1979 Honda CB750L Instrument Seals & Hardware

Check the instruments actually fitted to the Limited before ordering small hardware or seals. The cap-nut set serves stock-type speedometer and tachometer mounts, while the internal rubber seal is specified for stock-type ND gauges. Aftermarket instruments can require entirely different mounting and sealing pieces.

1979 Honda CB750L Limited · Instrument Seals & Hardware Buying guide

Identify the gauge before ordering small parts

The mounting nuts and internal rubber seal serve different locations. Compare instrument make, mounting studs and the damaged seal rather than treating these items as a universal gauge repair package.

Match the original mounting arrangement

The cap-nut set is intended for stock OEM-type instruments. Check the studs and bracket before ordering if the gauges have been swapped. Four nuts in the package does not establish the hardware required by a custom mounting arrangement.

Assess gauge condition before opening

An internal seal belongs inside the gauge, not under its bracket. Confirm the ND instrument application and compare the seal being replaced. If opening the instrument requires specialist restoration work, plan that service before buying small internal pieces.

Buying questions

How many cap nuts are supplied?

The package contains four. They are described for stock-type speedometer and tachometer mounting, so compare the actual studs if instruments or brackets have changed.

Will the internal seal fit any aftermarket gauge?

No universal application is established. It is specified for stock-type Honda CB750 ND gauges; confirm the instrument make and internal seal arrangement before ordering.

Is the rubber seal an external mounting damper?

It is described as an internal gauge seal. Identify the damaged part’s location first so an internal sealing piece is not ordered for an external instrument mount.

Not sure which part you need?

Send your model and year, plus photos of your existing part and any changes to the original setup.
