TECHNICAL BULLETIN No. 020-2013

12-11-2013

Model: Moto Guzzi 1200 8V engines
Subject: Operations on valve bucket tappets

Dear Dealer,

as part of our research aimed at improving the characteristics of use of our products, we have
already introduced a new solution from 2012 for the timing system components which led to
replacing the bucket tappets with rollers in the 1200 8V engines which are also able to ensure
an extended life for the part.
The following models are affected (1200 8V):
-

Norge

-

Griso

-

Stelvio

-

1200 Sport

The new components (rollers) will be replaced only if operations are carried out on the
timing system due to wear of the bucket tappets which, as well known, generally occurs
with excessive noise of the timing system. Therefore we ask you to ensure that the vehicle
has actually shown signs of problems with the timing system prior to carrying out replacement
operations.

In addition to the vehicles covered under warranty, for which the operation will follow routine
procedure, Piaggio has decided to offer the opportunity to all customers (therefore even those
who cannot take advantage of the warranty) whose vehicle has developed abnormal wear of
the timing system not caused by the customer's use, to replace the bucket tappets with rollers
at the cost of the labour alone. In these cases Piaggio will provide the parts required to
implement the solution in question free of charge. Therefore, for the vehicles not under
warranty, Piaggio will provide a free supply (under warranty) of the required parts (KIT),
whereas the labour will be charged to the customer.

The repair operation may be different depending on the vehicle serial number, therefore it is
important to follow the instructions in the operational technical note below.

Considering the company decision to make this exception and bear costs which it
otherwise would not be bound to bear, please note that the operation will be carried
out exclusively following careful verification of the vehicle fault. No preventive
operations will be accepted regarding vehicles that do not have the problem of wear on
the affected parts (bucket tappets). We will monitor the correct implementation of this
technical bulletin.

Operational technical note

Transformation kits are being prepared for use depending on the type of cylinder head
installed on the vehicle in question. In this initial phase only Kit A will be available for
repair of vehicles (Griso-Stelvio-Norge) fitted with floating type cylinder head covers.
These can be recognised by the presence of the circlip in the spark plug hole area (see
Kit A Operating Procedure).

The operating method must be carried out as indicated below:

Vehicles under warranty
1. Certification (by the Workshop) of the fault relative to wear of the bucket tappets (noise,
visual check and photographic documentation of the wear).
2. Verification (by the Workshop) of the type of cylinder head installed, needed to identify
the correct kit to be used (see Kit A Operating Procedure).
3. Entry of a warranty claim for KIT A, part No. 1A002060, and for the specific labour
code MCG039, with the declaration “spare part not available” (in countries where

applicable only), with attached mandatory photographs providing evidence of bucket
tappet wear (showing type of tappet cover) and, if not already in the system, copies of
service coupons for all services performed to date (maximum size of .zip file 3MB).
4. Warranty claim suspended for evaluation by Authority.
5. Acceptance/Rejection of the warranty.
6. If claim is accepted, shipment of requested kit (in countries where applicable only).
7. Carrying out of the operation.

Vehicles not under warranty
1. Certification (by the Workshop) of the fault relative to wear of the bucket tappets (noise,
visual check and photographic documentation of the wear).
2. Verification (by the Workshop) of the type of cylinder head installed to identify the
correct kit to be used (see Kit A Operating Procedure).
3. Insertion of a Help Desk ticket (Sub-Type “Operations on valve bucket tappets”), to
request release of the frame required for the next warranty request.
4. Entry of a warranty claim for KIT A, part No. 1A002060, and for the specific labour
code MCG040 (for a sum of €0), with the declaration “spare part not available” (in
countries where applicable only), with attached mandatory photographs providing
evidence of bucket tappet wear (showing type of tappet cover) and, if not already in the
system, copies of service coupons for all services performed to date (maximum size of
.zip file 3MB). Additionally, the sub-type “Operations on bucket tappets” indicated
in point 3 must also be specified in the HD ticket.
5. Warranty claim suspended for evaluation by Authority.
6. Acceptance/Rejection of the warranty
7. If claim is accepted, shipment of requested kit (in countries where applicable only).
8. Carrying out of the operation.

NOTE: Proceed with the repair work ONLY after positively identifying and documenting
the fault and after receiving authorisation from Piaggio. No preventive operations will
be accepted regarding vehicles that do not have the problem of wear on the affected
parts (bucket tappets).

The fault with the parts being replaced should not be considered to be connected to the safety
of the vehicle.

OPERATING PROCEDURE

Subject: matching the kit to the engine in question

KIT A: P/N 1A002060

To verify whether the vehicle can be modified with kit A remove the timing cover and check
whether it is the floating type, which can be recognised by the presence of the circlip in the
spark plug hole area:

Fit the old rockers in the new cam tower, fasten the rocker retainer cap, installing the new
ground plate part No. B013661 between the retainer cap and the fastener screws (tightening
torque 18 Nm);

Note: in order to ensure that the rockers stay in their seat, bind the rockers temporarily with
an elastic band

P/N B013661
Insert the cam tower on the cylinder head and proceed restoring the head as per the
Workshop Manual.

IMPORTANT NOTE: Once the procedure is complete, reset the self-adaptive
parameters with the P.A.D.S. diagnostics tool to ensure that the new engine
configuration is recognised correctly.

The Technical Help Desk of our Technical Support Service may be contacted whenever
necessary should you require any additional information or support.
