The Critical Risks of Damaged Rear Crank Seals in Volvo Mack Engines

• Oil leaks – Damaged lips drip oil, requiring $500–$1,500 reseals
• Contamination – Debris enters, leading to $2,000–$4,000 bearing jobs
• Crank wear – Misalignment scores surfaces, costing $1,500–$3,000 machining
• Downtime losses – Improper install extends service 1–2 hours, adding $200–$400 labor
• Seal failure – Uneven seating causes repeats, totaling $1,000–$2,000
