1. Adjustment of the control lever
(1)Perform idling with the control lever (A) contacting the pushrod (B). At this time, confirm that the spring (C) is not compressed by control lever (A)'s operating torque.
(2)To set the stop position, compress spring (C) using the control lever (A) and adjust the rack so that it contacts the guide screw (D) at position L2. Then, set and fix using the lock nut (E). Adjust the rack position L2 at this time using the shim (F).
(3)Confirm that the control lever (A) returns to the idling position when pulled in the stop direction and then released.

Introduction
The problem that is identified below does not have a known permanent solution. Until a permanent solution is known, use the solution that is identified below.Problem
There have been some isolated instances of issues with the Diesel Particulate Filter (DPF) on certain C3.4B engines.Solution
Caterpillar is aware of this problem. Follow the procedure that is detailed below.
Table 1
Required Tools
Tool Part Number Part Description Qty
A 233-7191 Hose Cleaner Gp 1
Obtain a fuel sample from the engine.
Obtain a lubricating oil sample from the engine.
Attach a copy of the full service history of the engine to the Service Information Systems (SIMSi) report. Include the change history of the following components:
Engine oil
Engine oil filter
Engine fuel filter
Crankcase breather filter
Ensure that the breather element is clean and free from wear or damage. Replace the breather element. Refer to Operation and Maintenance Manual, Engine Crankcase Breather Element - Replace for the correct procedure. Ensure that the inlet hose is clean and free from restriction. If the inlet hose requires replacing, refer to Disassembly and Assembly, Crankcase Breather - Install for the correct procedure.
Determine the service hours of the engine air cleaner element. Ensure that the engine air cleaner element is clean and free from wear, damage, or restriction. If necessary, replace the engine air cleaner element. Refer to Operation and Maintenance Manual, Engine Air Cleaner Element (Single Element) - Inspect/Clean/Replace for the correct procedure. Ensure that the hose assemblies are clean and free from restriction and dust.
Inspect the inlet and outlet hoses of the turbocharger for the presence of excessive lubricating oil. If necessary, take photographs inside both inlet and outlet hoses. If necessary, take photographs inside the compressor housing for the inlet and outlet. If excessive lubricating oil is found, replace the turbocharger. Refer to Disassembly and Assembly, Turbocharger
