Basic cylinder base wrench kit
Cylinder removal and installation of small bore TCM engines with reduced dimension
nuts requires two standard cylinder base wrench sizes 5/8" and 9/16". Middle
cylinders will require an additional 5/8" cylinder wrench to tighten the through
stud. Our cylinder base wrench kit includes 2 ea. 5/8" and 2 ea. 9/16" wrenches.
This kit is for O, IO-470 engines.

** As the cylinder(s) on a through stud are removed, the through stud needs to be
retightened to prevent movement of the crankshaft bearings. Never leave a
through stud un-tightened! Damage can result.
