Title: ST46
Post by: Dick Carville on August 26, 2014, 03:20:15 PM
Folks I've been searching Boca Bearing for ST 46 bearings- no joy.  Anyone know the bearing numbers of the crank bearings for ST 46 (none on the ones I have) or know where they might be available.

Thanks

Dick

The Boca Bearing number is SKU#ENK-079. Says it fits all Super Tigre 46's.

The bearings for all ST G21's are the same. I use the bearings for my G21 35 on the 46.

Rear bearing is a 6001 2rs (12 x 28 x 8 ), front is 607 2rs or zz (7 x 19 x 6)  Any bearing supplier will have them cheaper than model suppliers.  Just remove the seals/shields except maybe the outer on the 607 race.

   The last time I got one (which was a LONG time ago) I went to a local bearing shop and handed it to the kid at the counter, said "I need one of these". He looked at it, turned around, walked a few steps down his giant rack of bins, grabbed it, and said "$4". The entire transaction took about 30 seconds!  Unlike the 40VF, they are completely ordinary standard sizes.

   One thing to note about shields. The shields AREN'T going to stop it leaking out the front, if it is so inclined. It's a dust/dirt shield, it's not designed to seal against any significant pressure. If it's leaking there is something causing it to pump it out, or the oil return groove is blocked or not working for some reason. I generally poked them all out, since the ST front bearing is pretty well protected from dirt by the overhanging thrust washer. For (nostalgia, at this point) combat, leave it in.

Thank you for the replays. I now see them on the  Boca site.  I've been flying mostly electric ( love it );  tried  my classic PT19  with ST 46 the other day and found the greaser to still be fun. Now I'm going to rebuild the ST 46s in my classic fleet and burn a bit of the fuel I have.

Thanks ,again
