Assemble H-arms

Main Arms - build main arms, hang them on tractor, but do not weld anything until cross beam and bottom are aligned.


 * [2] Cut 4-1/2” piece of 1-7/8” DOM.
 * [2] Cut 3-1/2” piece of 1-7/8” DOM.
 * Mark position of loader shaft for diameter of DOM.
 * Torch loader shaft, considering that 1-7/8” DOM gussets are used.
 * Measure location of loader arms on frame.
 * Torch loader arm location in frame.
 * Place gussets in tractor frame.
 * Fit 1-7/8” shaft through gussets.
 * [2] Mount 1-7/8” washers outside of frame and inside of arms.
 * Insert DOM gusset into loader arm.
 * Mount 1 loader arm at a time onto the shaft.
 * Align both arms to rest on the bottom of the frame without any welding - then work on the cross arms - bolting them together while retaining alignment of bottom of arms.

Cross Arms - fit in cross arms, tighten, and then fix the pivot and QA pivot to retain alignment.


 * Cut 54" cross arms.
 * [4] Cut 1/2"x4"x6" angle - 6" long.
 * Drill 3 holes on long side and 2 holes on short side.
 * Long side goes on cross arm, shoft side goes on main arms.
 * Measure location for mounting of cross arms on the main arms.
 * Fit and clamp the cross arm in place.
 * Transfer punch hole locations on one side of loader arms.
 * Take loader arms off one by one.
 * Mark other side of cross arm-mounting bolt locations.
 * Annular cutter mag drill through main arms.
 * Remount main arms on 1-7/8" shaft, use washers and 2 double split collars
 * Align them
 * Fit cross arms and bolt them on, using metal lock nuts.

Eyes - with cross arms tight, make eyes align, 


 * Cut [2] 3x7x1" pieces with bandsaw.
 * Weld pieces together.
 * Drill eye hole in weldment.
 * Torch out a 3"x 1" slit in loader arm top.
 * Cut piece of 1" rebar for inside of arms, reinforcement.
 * Insert 1" shaft through both eyes
 * Tack weld eyes and DOM pivots in place.
 * Raise arms to make sure they clear the frame.
 * Check for alignment, and realign if needed.
 * Weld eyes and DOM pivot in place.
 * Weld 1" rebar reinforcement in eyes.
 * Move through the range of rotation of the QA plate to confirm alignment.
 * After welding, grind and clean as needed.
