Cylinder Block Assembly/ Engine Assembly

Cylinder Block Assembly/ Engine Assembly

Purpose of Task:

To have the understanding of being able to reassemble an Engine, not only to put back together but to know what needs to be torqued.
To have everything in working order so the engine runs smoothly with out the pistons getting jammed, the crank shaft, cam shaft valves, rockers etc, are freely moving.

Assembly:


Before connecting the crankshaft, the Bearing/ Bearing Shells need to be checked and replaced if need be.
Fitting the main bearings:
These need to be well lubricated & all bearing bolts need to be torqued at 50% of the specification.

Video on how we put the Pistons back in.

























Putting the bearing shells back on, The two groove need to line up together.






Picture on the right and below are showing torque tightening.
Note that there is specific Torque specs for different engines







Torquing with the torquing ratchet

Never fully tighten the cylinder head bolts with a standard ratchet, a torquing tool is required 
Picture above & video below is of torquing the cylinder bolts
There is a specific order in tightening the bolts, starting from the inside working out.



 Putting the timing belt on, the tensioner needs to be loosened to get this back on
