Engine blocks

 

Rotating assembly

 

Cylinder head

An engine assembly can be broken down into its block, rotating assembly and cylinder head. Though the three are all important, the block houses the other two and is paramount to a successful engine rebuild. Here are the steps that any machine shop needs to perform on the block for any engine being rebuilt.

 

When the crankshaft is removed many shops just measure it for size to confirm if it is reusable and if it can be machined. If it passes that cursory examination it is assumed that it is ready to be reinstalled when the rest of the work is done. That is a mistake that can cause a good many headaches. The following are the steps your machinist should take to inspect a crankshaft.

 

The cylinder head is the most commonly serviced core component of an engine. This is due to its complexity of the operation of the valves, rocker arms and shaft (if used), valve springs, locks, retainers and guides along with the fact that this assembly of parts is exposed to both the liquid coolant and the majority of the combustion heat.
