I don't think that the bearings are available in oversize. If you really have a problem there you can always glue the bearings in with epoxy, don't use a heat hardened variant or you will never get them out :-)
Ask Ken Enya for the Bearing sizes, there are at least thre variants of this engine out there. I do also own an Enya 60X, first revision.
Ken Enya's mail address is: [email protected], Ken is one of the Brothers that owns the company and answers any questions personally and friendly.
You can even buy the bearings from him (1. quality) for not to high prices, but I really don't know if the postal services do really work nicely from there now.
In normal times you will have to wait only 2 days. (in germany longer because of our ****ty customs departments)
Don't forget to convey our best wishes and kind Regards to the japanese people down there..

Can anyone confirm my 60XF TV AL-chrome front housing is the 60III ? it's the 7101 model.  I think I've found a housing and bearings, but need to confirm its the 60III and not the 60II   I should be able to tell from a different main bearing OD ? 

big bearing approx dimensions 32mm external dia, internal approx 15mm

small bearing 22mm ext dia, 9mm internal and about 6mm wide

I can't give you exact dimensions as I don't have a vernier scale.


  Appreciate the help

I have only had trouble with old bearings that sat around WITHOUT castor oil. With castor the varnish seems to protect them, just need to get some fuel in the crankcase and let it soak first.

Correct, Enya #4 is probably what you need and about the same as OS #8.

Actually if you cannot get a new housing, then red Loc Tite may seal and keep the bearing in place. Or some epoxy. Actually this works well, but makes it hard to replace the bearing.

A new housing, front and rear bearings arrived today - thanks to a forum member who pointed me towards a evilbay seller that had what I was after.

So over the next few days, I'll look at getting the engine all put back together and fire her up again and see what happens.

Thanks to everyone for your suggestions.

.... Update - The wrong housing was sent. I now have a front housing for a Enya 60XF-4 and a main bearing to suit. This will not fit my 60XF TV CHROME. oh well... I hope I can find someone to swap parts with, or re-list on ebay.... Main difference - the internal main bearing dia (and shaft dia is 17mm on the -4, and 15mm on my unit.

But the front bearing fits my old front housing, so I hope I can get going again after I source a local bearing.

Yes, he can replace the front housing, but this will be getting expensive.
I don't think that the engine is sucking air trough the front bearing, the bearing itself isn't used to do air sealing,
that's the job of the long cylindrical part from the Crankshaft in the Housing.

I think, engine dies because the front bearing is seized up and the outer ring will be expand and finally gets stopped
because of the heat. This will stop the engine instantly.

If this where my engine I would order new bearings, they are cheap, and would try to glue in the front bearing
with some epoxy at first before I would order an new front housing. It is clear that the housing should free from oil
and debris, also the outer ring of the new bearing. It this doesn't work, one can order a new housing later..
The Main bearing has to be an open one, C3 if available, the front bearing should be a Z or 2RS...
The epoxy used shouldn't be a heat hardened type so you can remove the bearing any time as usual with heating
up the front housing. Any "5 Minutes Epoxy" will do fine, a single drop will be sufficient.

Kind Regards,

All 60XF's are Model 7101 but obviously changes were made along the way and one must have been to the crankshaft. I've just pulled apart my 60X-III and it's got a 17mm crankshaft with a 32mm diam rear bearing. You can see from the photo how the front housing on mine differs from yours because it doesn't have the "step" for the front bearing because a larger diameter casting would have been needed for the 17mm crankshaft. Seeing your front bearing is spinning in the casting then your only real option is to email Enya and see if they still have the earlier small crankshaft front housing or the later 17mm crankshaft to go with the housing you just got (so long as the crankpin fits your rod ).

If anyone's got a 60XF-II then it'd be interesting to know what size crankshaft it uses (the shape of the front housing could be a good indication).
