INSTRUCTIONS FOR INSTALLING PRIMARY DRIVE CHAIN ADJUSTER KIT, NO. 1540026

  1. Remove the primary drive case cover, clutch, chain, motor sprocket, clutch sprocket and primary drive case.
  2. Lay the primary drive case face down and locate the position of the two 11/33″ holes.
  3. Drill the two 11/32″ holes and be sure to remove burrs.
  4. Locate the hole for the adjusting spring screw. Drill hole with a #25 drill, spot face and tap for 10-24 chain adjuster spring screw.
  5. Wash the chips from the case and assemble new parts as shown in drawing.
  6. After the chain adjuster parts and primary drive are assembled, check the chain adjuster shoe to make sure the tracks line up with the space between the chain side links.
    NOTE: The length of the chain adjuster screw is 2″. Do not use a longer screw because when adjusted up farther than the limit of a standard 2: screw, it will push the chain against the foot spud stud boss on the primary case and wear it through.
  7. Assemble primary drive case cover and adjust the chain so there is 3/8″ free up-and-down movement when checked through the oil filler cup hole.
  8. Fill to oil level with proper grade of oil.

PRIMARY DRIVE CHAIN ADJUSTMENT:

A new primary drive chain should be checked for proper adjustment after 300 miles of operation and each time oil is added thereafter.

Adjust so there is 3/8″ free up-and- down movement in the chain when checked through the oil filler cap hole.

PRIMARY DRIVE CHAIN LUBRICATION:

The oil level in the primary drive case should be checked every 500 miles and oil added, if required, and changed after every 2000 miles of operation. Use S.A.E. #10 Indian Oil.

NOTE: · Presence of red oxide on the chains indicates lack of lubrication so be sure to keep the oil at the proper level. Requests for adjustment will be refused on chains that, upon inspection, show that they have not received proper
lubrication.
