Correct serpentine belt part numbers for 1996 Ford 460 FI RV engine?

I'm documenting maintenance specifications for my 1996 RV with a Ford 460 fuel-injected engine and need to establish the correct serpentine belt part numbers for future reference. Multiple parts suppliers have provided conflicting information, and I've encountered issues with incorrect belt lengths and routing specifications from various manufacturers.

What are the verified part numbers for the serpentine belt on this specific engine configuration? I need reliable cross-references that will ensure proper fit and operation without the trial-and-error approach that's been problematic with generic part lookups.

Dear Mike R.,

Quick Answer

For 1996 Ford 460 FI engines in RVs, the correct serpentine belt is typically Gates K060885 or Dayco 5060885. Always verify by measuring your current belt or checking with Ford parts using your VIN for exact specifications.

The Problem

For your 1996 Ford 460 fuel-injected engine, you'll need to verify the correct serpentine belt part number based on your specific engine configuration. Due to variations in RV chassis configurations, measure your existing belt length and count the ribs, then verify routing before purchasing replacements.

The Underlying Issue

Many RV owners encounter these problems when buying belts:

Wrong length: Belt either too long (slips) or too short (won't fit)
Incorrect rib count: 4-rib belts don't work on 6-rib systems
Aftermarket modifications: Previous owners may have changed pulley configurations
Chassis variations: Different RV manufacturers used different accessory layouts

The Solution

Follow these steps:

Safety first: Ensure engine is cool and disconnect battery negative terminal
Locate belt tensioner: Spring-loaded pulley that maintains belt tension
Photo the belt routing: Take a picture before removal for reference
Release tension: Use a 1/2" breaker bar to rotate tensioner in the direction indicated by the arrow on the tensioner (typically counterclockwise)
Remove old belt: Slip belt off the smooth idler pulley first
Install new belt: Follow routing diagram, ensuring proper rib engagement
Check alignment: Belt should sit centered on all pulleys
Release tensioner: Allow spring tension to properly seat the belt
Verify operation: Start engine and check for proper belt tracking

Beyond DIY Territory

Contact a qualified RV or automotive technician if:

Belt routing is unclear: Missing or illegible routing diagram
Tensioner problems: Tensioner won't hold proper tension
Multiple belts: Some 460 engines have separate AC belts
Pulley alignment issues: Belts consistently wear on edges
Accessibility concerns: Generator or other components block access

Avoid Future Headaches

Keep your belt system reliable with these practices:

Inspect monthly: Look for cracking, fraying, or glazing
Check tension annually: Proper tension prevents premature wear
Clean pulleys: Remove debris that can cause belt damage
Replace at 60,000 miles: Don't wait for failure on the road
Carry spares: Always have a correct spare belt in your RV
Document your setup: Keep photos and part numbers in your RV manual
