Why Rear Main Seals Fail: The Depth Problem
Rear main seals leak because they're installed too deep, too shallow, or with seal/wear sleeve separation. Improper installation causes:
- Oil starvation – Seal runs dry without wear sleeve protection
- Immediate leaks – Wrong depth = instant failure
- Crankshaft damage – Misaligned seal cuts crank flange
- Warranty claims – $1,500+ per comeback
- Reputation damage – Customers don't return for sloppy work
The ATC ZTSE-4515-C solves this with a precision hub that automatically sets correct seal depth when the drive nut bottoms out. No measuring. No guessing. Factory results every time.
