  • Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

125-200cc 125 flywheel pulling

is sucking so far, ive been trying to pull the damn thing for a half hour with no luck. i even got the little puller tool from halls and its not helping any.

the tools the type that its a bolt basicly with a hole drilled in the center of the threaded side so it pulls on the flywheel and pushes on the crank. this isnt my favorite style of puller, i like the tusk style much better but its what they sent me so ive got to make it work.

basicly it looks to me that the bore on the puller is to deep and its not pushing on the crank at all and its just bottoming out on the flywheel. ive tried putting a couple washers in the hole so the puller will hit the crank but its still not popping loose, this thing is stuck pretty well.

im not wanting to try heat but if i have to i will, ill try soaking it in penetrating oil over night and see how things go in the morning.


ps anyone else run in to this yet?
 
Once you get it cranked down, tap the end of the tool a couple of times with a brass mallet. That often does the trick.
 
Yes,

I had the same puller and it is made to be used with a small ball bearing that fits in the center. I tried all kinds of things to space it out and no luck. I ended up leaving it as is because I was able to adjust timing with it on. But you really need to find an appropriate ball bearing for it to work. I think the types of spacing that you and I were using end up binding and not actually applying direct force to the shaft. I actually used an aircraft locking nut with the rounded side in and it just flattened it out like a pancake. Way tight.

PS, If I have to I will drill out the puller, tap it, and install my own pusher/Tension shaft.

Yep DirtDame that often works but I was "tapping" with a little too much enthusiasm and still no go.
 
it would have been nice if there was a supplied BB with the tool i bought....

ive tried the tapping method too and had no luck.
 
ok, its still stuck on there.

i tried the BB trick and i even used the BB and tapping trick with no luck.

ill bring home one of those mini torches from work tommorow and se if that will help perswade it any.
 
Doesn't it always make you "nervous" using heat on a flywheel.:eek: I will go to great lengths to avoid it but when they epoxy it on at the factory what are you going to do. Hope I never have to take mine off because it is just as tight as yours.

Good luck,
Walt

PS, Have you thought of drilling and tapping a couple of holes in the flywheel and using a standard puller that you can really get some force on? Bad idea?
 
well ive heated a bunch of things. some times it just takes a little heat and a bit of tension to perswade things to move.

no im not scared to heat it a bit. im not gonna turn it red just put a mini torch to it for a minute or so. then put the BB and puller back on there.

im not drilling holes because the would very likely throw everything out of balance, on a high revving engine thats a very bad thing.

red and green locktites are designed to not break loose until heated.

still, if this was my kx i would have had this damn thing on and off 20 times by now. frustrating.......

oh well, maybe tomorrow night ill get it off and be able to take it to the shop and have them put on new bearings and put the new rod on too. then i can get to putting other things together and be ready for new years.
 
Yep I have done the heat thing too, it just makes me nervous like performing wiring in my pumphouse that is 480 volt. I know the circuit breaker is thrown but when you are dealing with that kind of potential it just makes you nervous. No I am not an electrician but I play one on the golf course and do all the wiring and panel work myself.

ok got it apart, needed to apply a little bit of heat.

put the puller on, impacted on it a couple times. tapped on it, impact again and it popped off!

wow the mag on this little guy is strong as hell!
