6203 C3 crankshaft bearing for rebuilding e50 (one speed) engines on any puch moped. also one of the bearings for peugeot engines, derbi flat reed and piston port/pyramid reed magneto side!!!!! tomos A35/A55 (oem#035070), garelli NOI +VIP (check NOI first! see note below), morini m1/m01/M02, yamaha QT50 (both sides), puch ZA50 output shaft and others like solex !!! ++ 1 of 2 honda nu50 transmission bearings (6202 is the other).

A total rebuild of your E50 will require 4 bearings - 3 of these and one 6203 NR. see here for more puch bearing sets

for garelli NOI you need 2 of these for just the crank or 4 for a full rebuild, take note though some garelli noi use a 16003 bearing and some use a 6203 apparently...check first !

brand wise we ONLY carry the highest quality c3 bearings! You will get either NSK, SKF, NTN or ZKL. we do not carry generic unmarked crappy bearings!

for garelli VIP you need 2 of these for the crank bearings, plus one more for the driveshaft if you like

take note! pre-1986 tomos A3 engines use L17 bearings NOT 6203!

bearings measurements:

17mm ID
40mm OD
12mm wide

5 of 5 How I fit them November 22, 2024
taco eater : colby ainsworth from Elk Grove, CA United States  
With an over, a freezer, a block of wood, an old bearing, rod, and a deadblow hammer. The old bearings are a perfect fit rather than a socket.

These look like good quality.

YO!! TOMOS A3 PEOPLEZ! there are TWO different versions of your motor! the EARLY VERSION (ie silver covers and some very early black covers) use L17A CRANK BEARINGS! these ones (6203  C3) ONLY WORK FOR THE LATE VERSIONS!! (ie, very late-model black cases) MEASURE YOUR CASES BRUH!

1 of 5 Not for Tomos A3 September 4, 2020
taco eater : Kevin Edwards from omaha, NE United States  
If you search for A3 crankshaft bearings the results all are 6203 C3. Which is the wrong size bearings The A3 uses L17 bearings on the crankshaft, 2 mm thinner

2 of 5 I don't like 'em October 4, 2014
taco eater : Anonymous Person from Colorado  
Couple didn't spin well. Vinegar made them rust. Maybe I don't know what I'm doing, but this is the first time I've had issue with bearings like this.
