• Developed from the 29MT design ¿ of which there are more than 1.25 million OE units installed ¿ the 31MT provides virtually full coverage for the Class 6 & 7 commercial vehicle aftermarket.
• This model features positive shift engagement. In the case of tooth abutment, the armature rotation in full power clears the abutment to allow pinion engagement. The benefit is zero click-no-cranks (CNC). This is well suited for high start/stop vehicle applications.
• The 31MT is highly corrosion resistant due to improved brush holder plating and stainless steel springs.
• A number of design changes to the hardware, including the commutator, O-rings and bearings, as well as the lamination have resulted in the 31MT being one very robust starter.
