2PCS 37936 0.014" Offset 1.328" L Bellhousing Dowel Pin

Offset Bellhousing Dowel Pins

This pair of offset bellhousing dowel pins provides alignment correction between the engine block and transmission bellhousing, referencing part number 37936.

Overview

These precision-machined dowel pins help correct centerline misalignment when mating transmissions to engine blocks. Designed for critical powertrain setups, these dowel pins resolve issues related to pilot bearing wear and clutch release problems. Professional engine builders use these dowel pins to ensure precise concentricity of the input shaft.

Built For Performance

• Precision ground from high-tensile steel to resist shear forces and wear
• Features a 0.014-inch offset to allow fine-tuning of transmission alignment
• Measures 1.328 inches in length for secure engagement in the block
• Set screws included to lock the pins in the desired radial position

On-The-Job Use

• Aligning manual transmission bellhousings during performance engine swaps
• Correcting input shaft angle to prevent premature clutch and pilot bearing failure
• Verifying concentricity on high-performance racing drivetrains

Specs At A Glance

Good To Know

Q: Why is bellhousing alignment important? A: Proper alignment ensures the transmission input shaft sits dead-center in the pilot bearing, preventing clutch chatter and gear wear.

Q: How is the offset adjusted during installation? A: The offset dowel pins are rotated in their bores until a dial indicator shows the bellhousing is concentric with the crankshaft.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
