    Starter Motor bearing and seal.

    Anyone replaced them? If so where did you get them?...Ta

    If you are talking about part # 8 on this drawing then it is still available and it's just an O-ring you can get from a proper Metric O-ring kit more than likely but you could order it from JD at Hordpower or probably if you have a local bike shop or honda stealership they can get it ordered for you if they don't have it in stock. Here is the nomenclature.


    O-RING (24.4X3.1)

    90 Hawk GT (color as to yet be determined) - Still on the shelf in crates

      I don't see any bearings listed for the assembly though so maybe there are just bushings inside?

        Like rpcraft says I cannot see a bearing listed, I have had a couple of starter motors in bits but I cannot remember what bearing was fitted, there must be an oil seal in there too, all I do is take the brushes out, clean the motor out with brake cleaner and clean the com up with fine wet/dry and put it back together and a drop of oil on the rear bush. What ever the the bearing I cannot see it will be worn out.

          Exactly! The bearing and seal are not numbered/listed (ie not service items). They ARE shown however to the right of the o-ring past the left cover. I have the motor stripped and the bearing and seal LOOK light standard items. I could measure them up and source them. But if someone has already done it...would help.

            If you look closely at the bearing it should have a number on it and I'm about 99 % sure you can replace it with an identically numbered bearing from a known good brand (Timken is a known good brand). if you can not find a number on it then earch by size and bearing type (radial, sealed, etc etc).

            Here is the Timken site for bearings. https://www.timken.com/engineering-t...earing-search/

            The seal may be a little more difficult but you can also measure it with the ID X OD X Width you can do a little scrounging on the Timken website as well. Usually I start with the description of oil seal and that often gets me in the right parts type and then some cheap calipers will be your friend on the measurements. Just as a point of reference, if you were looking for one of the dust seals for the swingarm and Honda did not list it You could source from Timken a Dust Seal based on OIL Seal (OR maybe dust seal) and then 22 x 35 x 7. The Timken site has a tool that lets you search by size and type, and you will have to do some research to figure out if you need Nitrile (MOre than likely) or Viton, etc etc.
            Here is a link to the Timken site for seals.

            With a little reading you can figure it out. One other resource you can maybe try is to see if All balls has a rebuild kit that may include it. Sometimes they do for starters of various bikes.

              If there's a bearing in there, it is a standard bearing, available at your local bearing house.
              Honda doesn't make bearings. They buy them. So can you.
              Seals too.

                I'm sure I can source both. The bearing has been a point of failure before with me on a VF750S. What I don't understand is why Honda did not think to prt number them and list as an item.

                  Called 'service as assembly"
                  Honda won't make much money selling $4 bearings. A $4 part number COSTS Honda every time they sell one.
                  Honda makes BANK selling $120 "assemblies"

                    I know Honda does not make a great many parts made by other companies but Honda (for instance) list 5x25 screw 93500050250G for 1 euro so why not caged roller bearings for maybe 15 euros?
