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

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).

1

Figure 1

DSC-0168

1. Check/fill plug

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) (Figure 2).

 

 

Figure 2

MVC-458

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.

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.

Primary Method — Minimum Disassembly

The following steps apply to all models.

1.Remove the belt cover. Loosen the belt guide on the engine crankshaft and remove the auger belt. DO NOT bend the belt guide out of the way (Figure 3).

 

 

Figure 3

MVC-526

2.On the forward side of the auger pulley is 1 or 2 set screws, depending on the model, which must be loosened. Use the square end of a 3/8” socket extention. Note: The pulley is keyed to the shaft and will be removed later (Figure 4).

 

 

 

Figure 4

MVC-527/MVC-536

3.In the center of each side plate are either two or four cap screws (depending on the model). These go into the bearing that supports each side of the auger. Remove the cap screws (Figure 5).

6.Begin to pull the auger assembly out to the front. Note: The auger pulley and key have not yet been removed. However, if you pull the auger slightly forward, it will make it easier to slide the pulley off the end of the impeller shaft. Once the pulley is out of the way, remove the key (Figure 8 and Figure 9).

The auger assembly can be separated from the traction assembly. However, it is generally not necessary to work on the auger. Should the auger pulley be rusted on the shaft, it might be easier to remove the pulley with the traction assembly out of the way.

Secondary Method — Traction and Auger Housings Separated: Toro Models 38065 and 38080

1.Remove the belt cover. Loosen the belt guide and remove the auger belt (Figure 12).

INSTALLATION

Installation of the auger assembly into the auger housing can be done whether the auger housing and traction assemblies are connected or not. There is no significant time savings to either sequence.

1.All self-aligning bearings (sometimes called the flange bearings) MUST be installed loosely. All models have one next to the auger drive pulley and some use 2 more supporting the auger output shafts. In all cases, these bearings must be a little loose to assure the bearing can align itself with the shaft before it is secured (Figure 19).

Figure 19

MVC-540

1. Bearing and flange

2.Make sure all the parts are installed on the auger assembly. All spacers, thrust washers, and auger bearings need to be hanging on the shafts.

(Including the scraper for models 38065 and 38080.)

3.Slide the assembly into the housing, directing the input shaft into the rear bearing.

4.Start the cap screws from the side plates into the bearings that support the auger output shafts. Some models have 2 cap screws into a fixed bearing; others have 4 cap screws into a selfaligning bearing.

5.Models using four bolt bearings ONLY - Strike the side plate and bearing area with a rubber mallet three or four times, then secure the bearings. The jolt aligns the bearings (Figure 20).

 

 

 

Figure 20

MVC-542

 

6.All models — Rotate the impeller back and forth. One direction will push the impeller shaft to the rear. Rotate it in that direction to force the shaft as far to the rear as possible (Figure 21).

7.Secure the 4 cap screws on the self-aligning bearing. Install the thrust washer and key.

8.Holding the shaft to the rear, install the pulley on the shaft. Push the pulley forward, hold and secure. The pulley is used to limit the front to back movement of the impeller (Figure 21).

AUGER GEARBOX DISASSEMBLY / SERVICE

Once the auger gearbox assembly is removed from the housing the repair process is the same for all models. The only variables are what type of lubricant is used (see the chart on Introduction page 1), whether the impeller is removable from the shaft (on some models the impeller is welded to the shaft) and how the gearbox case halves are sealed.

Auger gearbox disassembly:

1.With the gearbox assembly removed from the housing the first step is to slide the bearings off the output shafts. (Model 38080 & 38065, also slide the scraper off).

2.All models use a cap screw, lock nut, and spacer to connect the auger to the shaft (Figure 22). Remove the cap screw, nut and spacer and slide both augers from the shaft.

 

 

 

Figure 22

MVC-533

3.Some models have the impeller welded to the impeller shaft. Others use a combination of bolts, set screws, and a key. If you see bolt(s) through the impeller hub, remove them. Some may have set screws, which only require being loosened. The models with the setscrews also have a key between the hub and shaft. Once the visible retainers are removed, slide the impeller away from the gearbox, the key will be uncovered. Remove the key (Figure 23).

 

 

 

Figure 23

2773-055/2773-066

4.Remove the 8 or 9 self-tapping screws that hold the gearbox halves together. Note: On a model that uses 90 weight gear oil, you may want to place the gearbox over a pan when the screws are removed. Then separate the gearbox halves (Figure 24).

 

 

Figure 24

2773-060

5.The impeller shaft can now be removed (Figure 25).

6.Clean the output shaft and slide the case halves off. Remove the seals from the case halves and discard the seals.

7.Clean and inspect the bushings in the case halves. If they are damaged or worn, press them out of the case halves at this time.

8.Slide the worm gear off the shaft. Depending on the model, there will be one or two woodruff keys between the gear and the shaft. Refer to the parts manual for your specific machine.

9.Returning to the impeller shaft, the 824XL models have a worm that is actually rolled into the impeller shaft. All other models use an individually replaceable gear. Remove all the bushings, bearings and spacers from the impeller shaft (Figure 26).

10.Now inspect the worm and worm gear. If either gear is damaged, replace them both. When gears run together, they develop wear patterns unique to the two of them. Replacing only one gear will result in early failure.

Failure Analysis

There are some misconceptions regarding these gearboxes that result in incorrectly identifying the causes of failure.

The square cut ring on the impeller shaft is not really a seal. It is a wiper ring that has a tendency to pull down to the shaft when the shaft begins to turn. The bushing next to the ring really deflects most of the oil that is thrown towards that area. The loose fit provides a vent for the case (Figure 27). Occasionally a drop or two of oil will get between the bushing and ring. When the auger drive is disengaged, the ring will relax and that oil might drip into the auger housing. At this rate, the machine can be used for several years without any significant oil loss. The yearly oil level check is more than adequate to compensate for this.

If there is a significant amount of oil coming out of this area, it would indicate that the gearbox has been at a severe operating angle or the bushing is badly worn.

Oil on the bottom of the gearbox can result from a leak at any part of the case. As there is no internal pressure, any leaking oil runs down the side of the case and collects on the bottom until there is enough to drip off. The source of the oil leak oil can be difficult to see. Sprinkling some powder on the outside of the gearbox will usually show the oil trail. The type of powder used is not important. Just something that will stick to the oil.

When you open a gearbox that has had the gears fail, the remaining oil will likely appear as a small puddle of very thick grease in the bottom. Worm gears normally create a large amount of friction due to the sliding action. When something goes wrong, not enough oil, poor quality oil, a problem with the gears, or just a gear or bearing wearing out, the friction becomes abnormally high. The remaining oil is cooked down to a very thick residue. This can be the result of failures, not the cause.

GEARBOX ASSEMBLY

1.Use a wire brush or sandpaper to clean the auger shaft. A clean, smooth shaft will help avoid damage when installing new bushings and seals. Clean the old gasket material from the case mating surfaces (Figure 28).

2.If new bushings are to be installed in the gear case halves, now is the time. Apply a thin coat of Loctite™ Blue #242 or equivalent to the OUTSIDE of the bushing and press in flush with the INSIDE of the case (Figure 29). This will allow space for the seal on the outside. Wipe up any Loctite™ that is visible. The Loctite™ must not get into the gear or seal area.
