BELT
The GP-6 Cabmaker arbor is driven from the electric motor by a AX-24 rubber belt. The belt tension
is adjusted at the factory. However, if it is necessary to service this belt, unplug the GP-6 Cabmaker
from its power source and remove the fasteners that secure the belt guard housing to the motor. The
belt tension should be checked periodically by removing the guard and depressing the belt in the
middle between both the motor and blade arbor 2" OD pulleys. There should be 1/2" of deflection
when the belt is pushed down (Fig 43). If the belt tension should become loose, poor performance or
slipping will result. If the belt is too tight (i.e. no deflection) the belt, electric motor, pulleys and blade
arbor bearings may wear out prematurely or the motor may overheat and shut off. Belt tension can be
adjusted by loosening the two mounting bolts attached to the base of the motor mount and sliding the
motor cradle base forward or backward to increase or decrease belt tension. Be sure to adequately
retighten the motor mount nuts and replace and attach the belt guard to the table as well.
ARBOR ASSEMBLY
The GP-6 Cabmaker is equipped with a 5/8" OD arbor shaft, two rubber sealed ball bearings and a
2" OD x 5/8" bore die cast zinc coated pulley. Should the bearings wear out on the arbor shaft, grind-
ing and polishing performance and short diamond wheel/belt life may result. Additionally, premature
bearing wear may result in permanent damage to the arbor shaft, bearings, belt and motor. This main
stainless steel shaft arbor assembly can be purchased from Barranca Diamond as a complete unit.
Periodically check the tightness of the hood attachment knobs (Fig 44) to make sure they are secure-
ly tightened to the aluminum body of the GP-6 Cabmaker. Should the 2" OD die cast pulleys on either
the motor (Fig 45) or wheel arbor shaft need to be removed or replaced, loosen the setscrew on the
hub of each pulley with a US standard Allen type wrench. The setscrews can be secured with liquid
thread locker (removable type) to prevent loosening due to vibration.

ELECTRIC MOTOR
The GP-6 Cabmaker is equipped with a Baldor 1/3 HP 1725 RPM single-phase 120 volt 60 Hz 8 amp
motor. The motor shaft has sealed ball bearings and requires no lubrication. The motor is protected
from thermal damage (overheating) with an automatic shut-off switch. If the motor overheats it will
automatically shut off and restart once its internal components cool down and the motor is restarted
