(146.1) Bore 4 And 6 Cylinder Engines The 5P6595 Insert (1) can be used for the repair of cracks in the seat for cylinder liners of the above engines, when the cracks are too large for repair with the 5P1625 Insert. The new insert is larger in diameter and has a design that will put any stress over the main walls of the cylinder block. This will help to prevent any more cracks in this area.Tools Needed
Parts of the 5P1618 Tool Arrangement and other additional tools are needed in the installation procedure of the cylinder liner seat inserts. Tools needed are given below. Drive Assembly Maintenance
(1) Assemble tool holder (1) on boring tool (2). Make sure the tool holder slot is down and both the pilot on the boring tool and the pilot on the tool holder are clean. Install the washer and nut. Tighten nut (3) to 50 5 lb.ft. (70 7) torque. (2) With the boring tool in the horizontal position, remove plug (4) and check the oil level in the hydraulic feed unit. Fill the unit with SAE10W, 20W, or 30W oil. Install plug (4). Loosen knob (5) to release the feed control valve and move tool holder (1) in and out several times. Remove plug (4) and again check the oil level. Fill with oil if necessary and again install plug (4). Tighten knob (5). If the oil level is low, the tool will not cut smoothly. (3) Check the adjustment of 6V4984 Ball Spring Screw (6). To make an adjustment, tighten screw (6) until it is tight, then loosen it 1/4 turn. If it is still difficult to install a cutting tool, inspect screw (6). It is possible that screw (6) is worn and a replacement screw is needed. It is also possible that 6V4985 Cutter Holder Plate (7) is worn and is the cause of tool drag. Inspect the inside of holder plate (7) and install a new holder plate if necessary.
Failure to keep the correct tension on the cutting tool with adjustment of ball spring screw (6) can result in a different depth of cut each time a tool is removed and installed.
Installation Of The Boring Tool On A Cylinder Block
All studs and dowel pins on the top surface of the cylinder block, in the area around each cylinder liner bore, must be removed so there will be enough room to install the boring tool group and make the counterbore needed for insert installation. Use a 2P5535 Stud Remover Group, 8S1378 Stud Remover Group and the 5P944 Dowel Puller Group for stud and dowel removal.(1) Use a file to remove any rough places from the top surface of the cylinder block. Clean the top of the cylinder block to make it free from all foreign material. Also make sure the cylinder liner pilot bore is clean and free from all foreign material. This is necessary because the boring tool uses this area for alignment. If it is
