      @@DIYwithMichaelBorders According to the Bravo 3 manual I recently got access to, the bearing retaining ring nut should be tightened to 200ftlb using a torque wrench on the special tool itself, and using a conversion chart to calculate the actual torque setting for the torque wrench, given the wrench is inserted into the special tool in the 1/2" square in the handle, not working directly on the ring nut. That's a lot of torque which also raises the question as to how the one you removed, came loose with just a few blows with a rubber hammer.

      We highly recommend following your serial number Bravo service manual and if it states 200ft-lb, it’s important to apply that torque to alleviate any damage or premature failure.

      Thanks for the reply. 200ft-lb is on the higher end torque-wise. Most alpha outdrives will call for a lower torque value around 150-180ft-lb however it’s very important to get your exact value for your exact serial number outdrive from service manual.
      We installed the newly designed Press-fit gear and bearing kit and used the new rolling resistance procedure set forth by Mercruiser for the new kit.

  • @TheCommo81
    @TheCommo81 Рік тому +2

    Good video but I am confused on something. You say the pre-load is supposed to be 6-8 inch-lbs. my Mercruiser manual (18-03200) on section 10-18 states to "tighten the locking nut to a torque value of 85 ft-lbs." Which one is it? 6-8 inch-lbs or 85 ft-lbs? There's a huge difference between those 2 values for setting a pre-load. Also, your micrometer is being measured in nM, not inch lbs. I'm hoping you drive doesn't fail due to improper torque settings.

    • @DIYwithMichaelBorders
      @DIYwithMichaelBorders  Рік тому +2

      Thanks for watching, 85ft-lbs will be for the standard bearing kit while the new (Press-fit) bearing kit will be set using rolling resistance.

      @@DIYwithMichaelBorders Thanks. I contacted mercruiser regarding it also because I was confused. They told me whether it was a pressed gear or factory gear the rolling resistance should be 6-10 inch lbs! When installing back into the sterndrive and tightening the castle nut back on, The castle nut should be torqued to 200 ft lbs, however there is a chart to use when attaching your torque wrench to the castle nut wrench, you have to measure from center of torque wrench socket drive to the center of handle and look up on the chart. Different lengths have different values. My torque wrench is 15 inches, so torque on castle nut will be 111 Ft lbs when connecting torque wrench to the castle nut wrench.

    hey @DIYwithMichaelBorders should there be play in and out. Like I can push the driveshaft against the gears and pull it out about 1/4 in when I turn the driveshaft and u-joints. I just took the outdrive off my boat because I was looking to see where I had a gear oil leak. There was gear oil in my bellow.

    • @DIYwithMichaelBorders
      @DIYwithMichaelBorders  Рік тому

      Thanks for watching, great question. We take it you have separated the upper from the lower and are referring to the inner driveshaft that is secured to lower unit through water pump and below.
      There will be a very slight amount of play as you pull shaft up and push shaft down however to much play is not good.
      1/4” is on the absolute high end of play and any more that that, it can cause damage to seals and gears.
      Are you planning on replacing seals?

      @@DIYwithMichaelBorders no I wasn't planning on replacing the seals. But didn't know if that was the cause of gear oil getting into the bellow. But no I haven't taken the outdrive apart. I was just holding the driveshaft that attaches to the u-joints and goes to the motor.

      Thanks for the reply, you’re referring to the Yoke Shaft that feeds through the bellow/hull and into the engine coupler.
      There should be no play with that shaft. Your outer retainer nut may have loosened slightly and allowed the 1/4” play which in return, beat up your seals…hopefully no more that that…
      Yoke Shaft assembly will need to be pulled out and seals replaced as well as a very closed and detailed inspection of the gears and bearings.

      We recommend following your exact service manual for your outdrive.
      If your manual states to torque the original bearing and gear set to 70ft lbs, we strongly recommend doing that as it ensures you’re following the engineers instructions.
      However if you’re transitioning to the new designed gear and bearing, you will follow the rolling torque instructions set forth by your manual.
      Below is a link to our video explaining in more detail the difference between the two.
