Hello guys, Gsx owners know well how all wheel dynos are not as common and neither is access to lathes. So that’s how I ended up with this idea since I had a couple of viscous couplers laying around from transmissions my GSX had murdered over time.
Tools Required:
1. angle grinder with 6 inch cut off wheel
2. 4.5 inch flap disc. Or angle air die grinder.
3. I used a Lincoln 140hd mig welder to weld it.
4. Brake cleaner
5. Air blower
6. gloves
7. Safety glasses
8. Long sleeved shirt or leather welders sleeves like I got due to all the sparks flying everywhere burn arm.
9. Fan. It kinda stinks when cutting. Good idea to have a have a fan to direct the fumes to whichever direction you want smell blowing.
HOW TO:
Begin with cleaning viscous coupler thoroughly with brake cleaner and blow with compressed air using blower to dry it so won’t stink or catch fire while cutting.
Place the viscous coupler on a vice then sink cuts into it carefully with angle grinder as pictured. (At time I did it didn’t have a vice did it all on floor)
You may need to cut from both sides since the angle grinder wheel may not go through all the way due to depth.
It’s a lot of cutting if have one angle grinder give it 15 mines of cool down time after ever 15 minutes of use. That’s why I use two. Especially if own a harbor freight one you may experience premature failure of the tool. They can’t take it. Ask me how I know
.
Once cut all the way through in hex shape, use the flap disc to smoothen all around as seen in pictures. Brake clean it some more and use a compressed air to blow it out again more in preparation for welding.
Weld the unit as seen on the installed on car towards the side facing outward of transmission (see picture) button up everything remove transfer case & driveshaft and car is ready to go onto a 2wd dyno.
That’s how I did mine. I’m sure a lathe is the ideal way to do it but we all don’t have easy access to one. Hopefully saved someone some money and need to travel far for an awd dyno.
