b'Safety Steering ColumnsToll-free in USA: 1-888-STEER-USInternational: 1-307-472-0550E-mail: sales.woodwardsteering@gmail.comCAUTION: When calculating column length, bear in mind that this is a telescoping SAFETY column, which in order to be effective must be installed as close to fully extended as practical. A column that is too long and has to be installed in the car in a collapsed position obviously defeats the purpose. 3 .FromFigure2below,selectthesplinedtelescopingshaft(SL20,SL17orSL15)thatwillbestfityourinstallation.NotethattheSL20andSL17shaftsareintendedtopassthroughasupportbearingandconnecttoaU-jointoutsidethefirewall.InsomecasestheU-jointmaybeinsidethefirewall,withtheintermediateshaftpassingthroughthesupportbearingasintheillustrationatthebottomoffigure2.InthiscaseyouwouldselecttheSL15.4 .Subtractfromyouroverall distance theamountwhichcorrespondstoyourchosensplined shaft(14,11,or9.25inches).5 .Theonlyremainingpartisthejacket.Todetermineitslength,subtractanadditional1.0inchforthebootcuffand2.38forthequickreleasesteeringwheelhub.Theremainderisthelengthofyourcolumnjacket.Nowselecttheclosestjacketfromthelist.Ingeneralitisbettertoroundtheresultupwardforexample,foracalculatedlengthof21.50,usea22.75jacket.Inthiscase,tofitthecarthecolumnwillhavetobecompressed1.25inch,whichwillreduceitsavailablecollapsestrokebythesameamount.Formostapplications,upto2.0inchesisusuallyacceptable.Ifyoucannotgetitcloserthanthis,recalculateusingtheothersplinedshaft.Fig. 2firewall bearing (typical)mm=inchesx25.4inches=mm25.4 Overall distance (measure this first)subtract 14.0 to be determined(SL20 splined shaft) (Jacket)subtract 11.0 to be determined(SL17 splined shaft) (Jacket)subtract 9.25 to be determined(SL15 splined shaft) (Jacket)subtract 1.0 (all) subtract 2.38 (all)Standard SCA700 jackets are 13.75, 15.75, 17.75, 20.75, 22.75 and 24.75ThepartnumberforyourSCA700SafetySteeringColumniscomposedofitsjacketanditssplined lower shaftinthatorderforexampleSCA700-1575-SL15,SCA700-2475-SL20,SCA700-2075-SL17,etc.SCA700 Calculation Examples (inch):1. Calculated using SL17 splined lower shaft:Overall distance 37.5; Lower shaft chosen SL17; Jacket (calculated from fig. 2): 37.5 minus 11.0 minus 1.0 minus 2.38 = 23.12 Closest jacket from list is 24.75the part number for this column would be SCA700-2475-SL17 (install slightly compressed).2. Same as above, but recalculated using SL20 splined lower shaft:Overall distance 37.5; Lower shaft chosen SL20; Jacket (calculated from fig. 2): 37.5 minus 14.0 minus 1.0 minus 2.38 = 20.12 Closest jacket from list is 20.75the part number for this column would be SCA700-2075-SL20 (results in a closer fit than #1).3. Overall distance28.0; Lower shaft chosen SL15; Jacket (calculated from fig. 2): 28.0 minus 9.25 minus 1.0 minus 2.38 = 15.37Closest jacket from list is 15.75; the part number for this column would be SCA700-1575-SL154. Overall distance 32.0; Lower shaft chosen SL17; Jacket: 32.0 minus 11.0 minus 1.0 minus 2.38 = 17.62 Closest jacket from list is 17.75; the part number for this column would be SCA700-1775-SL176'
