Can anyone tell me the minimum length of these retainers before replacement is needed?  I have to rebuild all six of my rollers and the retainers are all in various stages of wear from thrust forces of the roller shaft.

Hello Will -

Haven't any measurements, but I've used them with the oil channels on the inner ends nearly worn down.

Even though they are shorter, with the snug fit, once they're driven home they're not likely to loosen in service.

If the channels are worn flat you could grind new ones - they provide oil to the axle bushings.

If length means the axis, you wouldn't want the bronze bushing to stick out at one end. The bushings measure 1-5/8th and they fit nicely inside the 1-3/4 steel retainers.
If it's relevant, I sell the bronze bushings for $7.50 each (HG, OC-3, OC-4, OC-6).

I think they'd still be OK down to 1-5/8ths. The shaft would have some back and forth 'slide' in them, but I cannot see that being a great problem, if the oil is kept topped up.

I have the six track rollers installed on the track frames but I can not turn them by hand.  Is this going to be a problem or will they work in?

Have you oiled them up yet? Such that the oil is forced through the roller seals when it's full? It'll often make a gurgling sound as you pump it in. You want those bronze bushings to get lots of oil.

If the seals are installed lip inwards, you might get an air lock, as the oil cannot be forced out, which you don't want. Seal lips should be facing outwards.
Don't use grease! Only exception I've come across is JD Cornhead Grease.

I oiled them with 30w oil as I assembled them.  Once one side had the bushing retainer assembly, seal and clip in I flipped it over, inserted the shaft and prefilled the roller with oil before assembling the other side.  The seals were installed correctly as I was extremely careful on making sure the seals were pointing the correct direction.

I am sure they will be A-OK then. Just friction from the seal surface, I imagine. That'll wane pretty quickly.
I like the ingenious way you filled them as you go  Smiley
