99crpt1000 top tpr factory engine crankcase piaggio 100cc lc

TECHNICAL FEATURES
– Built in 6082 Anticorodal Alloy (Al-Si-Mg-Mn Alloy)
– Pump crankcases sized for the installation of crankshafts with stroke up to 47mm with connecting rod center distance 95/96mm, without any additional intervention.
– Exclusive housing for PVL internal rotor ignition.
– The use of the electric cooling pump, to eliminate the power absorption of the traditional mechanical pump.

– Increased coolant passage sections

VERSIONS AND COMPATIBILITY
Particular attention has been paid to absolute compatibility.
With this crankcase, we can interchange:
– Semi-chambers (70cc / 100cc / prototypes)
– Single arm (long / short)
– Braking system (disc / drum)
– Model (Piaggio / Minarelli)
Available versions:
– Piaggio 70cc cod. 99CRPT0700
– Piaggio 100cc cod. 99CRPT1000
**POSSIBILITY TO SATISFY ANY APPLICATION WITH A SINGLE HALF CHAMBER

EXTENDED STEP
The wheelbase has been lengthened by moving the wheel axle position 10mm towards the rear and 10mm towards the tarmac.
This solution improves the chassis and allows the use of a rear shock absorber 10mm shorter, reducing
the inclination of the power supply and the crankcase.
**KEEPS THE TRANSMISSION LENGTH AND RATIOS UNCHANGED (possibility of fitting any brand)

REVERSE GEARBOX WITH EXTENDED WHEELBASE
The gear box has been radically innovated, introducing an increase in the step.
It was turned inside out with an opening towards the outside
This allows the elimination of the gear cover, improving the precision of the coaxiality, furthermore an o-ring guarantees an optimal oil seal.
**KEEPS THE TRANSMISSION LENGTH AND RATIOS UNCHANGED (possibility of fitting any brand)

FLANGED OIL SEALS
The oil seal housing now features two flanged bushings, which allows for the
boring of both bearings in one operation, together with the bearing surface
cylinder obtaining an absolute concentricity and diametrical tolerance of both seats.
Reducing the shaft stress on the bearings and increasing power and delivery.

INTEGRATED DEMOUNTABLE TORSEN
Completely revised, the torsen now features a much more compact diameter attachment,
without acting on the exhaust holes (as is instead the case for all competitors).
This allows for a much more solid connection and two calibrated pins are also provided.
for perfect alignment.
Furthermore, the section of over 14mm is much more robust than other proposals.

INCREASED POWER SUPPLY
The power supply has been radically redesigned.
In addition to being able to accommodate larger valves and carburetors, it also allows for a better layout
of the carburetor in relation to the wheel.
Furthermore, thanks to a double drilling pattern it is possible to mount both larger valves and
valves already in use, with 60x40 interaxis (e.g. AM6)
**WITH COMMERCIAL DRILLINGS (possibility of fitting any brand)

OPTIMIZED VENTILATION
Ventilation in the TRANSMISSION area has been significantly optimised.
Many problems are caused by high temperatures; now features two generous passes (in
input and output) and also a central extraction area for the variator.
Possibility of installing forced air flows on the inlet air intake.

(fit any brand)

INCREASED TRANSMISSION HEADQUARTERS
As standard, the TRANSMISSION seat is undersized for the full travel of the components,
frequently causing the belt to slip and break.
Overall diameters for variators up to 111mm and for correctors up to 145mm are now foreseen.
With the same usage, the larger volume also generates better heat dissipation.

STRONG SECTION TREE AREA
To date, no engine crankcase can boast such resistance in the crankshaft area.
This section guarantees a more durable flatness and quality of the couplings.
All the processes are managed on a 5-axis palletized work center, leader in the sector
Automotive and certificates on measuring machines.
**BEST VALUE IN THE INDUSTRY
**MAINS THE POSSIBILITY TO ACCOMMODATE ANY SHAFT AND TRANSMISSIONS

RESISTANT SECTION TRANSMISSION AREA
To date, no engine crankcase can boast such resistance in the TRANSMISSION area.
Using the Finite Element Method (FEM) it was balanced and
compensated the structure of the single-arm, effectively cancelling out any twisting moment given by the
wheel axle overhang load.
Thanks to the centering pin of all components, it improves alignment compared to other
solutions.
**IT MAINTAINS THE POSSIBILITY OF ACCOMMODATION OF ANY TYPE OF TRANSMISSIONS

RESISTANT SECTION WHEEL AXLE AREA
The structure in the gear box was increased using FEM simulations.
In addition to the increase in stresses, we have considered the total adoption of bearings for
improve the accommodation of relationships, decreasing relationship misalignments that generate heat and
decrease the power to the wheel.

LARGER SCREWS
Increasingly high-performance engines require extreme safety in couplings.
To date, the use of M6 screws on aluminum is undersized and critical in the available crankcases
on the market.
We managed to redesign the entire crankcase with M8 screws for all couplings (with section
resistant +70% compared to an M6).
This increases the stability and the degree of safety of the user.
**THE ONLY CARTER TO ADOPT M8 THREADS FOR TORSEN-SINGLE-ARM-RATIOS

SINGLE-ARM COUPLING
An in-depth study to optimize the coupling between Semi-Chambers and Single Arm guarantees
stable and long-lasting employment.
In addition to centering and phase, special attention was also paid to homogeneous distribution.
of the load of the screws, positioning them in areas equidistant from each other and from the centre, completely in
