Ford's Two hundred eighty nine small-block engine uses a as well lucid master, nevertheless mistakes in the building course can even be fabricated. Maybe the most habitual mistakes when rebuilding a Two hundred eighty nine consist of failing to confirm that the timing gears are aligned properly, and installing the pistons and connecting rods backwards. Last of all, the force of properly lubricating the cutting edge components with engine lube cannot be overemphasized.
Timing Gear Installation
The Two hundred eighty nine uses two timing gears and a timing chain to insure that the valves within the cylinder heads and the Glimmer plugs are properly timed. Whether those gears are not installed exactly, the engine Testament not begin and, in latest cases, the engine Testament nowadays bend the valves and possibly damage the pistons. The larger gear attaches to the front of the camshaft, while the smaller gear attaches to the front of the crankshaft. A groove is located within the inner circumference of the crankshaft gear, fini which a metal gloss on the gratuity of the crankshaft slides finished to effect that the gear is fitted properly. On the face of the camshaft gear is a immature, Hand-bill indentation, which serves as an alignment site. To clinch that the gears are properly installed, the metal vital at the gratuity of the crankshaft gear must be directly howl the indentation stamped into the camshaft gear. An imaginary wrinkle should cross both points.
Piston and Connecting Rod Installation
Because most, if not all, of the components within the engine are new, the components are particularly susceptible to wear if not properly lubricated. For that reason, it is important to lubricate the critical moving part within the engine with assembly lube, particularly the camshaft, crankshaft and connecting rod bearings. Assembly lube, as opposed to engine oil, is specifically designed to lubricate those components when the engine is first started, and should be liberally applied. One number is stamped into the connecting rod itself, while the second number is stamped into the connecting rod's cap. Both numbers are identical, and must face the same way when installed.
The Importance of Assembly Lube
The most critical time of any engine overhaul is the period when the engine is first started.Upon cardinal glance, there does not arrive to be any antithesis between the sides of the 289's pistons or connecting rods. Upon closer inspection, you'll civility a insufficient groove on one side of the top of Everyone piston. That mark must face toward the front of the engine to ensure that the piston is installed properly. The connecting rods are similarly marked, but with a number rather than a notch on one side of the base of each connecting rod.
