Crankcase Assembly Tool

[Ron]

Thanks for the thread sizes! I'm going to try making a tool myself.

Not sure they are the same threads for every engine model. But certain for the late model water cooled 400, 430 & 500 2 stroke motors.

They are not as Husky (Sweden) made at least three different Crankcase assembly tools because of the different crankshaft lengths & thread sizes. I have two of the earlier ones, both have different threads sizes and spacer sizes.

I would be interested as well. Looking forward to pics.

I decided to build my own case splitter. Basically it's a harmonic balancer puller and a 3/16" sheet of steel. Will be making my patterns of the cases tonight to get the bolt locations. Hope this works right.

I still could use the assembly tool but I'll worry about that when I get closer to putting it back together.

Hey, falt black Rat,
How did your assembly go? Did you buy the crankcase tool? What other tools did you end up needing? I am about to tear into a 76' CR250 and am just looking for advice before I pay someone $1500 to do the job.
Thanks,
RayJ

I finally ordered the tool last week and got it in a few days ago. The build quality seems good and they had a deal with free shipping on $200.00 orders. Right now I just have the parts layed out on the bench in preparation for assembly, still haven't had the time to sit down and finish the job. I had also ordered a flywheel puller when I ordered the crank tool, but that was more for taking stuff apart than reassembly. With the shop manual it doesn't look like it will be too tough of a job to get it back togeather. Hope that helps.

Did you get the spacers with the tool ?

I did not get any spacers with the tool. The shop manual shows the spacers on the part that threads on in the tool diagram but makes no reference as to using them.

I know this sounds like a stupid question, but what do the spacer do? I'm normally pretty savvy with a wrench and a shop manual but am feeling like a total novice again here.

Nice thread. I thought I could share my tool aswell.

For drive side I simply welded a M10 nut to a M14X1 nut, turned it round and rust protected.
For right side I threaded a M12X1 left nut, welded it to a M10 nut, turned it round and rust protect

I then use threaded M10 rod to swap between the two and a 33mm OD / 26mm ID tube that fits on the inner race.

Took 1 hr to make, but works excellent

I had a pic on one of the adaptors (with a messed up threahed rod, used for welding alignment)

Here a couple pics of the one I built.

Very well done!

 

[Larsa]

Very nice tool Ron! Mine was more of a quick 'make from what you have' tool

I was very careful to only support the inner race of the bearing to avoid damage, but when I think about it I was probably overly conservative.

thanks,
Lars

 

[Ron]

Lars
I think your right on, you can easily damage a new bearing.
I did the same thing. Right where the tool rest against the bearing, I left a 1/8" ring the same diameter as the inner race. You can see the tool stands proud of the bearing in the second pic.

I got a copy of the mangle off eBay a few months ago. BSAnut is the seller and it was $150 for a very well made tool and cheaper if you do not have resources to build what you have seen here

 

[Larsa]

Ron, aaah, I see it now. Nice !

You're tool stands out in quality and robustness, but do I win in size ?

Lars

 

[Ron]

Lars, Yes you win, mine takes 3 hands to assemble. LOL
It took me a while to figure out how to pull the crank in while pushing with a t-bar.

Sorry to resurrect an old thread (no pun intended), but can anybody point me where to find an M12 x 1.00 LH tap, die, and/or nut? Nothing in McMaster, ebay, belmetric.com...
I guess you guys are cutting the threads on a lathe. I wanted a die to chase the crank threads, but I guess I can use a thread repair tool.

Try Andy @ Husqvarna Factory. Might have to get from UK.
