Another Italian followed me home...

Oh man. That sucks. And is funny.

I’m no longer allowed to work in my shop while distracted...

This bolt was SO EFFING TIGHT! the impact wouldn’t budge it, it didn’t move until I broke out a 4’ cheater bar and held the engine still inside the bike frame. BOOM! She broke loose!....

Suddenly I realize, it was a LEFT HAND THREAD!! What an idiot!

We've all done something like this. Can't say I've ever heard of the nut actually breaking, though! Congratulations!

Where was that nut?

It goes on the right side of the crank, holding on the main gear. Luckily I didn’t ruin the crank, I’m not sure how I dodged that bullet.

 

[Tonkaman]

I have to say that this engine is made of much higher quality parts than my Honda was. Even the bits and bolts are noticeably better materials.

I unwrapped my new engine cases and was over-joyed to see that they come fully loaded with hardware, bearings, and seals! Wow Beta, you rock!!

They are the same way on KTM 2 strokes.

Those cases are PRETTY!

I totally should have known better, but I just wasn’t thinking clearly. I wish that the service manual would have mentioned it.

They sure are!! I’ll be honest, I wasn’t excited to have Phil sledgehammer my bearings again

 

[Tonkaman]

Does anyone know if this rod should be bent? It looks like it’s supposed to be bent, but I figure it doesn’t hurt to ask.

 

[anderson750]

I would say yes since it seems to follow the shape of the case but I know zero about Betas so my opinion is still nothing better than a guess.

I agree.

Those were my same thoughts till I saw these service manual pics. Still hard to say for sure... I suppose the worst it could do is stop the PV from opening an extra mm or two?

 

[Tonkaman]

I finally got the proper flywheel removal tool last night and was able to split the cases. Everything inside was in beautiful condition, no metal debris of any sort and hardly even discolored a paper towel when wiped clean. Since the new cases already had bearings, seals and a few random other goodies I was able to squish them right back together. Not bad for an hour of spare time.

 

[jeeper]

Wow, look at how clean your work surface is..

 

[Tonkaman]

I made the mistake of greasing up all the linkage and swing arm bearings. I say mistake because they were all in great shape still.

The problem I’m having though is that the seals were all seized in place pretty bad. I can’t even budge the seals in the swing arm! I’ve completely destroyed one trying to get it out, and still no luck!

How Can I pull a bearing seal that won’t move by prying/punching it out?

 

[Greg]

Take a propane torch and heat up the area around the seal.... had to do that on a swingarm bearing/seal recently.

Awesome advise, thank you!

Will this work to pull seals without damaging them? Like for future inspections?

I doubt it? Seems like most used seals come out destroyed.
