Servicing the Transmission
The transmission should also be cleaned and serviced periodically. All gears and shafts should be closely
inspected for wear and replaced if necessary. Always use a high-quality grease or lubricant like LOSA99203 to
prevent premature wear and/or failure.
Removing the Transmission
1. Remove the gear cover.
2. Remove the throttle and brake linkage as well as the fwd/rev linkage.
3. Loosen the four motor mount screws (bottom of the chassis) and slide the
motor back.
4. Remove 2-speed spur gears.
5. Remove the five transmission mounting screws and lift the transmission out.
6. Remove the outdrive and ten 5/64” cap head screws. Remove the transmission
case half.
7. Regrease the gears and shafts, inspecting each for wear.
8. Replace any worn or failed gears.
9. Wipe out the inside of the gear case, removing any debris, old grease and
foreign matter.
10. Check all ball bearings for free movement cleaning or replacing as necessary.
11. Reinstall gears on the shafts lubing with LOSA3066 or LOSA99203 Losi Assembly Grease.
12. Reassemble the transmission lubricating liberally with LOSA3066 or similar high-grade grease.
13. Make sure the setscrews in the outdrive cups are tightened (a locking compound is highly suggested).
14. Install the transmission in the chassis; reset the gear mesh by using a small piece of paper between the
pinion and spur gears, applying pressure while retightening the engine. Reconnect all linkages and
connetions as necessary.
