Belt tensioner pully bearings

Post by Black Lightning on Mon Aug 12, 2013 9:25 pm

So, the nice man at Kamloops HD said my bearings were on the way out and the local bearing house didn't have any. I suspect they didn't have any with that specific number because the bearing house in Williams Lake had all kinds that would fit. He didn't want to order it from his suppliers because he thinks they will send the whole tensioner pulley with bearings which will cost lots.

Bearing part number is NTN 6203LAX30. NTN denies all knowledge of such a bearing and it turns out to be a special bearing also used for tensioner pulleys on some Fords and Dodge products as well, not in their main catalogue. Looking at the specifications for 6203 bearings suggests that any 6203 bearing will fit. You need two sealed units.

Apparently some tensioner pulleys had a single 5203, (thickness 17.5mm. same bore diameter and OD as the 6203), sealed bearing. This would require modification to the pulley to make 6203 bearings fit. The dual 6203 bearing version, (total thickness 24mm), will handle more load than the double row 5203 bearing, (thus should last longer).

I'll update this later when I  know how it turns out.

Except that McMaster-Carr won't ship me stuff. The local bearing house in Williams Lake had the bearings in stock. 15 bucks for the pair.

OK, it's all back together. The retaining ring was a rectal discomfort, (wtf is wrong with circlips anyway?). I had to use a little heat to loosen the bearings so they would push out. A 1 1/8th socket will serve in a vice to push them back in again and a 1 1/2 inch socket works as an anvil when pushing them out. I drove them out with a brass hammer. So all it cost me was a trip to town and $15.00 plus a little time, (and some rather gratuitously foul language).

By the way, The exploded drawing of the belt tensioner assembly doesn't break down the bearings and pulley. I suspect that means that neither HD nor EBR will sell you just the bearings.
