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

[mfenmor]

I will be there JB.

Spent another day in the garage working on the last frame mods.
I call it the Keith mod, (onlyonce).

First... warm up the cold bits.

Not bad for 35 outside and no insulation.
I was working in a T-shirt and pajama pants.

Next...remove the flimsy bits.

Use the discarded flimsy bits as a template to locate holes on the Hefty parts.
This will be required with the turbo Kubota.

Clamp hefty parts onto the frame, make sure holes line up nicely.

Then, weld weld weld.

And weld some more.

Tomorrow will mock up trans mount braces and motor mount.

Looking real good. You will not be disappointed in either how well it works holding things in place or how easy it is to remove and adjust.

Thanks Keith.
Glad I was able to use your good idea before putting the frame back in.

mike ... a few thoughts on the design . so the portal boxes will bolt thru the tub into the outer frame rails , right ? so you must be thinking those rails need beefed up support to keep from bending from the stress of the weight and because the wheels and tires will be offset of the rails . maybe once they are on , a removable x brace under the tub connecting the front and rear boxes . also i think is was discussed to have removable tie rods connecting the boxes from front to back , so if the front tires hit a log first , all boxes will take the load. if they are tied together to the portals with tabs and bolts , then if one box needs repair it's easy to remove the tie rod and that one box. just a few thoughts and i'm sure you already have the designs thought out . it will be one cool design . j.b.

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.

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.

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.

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.

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.

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.
