Meritor Tire Inflation System
PART IDENTIFICATION
As the leading automatic tire inflation system in North America, the Meritor Tire Inflation System (MTIS™) with ThermALERT™ Standard is designed to be compatible with a wide range of axle and wheel-end component combinations. To help ensure that you specify the correct MTIS kit for an application, Meritor is pleased to provide the following guidelines to assist in product selection, which depends on the type of axles and wheel-ends on the trailer.
Specify a New or Retrofit Kit
Please determine following information to allow selection of the proper kit:
For Installation on Meritor TP Axles with Parallel Spindles
Specify kits having thru-tee assemblies with 4" long tubes when the trailer axles are equipped with ductile iron hubs except for ConMet hubs. If the trailer axles are equipped with aluminum or ConMet ductile iron hubs, specify an MTIS kit containing thru-tees with 5" long tubes.
Determine the type of kit you need.
MTIS Kit Part Numbers “Partial” MTIS Kits
“Partial” kits do not include spindle press plugs or stators. Partial kits are for installation on axles which have been prepped for MTIS at the production factory. (The spindle press plugs and stators 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 customer service 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.
“Full” MTIS Kits
“Full” MTIS kits and the other components as shown in Figure 5 are for installation on axles which have not been 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 TN axle 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 MTIS order. When a length other than the standard is specified, it will be stated in the kit part number. Refer to the tables below for the axle type and product codes.
Examples of standard kits. Please contact your Meritor representative for assistance to obtain the correct kit for the application.
