WWR Truckpuller motor
click on photo to enlarge
my new 540 size Truckpuller motor run's by 7.2 volts with about 8000 rpm's
( 1/2 of the rpm's of a stock 540 Mabuchi motor , as used in most R/C kit's )
and has almost twice the torque as LRP's Truckpuller motor
this motor is perfect for any application where a slower overall speed is needed ,
without sacrifice of torque , but a gear-reduction can not be installed .
so fat I have installed this motor's in the following Tamiya vehicle categories :
Trucks, Tanks , 4 WD's like the Jeep Wrangler or Pajero ,
and even in all my old collector car's ( where you definitely don't want high speed's ),
XR-311, Cheetah , Sand Scorcher , Ford Ranger ,
Toyota Hilux , Blazing Blazer ( just to name a few )
this motor is perfect for these models !
this motor has the same overall diamensions like a stock 540 Mabuchi motor ,
so it's a direct "bolt on" modification . Beside the low rpm's , this motor is a much higher quality motor ,
check it out :
- modified motor-can
- adjustable timing
- replacable brushes
- about 8000 RPM's at 7.2 volt
- twice as much tourqe as the LRP Truckpuller !
- each motor is hand-build ( each motor get's his own serial-number
for future reference ), tweaked to max performance and dyno-tested
- printed dyno-results and instructions included
the motordata below is updated now
I have increased the tourqe to average 200 Nmm, and power is now average about 45 watt's
for refernce here the comparison from my Truckpuller motor to the stock Mabuchi 540
here a comment from Joe Murray about this motor :

I got a package in the mail from Willy Loewer of Tn, USA containing two
of his own designed 7.2v truck puller motor. I'll let him inform you of
the exact specs. I put one of these motors in my Tamiya Mammoth dump trk
last night & was just trying it out now. With the trk loaded as full as
could be (approx 30lb gvw), the motor has plenty of power to move over
the rough terrain in my dirt basement & the speed has been cut in half
from what the stock kit motor was putting out. I am quite pleased with
the performance of this motor.
This WWR trk puller motor is a definite positive as alternative to
ordering overseas from the UK for the LRP trk puller motor for slower
speeds in these Tamiya semi trks & the cost is a few dollars cheaper
This motor is also perfect for the Tamiya "Tanker's" out there
(for the old type tanks with one 540 type motor and the double clutch setup )
check out the video's of my old Leopard Tank with my WWR-Truckpuller motor !
check out the video of my Tank-transporter with 3:1 Gear-reduction and Truckpuller motor
If you like to get one of these motors :
cost = $ 55.- plus $6.- S/H for the US and Canada .
shipping within the US via insured priority-mail with delivery-
shipping to Canada $ 6.- via Global priority-mail
for the power-hungry Tamiya R/C truckes ,
I have also a 3:1 gear-reduction as alternative to the known 4:1
from Carson . This gear-reduction bolts onto the front from the
Tamiya 3 speed gear-box , does not require new drive-shafts and also
can be used in the Globeliner ( Carson setup does not work in the Globeliner )
and the latest addition is a 7:1 gear-reduction
regards and "keep on trucking"
