S&S, 65-69 crankcase set, standard interior diameter. Natural for Harley Davidson

To use with a primary aluminum housing. 
S&S Superstock ™ charters, manufactured with 356-T6 aluminum, are much more resistant than OEM charters. 
OEM charters can be broken into high performance or even standard applications, as many of us discover for the bad ones. 
These S&S Superstock ™ charters can be used for both standard and racing applications. 
The important thing for the engines is the substantial savings in labor when using S&S charters. 
These charters are "configured" with main bearing slopes of the axis of the tooth wheel and bearing of lifts installed and main bearings of the axis of the piñón pressed and polished. 
The additional pieces that are supplied include timken wheel axis, cylinder asparagus, nickel -noskeus chatter bolts, crankcase accessories, oil pressure sensor, drainage plugs of the magnetic crankcase and synchronization and a folding screw Special S&S design alternator stator plug. The steering wheel scratches are mechanized to match the original 8-1/2 "diameter flyers. S&S boxes maximize the efficiency of crankcase oil by using a" with port "design ventilation duct. S&S boxes have a free space of up to 5 ", even, so no additional free space for race cylinders will not be necessary. S&S boxes are delivered completely with assembly instructions. Note: The S&S 36-69 oil pump (MCS 519922) can be used with all S&S 36-69. Note: In each and every one of the applications, the technician must evaluate the suitability of the components in combination with the other engine components, before the installation. 
It is important that an expert mechanic install and make the necessary adjustments.
