    McMaster Spring Washer issue....

    Man, is anyone else getting low slip with the McMaster washers going around lately? I've went through 3 sets from 3 different sources with 1 source being this site.... So, by using all 5 they only hold as much, if not LESS, slip than OEM... I have to shim them to get 12 ft/lbs.

    This was on 3 different chargers too...
    I remember the 1st few sets I got a few years ago, you had to use 1 or 2 OEM washers to get the slip around 15-16 ft/lbs... Is Anyone getting the same results?

    are you measuring their thickness before you install? They should be 2.15mm thick, I've measured them new from 2.08-2.16mm thick...

    Measuring is needed, especially if you are reusing the clutches and gear...The OEM's can start at 2.15, but will quickly drop to 1.9's and 1.8's if they get hot...Also, how are you installing them? Just like OEM says, ()()( ?....Try changing their orientation to ((()(, or ()))(...Doubling 1 or 2 up will make a difference and will help them retain pressure...

    Also, how much wear on the clutches, gear, shaft flange, and flange nut will also make a difference......Recently I took my SC that had a rebuild kit done 3 years ago. Clutches, gear, and flanges were glazed and pitted...but it had 5 McMasters and it slipped at 150's when I removed it. I installed all new parts.....shaft, clutches, gear, flange nut, etc....but SAME WASHERS, SAME ORIENTATION, and it locked up at 340in ...I had to play with the orientation to get it to be 220's...Took it out the next day, ran great, got 1psi more ...Took it out, checked slip, same reading...

    Just measured 11 washers..
    1 = 1.95
    1 = 2.01
    3 = 2.03
    3 = 2.07
    2 = 2.09
    1 = 2.15

    I've tried all the orientations.. )())) being the best..

    Even if the OEM washers are old and I install the new Mc's, the slip is the same as the old washers..

    I've tried them on 20hr or less SC's..

    Throw in 5 of the highest you got, try ((((), and see what happens....If it locks up, change the orientation 1 washer at a time, see how much it falls.

    Go with these...
    2.15
    2.09
    2.09
    2.07
    2.07


    If you get it back to OEM orientation, and the slip is too high still, then swap out the highest for the next lowest....so take out the 2.15, toss in a 2.07, change the orientation, and start again...PIA I know! But thats how I do it to get it spot on...



    ....OH, and when you take them off, open the gap between the gear and clutches, pour some oil in there....NEVER check slip dry.

    I thought the washer next to gear is suppose to always be ( as Danny has posted.

    Just so you guys know, McMaster has a big problem with the washer losing there deflection rating when they get hot. My father works for a government research facilty and they use their washers, or did use, until they starting loosing tension under heat load which then caused the component to loosen and cause lots of problems. So they went with a different supplier. Just though I would let you guys know this
