Spindle bearings

[68 raider 12 3]

I have a 68 raider 12 and one of the bearings in the center spindle of the mowing deck needs to be replaced. I can't seem to find the exact bearing needed to replace it. Iv gotten several from eBay but the center Bore isn't wide enough for the shaft go through. Thanks.

Question:  Does the  spindle shaft have a KEYWAY slot in the top of it?  If so, that means the top of the shaft is 3/4" diameter.  Later model spindles do NOT use the Keyway slot and the shaft steps down from 3/4" dia to 5/8".

I don't have the answer that you seek, but some one should be along soon.

Do you have all the bearing dimensions? I have 3/4" ID X 1 .50" OD X .5" Width bearings on stock.

Over the years WH used a lot of different spindles.  .  When WH wanted bearing for 3/4 shaft they are bearing number.62032rs-12   3/4" ID 40 mm OD (standard bearings are measured in mm.)  Later they switched spindle shafts to use more readily available (cheaper??) metric ID. 17mm x40mm 6203RS

 

Measure your shaft it maybe 17mm

If he has a 68 deck it's Double D  and there is a difference between the 36:" deck and the 42" , 48" decks,in Double D Decks.

We don't know his deck size or if it's Double D, 3/4 keyed or Metric.

@68 raider 12 Lots of knowledgeable help here, but need a little more information about your deck and spindle so we can help you better

Post the deck model number tag if it is still there.

If the tag is missing what is the width of cut

post a picture of the spindle shaft and the spindle housing and the mower deck shell

If you have a micrometer or caliper what is the diameter of the spindle shaft in the bearing area, and the spindle housing  inside diameter.

[68 raider 12 3]

I do know that the spindle shaft is a double d, I'm not sure the deck size, I'd have to say it's at least a 48" deck. they guy I purchased it from restored it and the only numbers I have are on the tractor itself and I can't get much information from the numbers I can read. The measurements I got was OD 40mm ID 19mm and the height is around 19mm I'm not sure if I'm measuring wrong or what.

19mm would be about 3/4"  What are the bearing numbers of the ones you got that do not fit???

[gwest_ca-(File Mod) 11,033]

Will guess the hard to read tractor model number is 1-6931

Your tractor is not limited to these decks

1968 42" deck

1968 48" deck

Great, thank you

I went through a similar issue last month with my C175's deck.  I thought I had the correct bearing, but no.  I originally ordered the 17mm bore as indicated by the manual when I needed the 19.  https://www.amazon.com/dp/B0759V3QK8?psc=1&ref=ppx_yo2_dt_b_product_details is what fit.  I didn't know there were two different shaft diameters so now I am set for bearings for both for a long time.

Looks like you bought them ALL!

6203-2rs/c3

[Jeff-C175 7,199]

Just to clear this up a bit:

 

The 6203 style of bearing is widely available with the 17mm center bore.  This is the so-called 'standard' bearing.

 

It is much less available as a  6203 - 12  style.  The number 12 is indicating that the center bore is  12/16 ths, or 3/4"

 

For example, this one is the 3/4" center bore:

 

 

If there are no other 'modifiers' in the part number, the center bore should be assumed to be 17mm.

 

The other numbers and letters indicate the number and type of seals on the bearing.  For example,  2RS indicates two rubber seals (both sides) of which we would typically remove the 'inside' one when installed in deck spindles to allow them to be greased through the zerk fitting. 

 

I believe that the " ZZ " in the part number indicates that it has two METAL seals: [note: technically 'dust' seals, but if they keep out dust, wouldn't they keep IN grease?]

The Z or ZZ describes the one or two dust shields. They are not a grease seal.

Thanks Garry,  is it possible to have BOTH a grease AND a dust shield?  for example,  6203ZZ-2RS  ?   Or, would that even be necessary?  If it has a grease seal, one would think that would keep out dust.

My bearings measure: 3/4"  19mm ID   x 1.59"  40mm OD  X  .46" 11.9mm Thickness.6203-12-2rsC3. Measured with a cheapie Harbor Fright plastic caliper.  These are also used in the flat pulley of the mule drive.
