Chapter 1 — Auger Gearbox Service
GENERAL INFORMATION
The manual takes a systems approach. There are two
versions of the auger gearbox and three versions of the
traction drive system used among the various 2-stage
models.
For information on the auger drive or linkage
adjustments see the section titled Belts, Controls and
Linkages.
The lubricant level in a gearbox should be checked
prior to each season.

AUGER GEARBOX LUBRICANT
Should you see an oil leak, disassembly is required.
Lubriplate MAG 1 is thick so it will normally not leak out
even with a failed seal. The bearings used in all
applications are oil impregnated, so they do not require
regular maintenance. Internal gearbox repair will
require removal from the chassis.
Two different lubricants are used in the various models.
They are NOT interchangeable. Use the lubricant
specified in the model chart.
90 wt. indicates a 90-weight gear oil. A multi weight
such as 85-120 is acceptable as long as it
encompasses the 90 weight. The oil used must also
have an extreme pressure (EP) rating of GL5 or higher.
Fill until it runs out of the fill check plug (Figure 1).
GEARBOX REMOVAL
There are two methods commonly used to remove the
auger gearbox:
•
The primary method is to remove the auger
assembly without separating the traction assembly
from the auger housing.
•
The secondary method is to separate the auger
and traction assemblies. Separating the auger and
traction assemblies improves access if the auger is
difficult to remove.

MAG 1 is a special low temperature grease made by
Lubriplate™. Use 1/3 tube of MAG 1 per gearbox.
Obtain from your area Lubriplate Distributor or from
your Toro parts supplier (Toro Part Number 505-101)
