Assemble H-arms

Main Arms

• [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 - then work on the eye alignment.

Eyes

• 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 of tractor arms.
• Weld eyes in place.
• Weld 1" rebar reinforcement.

Cross Arms

• 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.
• Tack DOM in place upon alignment.
• Raise arms.
• Check for alignment, and realign if needed.
• Tack DOM gussets
• Insert mounting eyes into arms, and insert 1" shaft inside eyes to align them.
• Move through the range of rotation of the QA plate to confirm alignment.
• Tack in QA plate mounting eyes in place with shaft in place
• When aligned, finish tacking.
• Weld H-arm assembly to completion.
• After welding, grind and clean as needed.
