DOWN TO 3/16" FROM TOP (MEASURE
WITH HORSESHOE GAUGE) NUT
IS ADDED TO BOTTOM (SNUG)

Notes: This is step 9 of the Pressure Adjusting Valve procedure on page 4. 7/16 x 2" bolt threaded into 3/4" x 1/8" solid bushing to a depth leaving 3/16" from top (checked with a horseshoe gauge), nut snugged on the bottom, then drilled and pinned. ("3/4 x 1/8" is presumably a pipe-thread reducing bushing designation, as written.)

Handwritten assembly procedure (block capitals, black/blue ink) on Winn Supply Co. / Kaman letterhead (same as page 3). Title: PRESS. ADJ. VALVE (pressure adjusting valve).

   RATTLES — BESURE WHEN 7/16"
   BOLT IS ALL THE WAY DOWN
   SPRING ISN'T COMPRESSED ENTIRELY

Notes / geometry: The pressure adjusting (relief/bypass) valve is a spring-loaded ball check built in a 1" x 3/4" x 3/4" pipe tee: a 3/4" x 8" nipple (filed flat on top, the seat) screwed into a 1" x 3/4" reducer bushing (shortened to 3 threads) in the tee; a 7/8" stainless-steel ball and spring sit in the tee; a 7/16" x 2" bolt (adjuster screw) threads through a drilled ("U" letter drill) and 7/16"-tapped 3/4" x 1/8" solid steel bushing to compress the spring. Step 9 is on page 3. Shop references: drill index, tool chest next to drill press, bin below tool chest.

Notes: leg braces need a 1/4" hole; one bottom hole drilled larger on the tank side; one left and one right brace. Agitator: "14" center" (hole pattern/centers 14" — exact meaning as written), four 7/16" outside holes and one 3/8" center hole; 1" Greenlee punch for bottom center hole.

Handwritten note (pencil, cursive) on Winn Supply Co. / Kaman letterhead; circled "2" at top right (continuation of page 5). Includes a small sketch.

Sketch: a rectangular grid/screen drawn as a row of 11 vertical bars (labeled "11" below) crossed by 2 horizontal bars (labeled "2" at left), with "prongs" (label at upper left, arrow pointing to the protruding top ends of the vertical bars). Arrows from the lower-left point to the bottom edge, tied to the note "Grind edges to remove sharp corners". No dimensions given. Interpreted as a cut piece of grating/expanded screen 11 openings by 2 openings, with prongs left protruding.
Agitator wiper attaches to shaft with 10-24 screw (alternative 8-32).

Agitator bearing: Fafnir RCJC 1" (flange-mount ball bearing unit, 1" bore) — "NO SUBSTITUTE". Bearing must have grease fittings; loosen Allen set screws [last word partly uncertain: "setting[s?]"].

Sketch 1: two horizontal shafts drawn one above the other. Upper labeled "old shaft", lower "new shaft"; dimension arrow over the upper shaft "12"" (shaft length 12"). Both have a keyway slot drawn at the right end. A vertical member labeled "bearing →" crosses near the right end; a vertical tick on the new shaft labeled "mark" — i.e., the bearing position/keyway is transferred from the old shaft to the new.
Sketch 2: a single shaft with dimension arrow "10" (10", unit not written) running to a vertical plate/bearing at the right; a small circle near the right end labeled "Allen set screw", with an arrow labeled "counter sink" pointing to the set-screw location (countersink/spot in shaft for the set screw).

Notes: shafts are 1" diameter; one shaft 12" long (keyway end at pulley side), another 10" with a countersink for an Allen set screw.

Notes: agitator bearing bolts to tank with 7/16 x 1-1/4 bolts; 7/16 copper sealing washers inside tank; snug then 1/2 turn. Agitator has a center blade positioned over the tank outlet hole, and outside blades bent at the leading edge (left down, right up) — i.e., pitched paddles.

Sketch: a vertical line at left labeled "tank" (tank wall). A horizontal shaft enters from the wall into a rectangular hub/collar labeled "Agitator" with a dot (the cross pin / pin hole) in it. Above, a T-shaped member (a blade or bracket on a stem) is drawn over the hub. Dimension arrows below give the distance from the tank wall to the pin hole as "≈ 1"" (approximately 1").

Notes: agitator connecting pin: 1/8" pilot hole, 1/4" final hole, roughly 1" in from the tank wall; two 1/4 x 1-3/4 (or 1/4 x 2") bolts attach agitator to shaft.

 1/4 x 1 1/2  Rivets

[sketch 2]

Sketch 1: profile of the tank's top edge — a vertical wall with an outward-turned rim; arrow "Lip" points to the rolled/flanged lip, arrow "hole" points to a horizontal drilled hole through the lip region (dashed lines showing hole through lip).
Sketch 2: section of the rivet joint: a rivet passes through the tank lip and a "Leg Brace" (arrow to a bent bar on the inside face, shown jogged/offset). Labels: "inside" (arrow pointing to the rivet head side, round head inside), "outside" (arrow to the outer face), and "MUSHROOM by hammering" (arrow to the rivet tail on the outside, peened over).

Notes: leg braces riveted to tank lip through 1/4" holes centered in the lip, using 1/4 x 1-1/2 (or 1/4 x 1-1/4) rivets, head inside, tail mushroomed outside by hammering. (Note: the arrows in sketch 2 put "inside" on the left/brace side and "outside" on the right; the leg brace is on the inside face of the wall.)

Notes: tank lid (hinged lid presumably) attached with pop rivets in 3/16" holes; wooden supports hold lid up during drilling; rivet tails hammered flat with a long bar; a drill guide is used for both sides of lid. The word after "Drill hole with" is unclear (looks like "rivet"/"rivit" — possibly "Drill hole with [lid] [nut?] only").

Notes: "Reducer" center hole tapped 3/16 x 24 (as written; a 3/16-24 thread is unusual — recorded verbatim). Second screen (distinct from the 11 x 2 agitator screen on page 6) is 9 x 9 holes, hammered flat-side-up into a template, trimmed with cutters, center hole punched.

Notes: tank bottom outlet: a 1-1/2" street elbow plus half of a 3-1/2" nipple (nipples cut in half with pipe cutter), sealed with Teflon, assembled to the reducer bushing and screwed into the bottom of the tank. ("1 1/2" in parentheses likely the street-L pipe size.)

Notes: the other half of the cut 3-1/2" nipple goes into a companion flange (which bolts to the pump inlet, page 17). A 1-1/2" three-ply hose connects the tank outlet nipple to the reducer bushing with two size "32H" hose clamps. (The note calls it "discharge hose", though from context it runs tank→pump.) Spacers go under the pump feet "wings" with flange facing inward; four 3/8 x 2" bolts (continued on page 17).

Notes: the pump is clocked so the line from tank to pump is straight; pump "caps" (clamps/end caps) are centered with equal gap each side and tightened evenly because over-tension can break the cap.

Notes: pump must be square to the motor (motor template is square) or belts wear badly. Pulley shaft uses 3–5 washers (shims) depending on tank. Jack shaft is countersunk for set screw the same way as the agitator bearing. The last line is partly torn/smudged: first fraction reads "1/32"" (could be "7/32"", cf. page 20), second fraction illegible-ish "[7/64?]"".

On Pulley Guard
Bottom center inside ("Bottom" underlined)

Top center up 8" ("Top" underlined)
down 4"
1 1/2" inside

Sketch: a teardrop/pear-shaped outline (the pulley-guard outline, narrow end up-right, rounded wide end at lower left), drawn freehand. Annotations on the sketch:

• At the top (narrow) end, a tick mark on the outline with an arrow pointing inward labelled "1 3/4"" (hole 1 3/4" in from the edge at the top/narrow end).
• Along the bottom curve, a curved arrow labelled "8"" running from a tick at the lower-left to a tick at the lower-right of the rounded end; at the lower-right tick an inward (upward) arrow labelled "1 1/2".
• On the left side, a curved arrow labelled "4"" running up from a tick at the lower-left to another tick on the left side; at that left tick an inward arrow labelled "1 1/2"".
• Beside the sketch: "Lay down with screen [on?] a table".

Interpretation (as written, not added): three hole marks — one at the narrow end 1 3/4" inside; one 8" along the edge from the bottom center, 1 1/2" inside; one 4" along the edge the other way, 1 1/2" inside. Page 34 then says drill (3) holes at the marks.

A bracket on the right side marks a band roughly in the upper-middle of the shank with diagonal hatch lines and the label "tape" (the region to wrap with Teflon tape). No dimensions shown.

Notes: In step 1, "TOP" was struck and "BOTTOM" written above it; in step 2, a struck word ("TOP"? / "BO") was replaced by "BOTTOM" written above; in step 3 a word before "TAP" is scribbled out [illegible]. "SS BALL" = stainless steel ball, 7/8". This page confirms the bushing on p. 40 is 3/4" x 1/8".
