NOTES

Cylinder studs are easily damaged. Install lengths of ½” ID. rubber or plastic tubing over each stud to prevent nicks and scratches until top end is



assembled. Do not use studs as handle to lift or position crankcases.

Unlike early style stock cylinder studs which rely on interference t between threads of case and stud to hold them in place, S&S studs have standard



thread t and are secured by combination of thread tension and thread locking compound. Late style stock studs, H-D #16937-85C, have same design.

*All reference to Harley-Davidson® part numbers is for identication purposes only. We in no way are implying that any of S&S® Cycle’s products are

original equipment parts or that they are equivalent to the corresponding Harley-Davidson® part number shown.

Seemingly insignicant damage to studs may cause stress risers which can lead to stud failure and possible damage to engine



components.

Insucient thread engagement between stud and base nut or stud and engine crankcase may result in thread failure and major engine



damage.

Thread failure due to insucient thread engagement could cause violent engine disintegration under power, resulting in loss of control of

motorcycle with serious personal injury.
