Install the conrod end cap bolts. If the engine had other pistons to install, follow the same procedure. Ensure every part is running correctly. The piston installation process is now complete. While the piston installation process described here may appear simple, it chances of making a mistake are many. Pistons are sensitive engine parts, and one wrong step could cause problems. To ensure everything goes as expected, follow these rules.
Piston installation can be done in simple steps, but only if you know how to do it right. Also, if you have the right tools and materials. While the procedure itself is important, the preparations you need to make are even more crucial. These involve sizing the piston and the cylinder bore. For that, check our piston measurement article.
It explains the process to obtain the dimensions for clearance, size, and other aspects. Save my name, email, and website in this browser for the next time I comment.

Information on use. Clean the sealing area of the engine block thoroughly of fragments of gaskets if it was not reworked during the reconditioning. Clean all tapped holes carefully from dirt, oil and coolant agent which may still be there. Carry out all cleaning work before installing the pistons in the cylinder. Wet all surfaces on the piston with fresh engine oil — do not forget the piston pins and connecting rod bearings.
Note the direction of installation of the piston installation markings on the piston crown, valve pockets. Clean the cylinder bore again with a cloth and also wet this with engine oil. Check your piston ring scuff band for damage and dents and remove them or replace the tool if necessary.
During piston installation, ensure that the piston ring clamp or the conical assembly sleeve lies flat on the cylinder head sealing face. Do not install the piston in the engine without using a fitting tool risk of injury, risk of ring breakage. A large amount of pressure must not be necessary when installing the piston. If a piston cannot be pushed into the cylinder, always check the piston ring clamp.
Do not turn the opening of the clamp so that it lines up with the joint ends of the rings. When using a hammer handle for installation, only the weight of the hammer may act on the piston crown. Never use the hammer to drive the piston into the cylinder with force.
If the piston rings do not break during installation, they can still be bent and can no longer fulfil their function completely later during engine running. Installation using force not only damages the rings, but can also damage the piston.
This is particularly the case for pistons in petrol engines. This is done by inserting the ring into the cylinder and pushing it down, somewhat.
Applicable to all rings: Ring gap 0. Stagger piston ring gaps so that they are approx. Piston rings must be installed with a ring expander to prevent piston damage or ring breakage. Piston rings must be installed in the piston so that the "TOP" marking on the ring faces up, i. Insert piston pin retainer on the flywheel side first.
Inspect and install piston pin. The piston pin is held in the piston through interference fit. If the piston pin can be pushed into the cold piston by hand, use a pin of larger diameter.
A color code marking inside the piston on the piston pin boss indicates the proper size of the piston pin, as follows: white - OOO8 in to 0. If the clearance a pproaches the wear limit of 0. Install the cold, oiled piston pin in the piston which has been heated to 80 deg C deg F through immersion in hot oil or application of the e1ectric piston heater, in which condition the pin should slide into the piston under light pressure; the pin should be pushed through, to the pin retainer, in one continued move.
Install second pin retainer. The pin retainers must fit well in their groove within the piston pin boss.
