Moodymike Posted January 20, 2021 Posted January 20, 2021 When dummy engine crankshaft turned all six axles turn, when driven under motor only the four rear axles turn, no drive to crankcase or front axles. Help please. Quote

As I said few days ago this set really deserves its own dedicated topic dealing with h issues, problems etc, but here it sounds as builder forgot to put gear in differential or 12 tooth double bevel gear that works with front differential..

Help please. You should be careful about your wording. This set has three axles with a total amount of six wheels. There is a central differential installed at step 95 (click the link), which distributes the power from the motor to the two rear axles and the front axle. Inside that differential there are 3 three smaller gears. Based on what you describe I would assume that not all of them are installed. To be more specific, I think your are missing the gear installed at step 95 nd substep 3. So please start checking from steps 95 on, if everything is assembled correctly. And please carefully follow the instructions. Take your time and double check everything. If all the gear are installed, please put the truck on its back so the wheels are at the top. Then try to block the two rear axles, while you are driving. Does the front axle now turn? If yes, there seems to be an issue with to much friction on the axles and gears, which are driving the front wheels. So make sure you don't assemble gears and axles too tight. I wonder why Lego doesn't include this advice anymore: Edited January 21, 2021 by Andman added link and more info for troubleshooting Quote
