Things to avoid doing when you are building motors


My dad tore down a 51 panhead motor today and it was filled with poor workman ship. It must have been put together by some hack in his garage. Anyways, I took some pics of the blatantly obvious substandard repairs so I could show you guys what not to do in your motors. The tapers for the crankpin in the flywheel were worn out, so the flywheels were too close together and consequently the rods did not have enough endplay. It looks like some bozo ground the sides of the rods with a makita grinder. If you click on this picture and zoom in, you can see the few spots where it was still touching the flywheel thrust washers! what a hack job. These rods are s and s rods and are too heavy anyways, so we will end up replacing them with something that is closer to the same weight as oem rods.


NEVER use silicone on anything. IT is the worst sealant of all time. It was invented by the devil to clog up your oil pumps. This is very hard to clean, but can be fixed. You guys will save yourself a lot of heartache if you throw away any existing silicone tubes that you have and use good sealer.



I think that the theory behind putting this fitting in, was to cross thread it so that it wouldn't vibrate loose. what a joke.
