts book and don't know why it should be there.
Thanks.

Simplpy: no, if the tube is the right one.
That tube its gives in two or three lengths.

Joachim, thanks for the reply, tube looks ok, so i'll leave the washer out.

As a tip - use the original Zetor o-rings (the brown ones) - they works best over a long time. Its silicon material and not NBR as former mounted from Zetor.
