PROBLEM
Show/hide table
| The existing oil cooler can fail due to a twisted internal bundle on certain 3516B Marine Engines, 3516C Generator Sets, 3516C Marine Engines, 3516C HD Generator Sets, 3516C HD Marine Engines, and 3516C HD Petroleum Engines. If the existing 373-6537 or 10R-5667 Oil Cooler fails it can leak engine oil into the cooling system. |

| Analysis of most recent oil cooler failures indicate that the cooler bundle assembly may have partially collapsed. A collapsed bundle or tube could have been damaged enough to cause a early hour leak failure of the tube that will allow the coolant and oil to mix. Example of a collapsed bundle is shown below: |
| MATERIAL REQUIRED Steel Rod Diameter: 5/32 inch or 4mm Length:48" Reference: McMaster Carr Part Number 8888K236 (Inch) ? 72" long 8116K86 (Metric) ? 72" long 48 inches of clearance from face of cooler after removal of bonnet for rod insertion Oil Cooler part number: 373-6537 and 10R-5667 Duct Tape |
 |
| Image1.2.1 |
| PROCEDURE Cut steel rod to length: 1200 mm (48") Use tape to mark 1080 mm (42.5") from one end of the rod Slowly insert the rod into tubes marked by green dots (center of the tube bundle) shown in Image 1.3.1 in order to obtain feel for good tube. Slowly insert the rod into tubes marked by red dots (top and bottom of the tube bundle) shown in Image 1.3.1. The rod should be able to be inserted with little or no resistance (less than 22 N or 5 lbs). Do not force the rod into the tube if it stops before reaching the full length (1080 mm) indicated by the tape on the rod. |
 |
| Image1.3.1 |
| If the rod can be fully inserted into all marked tubes in red (top and bottom of the tube bundle), then the tube bundle is not collapsed. If the rod cannot be fully inserted into all the marked tubes in red (top and bottom of the tube bundle, then it is likely that the oil cooler has a collapsed bundle. |
