1998 Caterpillar 3116

Component

Engine And Engine Cooling:Engine:Diesel

Consequence of Defect

equipment description: mechanically unit injected diesel engines. the governor of the engine controls the unit injector fueling by way of a control assembly. in this assembly, a link to the governor is joined to the control rod using a rivet. this rivet can loosen and then wear resulting in engine speed instability.

Corrective Action

if not identified and corrected, engine speed control could be lost due to rivet disengagement.

Recall Notes

dealers will inspect the control assembly and replaced if necessary.

1997 Caterpillar 3116

Component

Engine And Engine Cooling:Engine:Diesel

Consequence of Defect

equipment description: mechanically unit injected diesel engines. the governor of the engine controls the unit injector fueling by way of a control assembly. in this assembly, a link to the governor is joined to the control rod using a rivet. this rivet can loosen and then wear resulting in engine speed instability.

Corrective Action

if not identified and corrected, engine speed control could be lost due to rivet disengagement.

Recall Notes

dealers will inspect the control assembly and replaced if necessary.

1996 Caterpillar 3116

Component

Fuel System, Gasoline:Delivery:Fuel Pump

Consequence of Defect

model no.: 3126e hydraulically controlled electronically actuated unit injected diesel eingines with high efficiency pumps (hep8) produced by caterpillar between june and september 2002 for use on medium duty on-highway engines. the pump components may experience a high pressure seal failure which can result in a short period of rough running and subsequent engine stall due to a loss of injection actuation pressure.

Corrective Action

once engine stall occurs the engine cannot be restarted, which may result in a situation where a vehicle crash could occur.

Recall Notes

owner notification began december 23, 2002. owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact caterpillar at 1-800-447-4986.

1990 Caterpillar 3116

Component

Engine And Engine Cooling:Engine

Consequence of Defect

incorrect torque on the governor input assembly could cause it to loosen and back out, interfering with the governor housing operation. also the torsion spring on the accelerator input was installed incorrectly and could dislodge, preventing the governor and accelerator from properly controlling the engine speed.

Corrective Action

without governor operation, the driver could overspeed the engine, causing loss of control of vehicle speed.

Recall Notes

assure proper assembly and torque on 8c8580 bolt, and proper installation of 7w9526 torsion spring.

1989 Caterpillar 3116

Component

Engine And Engine Cooling:Engine

Consequence of Defect

incorrect torque on the governor input assembly could cause it to loosen and back out, interfering with the governor housing operation. also the torsion spring on the accelerator input was installed incorrectly and could dislodge, preventing the governor and accelerator from properly controlling the engine speed.

Corrective Action

without governor operation, the driver could overspeed the engine, causing loss of control of vehicle speed.

Recall Notes

assure proper assembly and torque on 8c8580 bolt, and proper installation of 7w9526 torsion spring.
