I'm in the process of getting parts for the engine of my 70D and need some help. Can anyone give me any direction on where to look for these parts for the crankshaft.

Part# F3313R Bushing Center Main F1919R R.H main bearing housing w/ bushing & seal F1920R L.H main bearing housing w/bushing & seal.

Any help is appreciated.

KHE 70,I think the only after market supplier of bearings that is still listing is Clevite (Dana Corp.)Go to a heavy duty automotive machine shop that does crankshaft grinding.They are more familiar with hard to find engine bearings.The set number in Clevite is MS 609AL the 2 outside bearings are semi finish(.060)under on the inside to fit any undersize. The center was available in std ,010,020. Rod brg is CB 644 available in std,010,020.Caution on machining of the outside brgs.There is a dowel pin that keeps the brg from moving. Make sure the dowel pin is tight in the castings. I have seen some fall out.We all know that if everthing is perfect.We shouldn't need them ,but I have seen them fall out ,brg turn and shut off oil supply to main and rod.In machining the bearings, I like to see them cut in a good big lathe where you can indicate the housing both verticality and the face of the housing where it bolts to tractor.Don't drive dowel in too far to where they interfere with the boring of the brg.I don't know where you live, but if you can't find brgs email me I might have some sources for you. Earl In Illinois brgs.

KHE 70, those F3313R center bearings are (were) part of the center main package AF3292R..

The L & R main bearing housings aren't (weren�t anyhow) carried from Deere as a service assembly anymore so you will need to buy & press an undersized main bushing in the housing then bore to crankshaft size..

Now to find them.. I don�t know on that center main kit or even the end bearings as Deere didn�t have them for a long time (check again as there are some aftermarket being made & Deere might be selling those now)..

I can�t even say on the L & R bushings as Deere was out there also last time I checked (the number has also been subbed)..

Give �Renaissance Tractor� a call (1-800-784-0026),,, they have or can get most to all the parts you need for that 70D & they carry good parts (better than Deere in a lot of cases),, be prepped to pay though as those diesel parts are getting quite high (I guess just be glad you can still get them)..

Are you actually needing the housings or just new bearings ? If just new bearings the parts book should have a number listed for an undersized bushing that will need to be sized after being pressed into the housings. These should be available through JD,or your local Federal Mogul dist. or even this site check over on the left side under Marketplace - tractor parts.
