]I'm rebuilding a customers swing boom on his log skidder. The boom was made by Esco who no longer sells or supports them. Parts are n/a.
I need to find or have made a new spur gear & rack. It just swings the boom from side to side. I was quoted $9000.00 by Rush gear to have a replacement made. Can't put that much money into just two pcs. Anyone got any ideas or suggestions before I search for other quotes? I'm assuming that most places would be in the same price range for custom gears. I have searched for something in a "stock" size but coming up empty.
Gear is 3 pitch, 11.8125 od x 3.125 id x 3" wide with a 7.5" x .5" deep counter bore on one face. The rack is 25"+/- long x 2.75"w x 1.875 deep. I think it is just mild steel as it grinds & cuts like it.
As a last resort I may try to have 1/2" thick plates water jet cut & then laminate them to make a gear & do the same for the rack.
gear welded to post.

gear removed.
