- Pack of 1 piece.
Use Cases
This feed-bar shaft pin is suitable for industrial sewing applications involving:
- Garment manufacturing
- Tailor shops
- Industrial sewing-machine maintenance
- Woven-fabric production
- Knit-fabric production
- Light and medium-weight garment production
- Heavy-duty sewing applications
- Feed-mechanism repair and rebuilding
Benefits
Maintains Feed-Bar Movement
The pin acts as a pivot point within the feed mechanism, allowing the feed bar to move through its intended operating path.
Helps Maintain Feed Accuracy
A worn or damaged pivot pin can introduce unwanted movement into the feed mechanism. A properly matched replacement helps maintain stable feed-bar positioning.
Hardened Construction
The hardened steel construction is designed to withstand repeated mechanical loading from the feed mechanism during continuous industrial sewing.
Smooth Pivot Action
The finished outer surface supports smooth interaction with the mating feed-bar components and helps reduce unnecessary friction.
Useful for Machine Overhauls
The component is suitable for replacing a worn feed-bar pivot during routine maintenance or a more extensive feed-mechanism rebuild.
Machine Compatibility
Primary compatibility: Typical GC6150, GC6150M, GC6150H and GC6-1 series high-speed single-needle lockstitch machines.
Additional stated compatibility: Jack, Juki, Singer, Brother, Zoje and other compatible 8700/6150-style single-needle industrial lockstitch machines.
Part Number: 36T4-001A2 / 36T4001A2 / 36T4-001
For machines outside the primary Typical application, verify the existing part number and physical dimensions before ordering.

How To Use
First, switch off the sewing machine and disconnect the power before accessing the feed mechanism.
Next, remove the necessary machine covers and inspect the existing feed-bar pin, rocker mechanism and mating surfaces for wear or scoring.
Then, remove the worn pin and install the replacement in the original feed-bar pivot position, ensuring that the mating components are correctly aligned and adequately lubricated according to the machine’s service procedure.
Finally, rotate the machine manually through the feed cycle and check that the feed bar and feed dog move smoothly without excessive side play before testing the machine at operating speed.
FAQs
What is a feed bar shaft pin used for?
The feed bar shaft pin serves as a pivot point for the feed-bar mechanism. It allows the feed bar to move through its required motion while maintaining its relationship with the feed dog and other feed components.
What machines use the 36T4-001A2 feed bar pin?
The supplied application identifies the part for Typical GC6150, GC6150M, GC6150H and GC6-1 series industrial lockstitch machines. It is also stated for compatible 8700/6150-style machines from other brands, but the physical fit should be verified before ordering.
What happens when a feed bar pin becomes worn?
A worn pivot pin can create excessive play in the feed mechanism. That movement can affect feed-dog positioning and contribute to inconsistent material feeding or irregular stitch spacing.
Can a worn feed bar pin cause uneven stitch length?
It can contribute to inconsistent feeding when excessive wear allows unwanted movement in the feed mechanism. However, uneven stitch length can also result from feed-dog adjustment, timing, presser-foot pressure or other worn components, so the complete feed system should be inspected.
How can I tell if the feed bar shaft pin needs replacement?
Inspect the pin and mating components for scoring, visible wear or excessive clearance. Unusual movement at the feed-bar pivot, inconsistent feeding or abnormal mechanical noise can also indicate that the pivot area needs inspection.
Is this pin suitable for heavy-duty sewing?
Yes. The supplied specification identifies hardened tool-steel construction for repeated feed-mechanism loading. Suitability for a particular heavy-duty machine still depends on matching the correct pin dimensions and machine configuration.
Should the feed bar pin be lubricated?
Yes, lubrication should follow the sewing machine’s prescribed maintenance procedure. Proper lubrication at pivoting surfaces helps control friction and wear, while excessive lubricant can attract lint and dust into the feed mechanism.
Can I install this pin without adjusting the feed mechanism?
The pin itself is a replacement mechanical component, but the feed mechanism should be checked after installation. If the old pin had significant wear, replacing it can change the amount of play in the mechanism, making inspection and adjustment important.
Can I use this on any 8700-style lockstitch machine?
No. “8700 style” does not guarantee identical parts across every manufacturer or revision. Compare 36T4-001A2 and the physical dimensions, mounting arrangement and mating components before purchasing for a non-Typical machine.
