  • OK, fair to say this thing was built too lightly in the first place - add more steel! 😁
  • Man I tell ya. Transmissions are far beyond my paygrade. I am just not good enough. So great job man.
  • Nicely done. I had to repair a gearbox that was used at Heathrow Airport which was used to jack up the nose wheel on 747s so the tyres could be changed. That box had lost all it's oil and was not checked until it seized. The TIG welding on the bearing diameter was a good move. 👍

    As best you could?! I think you built it better than it was factory! Cool unit, the way they made that frame definitely leaves a lot to be desired.
  • Another great addition to the series Donn and brilliant repair and rebuilding up the bearing Cup as welding on alloy cast is inherently difficult with oil contamination. Keep up the great work

    Great work me son !! My 6x and my buddies 8x pretty much had almost every weld cracked,along with cracking in solid flat areas also,every single stub shafts bearing was toast,every sprocket,every link of every chain,zero brakes remaining,tubs had multiple cracks,both engines smoked,tires were mix n match and mostly half would be flat the following day after airing them up even though they had very little tread left,were dry cracked all over,1 of mine was even splitting along the 2 casings joint.. Marks 8x was in much better shape than my 6x but his cost him 25% more for us to rebuild than mine did and neither of them were cheap to do a full off rebuild like you've done here and yes every single gearbox I've ever seen or worked on was thrashed like yours was... People literally believe these things are military grade tanks when, in fact, they're fairly light duty machines that actually do require a fair amount of maintenance and effort by their owners/operators.. I bought my 6x for $800 USD cash many moons ago and had not quite a new Argos cost in it when I finished,but it wasn't a while lot less,and Marks was the same way... Luckily a lot of these parts are now internet sourcible and readily available and cheaper than they were back then when one had to order out of a catalog,send in full payment,wait several long weeks for parts to be shipped,and then up to a couple of weeks for them to arrive... You're doing wonderfully Donn,keep up the excellent effort, and I'll sit back with a frosty adult beverage n relax while you do all the sweating and hard work 😅

    Am amazing that this Argo stayed together as long as it did considering all the structural damage that you have repaired in this rebuild. It must have been beat like a red-headed step child from day one.
  • Gearbox rebuild looks good to me should last a long time keep it up
  • @rjung_ch
    That is looking really way better than what you started out with. The oil changes and the magnet in the drain plug will be a good addition for sure. 👍💪✌
