Diagnosis help

I pulled a balancer apart and I noticed that the springs are quite strong.

The way they work is bi directional. So if out push on one end or the other it will push against all 3 springs at the same time.

Each spring took about20 lbs to compress!! Heavy little things.

If you look at the front and back of the engine you can see a notch cut into the one part of the case and a hole in the other half of the case. You could use a bolt and nut to push the cases apart.

Those are the spots for the actual spreader tool.

There is one in your first picture just under the mount hole beside where the timing chain is flopped over.

I don't really understanding how you would do this. Are these the holes you're talking about?

Nope those are anchor points for lifting the engine. It looks like that casing doesn't have the the same thing for spreading the cases as the newer cases do.

I wonder if taping the case with a rubber mallet in the direction that would separate them would do it. I've done it with a mallet and piece of wood. Just be careful and choose a spot to hit that is strong. Once it starts to move its just a matter of moving from back to front. All the bits stay in the top end and only a few things stay with the bottom end.

So lay it down with the bottom facing up.

I tried a firm tap with a mallet and wood, it didn't help. It's a stubborn one.

Ok I found a pic with one of the pry holes:



On the upper crankcase in the right of the pic, about the middle of it you can see the rear pry hole.

You only just need to get them cracked a little, then keep going with your mallet.

There are dowels that align the cases, so you need to separate them evenly all the way around if that makes sense.

On mine, I had to get a very large flat blade screwdriver between the cases, but if you do this be extremely careful not to damage the sealing surfaces.

I dont think this case has those pry points pete.

[droyce]

Yep, my cases look different. Ill have to get cracking on this thing. I got swiped by an old guy tonight so Im bikeless now untill I get one of them back together.

[Guest]

What about using a long bolt in the bottom half of the back of the engine and one in the top and use something to lift between these two points?

[droyce]

SUCCESS!!

[Guest]

Excellent, let's hope you can find the source of that noise!

Any news on this ?
Last I saw was a video on the starter clutch gear.

Unfortunately no. After getting it torn down it got put on the back burner. I have three other projects and I go to school part time. Along with work I just don't have the time to invest.
