The adapters are made of
cast iron, not aluminum or
steel like wheels. They are
not designed to withstand
the use of impact tools.
DO NOT USE IMPACT
GUNS TO ATTACH THESE
ADAPTERS! 20-30 ft. lbs.
/ 30-40 N-m applied by
hand is plenty to secure
the adapter to the vehicle.
Excess torque applied
with an impact wrench
will damage the adapters.
Warranty does not cover
this misuse.
WARNING
STEP 1: MOUNT THE ADAPTER (2 Minutes)
MACHINING ROTORS
In just 4 steps in about 7-9 minutes, any tech can perform top-quality brake work.
Step 1: Mount the Adapter (2 mins.)
Step 2: Set up the Lathe (1-2 mins.)
Step 3: Adjust for Lateral Run-out (1 mins.)
Step 4: Make the Cut (3-4 mins.)
The First step is to choose the proper adapter. Most passenger cars require either the four (50-687) or
five lug (50-688) Direct Fit® adapter. Some larger passenger cars and smaller trucks use the (50-695)
adapter. For most trucks and vans, use the larger adapter (50-691) or the Asian / European variant, the
50-681. This fits 5, 6, 7, and 8-lug vehicles. See the adapter guide on pages 72-73 of this manual, or
use the adapter search on the Pro-Cut website for more specific information.
Once you’ve selected the correct size adapter, try each bolt pattern until you find the one that fits the ve-
hicle evenly. When possible, use the nuts provided with the machine. Hand tighten nuts with an open
box end wrench or a torque wrench in a star pattern. Do not use impact wrenches to mount adapters.
Nuts should be hand-tightened to 25-30 ft. lbs. / 30-40 N-m. Excess torque may damage the adapter.
Some vehicles require the use of a spacer (30-791 or 50-246) which are provided in the lathe package.
If the adapter doesn’t fit flush and square, use the spacer. Sometimes the holes in the spacer are not
needed as the entire bolt pattern will fit in the center of the spacer.
If the four steps are followed properly on each brake job, the Pro-Cut 9.0 DRO RMS will operate accurately and efficiently.
