GLOW PLUG

Case, and IH Tractor Glow Plugs: An Essential Component for Starting

A glow plug designed for agricultural diesel engines

The glow plug is an essential component for the proper operation of diesel engines, particularly in agricultural tractors used under sometimes challenging conditions. It heats the combustion chamber to facilitate ignition of the air-fuel mixture during startup. In a diesel engine, this role is particularly important when the engine is cold—such as when outside temperatures are low or when the tractor has not been run for several days. This glow plug corresponds to the original part numbers 710348R1 and 710348R2. These part numbers are used as reference points to identify the part compatible with your equipment. This is not necessarily an original manufacturer’s part, but rather a replacement part designed to meet the needs of the tractors in question.

Technical Specifications of the Glow Plug

This glow plug has the following specifications: M18 x 1.5, with an operating voltage of 0.9 V, in series configuration. These technical specifications are essential for verifying compatibility with your tractor’s engine. An incompatible thread, incorrect voltage, or improper installation can cause the preheating system to malfunction or even damage certain electrical components. Before installation, it is therefore recommended that you compare the dimensions and part number of the old glow plug with those listed here. A glow plug should be replaced while the engine is cold, and it must be removed carefully to avoid breaking the plug or damaging the thread in the cylinder head.

Compatibility with IH Case

This glow plug is compatible with several IHCase tractors, particularly older and classic agricultural series. It may be suitable for the following models:

44 Series

Case, and IH 444 tractors.

84 Series

Case IH 384 tractor.

BD Series

Possible compatibility with models 135D, 137, 238, 258, 268, 276, 288, 434, B275, B414, B450, D212, D214, D215, D217, D219, D320, D322, D323, D324, D326, D430, D432, D436, D438, D439, D440, DED3, DGD4, DLD2, and DLD3.

Classic Series

This spark plug can also be used on certain 354, 374, and 424 tractors. These compatibility listings apply to tractors known for their durability and heavy-duty use on farms. Keeping the preheating system in good condition helps extend its service life and ensures more reliable starts.

Compatible Engine Types

This glow plug is compatible with various IH engine types, including: D66, D179, BD144, D111, D74, D132, D148, BD264, BD154, and D99. Some engines may also be listed as “unknown” depending on the configuration or older technical documentation. Having these engine part numbers helps narrow down the right part. If in doubt, check the part number on the old glow plug or refer to the tractor’s technical documentation.

Why replace a faulty glow plug?

A worn-out or faulty glow plug can cause difficult starts, white smoke upon startup, an engine that runs rough when cold, or excessive strain on the battery and starter. On older tractors, a properly functioning glow plug system is particularly important for preserving the engine’s mechanical components and ensuring a quick start. Replacing the glow plug therefore improves starting reliability, reduces wear on electrical components, and maintains good performance during daily use.

Complete Your Tractor’s Maintenance

For the maintenance and outfitting of your agricultural equipment, also take advantage of hitch parts such as hitch hooks, push bars, and trailer stands. You can also find rotating warning lights, workshop carts, and tractor seats.

Original replacement part numbers and brands are listed for comparison purposes only. This does not imply that they are original parts.
