Do not get closer than 6.4 mm (.25") to either end of the sleeve. If the weld extends to the end of the sleeve, the sleeve will be tack welded to the cylinder block. Also, move the electrode at a minimum rate of 406 mm (16") per minute so that the electrode does not burn through the sleeve and cause damage to the cylinder block.
These two welds will cause a separation between the sleeve and the cylinder block in the area between the two welds.
3. A standard tire iron can be used to make an FT1850 Chisel as shown in Illustration 2. The length of the new chisel should be at least 356 mm (14"). A drawing of the FT1850 Chisel is available from your Division Service Manager.

Illustration 2. FT1850 Chisel.4. Use the FT1850 Chisel to remove the section of the sleeve that is between the two welds. See Illustration 3.
A shoulder in the bottom of the cylinder block holds the sleeve in position. Use caution when the FT1850 Chisel is used so that this shoulder is not damaged.
5. After removal of the section between the welds, the remainder of the sleeve can be removed.
