Hi Dav,
Welcome to the forum please post some photos as everyone likes them, also give the serial number too.
I have included some photos from the parts book as the numbers you gave are not quit right.
Keep up the good work as it is good to see the old machine's still going.
Regards
Daryl

If they are your rollers they are easy to refurb, much easier than trying to find replacements for the RD4, just machine those worn running faces flat and weld a suitable size piece of thick wall pipe to bring them back to original height, if needed, split the pipe in half and weld, once they are machined clean no one will know you have even repaired them.
Make new oversize shafts and machine the old bearings to suit, or make sleeves out of pipe to weld onto the shafts once the worn sections have been machined clean, I did a thread on here a year or 2 ago on this repair job, but I just discovered this new forum doesn't allow me to search for my old threads........
Decent top carrier rollers for RD4 are very difficult to find here in Oz, all those old girls have done a million hours in the hands of some very rough operators.....
