Tuning 695 Engine Project

Got home early today so I installed the crankshaft - not really very difficult.

As mine is a late model engine, the rear bearing is sealed using an o-ring rather than the paper gasket present on the earlier models. I coated the mating surfaces with Loctite so hopefully it will never leak :rolleyes:

The hardest bit was supporting the crankshaft while I installed both bearings. The bolts were torqued in a radial fashion to a torque of 15ftlb as suggested by my manual. I borrowed a Philips head adapter so I could torque the large cross-head screws.

The actual bearing surfaces were liberally coated with engine oil prior to assembly.

Tomorrow night I'll assemble the pistons, conrods and cylinders.

According to my "Haynes", forthe 650 '126' engine, the torque for the retaining bolts for the main bearings should be 22ft.lb (30 Nm. Con-rod bolts are tightened to 25ft lb (35 Nm) as are the flywheel bolts. Cylinder-head nuts are tightened to 29ft lb (40Nm) and the big crankshaft nut is 108ft lb (149 Nm).If you think that it will be of help to you, contact me direct ( [email protected] ) and I will send you a copy of my thoughts regarding the tuning of the 126 engine.
