Form FUL-169
Approved Applications For Fuller Twin Countershaft Mechanical and “Top-2” Transmissions
Written Approval Required For All Applications Not Meeting the Requirements of This Form - Use Form FUL-
170 (Request for Application Approval).
All approvals are based on the following conditions:
• Lubricants must meet the requirements published in Eaton TCMT-0021.
• Driveline speed not to exceed 3000 RPM except — RT-6609 -4000 RPM.
• Angular acceleration of driveline is not to exceed 300 rad/s
2
.
• High Angle lubrication kit required when installation angle plus operating grade angle exceeds 12
degrees (20%).
• Vehicle must have sufficient overall reduction to insure Startability (See Startability Attachment — FUL-171).
• PTO torque limit - Maximum combined PTO output torque is not to exceed 500 lbs-ft for Lightning, FR/FRO and Convertible series transmissions.
• The maximum allowable torque at the transmission input shaft, due to engine retarding systems and engine friction, must be less than 110% of
maximum transmission torque rating.
• Transmission input torque spikes due to drive train resonance, must be less than 300 lbs-ft above the nominal transmission input torque
rating for engine speeds above 1000 RPM and vehicle road spee d above 20 MPH.

NOTE 3 — Transmission Oil Coolers are:
Recommended — With engines of 350 H.P. and above.
Required — With engines 400 H.P. and above, and
GCW ’s over 90,000 lbs.
— With engines 400 H.P. and above and
1400 lbs-ft or greater torque
— With engines 450 H.P. and above
— With engines 1500 lbs
-ft and above
In all cases, cooler must have sufficient capacity to maintain
oil temperatures below 250°F at worst case operating
conditions.
Additional Application Requirements for Approval of RTLOC-1X909A-T2:
• Application must be for On-Highway use only.
• For engines certified by Eaton for use with Top 2 transmissions, see Form FUL-200T.
• Vehicle must have a minimum of 0.3% gradeability at cruise speed and 1% gradeability at peak torque. Calculations are to be made at
maximum rated conditions.
• Vehicles using Detroit Diesel S60 engines must have rear axle ratio higher than 3.70 and tires with 492 revs/mile or greater.
• Any Progressive Shift engine programming must allow automatic up-shift points to be reached – minimum 1500 RPM.
• Vehicle must have a 12-volt electrical system.
• Vehicle air system must include an air dryer.
On-Highway is defined as limited access and general highways. Grades less than 8%, well maintained, concrete or asphalt surface, no more than 10% off-
highway operation. Maintained gravel, crushed rock, hard packed dirt or similar road surfaces are acceptable when grades are less than 3%.
Blanket GCW limit is just a limit for Blanket approved applications. Applications that exceed this limit need to be submitted to Eaton Corporation for approval.

• Vehicle configurations that exceed the 3000 RPM driveline speed can be blanket approved IF the engine is electronically programmed to limit
the vehicle speed that produces a driveline speed of 3000 RPM or less in top (overdrive) gear.
• Vehicles using Caterpillar C11, C13 or C15 engines must have a rear axle ratio higher than 3.55 and tires with 492 revs/mile or greater.
NOTE 2 — "A" calculation for Auxiliaries
All other transmissions are limited to a maximum of 350 lbs-ft with the standard input shaft bearing (P/N 82504). IF the input shaft bearing is
upgraded (P/N 4301417), the PTO output torque is not to exceed 500 lbs-ft. The RT-6609 is limited to 300 lbs-ft.
