VMG DIFF FIX | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
RACE IT DON'T BREAK IT!! Ok here I will show you how to fix the VMG diff once and for all! By Steve Carfi 9/1/03 |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Note: I will try to explain this as simple as possible! | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
This pic shows what plagues the VMG diff this is an almost new car! notice by red spot plastic rotating on plastic not lubed from factory fusing together NOT TOO GOOD, as you can see the white powder!! I will show you how to properly lube and assemble the axle later.. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
First you need to take the diff out of your car it will simply pull apart like shown in this picture. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
I used Parma homeset lube it works great.. But for all out performance i suggest cleaning out the diff and get all the grease that was in there out if there was any and use Team Associated Black Grease # 6588 This is used for there RC kits It is a very sticky grease and it will make your diff work much better than if lubed with silicone type grease.. But the Parma grease also works nice! |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Grease all gears as shown! ALSO add a drop of oil to each bevel gear where the tiny metal pin goes through them both! |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Very important!! You can substitute the grease and use a few drops of oil on this part if you wish.. But i like using grease here! Grease behind the bevel gear on the plastic shaft! To do this simply pull the diff casing away towards the tire as shown..Put a nice coat of lube on it!! DO THIS ON BOTH SIDES OF THE DIFF!! |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Very Important!! You can substitute the grease and use a few drops of oil on this part if you wish.. But i like using grease here also! Pull the bushing away from the diff case as far as possible as shown in the pic.. Now put a nice amount of grease here! DO THIS ON BOTH SIDES OF THE DIFF!! |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Now put like 2 drops of oil on the axle here making sure it drips down into the bushing! DO THIS ;ON BOTH SIDES OF THE DIFF!! |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Now clean your diff casing before the glue job! Clean your diff casing with a cleaner rubbing alcohol works fine here! make sure you clean all the way around the areas marked with the red dot! |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Here is the diff assembled correctly! (not glued together yet) |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
After you put the diff together properly go around the diffs seams on both sides where you snapped it back together with a light bead of CA glue (super glue) making sure to cover the seams.. I use a tooth pic to spread it smooth. this holds everything together and tight! |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Apply a generous amount of goop glue on bushings by using a pin trying to go all the way around all bushings on all the sides of the bushing where it snaps in place the 4 spots as shown this holds it all together tightly and stops flex..I use the goop glue because it can also be removed if needed.. LOOK AT PHOTOS BELOW! |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
DON'T BE AFRAID TO PUT THE GLUE ON!! as you can see i use a generous amount! be sure not to glue the bushing to the gear pumpkin |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Now before you put the chassis together apply a thin bead of goop glue as shown here below. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
PLEASE DO STEPS LISTED BELLOW THIS FIRST!! Make sure to go right across the edge of motor with the glue this will help stiffen her up! |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
A MUST DO!! Here i use grease and put it on all areas shown in red. Make sure to put a coat of grease right where the guide wires rub on the axle!! |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
The VMG magnet flop syndrome fix! Here i put a crumpled tiny piece of paper down into the magnet holder I put just enough so that when i push the magnet back in it just raises up a hair out of the holder this makes your magnet stay down where it needs to be ! IT WORKS GREAT! |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
KEEP IT OILED PROPERLY AND KEEP IT FAST! Oil by these spots marked above periodically by simply adding a few drops of oil to them. Oil the gears, the axle where it goes through the bushing and also in the side of bushing that hits up against the diff housing |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
NOW put the car back together oil the gears and let all the glue dry.. Now you will see your VMG FLY; like never before!! |
