Subtask 70-27-00-110-055-A ** ON A/C NOT FOR ALL
WARNING:
BE CAREFUL WHEN YOU USE CONSUMABLE MATERIALS. OBEY THE MATERIAL MANUFACTURER'S INSTRUCTIONS AND YOUR LOCAL REGULATIONS.
A. General NOTE: Always obey the specific procedures and limits in the AMM maintenance task.
(1) This task gives the necessary instructions for the removal of oils, grease, hydraulic fluid and loose soil from the engine exterior surfaces (that is, the outer surfaces of the engine) or external parts, which decreases the time necessary to clean the disassembled Quick Engine Change (QEC) parts. This procedure does not remove hard, baked-on carbon. Subtask 70-27-00-110-056-A ** ON A/C NOT FOR ALL
A. Procedure to Remove Grease from the Exterior Surfaces of the Engine by Method A or Method B
(1) Method A
(a) Install covers on all the openings of the engine (this includes the inlet, exhaust, all bleeds, fire extinguishing nozzles, open fuel lines, open oil lines, breather tubes and open electrical connectors).
(b) Clean by one of the subsequent procedures:
2 Apply one of the subsequent gel-type cleaners (listed below) with the correct spray applicator. Do not use a steam machine to apply the gel-type cleaner.
(c) Let the cleaner solution or gel-type cleaner stay on the engine between 10 and 20 minutes.
(d) Flush the engine fully with warm or hot water or with steam.
(e) Remove the covers from all the openings on the engine.
(2) Method B (local application only). Use one of these procedures:
(a) Apply aqueous cleaner (Material No.P11-049) , as received, by spray or with a clean lint-free cotton cloth (Material No.P05-005) . If necessary, use a BRUSH - NON METALLIC, SOFT (not made of metal) or Scrub Pad (Material No.P05-421) orP05-422 pad, scrub
(b) Apply a solvent from SPOP 208.
P05-422 pad, scrub
a If engine parts are hot, let the temperature of the parts decrease to a temperature at which you can touch the parts without gloves, and then apply the SPOP 208 solvent (Ref. AMM TASK 70-27-00-910-804).
Subtask 70-27-00-110-057-A ** ON A/C NOT FOR ALL (1) Method A
(a) Install covers on all the openings of the engine (this includes the inlet, exhaust, all bleeds, fire extinguishing nozzles, open fuel lines, open oil lines, breather tubes and open electrical connectors).
(b) Clean by one of the subsequent procedures:
NOTE: Service experience shows that the gel-type cleaners are more effective than the spray, steam and foam solutions on very dirty engines because the gel cleaners stay on the engine better than the spray, steam and foam solutions, which drain off the engine during the soak time.
1 Mix one of these materials with water to make a cleaner solution at a concentration that is equal to or less than the maximum specified concentration, then apply this solution as a spray, steam or foam: | Specification (Material No.) and Name | MAXIMUM CONCENTRATION (Mixed with Water) |
|---|---|
| alkali cleaner (Material No.P11-031) | 30 percent by volume |
| alkali cleaner (Material No.P11-040) | 30 percent by volume |
| alkali cleaner (Material No.P11-044) | 25 percent by volume |
| alkali cleaner (Material No.P11-045) | 25 percent by volume |
| aqueous degreaser (Material No.P11-071) | 20 percent by volume |
| aqueous degreaser (Material No.P11-072) | 25 percent by volume |
| aqueous degreaser (Material No.P11-073) | 50 percent by volume |
| aqueous degreaser (Material No.P11-079) | 20 percent by volume |
| aqueous degreaser (Material No.P11-080) | 25 percent by volume |
| aqueous degreaser (Material No.P11-080) | 30 percent by volume |
| aqueous degreaser (Material No.P11-082) | 25 percent by volume |
| aqueous degreaser (Material No.P11-083) | 20 percent by volume |
NOTE: It is necessary to use a special applicator to apply the gel-type cleaners. Refer to the gel manufacturer's instructions for the correct applicator.
| Specification (Material No.) and Name | CONCENTRATION |
|---|---|
| alkaline gel cleaner (Material No.P11-047) | As received |
| alkaline gel cleaner (Material No.P11-048) | As received |
| alkaline gel cleaner (Material No.P11-069) | As received |
| alkaline gel cleaner (Material No.P11-070) | As received |
(d) Flush the engine fully with warm or hot water or with steam.
(e) Remove the covers from all the openings on the engine.
(2) Method B (local application only). Use one of these procedures:
(a) Apply aqueous cleaner (Material No.P11-049) , as received, by spray or with a clean lint-free cotton cloth (Material No.P05-005) . If necessary, use a BRUSH - NON METALLIC, SOFT (not made of metal) or Scrub Pad (Material No.P05-421) or
(b) Apply a solvent from SPOP 208.
WARNING:
BE CAREFUL WHEN YOU USE CONSUMABLE MATERIALS. OBEY THE MATERIAL MANUFACTURER'S INSTRUCTIONS AND YOUR LOCAL REGULATIONS.
1 Use a BRUSH - NON METALLIC, SOFT (not made of metal), a Scrub Pad (Material No.P05-421) or a If engine parts are hot, let the temperature of the parts decrease to a temperature at which you can touch the parts without gloves, and then apply the SPOP 208 solvent (Ref. AMM TASK 70-27-00-910-804).
B. Procedure to Clean the Engine External Component Parts after Removal of the Parts from the Engine
(1) When it is necessary to clean engine external component parts after removal of the parts from the engine, do one of the subsequent procedures to clean the parts:
(a) Do Method A above.
(b) Do Method B above.
(c) Do the subsequent procedure:
1 Apply Petroleum Solvent (Material No.P11-027) to the parts with a brush in a solvent-recirculating parts washer or washer/soak tank that uses a recirculating pump to supply filtered solvent to the brush through a flexible supply hose.
2 Wipe the parts dry with a clean lint-free cotton cloth (Material No.P05-005) .
