A crankshaft with cross-drilled main journals, such as the Pontiac 455, can maintain constant rod journal oiling while supporting the greatest load by using a main bearing set where the upper half is fully grooved and the lower half is solid. Most factory 3-inch crankshaft castings aren't cross-drilled, however.

It is important to discuss crankshaft hardening with the machinist which will be grinding your crankshaft prior to the weld and/or grind. These hardening processes can add to the size of the journals, so the crankshaft needs to be finish ground in such a way that allows for the expansion caused by hardening. ... Many ignore, or aren't aware of ...

Ford utilized surprisingly few crankshaft types in its small-block engines. The 221-, 260-, and 289-ci engines all used the same cast-iron crankshaft, making this crank widely available for three different displacements. This crankshaft is identified with a "1M" in the front journal area. While it's easy to assume the 289 High Performance ...

The arrows have no order, direction, or organised layout. They also aren't as close to each other as they could be. This in turn effects the over all strength and properties of the finished crank. But it is a quick process and the crank can be cast to pretty much near its final dimensions so minimal machine time is required.

"Let's just say we are asked to build a crankshaft for a 350 small-block Chevy. We've made a countless variety of 350 cranks, so it would have what we call a packet that includes all of the manufacturing information for our existing options," said Lieb."If a customer contacts us requesting a 350 crankshaft with a particular stroke and rod journal size, we …

size, so you can grind your 2.100 crank down to 2.000 to get smaller bearing sizes for reduced bearing speed and more power. While you're there, offset grind the crank to stroke it or destroke it for more or less cubes. If you start with a standard 2.100 crank, you can usually alter the crank throw by as much as 0.080 of an

Grinding away a layer gives a smooth uniform finish but this needs to be matched with undersized engine bearings. Counterweights need to be carefully checked if remachining a crankshaft and you'd be a fool not to check the bearings and that the crank is straight.

Crankshaft grinding. Regardless of what material the crankshaft is made of, sooner or later a working out is formed on it. At the earliest stages of wear, to extend the working life of a part, it is ground.

The reason you want the bars pointing to the operator (-.001) is that when you touch a crank with the steady rest top shoe during grinding, you will push it toward the centerline of the bearings. Now, change the indicator so it touches the top of the left hand measuring point.

In order to understand the working of the crankshaft grinding wheel, it is important to understand its functionality.
