On the inside front cover of the CX500 starter there is an oil seal. It is not shown/listed in any fiche that I pull up from various sites. It's the internal oil seal I need a number for, not the "O"-ring forward of it which is 91312-MG7-003.



The starter is Mitsuba SM-228



Thanks!

I had one of these fail and the starter was full of oil which made the thing

a bit sluggish.

Took me a while to find the cause, never knew they had internal oil seals until then.



No idea of the dimensions but I'd measure the shaft to get the inside diameter

and round it down to the nearest whole figure

If it measures say 11.5mm, I'd look for an 11mm ID type for instance

The old one or casing will give the outer and thickness dimensions

then you just go to an oil seal dealer and order one.

Most stores that specialize in bearings also have various sizes and types of seals. Since bearings actually originated as metric in size chances are we could find replacements fo almost anything if we looked hard enugh.

The 'O' rings for inside the starter motor housing are sized 60 x 1.4 mm {Honda} with a commercial equivalent of 60 x 1.5 mm.. {Courtesy Oz C.X. site}. Hope this helps.

The seal should have it's size coded on it.

Just realised I had a spare sitting beside my PC

so whipped the end off and measured it up

The shaft is 13.5mm so I reckon a 13mm ID seal will be good

OD is 24mm and the depth near as dammit is 6mm

Dont lose the circlip! those buggers have a tendency to fly

off down the street.



So, I'd be looking for an 13 X 24 X 6mm oil seal

I just checked simply bearings here in the Uk and they have Nitrile ones

for £5.20 which I find a bit pricey but at least if I can find em easily

then hopefully so can you

While I'm rantin on.......

The two long screws often suffer and get chewed up so if anyones looking for shiny new ones

you'll need ones 110 mm long with a standard metric 5mm thread and Pan heads

Thanks Gents!.... all good info.



I found several places that may have complete 2-brush rebuild kits (seal, washer, brushes, mounting plate etc). Small motor repair outfits. And it looks like the seal alone will not be hard to get.



Oh Reg.... it's not everyone who has a starter motor right next to the PC. That's special.



I myself have only a crusty water transfer pipe next to the keyboard. However, not long ago I had two cyl heads boiling on the stove. They were then dried in the oven. The house has been well aired out as my wife will be home from work in an hour.







BTW there appears to be a felt oiler in the Mitsuba starter's aft cover behind the bushing. Thought it was fuzz for a second.

14x24x6 is confirmed. Not that I doubted you "magilla" but that is the seal that came with a rebuild kit which I received today.



Thanks to All,
