If the axle was MTIS prepped at factory, use MTIS Prepped Kit (less pressplugs and stators).2. Identify wheel size, wheel type (steel or aluminum) and determine axle count. Use the charts below to select the correct retrofit kit.3. See Page 8 to select the appropriate style of hubcaps (hubcaps included in full ThermALERT kits).4. Determine hub material - Ductile Iron or Aluminum and hub type - Standard, PreSet or PreSet Plus .NOTE: All retrofit kits are pre-set to 100psi.

Guidelines for Specifying the Correct Kits for the Meritor Tire Inflation System(MTIS ) with ThermALERT StandardAs the leading automatic tire inflation system in North America, the Meritor Tire Inflation System (MTIS ) withThermALERT Standard is designed to be compatible with a wide range of axle and wheel-end componentcombinations. To help ensure that you specify the correct MTIS kit for an application, Meritor is pleased to provide the following guidelines concerning the length of the thru-tee tube, which depends on the type of axles andwheel-ends on the trailer.For Installation on Meritor TN/TQ Axles with Tapered SpindlesSpecify kits having thru-tee assemblies with 3.5” long tubes when the trailer axles are equipped with ductileiron hubs. If the trailer axles are equipped with aluminum hubs, specify an MTIS kit containing thru-tees with 4”long tubes.For Installation on Meritor TP Axles with Parallel SpindlesSpecify kits having thru-tee assemblies with 4” long tubes when the trailer axles are equipped with ductile ironhubs. If the trailer axles are equipped with aluminum hubs, specify an MTIS kit containing thru-tees with 5”long tubes.For Installation on Meritor TN/TQ or TP Axles Equipped with PreSet or PreSet Plus Wheel EndsSpecify kits having thru-tee assemblies with 5" long tubes.MTIS Kit Part Numbers “Partial” MTIS Kits“Partial” kits do not include spindle press plugs or stators. Partial kits are for installation on axles prepped for MTIS. (The spindle press plugs andstators have been installed on the axles.)Note that the standard thru-tee length for partial MTIS kits is 3.5”. If you require a longer thru-tee length, please inform your Meritor customerservice representative when placing your MTIS order. When a length other than the standard 3.5” is specified, it will be stated in the kit part number.Refer to the following table for examples.(Thru-tee Tube Length)Recommended ThruTee Tube LengthMTIS with ThermALERT Kit NumberTN axle with ductile iron hubs3.5”H2712-22TN axle with aluminum hubs4”H2712-22-4TP axle with ductile iron hubs4”H2712-22-4TP axle with aluminum hubs5”H2712-22-5TN/TQ or TP axle with PreSet or PreSet Plus hubs5"H2712-22-5Trailer Axle and Hub types“Full” MTIS Kits“Full” MTIS kits are for installation on axles not previously prepped for MTIS. These kits include spindle press plugs and stators.The standard thru-tee tube length for a full MTIS kit is based on the spindle type for which the kit is intended. For example, a full MTIS kit for a TNaxle will have a standard thru-tee tube length of 3.5,” while a full MTIS kit for a TP axle will have a standard thru-tee tube length of 4”.If you require a thru-tee length longer than the standard length, please inform your Meritor customer service representative when placing your MTISorder. When a length other than the standard is specified, it will be stated in the kit part number.
