This
improves fuel economy, reduces driveline backlash and reduces
vehicle maintenance costs. It also enables the LOKKA
automatic diff locker to be installed to the front differential.
| Fuel
Economy
Obviously there is a reduction in the load on
the engine if the front section of the transfer case,
the front tailshaft, differential, axles and wheels
are not being 'driven'. This reduction in load translates
to increased fuel economy.
Maintenance
Front axle seals, CV joints and the outer drive
flanges wear heavily with constant use, resulting
in expensive and needless repairs several times over
during the life of the vehicle. The cost of overhauling
the front differential housing once
will be nearly twice the cost of fitting the Part
Time Kit alone. |

Other
major parts such as the front tailshaft, axle seal surfaces
on the front axles and the front differential itself also
wear but at a lesser rate than the other parts. These parts
will require repair - at a much greater cost - but fortunately
less often.
Backlash
The existing driveline has multiple points of contact
where 'backlash' or 'play' can occur. There are 3 differentials
in the system with many splined couplings and flanges. The
accumulation of all these points of backlash often result
in the sloppy feel and clunky noises when rapidly changing
throttle position or when changing gears.
Fitting
of the Part Time Kit reduces the total amount of backlash
by 75% in some cases. The vehicle has a much tighter feel
and considerably smoother gear changes. Although less noticeable
in automatic vehicles, the problem still exists. The steering
is also noticeably lighter.
Answer
A simple kit can be fitted to the Transfer Case in approximately
5 hours. No special service tools are required. The existing
centre "Diff Lock" button or lever becomes the
4WD engagement button just as in the late FJ62 &
FJ73 Series Landcruiser factory engagement mechanism. A
quality Free Wheel Hub set is included in the kit. There
are comprehensive fitting instructions for the DIY owner.
An additional benefit of this installation is the Lokka
automatic diff locker can be fitted to the front
differential which greatly improves traction in all 4WD
situations.
