Busa/VW091 Adapter Testing Results

Where did you find the torque ratings. A 760 uses them and weighs 5026 empty with 550FTLB's of torque. With a first gear of 4.71-1 they should be good for at least 2600FLTB's of torque.............
 
Even the lowly 3 series with 200FTLB's and a 4.32-1 should be good for 900..........

Are you SURE the ratios stated are first gear? Aren't they rear end ratios?

Duratron?

wait - just found it on sale - meldin 7021 - perfect for what you want?  $21,000.00 - maybe a bit pricey.

Why can't you use PTFE and machine out the coupler? 

Seems like it has all the qualities you want and is inexpensive?

You say there were no signs of rubbing on the inside of the housing. It would seem to me that once there was chunks flying around, they would rub. I wonder if it does not look like there was rubbing in one spot because everything was rubbed by all the broken pieces. Maybe spray some paint on the inside of the housing before the next trial.

Kinda deep in know, but they are using a fairly low rear end gear.

BDKW,I went back to my notes and see where I assumed a higher low gear ratio of approx 3:1 and saw that the tq ratings were similar to what the LJ should handle with a green spider. Problem was that all I found at the time referenced to large Guiblo and it is too large to fit in. I didn't know about the smaller one . It appears that it could well do the job. Boost,what are the dimensions od the small one? I need it to be no more than 80MM OD.

It will be very close, if not a hair too big for what you want.  I can't find my drawing for the mounting flanges.  I sold the skid loader to a customer.  If I talk to him this weekend I will get actual measurements.

Thanks for any help you can give. I can probably arrange something to allow about a 4.5" OD  now that I look at it. If my research is correct the small guibo is 4.33".Would have to do away with the torque tube but with a guibo that's not an issue. As bdkw pointed out the small guibo would likely be a good match to this application if it will fit. Only possible drawback would be the reports of the guibos not being as reliable as I'd like but they would be very easy to replace if needed.

I found the drawing and a pic on my other computer.  Looks like the flanges I made were 4.33" OD.  here is a pic of the coupler I made.  It works fine for my application, but you might want to do something more substantial for the pins.  I just used bolts through the metal bushings.  For yours I think I would press out the bushings and make pins to fit that were pressed and welded into the flanges.

[fabr]

Cool,that's what i was hoping.   Approx what is overall thickness of the assembly?

[Boostinjdm]

If I remember right, the guibo itself is only like 1-1/8" or 1-1/4" thick.  My flanges were 3/8" thick. Including the hubs sticking out both sides It might be 4" or 5" long.

[fabr]

About  what i was thinking. Thanks for the help.

Had an engineer suggest using titanium for the spider.

Had an engineer suggest using titanium for the spider.

Just weld the two halves together.....

Now you have had an engineer suggest that to....
