New design of steering column release

The improved design of the release head with the new 338-1508 Gas Spring Gp will provide increased reliability. The improved design will provide adequate travel at the stop bolt to allow full movement of the foot pedal to actuate the release head. The jam nut on the gas spring has Loctite applied to prevent loosening of the jam nut.

The improved design is adaptable to the following machines:

  • 416E (S/N: CBD1-6207; SHA1-7296)

  • 416E ST (S/N: BWC1-340)

  • 420E (S/N: HLS1-8370; KMW1-3299; PHC1-933; PRA1-1585)

  • 422E (S/N: DSK1-652; HBE1-2951)

  • 428E (S/N: DXC1-803; SNL1-5515)

  • 430E (S/N: DDT1-907; EAT1-1473; RLN1-419; SCD1-374)

  • 432E (S/N: BXE1-4598; RXS1-545)

  • 434E (S/N: FSH1-1625; SXB1-251)

  • 442E (S/N: GKZ1-825; PCR1-183)

  • 444E (S/N: HXB1-175; LBE1-805)

  • 450E (S/N: EBL1-444)

The improved design is effective with the following machines:

  • 416E (S/N: CBD6208-UP; SHA7297-UP)

  • 416E ST (S/N: BWC341-UP)

  • 420E (S/N: HLS8371-UP; KMW3300-UP; PHC934-UP; PRA1586-UP)

  • 422E (S/N: DSK653-UP; HBE2952-UP)

  • 428E (S/N: DXC804-UP; SNL5516-UP)

  • 430E (S/N: DDT908-UP; EAT1474-UP; RLN420; SCD375-UP)

  • 432E (S/N: BXE4599-UP; RXS546-UP)

  • 434E (S/N: FSH1626-UP; SXB252-UP)

  • 442E (S/N: GKZ826-UP; PCR184-UP)

  • 444E (S/N: HXB176-UP; LBE806-UP)

  • 450E (S/N: EBL445-UP)
