101-2850 DecalThere have been no problems with users trying to install axial seal "Secondary" elements in radial seal canisters. The axial seal "Secondary" element will not fit in a radial seal canister because the axial seal "Secondary" element has a 6 or 8 bolt hole flange which gets in the way of the radial seal canister sealing ring.
The problem occurs when users install an axial seal "Primary" filter element in place of a radial seal "Primary" element. See the illustration for the difference between the sealing ends of the radial seal (top) and axial seal (bottom) "Primary" elements. The following are some of the problems that may occur:
* If an axial seal element is placed in the radial seal canister, the gasket seal contacts a curved surface that side loads the seal and may rip the seal from the filter end cap.* The axial seal element may be too long for the canister. This may cause the element to buckle and allow the expanded metal outer wrap to contact the filter media. This may result in a hole in the filter media. Also, extra strain will be placed on the cover latches which could result in a latch failure or ripping of the canister.* The cover may not seat on the canister lip. This could reduce the effectiveness of the precleaner.* If an axial seal "Primary" element is placed in a converted air cleaner housing with a radial seal "Secondary" element, there is a possibility that the "Primary" element closed end will contact the "Secondary" element closed end prior to the seating of the "Primary" element sealing surface. This depends on the model of the air cleaner and the manufacturer of the "Primary" element. This can result in:* Unfiltered air bypassing the "Primary" element.* Early plugging of the "Secondary" element.* Extra strain on the filter canister latches.* Reduced effectiveness of the precleaner.
