Piston rings
Piston rings |
1. |
Push the piston rings down into the cylinder one by one, using a piston to position them correctly.
|
2. |
Measure the ring gap using a feeler gauge, see illustration. If necessary, the gap can be increased with a special file.
Regarding measurements, see
Pistons

Matching in worn cylinder bore |
1. |
Insert the piston rings one by one into the cylinder bore all the way down to the lower dead centre, where the cylinder diameter is the smallest. Use a piston to obtain the correct ring position.
|
2. |
Measure the ring gap using a feeler gauge, see illustration. If necessary, the gap can be increased with a special file.

Fitting piston rings on piston |
1. |
Clean the piston ring grooves in the piston with an old piston ring.
|
2. |
Check the piston ring clearance in their respective grooves in the piston. Regarding measurements, see
Pistons
.
|
3. |
Use a pair of piston ring pliers when fitting rings on the piston, see illustration. The lower compression ring must have the side marked "TOP" face up.
|
4. |
Rotate the piston rings so that the gaps are offset 120° to each other, see illustration.
