Convert a Lawn boy mower lower bushing to a needle bearing
In this video I bore the lower crankshaft bushing out to accept a needle bearing, I do this with the Jet milling machine, and a criterion boring head. Then I heat the casting to 250 degrees for 1 hour and install the bearing with the help of a rubber mallet.

    I have to compliment you on your efforts to provide light and camera angles that closely show the machining processes (or any procedure) making it a LOT more interesting to watch. Especially since I find trying to properly illuminate a work area causes me lots of grief, even without trying to make videos! My kingdom for the Perfect Worklight! BTW I think it's so great that people choose to repair (and upgrade) lawnmowers and similar rather than simply throw them away!

I thought as you did, that's got to be easy to make. I can advise that their price is equivalent to approx 190 USD!!!... So thank you so much for a great video and saving many of us a lot of money. 😊

    Thanks Dale. For those that might be interested this mower is 52 years old (owned by me) and had the original seals still in it top and bottom and it still ran and started great. Bottom of crank close to blade (side play) had far exceeded original specs and was super sloppy. piston and cylinder spec out like new still with no wear what so ever. don't even have to use my new. piston that I acquired about 20 years ago Ring end gap was close to 0.040 if you can believe that and it still had decent compression.. Steady died of 2 stroke lawn boy oil is all this machine has ever seen. Again thank you for helping me out here. Charlie

    This will help for 1-2 years, but the real problem is the seals leaking after time. As an ex dealer in lawnboy we tried double lipped seals and even stacking 2 seals in the case. It all helps, but the seals will eventually fail. Keep up the good work !

    • @montana2strokeracer
      @montana2strokeracer 18 годин тому

      Hey Dennis, I did this retrofit to mine personal mower over 10 years ago. Use it every season and have not put a seal in it since. Starts easy and runs great. Not to say it can't happen, just hasn't happened to me. I have tried the double stack seals and lipped seals too, and your right once the bushing is walered out the seal will never hold. But this prevents the crank from moving excessively. Just my experience.

    @rcf8367 22 години тому

    Great video, I watched all clips in your LB playlist. You make it look so easy. My old C series “long snout” cases were not round OD bushings, looked they poured the brass in, then bored it out to fit. I have 3 from the 70’s that I use weekly & a couple of spare cases. No local machinists would tackle the conversion. Had the INA made SCE1412 bearings & seals already…

    • @montana2strokeracer
      @montana2strokeracer 18 годин тому

      I think your right RC, I think the bronze was poured when they cast the cases. It's not real uniform. I am not surprised about the machine shop; I have a lot of folks tell me they don't bore motorcycle cylinders either if they are over 10 years old. I guess it's a liability thing. Sometimes I worry about it too, when I get a cylinder sent to me and it is insured for 1000.00 bucks. Makes me think twice before I bore it. Everyone messes up from time to time. I have done several of these lower end conversions and they work great. The one I did on my own mower has been running for over 10 years now, and I have not had to put another seal in it.
