Steel Wire Rope Protection Cover for Yamaha SS12-72MM Feeder

1. What is the KHJ-MC28B-00?

It is a protective metal cover designed to shield the internal steel wire rope mechanism inside Yamaha’s SS12-72MM tape feeders. It prevents physical damage, contamination, and misrouting of the cable that controls the feeder’s motion.

2. Which Yamaha feeders use this part?

The KHJ-MC28B-00 is specifically used in SS12-type feeders with a 72mm tape width, commonly found in Yamaha high-speed SMT machines.

3. What does this cover protect?

It protects components such as:

The steel wire rope assembly (KHJ-MC25A-00)
The return spring (KHJ-MC26D-00)
The pulley guide (KHJ-MC23B-00)
These components form the internal motion control system that drives tape feeding.

4. What materials is it made from?

It is typically made from stainless steel or nickel-plated spring steel, offering corrosion resistance, rigidity, and durability for use in high-speed production environments.

5. What are signs that the protection cover needs replacement?

Bent, deformed, or broken cover
Rattling or loose fit
Wire rope exposure or abnormal wear
During a feeder overhaul or preventive maintenance

6. Is it user-replaceable?

Yes. It can be replaced by trained personnel. Simply remove the cover using appropriate tools (usually a small screwdriver), inspect internal parts, and install the new cover with original mounting screws.

7. Should I replace other parts along with the cover?

Yes, it's recommended to check and replace related components if worn:

KHJ-MC25A-00 – Steel wire rope
KHJ-MC26D-00 – Spring
KHJ-MC23B-00 – Pulley bracket
Also check alignment and smoothness of the feeder mechanism.

8. How often should it be inspected or maintained?

Visual inspection: Every 1–3 months, or during each feeder service cycle
Replace if cracked, bent, or interfering with cable movement
Clean regularly with lint-free cloth; avoid solvents unless specified

9. Does it affect feeding accuracy?

Yes. A damaged or loose cover may interfere with the wire rope's movement, leading to misfeeds, jerky tape motion, or component misplacement on the PCB.

10. Where can I buy KHJ-MC28B-00?

From authorized Yamaha SMT parts distributors or official Yamaha service centers. Use only genuine OEM parts for reliable performance and compatibility.
