18. Auger housings 26", 28" and 30" cracking in each front corner at the bottom.
a. If the cracking is only less than 1" then you can install support brackets part no. 705-5238 and 705-
5239. If the cracking is more serious then the housing must be replaced.
NOTE: Beginning in 1995 the shave plate was changed. It now wraps up at each corner firmly securing the
auger housing.
19. Auger welds failing prematurely. This is generally caused by excessive loads or sudden impacts with ice
chunks or other hard pieces of debris.
a. The affected auger must be removed and re-welded and painted. If the flytes or spokes have been
damaged then the component must be replaced.
20. Premature failure of the auger gear box keys part no. 714-0388 (1992 through 1995) and 714-0161 (1995
through 1996).
NOTE: Failure of these keys is generally related to severe usage and impacts with hard debris or ice
chunks.
a. Replace broken key with new key part no. 714-0161.
CAUTION:Service dealer must take a close look at the condition of the augers and the fan assembly to
determine if the unit has been subject to severe use and possible ingestion of rocks or large
ice chunks.
21. Impeller fan paddles bending on part nos. 784-5187 (1992) and 784-5187A (1993 through 1996).
NOTE: This condition is generally related to severe usage or the ingestion of gravel into the fan area.
a. Replace component with new fan part no. 784-5187A.
NOTE: Service dealer must take a close look at the condition of the augers and the fan assembly to deter-
mine if the unit has been subject to severe use and possible ingestion of rocks or large ice chunks.
22. Frame assembly part no. 684-0030 (1992 through 1996) cracking around the engine mounting bolts and
also at the front left and right sides where the auger housing fastens to the frame.
a. Replace the component with part no. 684-0030. This component has undergone a series of changes.
The most recent changes are as follow: 1) The material composition has changed. 2) There has been
additional embossing added to the top of the frame. If you view the frame from the top you will see (3)
long embosses running from the front to the rear of the frame and an additional emboss at the rear of
the frame that joins the (3) long embosses together. This looks like the letter E. Finally there are (2)
additional circular embosses around the front two engine mounting holes.
NOTE: If the snow thrower is a 1992 model experiencing repeated cracking make sure the service dealer is
aware that Tecumseh Products Co. made a significant change to the crankshafts in both HM80 and
HM100 engines. They have added material to the counterweights to improve the harmonic balance
on these engines. The balance of the connecting rod and crankshaft are now equalized reducing
overall engine vibration. This information can be found in the 1992/1993 Tecumseh Technicians
Seminar Handbook on page 12.
