6. The position of the wormgear must be adjusted so

the worm contacts the center of the wormgear teeth.

Failure to make this adjustment may cause reduced

efficiency and life as well as overheating and tooth

breakage.

7. Apply Prussian Blue lightly but evenly to both sides

of five adjacent teeth on the bronze wormgear.

8. Install the intermediate shaft assembly into the

gearcase so that the intermediate shaft pinion will be

on the same side as the output gear when the reducer

is reassembled. Install the open bearing housing and

secure with two bolts at diagonal corners. The hollow

dowel pins must be in place.

9. Rotate the input shaft so the "blued" wormgear teeth

are rotated through the gear mesh. Then rotate in the

opposite direction. Marks of contact will be made by

the worm in the bluing on the wormgear teeth.

10. Remove the open bearing housing and

intermediate shaft assembly. Examine the contact

pattern on the wormgear teeth. The ideal pattern is

centered in the wormgear teeth.

11. If the pattern is not centered, the intermediate shaft

must be moved in the direction where the contact

shows the heaviest. Remove a thin shim from the

bearing cup on the side that the contact is heaviest and

install it under the cup on the opposite side. Shims may

be moved from one side to the other but the total

number of shims must not be changed, as this controls

the endplay of the bearings.

12. Repeat the above steps, cleaning, rebluing and

inspecting each time, until the contact pattern is

centered on the wormgear.

13. Install the intermediate and output shaft

assemblies. Apply sealant to the gearcase machined

sealing surfaces. Install the open bearing housing and

tighten all bolts. Be sure all parts rotate freely.

14. Lubricate the shaft seal surface and seal bore

liberally with SHC 634. Install a new seal, taking care

not to cut or roll the lip or dislodge the seal garter

spring. Seat the seal flush with the outside of the

bearing housing. The use of a driver is recommended.

15. Fill unit with proper amount of lubricant. See

charts. Use sealant on plug threads. Test unit.
