How To Split The Cases And Replace Crank Bearings (part 3)

Transcription:

This is part three of the split cases crank, and crank bearing video. Please refer to parts one and two for the previous procedures.

In part two we installed the crank into right case half, and now we're going to install the transmission. It's important to try to do this as an assembly with your shift forks installed, everything lined up. We actually made this look easier than it is. It actually can be kind of tricky.

You want to make sure that everything rotates smoothly. You can tell that the gears are lined up where they need to be. It won't be possible to shift through the gears at this point, until the other case half is on, but, you should be able to tell that everything lined up.

Now we're going to get ready to install the other case half, and some machines have gaskets, other machines just require a liquid gasket. Here we're using Yamabond. Make sure sealing surface is very clean before you start. Make sure you put sealant on both halves.

Now we're going to go ahead and slide that on. Be really careful and make sure everything is lined up correctly before you start pulling the crank through. Make sure all the shafts are starting to fall into the bearings. You want to make sure the cases are parallel. We're going to go ahead and install our crank puller installer back onto the crankshaft.

We use the right pieces. Put the outer piece on. Thread the nut on. And as we tighten this, once again we want to make sure everything is parallel and the case haves are coming together, together. Make sure they're parallel, we might need to take a rubber mallet and tap the back, just to make sure everything comes together nice and even.

Now we're going to go ahead and put our bolts in. Here we're just illustrating how to tell if your bolt is the right length or not. As you put them in they should all stick out about the same before you tighten them. We're going to go ahead and tighten them now. We're going to use maybe a crisscross pattern to make sure there's no warpage. We don't want to develop a leak between you center cases.

We're working on the other side of the case. We're going to start installing our shift mechanism. We've put a little medium strength thread locker on our star shift detente. Make sure our shift pauls are in there, the springs are all together. We want to install that as an assembly.

Now we're going to slide our shift shaft through. Make sure everything lines up. This is our kick start idler gear, there's a little washer on there. Then we're going to use our Tusk circlip pliers to install that circlip. Just going to use a screw driver to seat the clip into the groove, then we'll move on to the primary drive gear.

There's normally a spacer, normally there's multiple gears to either drive the water pump or power valve. Slide those on. Now we're going to move on and put the outer clutch basket on. That's our washer, our sleeve and our double bearing.

We're going to put our inner hub on with our lock-washer, and the nut. We're going to use our Tusk clutch hub holding tool. And go ahead and torque our clutch hub on. Now we're going to bend up our lock washer. Now we're going to wedge our aluminum washer back in there, so we can tighten up that primary gear. Don't forget to remove the washer.

Now it's time for the inner clutch cover. Make sure everything lines up. Your water pump needs to line up on a gear, sometimes you need to move things back and forth a little bit to get it to line up correctly.

We're going to go ahead and install the bolts. Again it's all ways a good idea to go ahead and use a crisscross pattern. Now it's time for the clutch push rod, or lifter rod. And the clutch lifter itself with the thrust bearing. Then we're going to start installing our clutch plates.

We're going to go ahead and do it just as they came out. Then our pressure plate goes on. Put our springs on our bolts. This ones going to go a crisscross and gradually. Once again you want to make sure it's nice and flat. We're going to put our outer clutch cover on. Once again, in a crisscross pattern. Now we can go ahead and install it in the frame. We're going to kind of jump ahead.

We're installing our stater plate with our K&L impact driver, make sure those are nice and snug. We need to put our clutch actuator arm back in, and its set screw. Now we're going to install the flywheel using our Tusk clutch hub holding tool. It also doubles as a flywheel holder. Tighten that nut up. We'll install our ignition cover and that completes the bottom end.
