Locate the stamped letter “O” on the front of each front countershaft fourth (eighth) speed gear that aligns with the keyway. Paint the front of the corresponding gear tooth with white paint for greater visibility when timing the countershafts later. Do this for each of the three front countershafts. 512
Locate the three gear tooth spaces on the mainshaft fourth (eighth) speed gear, stamped with the letter “O”. Paint the front of each tooth space with white paint for greater visibility when timing the countershafts later. If there are no stamped letters, count the number of gear teeth (result should be divisible by three). Place a white paint mark on any tooth space. Then count around one-third of the total spaces and place the second white mark. Finally, count around one-third of the total spaces again and place the third white mark. The three marks should now be evenly spaced around the gear. 513
