The Singer 700 Series was a leap forward in home sewing innovation. These machines were part of the Touch & Sew lineup that dominated the late 1960s and early 1970s, introducing features such as automatic bobbin winding in place and plastic gear-driven internals.
While revolutionary at the time, these machines are now over 50 years old — and they’re showing their age. Whether you're working on a 737, 750, 755, 756, or 758, this collection includes the specific parts you need to keep your Singer 700 series running reliably.
No generic parts. No guesswork. Just time-tested, Singer-specific replacements sourced for the exact quirks of this model group.
What’s Included in This Collection
This parts collection is curated specifically for the Singer Models 737, 750, 755, 756, and 758 — covering everything from cosmetic fixes to critical internal replacements. Every part is selected based on known wear points in the 700-series machines and backed by compatibility notes.
Included Part Types:
-
Bobbin Cases & Hooks: These models use a unique internal bobbin winding system with drop-in bobbin holders. We carry both bobbin cases and rotary hooks matched to the 700 series setup.
-
Drive Gears & Cam Stacks: One of the most common failure points in these machines is stripped plastic gears. We offer replacement internal gears (vertical gear, horizontal gear, cam stack gear) for the motor drive, stitch selector, and feed mechanisms.
-
Power Cords & Foot Pedals: Replace cracked, shorted, or worn foot controllers with safe, plug-matched replacements. These are compatible with the multi-prong port specific to Touch & Sew series Singers.
-
Tension Assemblies: Full replacement tension units and springs to fix upper thread looping or weak stitch formation.
-
Light Bulbs: Exact wattage and socket-style replacement bulbs that fit behind the faceplate and under the top panel.
-
Presser Feet & Shanks
Compatible feet for general sewing, zigzag, buttonholes, and darning. Most 700 series machines use a slant shank; we stock both original and aftermarket styles.
-
Thread Guides, Springs, and Bobbin Winders: Tiny parts, often overlooked, that make all the difference in smooth operation.
Each listing includes the exact models it supports, allowing you to order with confidence.
Singer 700 Series Machines Covered
Let’s break down what’s included in the “Singer Model 700s” category:
Singer 737
Basic zigzag machine with front panel dials and top thread guides. Uses many of the same internal parts as the 758.
Singer 750
One of the most feature-rich Touch & Sew models. Came with a built-in cam stack, drop-in bobbin system, and complete stitch width control. Many internal gears are prone to wear and need replacement.
Singer 755
Similar to the 750 but with fewer decorative stitches. Uses the same internal gear train, foot control, and bobbin assembly.
Singer 756
Straight-stitch and zigzag capable, includes a multi-point feed system. Compatible with most replacement gears, belts, and light bulbs in this collection.
Singer 758
One of the highest-end Touch & Sew models. Featured advanced buttonhole functionality and needle position control. Requires specific internal gear sizes, which are included in this collection.
These machines share a surprising number of interchangeable components, but also have critical differences in terms of gear tooth count, motor mounts, and bobbin drive assemblies. That’s why this collection clearly notes the exact models supported in every listing.
Common Repairs for Singer 700 Series Machines
This series of machines is built to last — but a few components are known trouble spots. Here’s what tends to fail first, and what to fix it with:
Plastic Gears
The internal gears used in the bobbin winding system and drive train tend to crack or strip over time. We carry upgraded replacements designed to withstand modern use without deforming.
Bobbin Cases
Over-tightened tension screws or accidental drops can warp the case or break the retaining clips. A new case restores proper thread control and snap-in fit.
Light Bulbs
Many original bulbs were incandescent and have long since burned out. We carry both original-style replacements and LED upgrades (if preferred), rated for your Singer’s voltage.
Power Cord & Foot Pedal
Touch & Sew machines use a proprietary 3-prong power port. Our replacements come pre-wired for safety and correct polarity — no adapters needed.
Cam Stack Issues
These machines rely on internal cams to form decorative stitches. If your stitch selector slips or won’t engage, it’s likely due to a worn cam stack or a cracked gear underneath.
Why "Universal" Parts Don’t Work for the 700 Series
Many repair shops and marketplaces offer “Singer-style” parts that claim broad compatibility. Here’s why you should avoid them:
-
Incorrect bobbin fit can throw off thread delivery and tension
-
Wrong hook shape can damage the needle or jam the race
-
Mismatched gears may install but grind down quickly under motor pressure
-
Wrong voltage or plug type can destroy your foot pedal or short the circuit
That’s why this collection includes only matched, model-specific parts for the 737, 750, 755, 756, and 758 — not just generic lookalikes.
Installation Tips for 700-Series Parts
Most of these parts can be installed with a small screwdriver and a bit of care. Here are a few reminders before you start:
-
Unplug the machine before opening the case or touching any electrical components.
-
When replacing gears, remove all traces of old grease and use new lubricant to avoid binding.
-
Replacing the bobbin case? Make sure to reset thread tension using test stitches after install.
-
Installing a new foot pedal? Ensure the plug is fully seated — Touch & Sew plugs can feel stiff initially.
-
For cam stack replacements, work slowly and take photos before disassembly.
