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 The previous version was outdated and no longer supported.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

Removing Flywheel on 09 TXC 450

Is there a trick to this or is it just on there really tight? We have tried a flywheel puller by hand and with an impact with no success. Any suggestions? We're going to get a different puller and find a better compressor and impact, but I just hope I'm not missing something obvious. The manual just says remove the flywheel...sounds straightforward enough!
 
I just removed the FW off my 08 TXC250 and because it was so tight (?), it sounded like a gun went off when it popped off ... So I'm guessing it is just very tight ...

Just tighten up the puller and maybe tap on the FW with a rubber hammer at the same time ... maybe spray some WD40 or something around the crank \ FW junction ...
 
Tighten the puller down, then hit the head of the puller bolt straight in with a good size ball-peen hammer a time or two and repeat until it pops loose. Depending on what type of puller you have, make sure it stays square to the FW and shaft. Don't let it try to pull off center. This all applies to anything you are pulling to remove.
 
Thank you both for the advice and reassurance. A friend is helping me do my first top end on a motorcycle. It has been a fun learning experience.

Fairly easy stuff in most cases ... timing will be the most interesting and difficult part ...

Maybe post some pics of what you are doing ...
 
We finally got the flywheel off last night. The ball peen hammer suggestion seemed to do the trick, though it still put up a really good fight.

Timing actually wasn't all that bad. I read through the Foolproof Cam Timing thread multiple times before I started. The hardest part is that two of the dots used for alignment of the cams are hidden behind the case. We marked the wheel edge above the dots with a paint pen and it was then easier to align. Of course, we haven't started it up yet....

The latest development is that one of the bearings on the intake cam is toast. We both looked at the cams when we took them off and somehow missed it, but fortunately saw it on reassembly. I imagine now, that the bearing was probably the source of the increased noise more so than the cam chain. Oh well, it will all be shiny and new now. I'm hoping to find somebody that cam replace the bearing rather than having to buy a whole new cam.

I wish I had taken some photos. I had planned on documenting the whole process, but once my friend started helping, I didn't want to waste his time by taking a billion photos.
 
Called around and found a few places that indicated they could replace the bearings. Up-Tite and DJH as well as a local guy that used to work for a Ducati dealership. I decided to go with Up-Tite because George just really seems to know his stuff and took the time to discuss the quality (or lack thereof) of the OEM bearings.

If you have a older generation motor like the 2009 450s, then I definitely recommend checking those bearings for play every so often, especially if your engine has become noisier. The wheel-side bearing on the intake cam was probably only a ride or so from releasing ball-bearing mayhem into the motor. :eek:
