Some of the alternative repair methods are as follows.
Individual details
If the inspection has shown that the engine block and most of its components are in a condition that allows them to be further used, the most economical alternative is to purchase only the necessary spare parts and parts. Carefully examine the cylinders, crankshaft and pistons / connecting rods. Even if there is only minimal wear on the cylinder, the cylinder bores should be ground.
Replacing the piston group
If the inspection showed that all parts have a lot of wear, we recommend replacing the piston group with a new one, rather than buying parts separately. The piston group of the factory configuration includes sets: pistons, rings (compression and oil scraper), piston pins, retaining rings.
Replace with a set of connecting rods. If necessary, if the connecting rods do not have deformations and mechanical damage, you can replace the bushings for the piston pin, but after replacing it is necessary to expand the hole to the required diameter (fit piston pin).
The crankshaft after a thorough check must be replaced or reground to the next repair size.
Carefully consider which option best suits your needs and discuss the situation with a workshop or auto shop and more experienced repairers before ordering or acquiring replacement parts.
It is much easier to disassemble the engine and work with it if it is mounted on a portable stand. Such a stand can be rented for a very reasonable fee. Remove the flywheel/drive plate from the engine before mounting the engine.
If you do not have a stand, you can disassemble the engine by fixing it on the floor or table. Be extremely careful not to drop the engine when handling it without a stand.
If you intend to purchase a remanufactured engine, you must first remove all external components in order to transfer them to the purchased engine, in the same way as if they were installed on an engine that you decided to rebuild yourself.
Attention: When removing external components from the engine, pay close attention to all parts that may be useful during installation. Note the position of all gaskets, seals, bushings, studs, brackets, washers, bolts and other small parts.
