Another piece (or two!) of advice, print out the HOW TO for whichever block you have, and keep it right there where you're working so you can refer to it.
Early block:
I am rebuilding an old style touch control block Casting number
351686R1 (The early Touch Control part numbers are 351981R1, and 354383R1 through 354383R4. Credit
@Glen) on a 1948 Cub. The old style has some significant differences from the new style. I have searched this sight as best I could for a step by step repair complete with pics.like troop has done for the new style but cannot seem to find anything. Can anyone point me in the right direction? Otherwise I will document my rebuild and post it as I go.
Thanks,
Joey J.
Later block:
This is a rebuild for hydraulic block 360719R1. Different block(s) will require different parts so make sure to get the right rebuild kit. There are some variances as well but this should still be of assistance. The pictures should tell the story on their own. As has been previously noted on the forum, the replacement filter (screen) is a bit too long. You will have to make it fit as best as you can (it is about an 1/8 inch too long).

If you don't already have one of these (NOT the one in your kitchen!!),
...grab one from Walmart! Keep those parts from each bore in line with the same orientation as the photos in the HOW TO.
