Pump References
Pump designations include LA1231061 / 6422300065, ST784-M1-A / 6422300765 and LA1231065 / 6422300165. Keep the model/pump groups above distinct. Additional Dodge brand context requires matching the original pump reference; a brand name alone does not establish fitment.
Kit Contents and Material
- Front main vacuum pump seal.
- Gasket.
Seal material: fluorocarbon (Viton).
When to Inspect the Pump
Inspect worn or damaged sealing components, oil leakage and unstable pump operation. Check the housing face, sealing seats and system vacuum before repair. A worn housing may require pump assembly replacement.
Repair Scope
The kit supplies sealing components for the pump, rather than a complete pump. Housing wear or damage can require work beyond resealing.
Important Before Ordering
Compare the original part number, marking, shape and mounting design before ordering. A model name alone does not confirm the required version.
