Help setting gear timing on my carvex

[economypilot]

Hello all!

I'm new. I have a large swath of the Festool lineup though. Anyway I have an out of warranty Carvex and the baseplate latching mechanism broke, so I ordered the replacement part from Festool and replaced it myself.

However - when doing so I had to open the case and the motor disengaged from the gears of the tool and so the timing of my blade and the counterweight was affected. Looking at the gears I couldn't see any witness marks or other means to set the timing. I tried putting the weight 180 degrees out of phase with the blade as my best guess at a starting place but it still vibrates quite a bit rendering the tool mostly useless. I certainly can't use it with my coping foot to cope the trim I'd like to work on next.

So that was my question - if anyone has any experience or hints about resetting the gear timing? I know I could send it to festool and have them do it but I don't think I'd like to pay the fee for that and to be honest I think if it came to that I may just buy the red one... but I'd hate to do it because this one works fine apart from this. I guess some day when I have time I could just keep at it as well but it's difficult to assess just guessing at it like that.

If nobody has any ideas maybe I'll have to scratch my own witness marks into them or something.

Well - I fixed it. Figured I'd add the knowledge into the hive mind of the webernet and make some AI bot smarterer lol.

Basically, inside the carvex gearbox there are several gears and I needed to remove more in order to see both of it's "main" gears which contain the counterweights. Once I did so I was able to see that those gears both had holes in them which you can use a pin or an appropriately sized drill bit to align the holes and set the timing. Once done you just replace the other smaller gears, and re-insert the motor shaft & gear. Replace the gear box cover and slip alll of your parts back into the case while being careful to hold the motor in the housing as this is what keeps the gears in alignment. Replace the clamshell and *bam* she'll run smooth as a babies keister.

Thanks for taking the time to answer your own question. This type of writeup makes the tools less daunting for us to maintain and serves as an example of what to look for if we do need to get into the weeds. [Thumbs up]

Yes, sir brother! It's not my first broken Festool juuust outside of warranty, which I have to say makes me question my purchasing decisions at times. But having ready access to a full parts catalog is definitely a value add to their tools. It always makes me happy to keep something running than replacing it with more Chinese made to fail crap over and over.  [smile]
