1979 Honda CB750F · Fork Springs & Seals Buying guide

Match service parts to the fork assembly fitted

Fork sealing, spring replacement and internal hardware are separate parts choices. Identify the front end fitted to the 1979 CB750F and compare its components before ordering, especially where a later fork assembly may have replaced the original.

Parts to consider

Fork oil-seal setJapanese-made set 27-1007 explicitly lists the 1979–80 CB750F. Its dimensions and later-F alternative are compared below.View part

Two-piece fork dust-seal setJapanese-made dust-seal set 27-1049 supplies two pieces and lists the 1979–80 CB750F.View part

Progressive front-fork spring setSpring set 27-1078 lists the 1979–80 CB750F. Review its supplied fitting pieces below when planning the replacement.View part

Identify small hardware by position and reference

Stopper-ring pack 73-0940 supplies two metal rings that fit above the fork seals, replacing 51447-KL4-951. Copper washer set 15-0045 supplies two 8 × 13 × 1.5 mm washers referencing 90544-283-000 and two 6 × 10 × 1 mm washers referencing 90543-273-000. Match the required pieces with the removed parts and applicable fork information.

Check the oil-lock piece independently

The genuine Honda oil-lock piece is 51432-371-003 and is sold individually. Its listing includes the 1979 CB750F and specifically asks buyers to compare the old part, fork diagram and OEM number. Keep that reference check separate from choosing an oil seal by dimensions.

Questions before ordering

Do the progressive springs require a separate spacer-and-washer purchase?

Set 27-1078 is described as two progressive springs with the required spacers and washers included. Check those supplied pieces against the identified fork assembly before adding more fitting parts; the listed CB750F application is 1979–80.

Which seal listing distinguishes the 1979–80 F from the later 1981–82 F?

Set 27-1007 lists the 1979–80 CB750F and gives 35 × 48 × 10.5 / 11 mm dimensions. Set 27-1028 instead lists the 1981–82 F and gives 37 × 50 × 11 mm. Compare the fitted fork assembly and seal dimensions rather than selecting from a broad CB750 or DOHC description alone.
