Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

I've always had luck just starting the new one in the hole, and wiggle the rake back and forth while pushing down, the old just falls out and the new pops in.

I use a little different approach. I remove the key and spark plug wire. Then I get on my knees (no remarks please) and turn the impeller slowly until I can line up ther holes. Much better contol to get there quickly and put the holes in a position where you can get the best swing with the hammer.

It would  be wise to have a punch handy, they're not very expensive, if the bolts are rusted in you will need it. Take the replacement shear pins to a local hardware, Sears, or Home Depot and ask somebody for help if you're unsure for the appropriate punch. You'll fix the problem with less stress and have the punch when it happens again.

I would just add that when you're buying shear pins to replace the broken ones, get an extra set while you're there. 

The suggestion to grease and rotate the augers is a very good one, as Marty (Majorxlr8n) and I can attest to. 

Good Luck

sheer pins or bolts...

tape a couple extra ones to the handle .

you will always have them.

wrenches and hammers and punches are easy to find but those darn sheer bolts are lost as soon as you put them down.

also curious that you have 4 sheer bolts in one machine...can you elaborate.

snow--
    new mtd's have quad-sectional augers, each section has it's own shear pin, erego 4 shear pins.  It's hard to see in the pic below, but if you look clse you can see the section break between the augers:

yes i have seen those models ,just havent worked on them yet.

looks like a good idea with the extra spiral on the augers,should provide a more consistant stream of snow to the impeller.

found the head to a shear pin in the yard and realized that it had broken.  do not know when it had occurred.  (first storm? last storm?)

 most of the screw and  the nut were still in the shaft.  (and the rake was still only spinning w/ the shaft.)

Anyway  replaced it w/ the info from his thread.....starting w/ the tick list given by marc .

it was a realllllllllllllllllllllllllllllllll pain to get the old one out. the old one was bent. after a while  decided to remove the nut. that caused the screw to break in a second place.   that removed some of the bent screw shaft(?) and it finally came out.

Thanx
