Need help finding bearing!

[Steve G]

At this point, stuck on one bearing and one seal. Cannot find online or at local houses.

Bearing was completely destroyed, so pulled the other hub to see what was needed. It is a needle bearing with inner and outer sleeves, 40mmID x 58mmOD x 15mm. Only markings are "IKO Japan." No part number. Can't find any bearing those dimensions, other than a thrust bearing which won't work of course.

Closest thing I can find that might work is a sealed bearing (vbx 40BD45DU) which is 40mmID x 57mmOD x 24mm. It's a sealed bearing, so thinking maybe if we can leave off one or both oil seals it will fit.

The oil seal has a part number on it - AQ2671E - which cannot find, but from the few cross reference charts I have found (all in foreign languages) I can deduce it as having dimensions 45mm x 68mm x 11/17. The ID and OD fit with what I can measure on old part. Don't know what the 11/17 means. It is a flanged seal of some sort. Metal with rubber on face of flange and along inner wall. As with the bearing, local supply houses not able to match.

Attaching photos. Any further help much appreciated. If I ever nail this down, I'll post dimensions and part numbers for all bearings and seals needed for the rear hub. Twice now I have had to repair the hub. Only thing that has ever broken on this machine, so figure others will be in the same spot sooner or later.

Did you try Valley Power?

It says IKO and Japan, does it have any numbers?

IKO makes a ton of needle bearings.

Question, do the needles fall out when the inner ring is removed? Cause it is possible you are searching under false measurements. With needle bearings, sometimes there is an inner race, sometimes not. So the bearing you have could have been sold as just the outer race + needles, and the flanged inner race is a separate part. That would change your ID measurement and thus change your search

 

[Steve G]

Yes that occurred to me after I got home and started searching web again. I do know the inner race pulls out. As for needles falling out don't know but will call tomorrow and ask. Unfortunately I don't have the bearing here. No part number at all on the bearing (see photo), and of course they do make tons of bearings. Wonder why no part number.

Also Teachu2, I just emailed Valley Power.

On one of those foreign sites, the AQ2671E seal also appears to be the PTO seal on a JD 3350.

Interesting. A good reference. Can't seem to find a part number for a JD 3350 PTO seal so far from perusing a few sites, but a good lead nonetheless. Looks like the part is an 'oil seal sleeve.' That helps.

Thanks. The very same bearing I had under consideration as my Plan B. In fact, after more extensive searching, I ordered one just like it last night. Not a needle roller. It is however a double-ring bearing and will bear considerable weight. Small tractor of course, so I am reasonably confident it will do the job. Thicker than the 15mm needle roller that's spec'ed, but it's a sealed bearing so I will leave one or both oil seals off and it should fit within a mm.

Oil seal remains an issue, but I have ordered one based on cross ref of the original number, and I think it fits on the flange of the metal part, which is basically a shaft sleeve (separate part). May be wrong, but will know when the seal arrives from Hong Kong. The fact I couldn't get one over here is probably a good sign it's what I need. We'll see.

I will post here along the way, and if the bearing and seal both work, I will list all bearings and seals I used on the hub in a separate post in whatever forum is appropriate, for those who find themselves in a similar situation down the road.

Once again, thanks to all for the help.

D-1600 is fixed and back home. Hub bearings were easy enough to run down with the one exception previously noted. That one required improvisation. About decided Mitsubishi had the D-1600 hub housings cast, and then realized the OD for the shaft bearing into the transmission was an odd size, and had IKO custom make a needle roller bearing to fit. That would explain the absence of a part number on the bearing. At any rate, couldn't find one anywhere for any price. Ended up using a double ball bearing from VXB. Right ID and OD, but thicker. It's a sealed bearing, so left off the oil seal from one side and it fit nicely. Hopefully won't be an issue, as the oil levels in the hub and the transmission are below the level of the bearing. The double roller won't bear the weight of a needle roller, but hopefully that won't be an issue as it is there more to keep shaft centered than bear weight, and the tractor is small of course. Time will tell.

Several gear teeth were chipped. Handled that by building up with a welder and grinding new teeth. Should work fine.

The following is a list of bearings and seals used to rebuild the hub. Hopefully this will save other D-1600 owners some time down the road should they have to rebuild a rear hub. I have owned this machine for over 20 years now, and I have only had to make two repairs, both time rear hubs.

BEARINGS

35MMx72MMx17MM tapered roller
40MMx80MMx19.75MM tapered roller
25x62x17MM roller
40MMx57MMx24MM double row sealed (to replace OEM needle roller)

SEALS

50MMX68MMX7MM
35MMX52MMX12MM
45MMX68MMX8MM TC Metal Spring Double Lip Oil Shaft Seal
40MMX58MMX8MM TC (omit one of two seals NEEDED IF using 40BD45DU sealed bearing to replace OEM needle roller)

Thanks to all who helped with the search.

Nice write up. Thanks.
