Guide Pin is too long
The standard guide pin
on the TR-3 and NC-2 is designed for the newer tracks with deeper and
wider slots.
If you are using some of the older track, try the supplied plastic guide
pin or purchase a shorter metal pin (available separately)
Pick-up Shoe Adjustment
The angle on the "elbow" of the shoe is too sharp.
This causes the top of
the p/u shoe to lose contact with the brush barrel.
Fix:
Straighten the "elbow"
a little until the bend is flush with the bottom of the chassis.
Chassis Lubrication
All chassis should be
lubricated where indicated on the schematic (in red)
We recommend a light synthetic oil on the bearings and axles and a
Teflon grease on the gears.
A drop of oil at each location and a small dap of grease is sufficient.
A plastic safe lubrication must be used and we recommend the
Labelle products (#106 and #108)
TR-3
DR-1
Gear Adjustment
All chassis are tested prior to shipment. However, there can be
instances where the gears may be tight.
In most cases, the gears will wear in and have no ill effects.
If the chassis does get hot, insure that the gears move smoothly.
If they are tight, some material may be removed from the hub or the
spacer moved away from the pinion.
Wheel Base Adjustment
All JAG Hobbies chassis have an adjustable wheel
base (except for the PR-5)
To adjust:
Snap front axle assembly out from the top and snap back in desired
location (Note: does not apply to the DK-4)
DK-4:
Use a wheel puller (you can also use a screw driver to pry it off) to
remove one of the front wheels, remove the axle, put in desired location
and reinstall wheel.
