Ultraflex L26 Brass 33c Control Cable Clevis

The Ultraflex L26 33517N is a brass control-cable clevis for Ultraflex C22 and compatible 43C / 430-series control cables with a 1/4in-28 UNF threaded terminal. It converts the cable's threaded end into a forked pivot connection for a compatible throttle, gearbox or control lever. The L26 has a 4.8mm jaw width, a 4.8mm pin diameter and is supplied with its retaining pin assembly.

What Is This Clevis Used For?

The Ultraflex L26 threads onto the terminal of a compatible C22 or 43C-type push-pull control cable.

The forked end is positioned around a compatible control or engine lever, and the supplied pin passes through the clevis and lever to create a pivoting mechanical connection.

The L26 can be used in correctly specified:

• Throttle-control linkages
• Gearbox or shift-control linkages
• Engine-side control-cable connections
• Control-box connections requiring an L26-type clevis
• Commercial or heavy-duty installations using C22 / 43C cable
• Replacement of an existing L26 clevis with matching dimensions

The L26 is an engine-control cable accessory. It is not a mechanical steering-cable component and is not intended to connect a steering cable to an outboard tiller arm.

What Is Included?

The Ultraflex L26 is supplied with:

• One Ultraflex L26 brass clevis body
• Threaded 1/4in-28 UNF cable connection
• 4.8mm clevis pin
• Retaining clip or pin-retention component

Not included:

• Ultraflex C22 control cable
• Engine control box
• Throttle lever
• Gearbox or shift lever
• Cable mounting clamp
• Cable bracket
• Engine-specific mounting hardware
• Additional adjustment or locking hardware not forming part of the clevis
• Installation tools

This listing covers one cable-end clevis assembly.

Which Control Cables Are Compatible?

Ultraflex specifies the L26 for the:

• Ultraflex C22 control cable

The C22 is commonly identified as a:

• 43C-type control cable
• 430-series control cable
• Heavy-duty push-pull engine control cable

A non-Ultraflex 43C or 430-series cable should only be used where its terminal thread and dimensions exactly match the L26 specification.

Before ordering, confirm:

• The cable terminal has a 1/4in-28 UNF male thread
• The linkage accepts a 4.8mm-wide clevis jaw
• The lever accepts a 4.8mm-diameter pin
• The required pin-centre geometry matches the existing installation
• The cable stroke is correct for the control or engine linkage

Cable-family names alone do not guarantee compatibility where a manufacturer uses a different terminal thread or linkage geometry.

Which Lever Connections Are Compatible?

The mating throttle, shift or control lever must fit inside the L26 clevis jaw and align with the 4.8mm pin.

Check that:

• The lever thickness does not exceed the available jaw width
• The lever hole accepts a 4.8mm pin
• The pin passes through without being forced
• The clevis can pivot freely through the complete operating range
• The connection does not apply side loading to the cable rod
• The clevis does not contact a bracket or housing at either end of travel

Do not drill out the clevis or lever to force an incompatible connection.

Dimensions and Fitment

• Thread specification: 1/4in-28 UNF
• Thread type: Female
• Jaw width: 4.8mm
• Pin diameter: 4.8mm
• Stated length to pin centre: 39.7mm
• Stated depth to pin centre: 25.4mm
• Material: Brass
• Cable family: C22 / 43C / 430 series
• Joint type: Pivoting fork-and-pin connection

The dimensions should be compared with the existing cable terminal and lever before installation. A clevis with the correct thread can still be unsuitable where the jaw width, pin diameter or pin-centre position differs.

What Is the Difference Between L26 and L25?

The L26 and L25 are clevis ends for different control-cable families.

Ultraflex L26 / 33517N:

• 1/4in-28 UNF thread
• Fits Ultraflex C22 cable
• Used with compatible 43C / 430-series cables
• 4.8mm jaw width
• 4.8mm pin diameter

Ultraflex L25 / 31906D:

• 10-32 UNF thread
• Fits C2, C8 and MACHZero cables
• Intended for compatible 33C-style cable terminals

The L25 must not be substituted for the L26. Their thread sizes and intended cable families are different.

How Is the Clevis Adjusted?

The threaded clevis position determines the effective cable-end length and the neutral or idle position of the connected lever.

During adjustment:

• Thread the clevis onto the cable terminal with sufficient thread engagement
• Do not leave the clevis supported by only a few threads
• Align the clevis with the lever without forcing the cable rod sideways
• Set the cable so the control and engine linkage reach their corresponding neutral or idle positions
• Confirm the linkage reaches both operating limits without forcing the cable against its internal stops
• Secure any cable locknut or adjustment hardware specified for the installation

Do not use the clevis adjustment to compensate for an incorrectly sized cable or incompatible lever geometry.

Installation and Use

Mechanical throttle and shift controls are safety-critical. Installation should be completed by a competent marine technician.

Before installation:

• Confirm the cable is an Ultraflex C22 or compatible 43C / 430-series cable
• Check the 1/4in-28 UNF cable thread
• Inspect the cable terminal for corrosion or damaged threads
• Measure the mating lever thickness
• Check the lever-hole diameter
• Compare the pin-centre dimensions with the existing linkage
• Place the control and engine linkage in neutral or idle
• Isolate the engine starting circuit

During installation:

• Thread the L26 squarely onto the cable terminal
• Do not cross-thread the clevis
• Maintain sufficient thread engagement
• Align the clevis jaw with the mating lever
• Insert the 4.8mm pin without hammering or forcing it
• Fit the retaining component completely
• Keep the cable rod aligned with the direction of lever movement
• Adjust the cable according to the engine or control manufacturer's instructions

After installation, operate the control through its complete range with the engine switched off and confirm that:

• The clevis pivots freely
• The pin remains fully retained
• The cable rod does not bend or bind
• Neutral or idle is correctly aligned
• Forward, reverse or throttle travel is complete
• The linkage does not force either mechanical stop
• The clevis does not contact surrounding components
• There is no excessive free movement at the joint

Inspect the clevis, pin and retainer regularly. Replace the assembly if the pin, jaw or retaining component is worn, distorted or corroded.

Frequently Asked Questions

Which cable fits the Ultraflex L26?

Ultraflex specifies the L26 for the C22 control cable. The C22 is a 43C / 430-series-type cable.

What thread does the L26 use?

The L26 uses a 1/4in-28 UNF female thread.

What is the clevis jaw width?

The stated jaw width is 4.8mm.

What diameter is the supplied pin?

The stated pin diameter is 4.8mm.

Is the L26 the same as the L25?

No. The L25 has a 10-32 UNF thread for C2, C8 and MACHZero cables. The L26 has a larger 1/4in-28 UNF thread for the C22 cable.

Is the C22 cable included?

No. This listing covers the L26 clevis only.

Can the L26 be used as a steering link arm?

No. It is an engine control-cable clevis for compatible throttle or shift linkages, not a steering link arm.

Can the clevis or lever hole be drilled larger?

No. Use a clevis with the correct jaw and pin dimensions rather than modifying a safety-critical control component.
