• 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 The previous version was outdated and no longer supported.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!

TE630 engine removal and rebuild

Hmm. Apparently the 630 is different. Here's mine.

I've removed the stator since this pic was taken, but there is a bearing in there.
 
Yep, the 630's have a bearing to support the end of the crankshaft. Part No. 8000 02124. Doesn't help you to get it out though!

I would try heating the cover in the oven to 150-200C and spray some Loctite Freeze and Release on the bearing. It may shrink it enough to drop out.
 
I've had success in similar situations with an appropriate sized concrete anchor.

I tried the heat and freeze method, not with the Loctite stuff tho. Might give the concrete anchor a try before dropping $80 on the tools.
Thanks Guys.
 
Tried the anchor, no go. 3/8ths is a little too loose to get a bite, and 1/2" won't fit. Going to give one more try with a 1/2" that I make fit. Bread didn't work. Actually tried playdough first, but it just extruded out of the bearing. Bread did the same, although with more resistance. Sigh.
 
Damn it. Filed down a 1/2" anchor and got it seated well and it took a few good hard blows before the anchor popped out, bearing still stuck. Here's a photo of the playdough/ bread attempt.
 
I'd try the 1/2 inch anchor again after heating the cover. Then I'd get the shits, and probably destroy the cover to get the bearing out!
 
Got it hot. Hit it hard. No luck. Still slipped out. Off to Amazon to buy more tools. At least I get a new tool :-)

I used a large crescent wrench under the washer, and blocked the case on the leg of the bench and my foot, and wailed on the wrench to try and pull the bearing out, but the anchor just didn't have enough bite on the id of the bearing.
 
Look closely at post #2 of this thread- posted by markjenn. I had an older LC4 KTM and this bearing was prone to failure, and removal very difficult. If you look very closely at his pics (especially further down in his post) you'll get the idea- it's all about the "puller hooks." Perhaps a mini version of this using well hardened materials will do the trick.

Looks like a small crack in the casing at around the 6:30 mark in the first pic...you know- the pic of the weird baking experiment. That's my ignorance though- not sure what the bread is supposed to be doing to help.

Good luck man. We're rooting for you.
 
Yea, no replacement for the proper tools when the going gets tough. Worth trying the cheap/free tricks when the tools are 100 bucks + tho. That's a small crack, but it's not through and doesn't leak. Result of the shifter impacting the out side of the cover during a spill.
 
If it was my bike, I would drill two 1/8 inch holes in the cover, corresponding with the outer bearing race, and knock the bearing out with a thin punch. Then plug the holes somehow. Thats me though, and I am a tightarse!

I agree. Now- just in case there was confusion- post #1 of that thread shows the proper/expensive tool and post #2 shows the home fabbed version. Thinking some form of that might be of help.
 
if the bearing is sealed fill behind it with grease, get a reasonably close fit shaft and put it in till it feels snug, then hit it
this is the method to remove clutch throwout bearings
iy acts in a hydraulic method
make sure the case is well supported before hitting
 
So how have matters progressed. I have been a silent snoop so far but am enthralled and want to go the whole 9 yards so kindly kill the suspense. What has happened with the stator bearing
 
Tried all the cheap tricks to get that bearing out without luck. Purchased a blind/pilot bearing puller complete with slide hammer and a little heat added, still no luck, it's fn stuck. Wife had surgery, so I've been 2 weeks tending to her and the kids, and I'm traveling this weekend, so I likely won't get back to it for a week or so. Going to try baking it, cooling the bearing, and the new tool together. If that doesn't work, I'm sending it off to my buddies to weld a 1/2" threaded rod in the middle and I'll pull it out that way.
