Chainsaw Repair

........now the 1/2" 90's? usa model.

different design than the smaller sizes.  this one depends on a spring to move the pawl into contact with the gear.

gear is well made.

this wrench is sloppy.  it uses two rings to hold the pawl and gear in line.  one ring for the on/off switch, the other for the gear.  as the on/off switch ring grove wears...the switch becomes sloppy.  ring wear shown in photos.

the spring controlled pawl mechanism is not that good.  in one of the pics, i am pushing the spring/pawl down with screwdriver.

this would last normal users ok i guess.  i have been known to use a 4 pound hammer to help turn things a time or 10.  see photo.

the casting is very heavy and strong.  have used 2 foot helper pipe on these.

not worth rebuilding.  as the spring looses springiness......the wrench gets worse and worse.  take it back for another.  changing spring in this looks like a bear.
