1.5. REASON 
Excessive use of the assembly tool p/n AE300T012-1, which may cause gear pre-damage during 
assembly. This condition, if not corrected, may cause premature failure of the high-pressure 
pump drive gear, resulting in rail pressure loss and engine shutdown. 
1.6. TIME OF COMPLIANCE 
For E4A engines • Before the total time in servi ce of the affected driving gear 
reaches 40 FH (1), or 
• during the next scheduled maintenance,  
whichever occurs first. 
 
For E4B/C/P engines • Before the tot al tim e in service of the affected driving gear 
reaches 80 FH (1), or  
• during the next scheduled maintenance, 
whichever occurs first. 
 
 (1) Note: Total time in service of the affected driving gear must be counted 
from the installation of an affected part (driving gear) on an engine. For example, if an 
affected part is insta lled on an E4A Engine having 480FH, the driving gear must be 
replaced before reaching 520FH; if an affected part is installed on an E4B/C/P engine 
having 480FH, the driving gear must be replaced before reaching 560FH. 
 
 Note: For a twin -engine aeroplane that has one or t wo affected E4B/C/P 
engine(s) installed, a single ferry flight is permitted to bring the aeroplane to a location 
where the actions required by this Service Bulletin can be accomplished on the affected 
engine(s). 
1.7. CONCURRENT DOCUMENTS / REFERENCES 
Unless specified differently, the latest revision of the concurrent/referenced documents 
applies 
• Maintenance Manual E4.08.04 
• MSB-E4-035 
1.8. OTHER PUBLICATIONS AFFECTED 
None

Manufacturer: Förch, Product ID.: R510)  
5. Visually inspect the driving gear against colour criteria in Table 2 - Driving gear 
check.  
If the acceptable criteria are not met: 
• remove the camshafts according to the Maintenance Manual, Doc. No. 
E4.08.04, Section 85-30-00 Subparagraph 4A (a) - (h) 
• Inspect the cylinder head, camshaft gear, the inlet/outlet camshaft bushing in 
accordance with the Service Bulletin MSB-E4-035, replace the parts as necessary. 
 
2.1.2. Installation of the new driving gear 
 
2.1.2.1 Driving gear p/n E4A-30-000-201 rev. AB1 or E4A-30-000-601 
1. Install the new drive gear in accordance with the instructions in Maintenance Manual, 
Doc. No. E4.08.04, Section 73-10-03, Paragraph D (replace the nut, if required).

block the gear. 
2. Install the HPP in accordance with the instructions in Maintenance Manual, Doc. No. 
E4.08.04, Section 73-10-03, Paragraph B. Refer also to Table 3 for the tightening 
sequence of the screws. 
3. Mark a tool cycle on the Tool Cycle Recording Sheet (included as appendix in this 
Service Bulletin) and fill the execution report. 
Note:  One cycle equals the disassembly of the old gear and the installation of the new 
gear. 
CAUTION: When the assembly wrench has reached 100 cycles, discard the tool. 
4. Conduct an engine ground run of 15 mins, of which 5 mins are MTOP (maximum 
take-off power).

Part acceptable:    
Note: • The possible discoloration shown in the non-acceptable gears is due to high 
friction, which generates heat. When present, the typical discoloration is 
not homogeneous and presents different shades from black/blue to 
violet/bronze. 
• Check the gear according to the discoloration criteria provided.  
• Discoloration is clearly visible on the outer surface of the gear  and in the 
marking zone of the gear.  
• Check also for visible discoloration on the face of the teeth. 
• Check for excessive wear of the gear.
