Uni-joint replace number

[Steptoe]

OK, went to my bearing shop today [allied bearings]and asked for the number.

what you need is a TOYOTA TCM [forklift]

part number 901004

20 mm caps,, 40mm to external edge of clips

he seems to think this is an international number, that is stocked or can be cross referenced,,, hope this helps some-one.


this is the result of " weird vibration" thread

I have called several places. That number isn't a Toyota part number, so I called our Allied Bearing here in Oklahoma and that part number doesn't work for them either, so apparently it isn't an international number.

At Toyota, they have no way to get a part by the dimensions, they have to know the year, make, model, and type (Gas, Diesel, Propane, Electric) of forklift before they can help me.

Try here for a supplier in Australia.

Old story revisited.

From years ago:

I recently spoke with Koyo USA [the u-joint mfg.]. They have 805 u-joints [in Japan] part # UJN-2057 for the XS1100. The problem is that the part is a proprietary item-no one can order them except Yamaha. I spoke with Yamaha USA today and told them they have a replacement u-joint available for the XS/XJ 1100--just got the old line the part has been discontinued. The story is replaceable, available, and most definitely unobtainable.

I talked with my local bike shop today. He did some checking and apparently can still get that u-joint from Yamaha.. for a mere $168!!!

My other source's 42.50 is looking better. I wonder how much to ship one across the big pond from Aussie?

I just checked my local bearing supplier to find that he has 10 of them under the number 901004 on the shelf. The computor lists it as 20 x 40 as stated, with internal clips. I held it my hand and confirmed personally with a vernier. It has an optional grease nipple (zert) in one cap but can be removed once the joint is packed. The brand is Turret, which I havent heard of before and it had another number on the box as well. UI 2809A. They're not cheap though. $73.00 NZD plus 12.5% tax. Probably not bad for 30 years of use but it's a lot to part with for such a small part. His computor also lists it as a replacement for Suzuki ATV's but it didnt sat what model. Maybe another search avenue.

Starting to loose the plot....

Just checked another supplier for the Koyo number and it cross references to the Turret 901004. But.... It turns out that different manufacturers measure their joints different ways. The 40mm can be measured from the outer edge of the clip groove to outer edge, innner edge to inner or, wait for it, One even does outer edge to inner edge (really centre to centre of the groove). All are listed as 40mm UJ's but they are all different. I looked at one for 30 bucks that was 35mm inner to inner and a neat 40mm outer to outer edge (of the groove), and the clips were 2 1/2 mil thick. So what are we looking for. What is the measurement inside the yoke and to what edge, inner or outer?

[b.walker5]

And this is what I'm talking about.

The Koyo number, N2057 crosses to Matsuba UJ 112 in this list. Note the 35mm measurement, and the application. I can get these locally for about $35 NZD but are they the right one. Steptoes first post has the 40mm to the external edge of the clips, so if these are measured to the internal edge then they should be fine.

[b.walker5]

Okay, Time to give this up, I dont need one.

The Matsuba number that crossed from the Koyo number crosses to a Neapco number. 1-0028. Measured in imperial, internal clips, and widely available across the US. Slightly shorter at 38mm, and I think Tod has already seen this, but personally I dont think this would make a blind bit of difference, as the joint would tend to self centre at speed anyway. Anyway thats where the trail leads for those who cant get the 901004 that Steptoe has identified.

One that's too short wouldn't self center. Cintrifigul force would pull it to one side and it would stay OFF center and vibrate. BUT... As was mentioned before, I wonder if you could get a 1mm shim for each side that would be tough enough to withstand the forces placed on it?

Given some time, I could machine some 1mm spacers on the lathe. 20mm ID, what would the OD need to be?

Tod

Sorry Tod, I dont agree. If the cross is evenly balanced on all 4 legs it shouldnt pull to one side, and centrifugal force is exactly what would hold it centred. Simple physics really. The only "fly in the ointment" so to speak would be the grease nipple which could create a rotational imbalance, but I would remove it after greasing anyway, after all the first grease fill lasted 30 years, and it's unlikely to need another shot 30 years from now. The "forces" placed on the joint are lateral, with the legs of the joint being pushed against the side of the caps, not radial, even though it's a rotational device, so any spacer fitted shouldnt need to be anything special.

Napa

I went down to the local Napa today and they have that u-joint in stock. Here in Canadian Napa's the number is listed as part#1-0028. It apparently is a common u-joint for PTO's. It is also found on 71-73 Dastuns and 81-84 Toyota trucks. The supplier for Napa here is Neapco. If you go to Neapco.com you can find it in their stock and read the measurements to be sure yourself. They sell for 38 bucks (canuk). The numbers on neapco's site are the same as the Napa numbers I have here. Hope this helps.

[trbig]

I checked around at my NAPA and that u-joint is common, but it's the 20mm x38mm that everyone has. Wondering if I should take my caliper and measure one of them to see exactly where they are measuring it at.

By the way, the NAPA # for that u-joint here in the U.S. is a #392. $27.99 U.S.
