124in. Engine Build (page 1)
As a preface...this may show you some terms and tools needed, but it is nearly impossible to note everything, Nor is it possible to document each check of fits made. This is a GENERAL overview...and maybe it will either help you get the knowledge you need before you actually attempt it....or dissuade you from tearing into the project. it is only meant as an order of the process, not an actual manual to follow.
Ok guys....this is what you are dealing with...a box full. This is a 124 S&S super sidewinder plus motor, unassembled and carbed. This picture shows the box of goodies you have to deal with.
Next, using some gun brushes to remove any polishing residue left behind in the right case half as well as cleaning out oil pump passage, if not you might as well just throw some sand in your oil tank and buy a new motor. Parts must be deburred where needed, and cleaned immaculately. I use about a case of brake kleen for each motor...and all passages are blown out with air. Special attention is paid to threaded holes, which should be chased with the thread chaser....and also alignment stud holes...bolting the case halves together. You don't want aluminum chips or polishing rouge in there giving false torque readings.
Now with the cleaned case half....wiped dry and blown out with air...ready to install the flywheels. As you see there is a Timken bearing race...outside....
This is the inside of the same left case...another Timken race....these are coated with some assembly lube prior to installation.
Now for the Timken bearing spacer. This comes as part of a matched bearing set...that is designed to keep the bearings apart at the proper distance...for the machining done where the races are installed.
Late style flywheels used in these motors, the gear tooth look is an adaptation from the factory I believe, but its purpose is to count the flywheel rotation...hence the name of the sensor used, the crank position sensor. In this motor, I'll be using a crane hi-4 and carb, so that feature really wont be incorporated.

TRUST NO-ONE
You put a lot of time and effort into compiling all of the pictures and describing the process.
Thanks for all you've done for the members here, Brad!
