Jeep 4.0 Bellhousing Bolt Size

The Jeep 4.0 bellhousing bolt size is a critical factor in the proper installation and operation of your Jeeps engine. It is important to select the correct size for your application to ensure that the bolts are properly tightened and will not loosen over time. There are two different specifications for bellhousing bolts, OEM specifications, and aftermarket specifications.

OEM Specs

The OEM specification for bellhousing bolts is typically M8 x 1.25 – 16mm long with a 6mm hex head. These bolts are usually made of high quality steel and are designed to be durable and reliable in extreme conditions. The OEM specification also includes a locking washer to ensure that the bolt does not loosen over time due to vibration or other external forces.

Aftermarket Specs

The aftermarket specification for bellhousing bolts varies depending on the manufacturer, but typically consists of an M6 x 1.25 – 16mm long with a 6mm socket head cap screw (SHCS). Aftermarket bolts are usually made of lower quality steel than OEM bolts and may not be as reliable in extreme conditions or as durable over time. In addition, aftermarket bolts do not include a locking washer which could cause them to loosen over time due to vibration or other external forces.

Overall, it is important to make sure you select the correct size when installing the Jeep 4.0 bellhousing bolt size on your vehicle in order to ensure proper operation and reliability over time. Both OEM specs and aftermarket specs should be considered when selecting the right bolt size for your application, as each has its own pros and cons depending on your specific needs.

Jeep 4.0 Bellhousing Bolt Size

When it comes to the Jeep 4.0 bellhousing, having the correct size of bolts is essential for a reliable and secure installation. To ensure that the bellhousing is properly installed, the bolts used must be of the correct type and size.

Bolts Used in Jeep 4.0 Bellhousing

The most common type of bolt used for the Jeep 4.0 bellhousing is an SAE Grade 5 or 8 bolt with either a fine or coarse thread pitch. The number of bolts used will vary depending on the specific model of Jeep; however, most models will require a minimum of 7 to 10 bolts.

Type of Bolts Used

The type of bolt required will depend on your specific Jeep model; however, typically an SAE Grade 5 or 8 bolt with either a fine or coarse thread pitch is recommended for installation. In some cases, depending on age and condition, an SAE Grade 2 or 3 bolt may be required as well.

Measurements of Bolts Used

When selecting the right size bolts for your Jeep 4.0 bellhousing, you need to consider several factors: thread pitch, length and diameter (or head size). The thread pitch should match the existing threads on your bellhousing; which can usually be determined by closely inspecting the existing threads on each hole in your bellhousing. Typically, most common pitches are either 0.25-inch for fine-threaded bolts or 0.375-inch for coarse-threaded bolts; however this can vary depending on your specific model and year Jeep vehicle. The diameter (or head size) should match that of the existing holes in your bellhousing as well; generally speaking this would typically be 1/4 inch for fine-threaded bolts or 5/16 inch for coarse-threaded bolts but again this can vary depending on model and year of vehicle so take care to get accurate measurements prior to purchasing any replacement parts! Finally, you need to consider how long each bolt should be based on the depth of each hole in your bellhousing – again you’ll need to measure accurately here as too short a bolt may not secure properly whereas too long a bolt could damage other components within the engine bay!
