Special Tools You Can Make
Flywheel Holding Tool
A fl ywheel holding tool can be made out of an old
junk fl ywheel ring gear as shown in Figure 2-1, and
used in place of a strap wrench.
1. Using an abrasive cut-off wheel, cut out a six
tooth segment of the ring gear as shown.
2. Grind off any burrs or sharp edges.
3. Invert the segment and place it between the
ignition bosses on the crankcase so the tool teeth
engage the fl ywheel ring gear teeth. The bosses
will lock the tool and fl ywheel in position for
loosening, tightening, or removing with a puller.

cranksha may be made out of an old junk connecting
rod.
1. Find a used connecting rod from a 10 HP or
larger engine. Remove and discard the rod cap.
2. Remove the studs of a Posi-Lock rod or grind off
the aligning steps of a Command rod, so the joint
surface is fl at.
3. Find a 1 in. long capscrew with the correct thread
size to match the threads in the connecting rod.
4. Use a fl at washer with the correct I.D. to slip
on the capscrew and approximately 1 in. O.D.

capscrew and washer to the joint surface of the
