Multiflex K5 Jaw Clevis For 33C Control Cables

The Multiflex K5 / LM-K-5 Control Cable Clevis is a plated-steel cable-end fitting for compatible EC-033, EC-133 and universal 33C / 3300 engine control cables. Its 10-32 UNF female thread screws onto the cable’s moving threaded rod, while the 8.7mm jaw fits around a throttle, gear-shift, gearbox or other operating lever. A 7.9mm clevis pin passes through the lever to create an articulated connection and is secured using the supplied split pin.

What Is the Multiflex K5 Used For?

The K5 forms the pinned connection between the moving threaded rod of a mechanical control cable and the lever operated by that cable.

It can form part of a correctly specified:

• Gear-shift control installation
• Throttle-control installation
• Inboard engine control system
• Outboard engine control system
• Sterndrive control installation
• Gearbox selector connection
• Choke or engine-stop control using a compatible cable
• Replacement EC-033 cable installation
• Replacement EC-133 cable installation
• Compatible universal 33C / 3300 cable installation
• Industrial push-pull control linkage

When the remote control is operated, the cable rod pushes or pulls the K5. The clevis pin transfers this movement to the connected lever while allowing the joint to pivot as the lever moves through its operating arc.

What Is Included?

• 1 x Multiflex K5 / LM-K-5 plated-steel clevis body
• 1 x 7.9mm clevis pin
• 1 x split pin

Washers, cable locknuts and lever spacers are not identified as standard supplied components and should be checked against the supplied package.

Not included unless expressly stated:

• Multiflex EC-033 control cable
• Multiflex EC-133 control cable
• Remote control lever or control box
• Engine throttle lever
• Gearbox selector lever
• Cable outer-casing clamp
• Structural support bracket
• Cable locknut
• Ball joint
• Cable-end pivot
• A second clevis
• Other engine-specific linkage fittings

Which Control Cables Are Compatible?

• Multiflex EC-033
• Multiflex EC-133
• Compatible universal 3300 / 33C control cables

The selected cable must have a compatible 10-32 UNF male threaded moving end. Cross-brand compatibility also depends on the jaw width, pin diameter, lever thickness, linkage geometry and operating load.

Is the K5 Suitable for Universal 33C / 3300 Cables?

Yes. The K5 is designed for compatible 330 / 3300 / 33C-series engine control cables.

Before ordering, confirm:

• 10-32 UNF male cable-end thread
• Required clevis jaw width
• Operating-lever thickness
• 7.9mm pin requirement
• Operating-lever hole diameter
• Required articulation
• Cable travel
• Operating load
• Available installation clearance

A matching cable-end thread alone does not guarantee complete compatibility.

Is the Multiflex EEC-133 Edge Cable Compatible?

The published K5 product data specifically list EC-033 and EC-133. They do not specifically identify the EEC-133 Edge cable.

Although EEC-133 uses a 10-32 UNF threaded end, compatibility should be verified before it is described as a direct K5 application.

What Does the 8.7mm Jaw Width Mean?

The operating lever or linkage tab fits between the K5 clevis jaws.

• Published internal jaw width: 8.7mm
• Approximate imperial width: 0.34in

The lever must fit inside the jaw, accept the clevis pin and articulate without binding or excessive side clearance.

What Thread Does the K5 Use?

• Female thread: 10-32 UNF
• Alternative description: 3/16in UNF

The female thread screws onto the male threaded moving rod of a compatible control cable.

What Is the K5 Clevis Pin Diameter?

• Clevis pin diameter: 7.9mm
• Approximate imperial diameter: 5/16in

Check the physical clevis pin and operating-lever hole before drilling or modifying the linkage.

How Does the K5 Clevis Work?

1. Screw the K5 onto the control cable’s 10-32 UNF threaded moving rod.
2. Position the operating lever between the clevis jaws.
3. Align the lever hole with the clevis pin holes.
4. Pass the 7.9mm pin through both clevis jaws and the operating lever.
5. Secure the pin using the supplied split pin.
6. Adjust the cable to the correct neutral, idle or rest position.
7. Check that the clevis pivots freely throughout the lever’s movement.

Which Ultraflex Clevis Is Equivalent?

The closest Ultraflex functional equivalent is:

• Ultraflex L25
• Product code: 4-L25
• Manufacturer part number: 31906D
• Thread: 10-32 UNF
• Material: Plated steel

Is the Ultraflex L25 a Direct Replacement for the K5?

Multiflex K5 / LM-K-5

• Jaw width: 8.7mm
• Pin diameter: 7.9mm
• Thread: 10-32 UNF
• Material: Plated steel

Ultraflex L25 / 31906D

• Jaw width: 7.1mm
• Pin diameter: 6.4mm
• Thread: 10-32 UNF
• Material: Plated steel

The two products perform the same general function but require different operating-lever widths and pin-hole diameters. Confirm the lever dimensions before substitution.

Does the K5 Secure the Cable Outer Casing?

No. The K5 connects the moving cable rod to the operating lever.

The stationary cable outer casing must be secured separately using:

• Multiflex K3 cable clamp
• A remote-control-box retaining arrangement
• An engine-side support bracket
• Another approved control cable clamp

How Does the K5 Differ From the Multiflex K10?

Multiflex K5

• Forked clevis-jaw design
• Straddles the operating lever
• Uses a transverse 7.9mm clevis pin
• Plated-steel construction

Multiflex K10

• Cylindrical pivot or swivel-end design
• Uses a single pivot-pin connection
• Connects to the side of an operating lever
• Stainless-steel construction

Select the connection type that matches the operating-lever geometry.

Does the K5 Hold One or Two Control Cables?

The K5 connects one control cable to one operating lever. Separate shift and throttle cables may require one clevis for each mechanism.

Is the Operating Lever Included?

No. The K5 is the cable-end clevis fitting only. The control cable, operating lever and cable-support components are supplied separately.

Is the K5 Plated Steel?

Yes. The K5 is manufactured from plated steel.

The steel grade, plating material, plating thickness and formal corrosion-test specification are not published.

What Are the K5 Dimensions?

• Published jaw width: 8.7mm
• Published clevis pin diameter: 7.9mm

The overall clevis length, body width, threaded-hole depth, pin length, maximum lever thickness and maximum articulation angle are not published in the reviewed K5 product data.

Can the K5 Be Used with Steering Cables?

No. The K5 is intended for mechanical engine control cables, including compatible shift and throttle cables.

It is not intended for rotary steering cables, rack-and-pinion steering cables, hydraulic steering hoses or steering link arms.

Is a Maximum Working Load Published?

No maximum working load or proof load is stated. Select the K5 according to the control cable, operating lever, engine or gearbox requirements and complete linkage geometry.

• Do not cross-thread the clevis
• Maintain sufficient cable-thread engagement
• Position the lever centrally between the clevis jaws
• Insert the clevis pin fully through both jaws and the lever
• Install the split pin completely
• Ensure the clevis articulates freely
• Align the control cable to avoid side loading
• Secure the cable outer casing separately
• Maintain the cable manufacturer’s minimum bend radius
• Operate the control through its complete range
• Confirm positive gear positions where used for shifting
