Preview: Engine casing -PINASCO Slave, reed valve intake- Vespa T5 125cc

Description

The Pinasco motor housings are very high-quality replacement motor housings made of the finest die-cast aluminium. In addition to the very precise machining, they also offer many special features that are particularly interesting for tuners.
In addition to the significantly larger sealing surfaces at the cylinder base and carburetor inlet, Pinasco also offers the housings as a version with diaphragm inlet. This intake technology, which has long been a standard in the automatic sector, offers even large carburettors a good passage to breathe deeply. Further reinforcements in the casting, a larger crankshaft bearing as well as the great scope of supply round off the superbe overall picture of the Pinasco engine housing perfectly.

The housings are manufactured in two versions:
MASTER = SLAVE = MEMBRANE CONTROLLED

The engine internals and ignition components of all 125-200cc models from 1982 onwards can be used. The components from model year 1984 onwards are preferable due to the improved and more stable transmission and the more powerful alternator. The engine of the COSA models is also well suited as a donor engine. Their engine block is different on the outside, but uses the same internals as the PX models from 1992 onwards.

Both versions have the same useful improvements:

MATERIAL
High quality die-cast aluminium with fine surface finish
SEALING SURFACES br /> Very precisely milled sealing surfaces
STRENGTHENER br /> stiffening ribs in the area of the main shaft bearing on the control panel side and the shock absorber support
MASSIVE
Significantly more material in the area of the cylinder base sealing surface and the carburettor inlet
Shaft seal ring
The housings are manufactured to accommodate a metal shaft seal ring (clutch side). Here please always use the version for the 200cc versions with brown sealing lip.
FIT
Two additional fitting bushes = crankshafts with extra long stroke can do without the centering edge of the lima half. Dimensions bushes AØ=9,95mm, IØ=8,40mm, h=13,80mm
GUMMIS
The drillings for the large silent rubbers are Ø=44mm (original Piaggio Ø=43mm).
The enclosed silent rubbers are stiffer and offer a better guidance of the engine in the frame.
Piaggio silent rubbers also fit. Solutions with metal bushings or without preload do not usually fit if they are made for Piaggio motor housings (Jockey, PLC).The motor housings do not have a stamped motor number or prefix
NUMBER
The motor housings do not have a stamped motor number or prefix
OIL DRILLING
No drip hole for gear oil = The nonsensical drip hole indicating whether the internal shaft seal is defective has been omitted*.

*Our tip: Run sealed bearing and external shaft sealing ring with corresponding brake drum.

SPECIAL FEATURES ROTARY SLEEVE VERSION

- Can be used as a 1:1 replacement for an original motor housing
SPECIAL FEATURES MEMBRANE VERSION
- Central, full-surface diaphragm inlet
- Incl. Membrane suction port, incl. Diaphragm in RD350 format (perforated 58x48mm)
- Rubber intake rotatable 360°, connection width carburettor= Ø34mm
- Rubber suitable for Keihin PWK28, Mikuni TMX27/30, Dell'Orto PHBH28/30, VHS24- 30
- No shaft for oil pump control cast in
- No bore for oil pump drive

The enclosed fitting bush for the auxiliary shaft must be inserted by yourself
If other gear components than those of the PX models from 125cc on are to be used, please check the auxiliary shaft axis for compatibility beforehand and if necessary
Please use high-strength adhesive for all studs. The cylinder studs do not have a one-sided oversize as is usual with Piaggio. Therefore, glue in the Pinasco cylinder studs supplied. We recommend that all threads be cut and cleaned with compressed air.
ASSEMBLY NOTE:
The alternator-side crankshaft bearing NU205 is not flush with the engine housing.
It protrudes approx. 1mm in the direction of the crankshaft.
