This new TH400 rebuild kit comes with everything needed for your standard High Performace clutch and steel refresh for your TH400 with Alto Red Eagle clutches and Kolene Steels.
Alto Red Eagle® material offers similar mid-point coefficient at high horsepower applications. In addition, the Alto Red Eagle® material gives superior friction wear characteristics at high energy engagements. The leading competitor's material degrades thermally and physically after reaching approximately 2.25 HP/in2.
Below we offer some engineering data collected with this particular clutch.
Six Level High Energy Test
On Frictional Properties And Wear
Lbs./Sq. Inch Pressure Required To Stop Flywheel In One Second
| Levels | Cycles | OEM Manufacturer A Pressure Required (Lbs./Sq.In.) | OEM Manufacturer B Pressure Required (Lbs./Sq.In.) | ALTO Red Eagle Pressure Required (Lbs./Sq. In.) |
|---|---|---|---|---|
| 1 | 10 | 64 | 70 | 66 |
| 1 | 100 | 65 | 71 | 65 |
| 2 | 10 | 72 | 84 | 74 |
| 2 | 100 | 73 | 84 | 74 |
| 3 | 10 | 85 | 96 | 86 |

| 6 | 10 | 136 | 148 | 131 |
| 6 | 100 | 143 | 152 | 134 |
NOTE: The Lower Lbs./Sq.In. Required to stop the flywheel, the higher the frictional properties.
Results: Pressure required to stop the flywheel on "ALTO RED EAGLE" are slightly lower than "Manufacturer A" and well below "Manufacturer B."
Conclusion: The frictional properties of "ALTO RED EAGLE" are slightly higher than "Manufacturer A" and well above "Manufacturer B."
