    Default Dewalt DWE7491-XE - Crank will turn freely upwards but blade will not rise

    Hi all,

    My Dewalt DWE7491-XE - Crank will turn freely upwards but blade will not rise.

    Yesterday it was rising and lowering freely with ease.

    Today the crank will engage the blade height downwards.

    But the crank WILL NOT engage the blade height upwards.

    I'd like to repair this myself.

    If anyone has the DWE7491-XE and has fixed this themselves,
    could you please reply.

    Thanks in Advance
    Thanks,
    Barry G. Sumpter

    Ok just a few screws and bolts and came apart easily.

    The threads on the gear case have stripped.

    I'd like to get a matching nut and weld it just above the stripped thread hole.

    Any suggestions?

    What about a thread saver? These you can buy from Boltmasters and they screw onto the bolts thread making it bigger. Then you tap the stripped hole to match the larger thread saver

    Like Runningman said, thread repair in a nut is very easy. You just need to identify the thread type and size. If it is a standard size then a helicoil kit (or an equivalent brand) will fix it without much effort.

    Helicoil, that’s the one! Thanks Bohdan [emoji106]

    I rang boltMasters who don't stock the 14mm / 2mm thread nuts.
    They'd have to order them in as its not a common size they sell very often.
    grrrr



    Sounds like I need two taps.

    First is to widen the stripped threads hole.
    Then tap the widened stripped threads hole to match the insert/collet.
    Deducing the insert/collet has a thread on the outsize.

    Then tap the inside of the insert/collet to match my bolt thread.
    Unless the insert/collet comes in a m14/2mm thread side.

    yep: https://www.youtube.com/watch?v=9rtiFBC0wms
    Be sure to read the comments.



    Lot of mucking about in a tight space.
    Was hoping I would NOT need to remove the gear housing.

    Well duh, I can work from the bottom I think.

    Is there an epoxy for glueing the bolt to the housing?
    Thanks,

    When you get a kit you get the required tap and the inserts. You also need an insertion tool that reduces the insert diameter as you screw it in and then snaps off the little lug to trap the insert.

    I may have a helicoil kit that size at work if you have problems finding one. You are sure it’s 14mm x 2.0 pitch?

    Was speaking to dewalt to find out if they could tell me what the specs were.

    They had the presence of mind to ask me about my warranty.
    They looked up my serial number and told me it was covered.
    I'm not debating the issue.
    Going down to have it assessed.

    Trying to stay calm as I've got the worst luck and don't expect this to turn out well.

    Sounded better on the phone than in reality.

    Could have sworn they were talking like they could have a look at it straight away and tell me.
    Nope. 5 to 10 working days.
    So shocked I returned home after dropping it off I forget to ask about the control screw specs.

    I've left a message for their repair team.
    They will send me a message in reply.

    I swear this is the only tool I've purchased outright off the shelf.
    So was super surprised it was still under any warranty.

    Gonna have to find mitre saw projects to keep me busy.

    My other worry is that they will simple replace the part to be tread stripped again in a few years.

    At the very least other will be able to take advantage of this discussion.
    I'm sure I'll be returning.

    Now DEWALT are telling me it's gonna cost $250 for the repair.

    Since the saw didn't do it on its own.

    Told him it was a moving part.

    He told me it wasn't.

    I told him he was talking silly.

    He told me he was going to have his manager ring me and maybe I could talk him into repairing it under warranty.

    Whats up with that?
    Thanks,

    The joys of a warranty claim! Not worth its value on paper, from past experience with lots of things, hence why I don’t buy brand new cars
