+ | ====== Primary Cover Differences ====== | ||
+ | |||
+ | The 1986-1990 cover uses a round, screw-in, primary chain inspection cover with a 'chevy symbol' indentation to unscrew it.\\ | ||
+ | It also used a relatively small, round, screw-in clutch adjustment cover, which also used the 'chevy symbol' tool. | ||
+ | |||
+ | On the 1991-1993 cover, the primary chain inspection cover is also round, but is mounted with two screws.\\ | ||
+ | Likewise, the small clutch adjustment cover is round and mounted by two screws. | ||
+ | |||
+ | On the 1994-2003 cover, the primary chain inspection cover is still round using two screws to mount it.\\ | ||
+ | But, the clutch adjustment cover is the large Derby Cover (4-bolt) that allowed the Ball&Ramp assembly to be removed without removing the cover. | ||
+ | |||
+ | With the Rubbermount models, starting in 2004-later, the cover has a rectangular primary chain inspection cover, held in place by two screws.\\ | ||
+ | The clutch adjustment cover is the large Derby Cover, but it is mounted with 6 bolts.\\ | ||
+ | (The 2004-05 polished covers have the same part number, 25430-04, but the 2006-later engines use part number 25430-06.) | ||
+ | |||
+ | Over the years, the primary cover has been available in different finishes (polished Aluminum, rough Aluminum, Chrome, Black, etc.) with different part numbers for those variations. | ||
