Cylinder block Kit disassembly
Disassemble the cylinder block kit
1. Pull to remove the slipper retainer (K049) with the pistons (K050) from the cylinder kit.
The pistons are not selectively fitted, however units with high hourly usage may develop wear
patterns. Number the pistons and bores for reassembly if they are to be reused.
2. Remove the ball guide (K047).
3. Remove the 3 pins (K046).
Most repairs do not require block spring removal. Perform this procedure only if you suspect
problems with the block spring.
