Detroit Series 60 12.7L Valve Adjustment Chart
Accurate adjustment of clearance between valve buttons, intake and exhaust valves is important if maximum performance and economy are to be obtained. To ensure efficient engine performance and extended valve and injector service life, an initial valve lash and injector height measurement/adjustment requirement has been established. Effective immediately, the valve lash and injector heights… Read More »
Series 60 – Testing the Cylinder Block (Immersion Pressure Method)
Use cylinder block pressure test kit (J–36223–D) for immersion method pressure testing as follows: 1.Install cylinder liners with new seal rings and crevice seals. Refer to section 1.23.3. Seat the liners firmly in the block counterbores with cylinder liner installation tool (J–35597–A). 2.Install two metric eye bolts (J–35595) in the head bolt holes at opposite… Read More »
Series 60 – Cleaning the Cylinder Block
Before removing cylinder liners for block cleaning, the liner bores should be gaged to determine whether liner replacement is necessary. Refer to section 1.23.2.2. Remove cylinder liners with the cylinder liner removal tool (J–45876) before putting the block in cleaning or descaling baths, to avoid trapping cleaning agents in block liner seating bores. See Figure… Read More »
Series 60 – Removal and Disassembly of Engine from the Vehicle
Before mounting an engine on an overhaul stand, it must be disconnected from the transmission. Details for removing an engine will vary from one application to another. However, the following steps will be necessary, regardless of application: 1. Disconnect the battery cable(s) from the battery(s). 2. Drain the cooling system completely by removing the drain… Read More »
Series 60 – CYLINDER BLOCK AND CYLINDER LINER
The cylinder block is the basic engine structure, establishing and maintaining the alignment of all engine working parts. In the Series 60 Engine, the cylinder bores are not an integral part of the block casting, but are in the form of replaceable, wet type cylinder liners. See Figure 1-1. Flanges at the liner upper ends… Read More »
Series 60 – DDEC V
The DDEC V ECU receives electronic inputs from sensors on the engine and vehicle, and uses the information to control engine operation. It computes fuel timing and fuel quantity based upon predetermined calibration tables in its memory. DDEC V provides an indication of engine and vehicle malfunctions. The ECU continually monitors the DDEC V system.… Read More »
Series 60 – DDEC III/IV (Series 60G Engine)
The DDEC III/IV ECM receives electronic inputs from sensors on the engine and vehicle, and uses the information to control engine operation. Fuel is controlled by DDEC. See Figure 6. Portable equipment facilitates access to diagnostic capabilities of DDEC III/IV’s. The Diagnostic Data Reader (DDR) requests and receives engine data and diagnostic codes. This equipment… Read More »
