A D-Pin Removal Tool, Installation Tool, and Receiving Tool, see Special Tools Section
of this publication.
DISASSEMBLY
1. Remove the U-beam assembly. Follow U-beam Assembly removal procedure in this section.
NOTE
On PRIMAAX EX models built after September 2010 or equipped with the enhanced U-beam
Assembly, it will be necessary to remove the existing sealant and tamper resistant cap for the
support beam/cross tube connection to proceed with the bolt removal. Carefully remove sealant
with a hand scraper as to not damage the U-beam assembly.
2. Remove the support beam/cross tube connection bolt from the end of the beam.
3. Remove the end cap (if equipped).
WHEN SEPARATING THE U-BEAM ASSEMBLY, PROTECT THE CROSS TUBE BY PLACING A PIECE OF
PLYWOOD AGAINST OR CARDBOARD AROUND THE CROSS TUBE. CAREFULLY DISLODGE THE CROSS
TUBE FROM THE SUPPORT BEAM WITH A LONG HANDLED SLEDGE HAMMER BY APPLYING BLUNT
FORCE ON THE SUPPORT BEAM DIRECTLY IN FRONT OF THE INBOARD TOP CORNER JOINT. ALL
BLUNT FORCE MUST BE APPLIED FLUSH TO THE THICKEST PART OF THE SUPPORT BEAM, SEE FIGURE
8-14. FAILURE TO STRIKE THE SUPPORT BEAM SQUARELY MAY RESULT IN COMPONENT DAMAGE,
PREMATURE FAILURE AND VOID WARRANTY.
4. Place a piece of plywood or cardboard around the cross tube prior to applying blunt force
to the support beam.
5. Dislodge the support beam from the cross tube by hitting the support beam directly in front
of the inboard corner joint. The support beam and cross tube joint requires shock load on the
support beam, at the joint, to dislodge the two components. All blunt force must be applied
flush to the thickest part of the support beam at the inboard corner joint, see Figure 8-14.
Continue striking the support beam until it is completely dislodged from the cross tube.
