rear sprocket
« on: February 27, 2013, 01:31:10 PM »
when replacing the rear sprocket/drum, is the bearing a press fit(to swap into the new unit)? any special procedure?

Look on youtube for  singh5g  videos, I believe he has one posted specifically for the sprocket, a search on youtube should get you there.

Yes, press fit.  You'll need to press it out.  For the install you can put it in the freezer and maybe put the sprocket/drum in the oven at 250 if you like to make it easier to put it in.

My mechanic destroyed one when replacing it, I guess it didn't want to come out nicely.  It was a standard size though since they just picked one up in town.

These just came up in another thread:
Sprocket/drum x 1
   6005-2RS/C3
Rear wheel x 2
   6203-2RS/C3
I'm not sure if there's any way to remove the bearing from the rear sprocket without ruining it.  There's a seal too but I don't have the spec for that.  If I get it I'll post it.

Yes,  I believe so.  The sprocket/drum may be different between the C5/B5/G5, maybe not, but I'm pretty sure all the bearings are the same.  Buying them locally gives you an advantage here.  You can either remove them and take them with you or return them if you got the wrong ones.  Also, I'm betting you can get better quality at a bearing shop than the Indan OEM ones.

Perhaps be careful with that one. :-\

Rear wheel bearing failed, axle nut over torqued at factory.
Was replaced by a bearing from german top quality. Went out too: being too good.
Replaced by standard part from india. No issues since.

Rear Wheel Bearing: 6005 C3, part number 145553.

As my dealer says: an Enfield likes it loose. So do I.

Possibly, yes :)  When things are generally loose you don't necessarily want to put one tight component in there.

I figure that's part of why C3 bearings are spec'd.  C3 means there's a little more than normal clearance.  I suspect something like an extended freeway run that keeps the wheels spinning fast under load could heat them up, hence the extra clearance to compensate for things getting hot and tightening up a bit.

Bearing numbers like 6002, 6203 etc are based on a worldwide industrial standard number system.
SKF, FAG, New Departure, Timken or Fred Flintstone Bearing Company all use these numbers to define the basic bearing type and size.
For a good explanation of how bearing numbers work, follow this link

The grease seal is 25 x 40 x 7 mm (ID x OD x Width).

The bearing 6203 RS1 (rubber seal single sided) = 17 mm ID x 40 mm OD x 12 mm Width.

6  = Type code = single row deep groove ball bearing
2  = light
03 = bore size 17 mm

I do not remember the details of bearing when I had opened my G5 rear wheel.  I got the specs from RE catalogue.

 It would be best to confirm them if someone is going to open the wheel, because things can change without notice or catalog may be different from actual - though it would be prettly close

I believe C3 is the internal radial clearance in the bearing - see link below

http://www.bearingworks.com/technical_data/internal_clearance.php

PS - Just saw that a few posts above, you have mentioned 2RS - perhaps two sided seal it is !
