Guy goes into a garage to grease bearings.....

I got a little more room in the garage today...
Because frame is in the tub! WHOOHOO!

Let the assembly begin.
Had to trim the skid plates a bit. I only want one layer between box and frame.

But not for a few days. Gonna be busy plowing 2 feet of snow which has already started early.
Glad I got a Max Kubota WG750 with a snow plow ready to go.

amazing fabricating mike ...hope you don't mind me being totally engaged in your project . after designing and building kiddie rides for 15 years , i love the creativity of a build like your doing . my mind starts visualizing whats next and how will it be tackled. latest thing is thinking about your portal boxes and the sprockets and chains in them wondering what size chain , and how will they be able to be tightened if needed. i,m thinking of some kind of the hard plastic chain tensioner material inside the portal half way between the sprockets on one side of the chain that could be adjusted from the outside of the portal by a watertight bolt ... ? or something . maybe you have it figured out already .. and i'll go wow ! what a great idea . j.b.

Thanks JB.
I build kiddie rides too, just for bigger kids.

Got all the engine and trans mocked up.
tomorrow I'll paint and drop it into the tub.

slots to adjust the belt length.
I'll add jack screws to adjust the position.

lots of space between motor and trans.

Keiths trans hold down design with a twist.

Another cold day, but managed to get my butt in gear and go start the fire in the garage.
Outside thermometer said 15.
in the garage....

Way to cold today. I didn't even want to go out and start the fire.
No work today.
Tomorrows another day.

Lookin' good Mike!

so much fun mike..i was trying to figure out how in the world you were going to get the chain around the sprockets in the portal boxes and have room to get a master link link on. the i figured the only way was to connect the sprockets with the right length of chain , lower them in the boxes and then slip the axles thru . am i close?? j.b.

JB, You are right on the nose. I guarantee there will be some cussin.

Another long day in the garage.
Set up the motor mount and welded it together, then decided I didn't like it so chopped it apart and redid it.
No motor mount fails on this one. Lesson learned from the WG750 Max IV.
Motor can slide on mount to adjust for belt length.

looks awesome...i understand not wanting any '' undercarriage bracing'' that inhibits that unobstructed flow under the tub . i don't think the connectors front to back between the portals will be any obstruction cause they go with the flow of the machine. if you have to connect each set of portals ( the right one to the left one ) under the tub , some round pipe right under the tub closely would probably be a minimal obstruction for mud , rocks ,etc. thats the only thing with my max sub frame design is having to have some lower cross bracing to support the lower rails . but i used 1/2'' round rod for that and it has worked well with minimum drag. thats why maybe some angles on the front of the portals will add to your streamlining . i'm lovin your build , j.b.

Just finished the design for the motor mount which can be adjusted for belt length.
Had to do some research on drive belts to find a size that will work for me.
I started a new thread to help others as well; http://www.6x6world.com/forums/trans...ll-models.html

Tomorrow I can start building the motor mount without having a drive belt handy as now I know what size I will have.
Interwebs are a wonderful thing.

Got some more work done today mocking up transmission.
Started to make motor mounts as well.

Glad I had the WG750 done to use as reference so as to not have to put it in the tub and check clearances.

The D722 is from the same project, but I started it way back in 2015. Finally getting to see the light at the end of the tunnel.

Hey JB,
Yes, I did consider bracing external to the tub, both front to back and left to right, however I didn't want to compromise the extra ground clearance, other wise what's the point. I did extensive frame beefing (see pics). If this proves to be inadequate then some external bracing will be considered. I know that tire is a big lever hanging out there now. I will NOT be gentle with it.
Thanks for the input.
