REGULATOR ASSEMBLY

TEMPORARILY TIGHTEN HYDROGEN SUPPLY REGULATOR ASSEMBLY

Note

To prevent damage to seal portions or threaded portions, and to prevent openings from being contaminated by dust, metal fragments, etc., do not remove the protective caps of piping connection areas included with new parts until immediately before performing the procedure.

Lift Upwards

Set

While slightly lifting up the hydrogen tank tube joint supply bracket, set the hydrogen supply regulator assembly to the hydrogen tank frame FR CTR.

Note

Do not damage or deform the No. 4 hydrogen tank tube or the No. 5 hydrogen tank tube.
Temporarily tighten the hydrogen supply regulator assembly to the front center hydrogen tank frame.

TEMPORARILY TIGHTEN HYDROGEN TANK TUBE JOINT SUPPLY BRACKET

Temporarily tighten the hydrogen tank tube joint supply bracket to the front center hydrogen tank frame.

TEMPORARILY TIGHTEN NO. 6 HYDROGEN TANK TUBE

Note

To prevent damage to seal portions or threaded portions, and to prevent openings from being contaminated by dust, metal fragments, etc., do not remove the protective tape from the seal portions, threaded portions, and openings of the No. 1 hydrogen tank assembly and hydrogen tank tube joint until immediately before performing the procedure.

To prevent damage to seal portions or threaded portions, and to prevent openings from being contaminated by dust, metal fragments, etc., do not remove the protective tape from the seal portions, threaded portions, and openings of the hydrogen tank tube joint until immediately before performing the procedure.
To prevent damage to the seal portions and threaded portions, and to prevent foreign matter such as dust or metal fragments from entering the openings, do not remove the protective caps of the new hydrogen supply regulator assembly until immediately before performing work.
Temporarily tighten the No. 6 hydrogen tank tube to the hydrogen tank tube joint and hydrogen supply regulator assembly.

FULLY TIGHTEN HYDROGEN SUPPLY REGULATOR ASSEMBLY

Fully tighten the 4 installation bolts of the hydrogen supply regulator assembly.

Torque:

13 N*m { 133 kgf*cm, 10 ft.*lbf }

FULLY TIGHTEN HYDROGEN TANK TUBE JOINT SUPPLY BRACKET

Fully tighten the 2 installation bolts of the hydrogen tank tube joint supply bracket.

Torque:

13 N*m { 133 kgf*cm, 10 ft.*lbf }

FULLY TIGHTEN NO. 6 HYDROGEN TANK TUBE

*a	17 mm Union Nut Wrench Fulcrum Length
*b	Torque Wrench Fulcrum Length

Using a 17 mm union nut wrench, fully tighten the 2 union nuts.

Torque:: Specified tightening torque; 25 N*m { 255 kgf*cm, 18 ft.*lbf }

Note

To prevent the tube from turning together, hold the tube in place while tightening the union nut.

Tech Tips

Calculate the torque wrench reading when changing the fulcrum length of the torque wrench.
When using 17 mm union nut wrench (fulcrum length of 30 mm (1.18 in.)) + torque wrench (fulcrum length of 255 mm (10.0 in.)):

22 N*m (224 kgf*cm, 16 ft.*lbf)
