MQ SP2 SLAB SAW — PARTS & OPERATION MANUAL — REV. #7 (09/08/06) — PAGE 33
General Transmission Care (Self-Propelled Models only)
All SP2 model saws utilize spline gear wheel design coupled
with an EATON Model 7 Hydrostatic Transmission that provides
forward/reverse propulsion. The simple design of the system
keeps maintenance to a minimum.
Transmission Reservoir Cup:
Check every 8 hours of operation. When the transmission
is
cold
(A), check oil level against the level indicator (see
Figure 45).
Servicing:
The transmission reservoir is factory filled. Should servicing
be required, use SAE20W-20, API classification (SE,CC,CD)
or better, General Motors Dexron B, Ford M2C-33F, M2C-
41A or International Harvester Hy-Tran fluids. For extreme
hot weather
, drain oil and refill with an oil having a viscosity
of SAE30W-30 or SAE40W-40.
Drive Chain:
Check every 50 hours. Periodically wipe the chain clean and
re-lubricate with penetrating chain oil.
The drive chain may stretch requiring tension adjustments.
To adjust the drive chain tension:
1. Loosen the (3) transmission attachment screws (Hydrostatic.
Transmission Assy., item 2)
2. Pivot the transmission in the
“U” slots
of the
transmission
mount
until the proper tension is achieved (Hydrostatic
Transmission Assy., item 7).

Spline Gear Wheels:
Check every 25 hours and clean as necessary. If the spline
wheels DO NOT engage the
rear
wheels
with sufficient
pressure, slippage of the rear wheels may occur.
To adjust the
Spline Gear Assembly
:
1. Place the
transmission engage/disengage lever
in the
DISENGAGE position (Figure 46) .
3. Loosen the linkage adjustment nut and slightly lengthen the
linkage rod (see Transmission Engage Lever Assy., items 11
and 13).
4. Move the
transmission engage/disengage lever
to the
ENGAGE position to observe the proper spline-to-rear wheel
contact.
5. Retighten the adjustment nut.

CAUTION
DO NOT use multiple viscosity oils! DO NOT OVERFILL.
NOTE
Excessive tension on the drive chain
will reduce chain life.
