PROBLEM
Show/hide table
The Connecting Rod Bearings and Main Bearings on certain reman 3512 and 3516 machine engines along with 3508, 3512, and 3516 engines installed in various D11R track-type tractors; 785, 789, 793, and 797 off-highway trucks; and 992G and 994F wheel loaders can exhibit a flaking condition of the lead/tin overlay which in some cases has resulted in connecting rod seizure.
Inspect the Oil Suction Screen at every oil change for the first 3,000 hours of operation. Please refer to the attached Rework Procedure for details on how to complete the inspection.
If you identify Lead/Tin Overlay in the Suction Screen, repeat the Suction Screen inspection after 72 hours of normal engine operation.
If you identify Lead/Tin Overlay a second time remove and inspect the Connecting Rod Bearings for flaking. If the bearing has flaked it will appear similar to the bearing shown in Image1. During Rod Bearing inspection, check for bearings identified in the attached rework, and outlined in PI70314 as suspect parts.
NOTE: If the presence of lead/tin overlay is detected, or suspect parts are found, contact your global mining product support representative before proceeding with bearing replacement.
If no Connecting Rod Bearings are flaked, inspect the Main Bearings for the same condition and for any Main Bearings identified as suspect in attached Rework Procedure, and outlined in PI70314.
NOTE: If the presence of lead/tin overlay is detected, or suspect parts are found, contact your global mining product support representative before proceeding with bearing replacement.

PARTS DISPOSITION
Handle the parts in accordance with your Warranty Bulletin on warranty parts handling.
Rework Procedure
Before you begin this procedure make sure you have obtained a filtered paint funnel as shown in Image1.1.1 and a Lead Test Kit similar to the one shown in Image1.1.2 and a magnet.
NOTE: If a Lead Test Kit is not available you can use a magnet to remove the ferrous metal and isolate the non-ferrous material. Then use the blunt end of a punch to determine the hardness of the particles. Lead/Tin Overlay is very soft and malleable.
Image1.1.1
Image1.1.2
After the oil has been drained from the oil pan remove the cover shown in Image1.2.1.
Image1.2.1
After cover has been removed pull out the oil suction screen as shown in Image1.3.1
Image1.3.1
Use solvent and a brush to remove particles from the suction screen and collect the solvent and particles into a clean container.
Pour the solvent and particle mixture through the filtered paint funnel shown in Image1.1.1 to separate the particles from the solvent.
After particles have been separated from the solvent use a magnet to separate out the ferrous metal and leave the non-ferrous particles.
Take the Lead Test Swab shown in Image1.1.2 and rub the swab onto the particles. Use the instructions in the Lead Test Kit to determine a positive indication of lead.
All connecting rod and main bearings mentioned above with the following bearing production year code "NO" and bearing month codes UG, UH, UI, UJ, UK, or UL. Refer to Image1.6.1
