Angry Airens 924000 8 hp blower

I am trying to replace Wheel Axle Bushings but cannot get the axle out. My model has the "wheel lock" on one end which allows one to unlock the wheels so it will turn around easier . Then it can be locked for straight line use. There is a "groove pin" through that mechanism. At least the IPL calls it a groove pin NOT a split pin. Must I drill that out to remove the axle? Or am I doing something wrong.

There is a cotter pin holding the axle lock in place on 924027 and similar machines which is essentially a split pin where the ends are separated for retention. It appears that you can leave that in place and remove the wheels and axles after removing roll pins on the axle assembly.

Looking at the parts diagram there are 4 roll pins on the axle assembly, which consists of right axle with hub, axle shaft and left hub and a differential. But the number of roll pins used on the axles seem to vary by model number. The sizes are 3/16 x 1 and 3/16 by 1 and 1/4 on the left axle and 3/16 by 1 and 1/4 and 3/16 by 1 and 1/2" on the right axle. The roll pins are punched out in 2 parts, a large punch to reach the axle and then a 3/16" punch to drive through the axle. A roll pin is made of thin hardened steel and wound into one or several thicknesses and it acts like a spring so friction holds it in place. Very difficult to drill out due to hardness and shape.

Good luck.

Once You get the Differential Lock off, the remaining roll pins in the axle can be difficult to remove. Use a Torch and penetrating oil to make things easier. OR, you can cut them off with a whizzer wheel. Getting them out with the axle removed from the machine can make it easier. GL
