The Ariens Company has learned that the splitting wedge mounting bolts on the model 917001 27-Ton Log
Splitter may fail under extreme loads. Replacing the two existing .38-16 hex bolts closest to the cylinder
with two .50-13 x 2 Grade 8 hex bolts (p/n 05970700), two .563 x 1.38 x .109 flat steel
washers (p/n 06442000), and two .50-13 center lock nuts (p/n 06536300) reduces the potential for failure
under such loads.
Before putting into service any 917001 27-Ton Log Splitter in the above-listed serial number ranges,
replace the two.38-16 hex bolts closest to the cylinder as indicated in the illustration on page two with two
.50-13 x 2 Grade 8 hex bolts (p/n 05970700), two .563 x 1.38 x .109 flat steel washers (p/n 06442000),
and two .50-13 center lock nuts (p/n 06536300). For units in these serial number ranges already sold to
end users, contact the customer and replace the hardware at the customer’s earliest convenience.
Only the units in the serial numbers listed above need to have hardware replaced. All other units will have
had this change made before shipping from Ariens.
Dealers should file a warranty claim for each log splitter they service, using flat rate code 17900. Dealers
will be reimbursed for 0.25 hours of labor at their standard posted shop labor rate.
Refer to the illustration on page 2 for hardware location and installation instructions.
