Engine Disassembly


After Mike brings the engine into the engine room, he inspects the engine for any external cracks or damage and starts by removing the old spark plugs.


The manifold is removed and inspected. If it is in very good condition it will be sold as a used part. A new manifold will be installed on the engine during reassembly.


Mike removes the water pump. It is discarded and replaced with a new pump later.


Next, the pulley is removed…


And then, the timing gear cover is pulled.


The governor Mounting plate is removed…


And it's finally time to remove the head bolts and cylinder head.


Not all head gaskets come off this easily.


Now, Mike can flip the engine over and remove the oil drain plug.


Then, the oil pan is removed.


Remove the main caps…


Then the rod caps.


After the crankshaft is lifted out, it's a simple matter to pull the (4) pistons.


This is where it starts to get a little trickier. Each of the valve assembly retainers must be removed…


Before Mike can carefully drive out the valve assembly (remember the engine is viewed upside down).


The valve assembly is removed and discarded…


And the cam simply slips out.


Now Mike carefully sets up our custom built "sleeve puller".


Here you can see a "partially" removed sleeve.


You can see that Mike has removed the second sleeve from the right. When the final sleeve is removed, the components are ready for the machine shop.
