- Wheel Skidders:
- 515 (S/N: 4LR1-UP)
- 525 (S/N: 1DN1-UP)
Description of Change: Two new turbocharger oil lines groups have been introduced in order to route oil directly to the turbocharger from the oil filter base. The new turbocharger oil lines groups will supply oil to the turbocharger faster at engine start-ups. The delivery of the lubrication oil to the turbocharger by these new groups is considerably faster than the previous groups. The filtered oil is routed directly to the turbocharger without routing the oil across the drilled passages in the cylinder block.
Adaptable To: The new 188-8949 Turbocharger Oil Lines Gp replaces the former 8N-2594 Turbocharger Oil Lines Gp. This change is effective with 525 Wheel Skidders with aftercooled engines (S/N: 1DN02103-UP) and adaptable to (S/N: 1DN01040-02102).
The new 199-6583 Turbocharger Oil Lines Gp is now available to replace the former 8N-2594 Turbocharger Oil Lines Gp for all 515 Wheel Skidders (S/N: 4LR1-UP) and 525 Wheel Skidders with nonaftercooled engines (S/N: 1DN1-01039).
When the turbocharger is replaced on all 515 Wheel Skidders (S/N: 4LR1-UP) and on 525 Wheel Skidders that were built prior to March 2000 (S/N: 1DN1-02102), replacing the turbocharger oil supply line is recommended.
Note: The 8N-2594 Turbocharger Oil Lines Gp, the 188-8949 Turbocharger Oil Lines Gp, and the 199-6583 Turbocharger Oil Lines Gp are nonserviceable at the group level. You must service the individual components. The components that are required for conversion to the new groups are listed in the tables below:
