1978 Honda CB750A Battery Box Rubbers & Mounting Parts

This battery-box selection contains mounting rubbers and one rubber-and-hardware set for the Hondamatic. It is a parts choice for the box, rather than a battery or fuse purchase. Match each rubber’s identity with its fitted position and distinguish a single rubber from the hardware set.

1978 Honda CB750A · Battery Box Rubbers Buying guide

Compare the Hondamatic battery-mount ordering quantities

The listings distinguish complete top mounting sets from loose A-type and B-type rubbers. Inspect the retained collars, bolts and washers before deciding whether the affected position needs a full mounting set.

Inspect the hardware before choosing rubber alone

Keep the collar, bolt and washer from each inspected top mount identified. Choose the rubber-only product when that is the part required, or compare the complete mounting set when its additional pieces are needed.

Keep the rubber references with their fitted positions

Rubber A references 50323-300-010 and rubber B references 50327-300-000. The other box rubber references 83618-323-000 and is sold individually. Match each existing piece independently when preparing the order.

Common questions

Does the mounting set supply both top positions?

One set lists one rubber, collar, bolt and washer. The description states two sets are used per CB750A. Compare the positions needing repair before choosing the quantity; one package is not described as containing two complete mounting sets.

Is rubber A sold with the mounting hardware?

The individual rubber A product identifies the rubber and its replacement reference. The separate mounting set explicitly includes a collar, bolt and washer as well. Choose between them by the pieces needed at the inspected top mount, rather than assuming hardware accompanies the individual rubber.

Are these listings a battery, fuse or relay package?

The products here are identified as battery-box rubbers or a rubber-and-mounting-hardware set. Their descriptions do not supply a battery, fuse or relay. Use the rubber identities and fitted box positions to choose the appropriate mounting parts.
