    Finding TDC on 2003 Indian Chief Powerplus 100 Motorcycle Best invention ever to find TDC. It was a snap to adjust the 4 push rods on my 2003 Indian Chief Vintage Motorcycle, with a Powerplus 100 cu. in. motor, After jacking the motorcycle up on a floor jack motorcycle lift, I put the transmission in 5th gear, then rotated the rear wheel until I heard the whistle on each of the 4 push rods (2 intake and 2 exhaust). That whistle told me that each valve was exactly Top Dead Center (TDC). It took more time (20 minutes required per valve spring) to bleed down each of the 4 valve springs before making the necessary wrench adjustments on the 4 push rods, than it did to find TDC. Before I bought this remarkable tool on Amazon, I could not adjust the the push rods like I can now. Great tool to have in your tool box.

    Worked great on a 5.0L Ford! Seems good. I used this the other day for the first time, to find TDC compression. It worked just fine. I don’t care for the lazy feeling of just pushing a rubber tip into the spark plug hole, but I suppose it was convenient. And it did work. It just doesn’t feel all that positive going in, leaving you to wonder if it will work. I used it on a 302 EFI Ford Mustang though, and #1 is at a bit of an angle to get at it. And yet it worked just fine. I would buy it again.

    Five Stars Worked great for me. Very useful.

  12. alanp

    super easy to use for finding compression stroke i bought this for finding the compression stroke on my small block. product works super easy. remove the spark plug and turn the engine over by hand or with the starter. helps when looking for TDC on the compression stroke- takes out the guess work.

  16. Jim home mechanic

  17. Alan L. Young

    Great tool to have Works like its suppose too. No need to put thumb over hole to determine comp stroke.

  18. Amazon Customer

    Must have tool I’m a professional aircraft mechanic and have inspector authorization. I need to put an engine I’m inspecting on TDC on the compression stroke for each cylinder to check compression. This tool saves me time which is money. I have two of them.

  19. David

    Does its job perfectly Gets you a rough estimate of tdc. I used it in a few diesels using the glowplug hole. It saved a lot of time pulling a valve cover. It isnt perfect, you will then go to a dial indicator setup before timing the pump.

  20. ROBERT STOKES

    works used to check when cylinder pistion at top dead center
