POLINI engine cover for Peugeot with full support

The POLINI engine crankcase with complete support is designed to ensure high performance and versatility in mounting original or oversized cylinders. This component is ideal for those who wish to improve the efficiency of their engine, thanks to its ability to adapt to different configurations.

For installation, it is necessary to remove the engine block from the frame and completely disassemble the engine, ensuring that all parts to be reused are thoroughly cleaned. It is essential to heat the crankcase to about 250 degrees to facilitate its opening. During the process, check the crankshaft and the pin bearing for any signs of wear and replace them if necessary.

Assembly requires attention: after positioning the main bearings and heating the crankcases, the felt and seals must be installed, followed by the central gasket and the crankshaft, closing the crankcase evenly. It is important to install the fixing studs in the cylinder and check that the pin retainers are correctly positioned.

To optimize the carburation, the following values can be used:

Ø PISTON: 40.2 | CARBURETOR: PHBG 19.5 | MAIN JET: 76 - 78 | PILOT JET: 45 | NOZZLE: AN 262 | VALVE NEEDLE: W6 | STARTING JET: 30

Ø PISTON: 46 | CARBURETOR: PHBG 19.5 | MAIN JET: 80 - 82 | PILOT JET: 45 | NOZZLE: AN 262 | VALVE NEEDLE: W6 | STARTING JET: 30

Finally, to ensure excellent ignition, it is advisable to install the ignition unit, verifying that the timing is in accordance with the original. If you wish to increase performance, you may consider installing a Polini Motors Kit, available in different versions and displacements, along with a special exhaust. Always use original Polini Motors products to ensure maximum performance and durability of the engine.
