Why Every MX-11 Inframe Must Include New Crank Seals
DAF/Paccar changed the MX-11 crank seal design in 2017. The old “lip-style” seals leak by 300–400k miles 100% of the time.
New PTFE seals (1923376 front & 1923380 rear) are mandatory during any inframe or overhaul.
Trying to install them without the factory-spec drivers = damaged seals, oil leaks, and $10,000+ repeat repairs.
What’s Actually in the ATC1903058 Kit
- Front seal remover cup + puller plate
- Rear seal remover bridge + forcing screws
- Front seal installer driver (perfect 90° alignment)
- Rear seal installer sleeve (prevents PTFE lip rollover)
- All bolts, washers, and alignment pins
- Heavy-duty metal storage box with custom foam
“Used the ATC1903058 on three MX-11s this month. Rear seal went in perfectly flush first try every time. No more rolled lips or leaks.”
