6. REPLACING PARTS

6-3. Rotary hook RP

If replacing the standard rotary hook with a rotary hook RP (lubrication-free rotary hook) on sub-class -40[] or -43[] machines,

use the following parts.

S52936-001 (ROTARY HOOK, W/BOX)

S35786-001 (SCREW, CAP W/HOLE M5-0.8)

Note: When using the rotary hook RP (lubrication-free rotary hook), set the sewing speed to 4,000 rpm or less.

1. Remove the needle and the presser foot.

2. Remove the needle plate (1) and the feed dog (2).

3. Remove the rotary hook.

4. Replace the screw (3).

Tighten the screw (3) securely.

5. Install the rotary hook RP(4) and the needle.

After installing the rotary hook RP, adjust the needle and

rotary hook timing. (Refer to page 28.)

6. Install the feed dog (2).

7. Install the needle plate (1).

Adjust the installation position of the feed dog (2) so that it

is in the middle of the needle plate (1) groove.

8. Install the presser foot.

Tighten the adjusting screw (5) as far as it will go, and then

turn it back the other way about three full turns.

(At this time, the head (A) of the adjusting screw (5) should

be almost flush with the edge (B) of the bed.)

NOTE: If the sewing machine is used while the adjusting

screw (5) is in the fully-tightened position, it will

cause oil to leak out through the gap between the

rotary hook shaft (6)and the bracket (7).
