Please Note: Some Caterpillar C15 engines use an "Isolation Seal" for the underframe stiffener plate. (Manufacturer Part number 168-5248) This item is not included with our kits, as Caterpillar suggests reusing this gasket up to 3 times before replacement. Please inspect your isolation seal. If you require a replacement, it will need to be ordered separately.
Approximately 7 liner and o-ring changes for 3400 series Caterpillar engines between 1982 and 1998 led IPD and our customers to work on ways to extend the life of the bottom o-rings on these engines. Our suspicion was that the o-ring failures in most cases were due to excessive liner movement.
Thus the IPD Crevice-seal style cylinder liner was developed to help reduce that movement by utilizing the tapered crevice seal. This has been sold  successfully by IPD for over a decade. Don't be fooled by imitations! Only the IPD 'CS' liner offers all the features mentioned below and is backed by IPD's  comprehensive warranty.
