Got the 226D out to mow today. Overall very happy with how the R4’s don’t tear up the grass like the R1’s did. Still debating getting rear wheel spacers since I can’t use the turn buckles to adjust the lower lift arms.

Made a little more progress today on the 226D ...I pulled the injectors and injection pump...and be sure to go over it thoroughly before I start to put it to work.

This is a helpful thread. Not sure if I should make a new post or ask here. (happy to delete and do that).
I am dealing with a fuel leak at the top of the injection pump on my 226D. I have replaced o-rings and crush washers on other injection pumps succesfully. I have never taken this one apart. Any concerns removing the injector line and opening the port up to measure o-ring and sealing washer to find a replacement? I have not been able to find replacement seals, so I guess I have to take it apart and measure what is there.
Any info for where to order the seals?
