PULLEY Assemble double-disc take-up onto shaft Collar side must face towards pulley Step 10

Step 10. Locate new double disc take up cam, and slide cam onto end of mainshaft with collar side toward the pulley end of the machine.

Step 11. Push mainshaft towards pulley end of machine until timing spot in the mainshaft aligns with spot screw in coupling. Tighten spot screw into spot of mainshaft and then tighten remaining 2 screws.

(3) screws PULLEY Push shaft towards pulley until time spot on shaft lines up with spot screw in coupling. Tighten spot screw, then tighten remaining (2) screws. Step 11

INSTALLATION PROCEDURE, continued

Note: For differential feed machines follow Steps 12A, 12B and 12C. For plain feed machines follow Step 13.

Step 12A. Align spot screw in feed lift eccentric with spot in mainshaft and tighten spot screw, then tighten remaining screw.

PULLEY Align eccentric so its time spot screw lines up with time spot on shaft. Tighten spot screw, then remaining screw. CAUTION: OVERTIGHTENING SCREWS MAY CAUSE BINDING Step 12A

Align eccentric so its time spot screw lines up with time spot on shaft. Tighten spot screw, then remaining screw. CAUTION: OVERTIGHTENING SCREWS MAY CAUSE BINDING Step 12B PULLEY

Step 12B. Align spot screw in feed drive eccentric with spot in mainshaft and tighten spot screw, then tighten remaining screw.

Step 12C. Locate top half of eccentric strap which was removed previously. Reassemble strap in same position as it was prior to removal, and tighten screws. After assembly turn machine over for several revolutions to make certain machine does not bind. If machine binds, check strap position and repeat step 15.

Reassemble top half of eccentric strap Tighten both screws CAUTION: OVERTIGHTENING SCREWS MAY CAUSE BINDING Step 12C

Step 13. Align spot screw in double feed eccentric assembly with spot in mainshaft and tighten spot screw, then tighten the remaining screw.

Step 14. Reassemble looper drive to end of mainshaft, replace washer and tighten in place with screw.

Step 15. A) Assemble new cast off plate and eyelet from kit and tighten with 2 screws. B) Center double disc take up so that cast-off plate is centered between the take up discs.

A. | Assemble new cast-off plate and eyelet from kit onto machine and tighten with (2) screws B.) Center double-disc take-up so that cast-off is centered between take-up discs Tighten screws on take-up Step 15

INSTALLATION PROCEDURE, continued

Step 16. A.) Assemble new front head cover and gasket to machine with its 2 screws. B) Attach connecting link to lever with its screw.

B.) Connect link to lever A.) Assemble cover with gasket to machine Step 16

Notch in needle thread take up positioned over needle thread eyelet Step 17A

Step 17A. With needle bar at top of stroke, position new needle thread take-up so that notch in take-up fits over needle thread eyelet.

Step 17B. Rotate take-up clockwise, lower it into position over control lever, and attach to cover with its two screws.

Close-up of a sewing machine needle and mechanical components, labeled 'Step 17B' (no readable text or symbols on the main subject)

New needle thread take-up is positioned vertically so bottom of take-up surface is even with cover screw Needle thread strike-off is set so it just touches needle threads at bottom of needle stroke Step 18

Step 18. Position new needle thread take-up vertically so bottom of take-up surface is even with top of cover screw. Thread machine so that one needle thread passes through each hole in needle lever thread eyelet.* Needle thread strike-off is set so it just touches needle threads at bottom of needle stroke.

*Same as standard threading.

INSTALLATION PROCEDURE, continued

Step 19A. Reassemble plastic oil reservoir with its screw.

Reassemble springs Reassemble covers Reassemble cover Step 19B

Step 19C. Remove Looper thread guide wire and slide spring from kit over the wire and then replace guide wire on machine.

Reassemble plastic oil reservoir Step 19A

Step 19B. Reassemble chamber cover, top cover, main frame end cover and presser foot tension springs.

cial Step 19C

PULLEY Both looper thread pull-off eyelets are set maximum to right One looper thread per eyelet Double-disc take-up should be set so that looper thread casts off high point of cam when needle tips (on downstroke) are between bottom of throat plate and top of loopers Step 20

Step 20 Set both looper thread pull-off eyelets maximum to the right. Set double disc take-up cam so that looper thread casts off from high point of cam when tips of the needles on down stroke are between bottom of throat plate and top of loopers. Thread one looper thread through each hole in new eyelet from kit.

Step 21 Set needle thread tensions to high, so that needle threads are pulled up very tight against material. Set looper thread tensions to low, so that maximum amount of looper thread is in the material.

Needle thread tension to be high, so that needle threads are pulled up very tight against material Looper thread tension to be minimal, so that maximum amount of looper thread is in material Step 21
