Service Magazine, SEPD0788, 13 June 2005, "Corrections To Steering System Pressures - Test and Adjust". Disregard this article. See the replacement article that follows.Testing and Adjusting, RENR5189, "TH220B, TH330B, TH340B, TH350B, TH355B, TH360B, TH460B, TH560B and TH580B Telehandler Steering Systems", "Steering System Pressures - Test and Adjust"

Changes have been made to tolerances on the pressure in the hand metering unit. The new tolerances will minimize the adjustments to the hand metering unit. The new tolerances became effective in production in the following machines: (S/N: SLA669), (S/N: SLB1184), (S/N: SLC747), (S/N: SLD1107), (S/N: JRK570), (S/N: SLE3717), (S/N: SLF1643), (S/N: SLG1008) and (S/N: SLH566).

In the "Steering Pressure Test" section, the tolerances in the Table 2 have been changed. Replace the former Table 2 with the following Table 2.

Table 1

Steering Pressure
Model	Pressure
TH220B, TH330B, 340B, TH350B, TH360B	16250 ± 1000 kPa (2350.0 ± 145.0 psi)
TH460	19250 ± 1000 kPa (2800.0 ± 145.0 psi)
TH560B S/N:SLG1-675	16250 ± 1000 kPa (2350.0 ± 145.0 psi)
TH560B S/N:SLG676-UP with axles 231-0707 or 231-0708 231-0709 or 231-0710	17750 ± 1000 kPa (2600.0 ± 145.0 psi)
TH580	17750 ± 1000 kPa (2600 ± 145.0 psi)

In the "Steering Pressure Adjustment" section, Step 4 has been changed. Replace the former Step 4 with the following Step 4.
