New Holland 57 3PL ROLABAR parts

Hi, first post.

I have a pair of old NH57 mounted ROLABAR rakes, and I live in Australia.

NH had a manufacturing operation here for around 3-4 decades that is now closed. They made these 2 rakes, which I bought years ago from 2 different owners quite a distance apart from each other. The plan being to restore one to as new, using the other as a parts donor. I'm at the painting stage now. I thought they were identical to the rest of the world's NH57 rakes but there is a difference. The Tine bar bearings...

When I look at the NH parts manuals and every webstore where I can find a listing for this part (481387) shows a tine bar bearing that has an OD on 47mm or 1.85". Searching AG parts stores shows that this is a common tine bar bearing size used by a bunch of side delivery rakes / windrowers.

However both my rakes use a bearing with a bigger OD (52mm), not 2" (50.8mm) but 52mm. Same 3/4"bore etc and looks similar, but has that bigger OD. I have read somewhere that the old CASE 281 side rakes had the same bearing, but can't confirm. I have a bunch of bearing PN's (NT 900537, IHC ST505, etc) none of which score a hit when I search for them.

The nearest available bearing I can find is a fairly common AG bearing called a 205KRP2. Its inner race is only 21mm wide vs. the 26.75 mm of mine, and the outer race is 15mm vs. the 17mm of mine. It would probably work, if I put a 5mm spacer over the stud, but that is as good as I can do right now.

So my questions are: Does anybody have a source of these bearings? Perhaps a CASE 281 (vintage rake) parts stockist?
If not does anyone here (OZ based I assume) have some knowledge of these locally made NH rakes and who might carry parts for them? The closest NH dealers couldn't care less, all they want to is to sell and service new 4WD cab tractors...

Thanks in advance... :)
 
HI Mungus

I am here in Oz as well and have two ground drive NH rakes a 56 and super 56 I think. I have done tine bar bearings on these. I went to a former New Holland dealer in Central Western NSW and got what I needed. My neighbour has a PTO drive 57 just spoke to him and the bearings are the same
as a ground drive machine. His and my suggestion go genuine they should be off the shelf. It might be time to find a new New Holland dealer. You can also make a crude puller to remove the bearings with a short length of correct diameter pipe and flat welded on one side with a suitable sized
hole drilled to allow the stub through on with the nut tighten and out it comes. Where are you? I might be able to help.

Thanks Matt, quick reply.

I already have all the bearings out of both 57 rakes (20 bearings for 10 tine bars). Most came out OK using the tube puller shown in the owners manual, but some were a real pain, being too tight for the puller, OR the bearing being too worn, in which case it just pulled the inner race and bolt out of the bearing. So in those cases (3) I had to MIG the centre to the outer and re-pull. One was so tight that not even swinging on a 1.5m extension bar would budge it. So I had to use the plasma cutter and carefully remove the inner race / balls, and then slice the outer race, that worked! In all 9 out of 20 tine bearings were re-useable, albeit 3 have flat blade screwdriver tops on the studs, which you probably know, are not a great idea. One set of tine bars had them, the other the later and much better allen key heads. So I likely replace 4 of them.


Yes I may try to find another NH dealer. My old one closed down and so I've been trying to find another one who's half decent.
Using the 205KRP2 bearings will work, the ID and OD are the same, and the inner race is raised to 21mm, its just that you need a 5mm long 3/4" ID spacer on top to get it just right. They aren't expensive and are always available, but yes I would prefer an OEM correct bearing. Thanks for that.

Weird that NH OZ did that, perhaps they got a big pile of them cheaply back in the day?
 
Hi Mungus

Sounds like you are winning and have all the good gear to get the job done. The allen key studs are so much better than the screw driver slots. The spacer may be the way to go. There are good New Holland dealers out there I am fortunate here have the current one and former one both with
helpful knowledgeable staff.

Good luck with it!

Thanks Matt, can you post the name / location of your NH dealer? I don't mind getting stuff posted to me as theres no one close by anyway.
 
Hi Mungus
I found a possible Massey Ferguson equivalent for the number st505 and 900537 numbers you gave.....831858m1. This part is also no longer available, but some guys at B&B
Equipment in Toowoomba Queensland seem to have 5 of them. I have dealt with them a couple of times. Maybe get in touch with them and ask the measurements of this
bearing....maybe it will be a match? There phone number is....07 4630 2000. They have a website too.
Hope this helps, Wayne
 

Thanks yes I have that MF number too. Nothing available when I search for it. I’ve web searched every cross reference number I can find, nothing! But that’s a good lead, thanks.
 

For the benefit of anyone else reading this I have got some on the way now and the CNH PN is 86523991.
 

As a clue the Australian 57 rakes use the 55 tune bar and associated parts. That’s why the later rake parts or the non Australian rakes don’t list the correct part numbers....
