    Metrics challenged.......4MM

    Getting ready to start using the RC 2060 Rotary Cutter that I purchased last year. Its not been used since last summer and has been sitting outside. It has a slip clutch instead of a shear bolt and I understand that I need to loosen the bolts that hold the clutch plate and bellville spring together and make sure that it slips to protect my pto drive. Once that is accomplished I need to adjust the six bolts back to a 4 MM gap. Thats where I am metrics challenged. Looking at a feeler gauge .016 is also .406 MM. Is that 4 MM plus the 06 or is the .406 a bit less than one half of a MM ?

    A .406 mm feeler gauge is 4 tenths of a millimeter, plus 6 thousandths of a millimeter.
    You would need roughly 9-10 of those to equal 4mm.
    4mm = .15748 inches, or just a hair over 5/32".

    google says


    3mm = almost 1/8 inch. 4mm = 5/32 inch (= a bit over 1/8 inch) 5mm = just over 3/16 inch. 6mm = almost 1/4 inch.

    there has been a few other threads on pto clutch settings ands there are many YT video's.


    Most seem to just count the turns of the bolts vs. measuring the gap..

    Seems like the gap will be the thickness of clutch plate but prehaps its recessed somehow..idk.

    0.016 inches = .4064 millimeters

    .406 millimeters is a little less than half a millimeter. This is roughly 1/10th of 4 millimeters. To measure a 4 mm gap, you need a small ruler, micrometer, or caliper. 4 mm is too big for any feeler gauges that I've seen. You could make a feeler gauge this big, but I've never seen them available as everyday tools.

    Thanks all! Ordered a easy to read MM ruler. Was thinking I needed a feeler gauge of some sort but looks like they measure the gap at the edge of the two flanges! The 4 MM Allen wrench might work as well. Thanks again.

    1mm=0.0393701". If your working on something in your shop, that's a lot of numbers to multiply in your head! Round off to .04. 4mmx.04=.16". As stated above, the exact number is 0.1574803" and 5/32 is .15625". The easiest "feeler" would be a 5/32 drill...use the end that goes into the drill with NO burs! If you want to get really, really, crazy accurate: with a 5/32 drill loose in the gap, you should NOT be able to insert a 0.0015 feeler next to the drill.

    I've got fraction, number, and letter drills and use these often for "measuring" various metric conversions. I've got'em, they're handy, and close enough! Bob

    P.S. I hardly use a calculator anymore. Google does math and conversions from the search box (typed or spoken), and Alexa does the same with verbal requests. Try them out!

    Even better I've got most of them memorized along with the fact that 1mm=.03937 inches or 1"=25.4mm.
    This along with the decimal equivalent of fractions down to 16ths and most of the 32nds.
