124in. Engine Build (page 1)

Here I have flipped the case over and set it down in the same packaging. The case  half is wiped clean with acetone or lacquer thinner around the sealing edge, and a thin coat of hylomar is applied. Threebond, or clear rtv silicone can also be used. I have just always used hylomar. Case halves MUST be clean and dry, and checked for burrs, otherwise you just have a leak waiting to happen.



The next shot shows the pinion bearing, this is a precise fit piece and requires a bore gauge and laps to size the race in the case. However since this is new stuff from S&S, usually it only requires checking the fits and verifying the pinion bearing was shipped, and sized correctly. Parts aren't always interchangeable and this is one part worth getting right. So if you have a problem here, consult the manual, or the Harley manual or you will pay later. But it would take a book itself to describe this fit in its entirety, so I'll move on. The pinion bearing is slipped over the pinion shaft, and the retaining ring installed, with any sharp edges filed, and turned out. Installation is done with some retaining ring pliers available from snap-on or the auto parts store, same pliers used on exhaust flange rings. There have been quite a few bearing styles and thrust washer setups used here, but S&S tends to stick to this 94 and up style arrangement, not using thrust washers. As you can see from the straight pinion bearing, it is the timkins on the left case actually holding the flywheels in place...in the case...this side just "rides" the two woodruff key slots in the pinion shaft...and check them for burrs before the right side case is installed. they will be a bitch to get to later.



This picture shows the piston skirt cooling jets used in the SSW+ series motor...another adaptation from the twin cam, and the reason this motor will run 20/30 degrees hotter than a standard evo (aside from polish, and size). These are gonna cool the piston skirts. Keeping a cooler engine temp, at the tradeoff of higher oil tank temps. run an oil cooler.



O-rings are lubed with motor oil, and the cooling jets are installed with locktite. They are torx screws, and I have never been able to find a proper torque...so flatten out the o-rings and snug the screws up good, not the kind of thing you want falling off inside your motor. Blue loctite here. Now the right case is ready to be slipped over the pinion shaft and bearing. This case half I apply dry, since the other has the hylomar sealant. After slipping the right case is on I douse the pinion bearing good with assembly lube.



After slipping the case on I rotate it a bit left and right to make sure the hylomar is evenly dispersed before I start slipping the alignment studs and bolts in. Note that at this time, the flywheels have only been flipped over once. You want these to stay trued and don't want to jar them at all. Again, a little finesse is needed. Later you'll be glad.



Next just points out the end location of that pinion bearing retaining ring after right side case installation.

WOW! I'm about to contribute to CC again. The value of info like this... If everyone on here could pony up just $10.00 or so once a year... You'd all be getting a great value AND BigB would be able to afford all the redundant goodies so we would never go down...
