Suzuki GSX-R 1000 Service Manual: Piston ring removal and installation
Removal
- Remove the piston. Refer to “engine bottom side disassembly” .
- Carefully spread the ring opening with your thumbs and then push up the opposite side of the 1st ring to remove it.
| Note do not expand the piston ring excessively since it is apt to be broken down. |
- Remove the 2nd ring and oil ring in the same manner.
Installation
Note

- Install the piston rings in the order of the oil ring, second ring and top ring.
- the first member to go into the oil ring groove is
the spacer (1).
After placing the spacer, fit the two side rails (2).
| Caution when installing the spacer, be careful not to allow its two ends to overlap in the groove. |

- Install the 2nd ring (3) and 1st ring (4) to piston.
| Note 1st ring (4) and 2nd ring (3) differ in shape. |
| Note face the side with the stamped mark upward when assembling. |
- Position the gaps of the three rings and side rails as shown. Before inserting piston into the cylinder, check that the gaps are so located.
