DT466E And DT530E Liner O-Ring Change

Navistar DT466E Diesel Engine | Highway and Heavy Parts

Near the end of 2004, International Navistar made a change in the DT466E and DT530E cylinder liner o-ring configuration.

This involved them moving from the "old" style liner that used both an o-ring and crevice seal to the simplified "new" style liner that just uses a crevice seal.

Navistar introduced a new O-Ring Kit that includes both the o-ring and crevice seal to cover both the old and new designs. The new single groove cylinder sleeve uses only the large (orange) crevice seal. We have this O-Ring Kit available on our website, it's built to OEM specifications at up to 50% off OEM prices!

How to Identify Old and New Style O-Ring Liners

Old Cylinder O-Ring Liner:

As you can see in the example above, the old style cylinder liner has both an o-ring seal and a crevice seal. The arrow pointing to the ring labeled "1" is the crevice seal. The arrow pointing to the ring labeled "2" is the bottom o-ring.

The new style liner only uses a crevice seal. You can see it labeled "1" in the image above. If you're in the market for a new cylinder kit, we have them available on our website. They're equal or better quality compared to the OE at a much lower cost! You can't beat that.
