S&S, 84-91 Coter set, interior diameter of 3-5/8 ". Natural for Harley Davidson

S&S Superstock ™ charters, manufactured with 356-T6 aluminum, are much more resistant than OEM charters. 
OEM charters can/can be broken into high performance or even standard applications, as more than a few of us discovered by the bad ones. 
These S&S Superstock ™ charters can be used for both standard and competition spare applications. 
It is important for the motors manufacturer the substantial savings in labor that involves using S&S charters. 
These charters are "configured" with main bearing slopes of the dentated wheel axis and installed lifs bearing and main bearing track of the piñón axis pressed and rectified. 
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 scrapers 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" ventilation duct. 
S&S boxes have a free space of up to 5 ", even, an additional free space for stepped cylinders will not be necessary. 
S&S boxes are delivered completely with assembly instructions. 
Note: For Evo Big Twin 84-E85 models, you must use an L85-91 style clutch bolt kit. 
These can be requested separately as MCS 505266 (Gardner-Westcott) or 989599 (Colony) only in standard lengths. 
Note: The aluminum H-D oil pump (26190-73) or the S&S oil pump, MCS 519923, can be used in 70-91 applications. 
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.
