Auger Gear Box Oil; Adjusting Auger/Impeller Drive Belt - Toro 38542 Operator's Manual

annually. If possible, run engine just before changing
oil because warm oil flows better and carries more
contaminants than cold oil.
1. Pull wire off spark plug and make sure wire does
not contact plug accidentally.
2. Clean area around oil drain cap. Next, slide oil
drain pan below drain extension; then remove oil
drain cap (Fig. 23).
3. After all oil is drained, reinstall oil drain cap
securely.
4. Position snowthrower on a level surface. Next,
fill crankcase with oil: see Fill Crankcase With
Oil, page 10. Wipe up any oil that may have
spilled.

Auger Gear Box Oil

The auger gear box oil level must be checked at
setup, after every 10 hours of use, and upon removal
from annual storage. To check the auger gear box oil
level:
1. Position snowthrower on a level surface.
2. Clean area around pipe plug so dirt is removed.
3. Remove pipe plug from gear box (Fig. 11).
4. Check level of oil in gear box. Oil must be at
point of overflowing in filler opening.
5. If level of oil is low, add GL–5 or GL–6 SAE
85–95 EP transmission oil to the gear box until
point of overflow.
6. Reinstall pipe plug in gear box.
Adjusting Auger/Impeller Drive
Belt
If auger/impeller belt slips, resulting in decreased
snowthrowing performance, an adjustment is
required. WHENEVER A NEW BELT IS
INSTALLED, AN ADJUSTMENT IS
REQUIRED. USE ONLY GENUINE TORO
REPLACEMENT PARTS.
1. Pull wire off spark plug and make sure wire does
not contact plug accidentally.
2. Remove (3) flange head capscrews securing belt
cover to engine frame and slide belt cover up
cables (Fig. 4).
3. CHECKING IMPELLER CABLE
ADJUSTMENT—Depress the auger/impeller
control lever on the right hand grip. Hold the
lever and insert a .010" (.25 mm) feeler gauge
between a coil in the center of the spring
(Fig. 24). Adjust the cable to achieve .010" (.25
mm) gap between the coils.
4. Loosen upper jam nut securing auger/impeller
cable to mounting bracket (Fig. 25).
5. Rotate bottom jam nut upward to increase belt
tension.
6. Tighten upper jam nut against bracket.
7. Recheck idler adjustment: refer to step 3
8. Check impeller brake arm clearance by releasing
the auger/impeller lever. With the lever released,
there should be more than 1/8" clearance
between tab on impeller idler arm and brake arm
(Fig. 26). If there is less than 1/8" clearance,
belt must be replaced.
