Pinasco crankcases for Vespa T5

Pinasco has just informed us that on Thursday we will receive the new crankcases for Vespa T5.

The crankcases for the rare Vespa T5 were not easy to find and now we are pleased to have spare parts for Vespa T5 back in stock.

Reed valve and rotary valve crankcases for Vespa T5

As for the PX crankcases, also for Vespa T5 Pinasco offers two types of crankcase:

The price of the T5 crankcases will be slightly higher than that of the crankcases of the PX version. Further technical details will be available as soon as the crankcases will be in stock and we’ll keep you updated on our blog page.

Fitting T5 engine

For a perfect fitting of the engine we suggest you to use this overhaul kit: engine overhaul kit for Vespa 125T5

First pictures of T5 crankcases

Here some pictures which Pinasco provided us. Crankcases are expected to be delivered with all fixed studs and suitable silent buffers for the engine mounting and shock absorber mount.

 

On offer: this engine casing for Vespa smallframe is very high in demand

We were lucky to coincidentally get hold of a few of these legendary LML SE engine casings.

Available in two versions: with e-start preparation and without e-start.

Much bigger transfer ports by standard

The LML SE engine casing is actually comparable to the engine casing of a Vespa PK125XL2. With only one difference: the transfer ports are much bigger than in the Piaggio engine casing.

Replacement or perfect base for tuning

Easily spotted: Both ducts at the sides offer plenty of space for further amendments, which makes it easier to fit strong racing cylinders.

We demonstrated this with a Parmakit SP09:

You can see that there is space for further amendments of the cylinder base: Parmakit-base gaskets on the LML SE – smallframe.

Motorgehäuse PK SE große Überstromkanäle 014

You will only have to invest a little time to perfectly fit such a cylinder to the transfer ports – unlike with a popular engine casing by Piaggio.

3-stud intake

The SE engine casing has 3 intake studs.

The sealing surface of the rotary valve with its 42mm length is rather large, which makes the engine casing an interesting option as rotary valve for performance oriented engine concepts.

Stable bearing seats – allow better crankshafts

You will find the bearing seat and the oil sump for the NBI needle bearing on the ignition side, as usual for PK XL 125. So you can directly use a stable PK-ETS crankshaft with 25mm bearing seat.

The engine casings were developed for the gear selector fork of a XL2 with “one cable system”.

You would like to fit the casing in a Vespa with the usual 2-gear change cable system? You will need a conversion set.
Thanks to its precise machine production in small batches, shifting gears is more precise, which is the big advantage of this solution. The choice of high quality material additionally prevents wear.

SMALLFRAME ENGINE CASING LML SE
SE125 engine casing by LML India. The engine casing of the Indian LML Sensation 125 is a 99% true copy of the casing in a Vespa PK125 XL2. New Piaggio engine casings made in Italy haven’t been available for years. An engine casing by LML therefore is a very good alternative.
The casings are NOS-products, sometimes rust film on metal parts.

PK125 XL2 / PK125 ETS

The engine casing can be used as a 1:1 replacement for PK125 XL2 and PK125 ETS.
Delivered with an adaptor to attach gear change cables.

FEATURES

  • Type of engine casing: PK125 XL2
  • Type of crankshaft: PK 125XL2/ PK125 ETS (24/25mm cone)
  • Bearing seat ignition side: Ø=38mm (PX needle bearing)
  • Type of gear change cable: 1 rigid cable as for PK XL2
  • Intake: long rotary valve surface (42mm)
  • Intake: 3-stud
  • Transfer port: bigger than in serial production

Fitting smallframe crankshafts

Rotary valve

These crankshafts fit (rotary valve, from 125cc):

Bearing sets and gaskets

A fitting ball bearing set comes with flywheel side NBI bearing.

Oil seals and gasket sets are also the same as for the Piaggio ETS version.

 

Gearbox oil for Vespa

SAE30 – gearbox oil for Vespa engines
BGM PRO STREET gearbox oil SAE30* – API GL3
traditional monograde oil as stipulated by Piaggio for all classic Vespas. Perfectly covers all ordinary load conditions and is ideal for any engine, be it mass produced or high end tuning.

  • Mildly alloyed, perfect fit for oil bath clutches
  • Lubricant film with good adherence, pressure resistant
  • Excellent oxidation stability

Improvements

Both versions feature the same reasonable improvements:

  • MATERIAL
    High quality die cast aluminium with a fine surface finish
  • SEALING SURFACES
    Very precisely milled sealing surfaces
  • STRONGER
    Reinforcement ribs near the main shaft bearing on the shifter peg side and the rear shock mounting plate
  • MASSIVE
    Significantly more material used at the cylindre jug barrel’s sealing surface and at the caburetor inlet
  • BEARINGS
    The crankshaft bearing on the alternator side is a large cylindrical roller bearing (NU205 25x52x15mm)
  • OIL SEAL
    The housings are intended for being equipped with a metal oil seal (clutch side). Please use the type for the 200cc versions with a brown sealing lip.
  • LUBRICATION
    Double lubrication hole for the alternator bearing.
  • FIT
    Two additional dowel bushes = crankshafts with an overlong hub do not require the centering edge of the alternator side. Dowel bushes dimensions OØ=9,95mm, IØ=8,40mm, h=13,80mm
  • RUBBER WASHERS
    The included silent rubber washers are stiffer and give the engine a better positioning in the frame
  • NUMBER
    The engine casings do not have an impressed number or prefix on them
  • OIL HOLE
    No oil drain hole for transmission oil = There no longer is a superfluous oil drain hole that shows whether the oil seal on the inside is damaged*.

*We recommend using an encapsulated bearing and an exterior oil seal with a correponding brake drum.

ROTARY VALVE VERSION SPECIAL FEATURES

  • Extra-large sealing surface across both engine block halves, fits all intake manifolds
  • Can be used as a 1:1 replacement for the standard engine casing
  • The 125-150cc version features the same crankshaft housing as the 200cc models and inevitably requires a PX200 crankshaft. The rotary valve’s width was adapted to the dimension of the 200cc models. The narrower gasket of a 125cc crankshaft will not seal the surface here.

REED VALVE VERSION SPECIAL FEATURES

  • Centered full surface reed valve intake
  • Comes with a reed valve intakte manifold, comes with a reed valve in a RD350 format (distance holes 58x48mm)
  • Intake rubber can be turned by 360°, carburetor connecting size Ø=34mm
  • Rubber washer fits Keihin PWK28, Mikuni TMX27/30, Dell’Orto PHBH28/30, VHS24-30
  • No moulded shaft for the oil pump control
  • No hole for an oil pump drive shaft

The dowel bush for the auxiliary shaft that is included needs to be inserted. The casings are meant to be used with an electric starter motor. Therefore, please use the flywheel cover for models with an electric starter motor. For those without electric starter motor, simply cover the hole in the casing with our proper tin panel (7671454). Should you be using other transmission components than the ones of the PX 125cc models, please check whether the auxiliary shaft is compatible and modify it if necessary.
Please apply a high strength locking agent to all stud bolts. The cylinder stud bolts are not oversized on one side as is customary with Piaggio. Therefore, also glue in the Pinasco cylinder stud bolts that come with the delivery. Please make sure that when screwing in the cylinder stud bolts, any oil pump cog wheel that may be mounted can move freely. We recommend cutting all of the threads again and cleaning them out with compressed air.

ASSEMBLY NOTE
The crankshaft bearing NU205 on the alternator side does not fit flush with the edges of the engine casing.
It sticks out about 1mm toward the crankshaft.

    • All stud bolts
    • Silent rubbers + washers for the silent rubbers
