This inner primary is new never installed, but it sat in a barn for 10 years. The original owner said he used a belt primary instead. This is designed for the 1989 thru 1993 Harley Softail set-up which is also very popular for custom bikes. A stock Harley inner primary weighs about 9 pounds and this one is 12. That lets you know how tuff it is. All STD cases are precision cast from aerospace quality 355 T6 “A” Prime alloy with a tensile strength of 45,880 psi, the highest rating of any aftermarket cases. The bearing and seal should be removed and replaced, everything else just needs a good cleaning. These high performance inner primaries are no longer available from STD or Delkron.
This precision machined billet cover is made of 6061-T651 aluminum and is designed to reduce the amount of flex force, as seen in most end covers when using either a stock or high pressure clutch spring. This cover is “used” mainly because it came pre-installed on a 5 speed transmission. It was removed to install a hydraulic clutch cover. The cover was polished from the factory but has been scotch-brite-d for a satin finish. Cover only. Fits 5 speeds from 1987 thru 2006 and aftermarket 5 speeds.
