B-FAST R/C PERFORMANCE

Differential Break-In Procedure

1) Clean all parts and work area

2) Follow owner’s manual for assembly instructions

3) Lightly Coat Diff Balls with B-Fast Pro Diff lube, thoroughly lube Thrust Bearing with
B-Fast Pro Thrust grease. (or equivalent)

4) Snug diff screw just until gear will not turn while outdrives are held.

5) Hold one outdrive from spinning, a hex wrench that fits into the outdrive slot, clamped to your bench or in a vise works good.

6) Use a power drill or Dremel (the cone shaped cotton polishing tip works great) to spin the diff for about 20 seconds (HIGH rpm on drill, LOW on Dremel). Reverse rotation for another 20 seconds.

7) Tighten diff screw about 1/16 of a turn and repeat step 6

8) Repeat step 7 at least two more times.

Follow owner’s manual to set slipper

Slipper should slip BEFORE the diff

Do Not let the Diff Slip at anytime!!
