Belt size

Yea. Years of working in maintenance departments and ya start to remember some things like that. Or at least I do.

Another example of remembering such things is with sealmaster bearings. (I wish all bearing makers used similar numbers). But seal-masters mounted bearings, the # is how many 1/16's of an inch the bearing is. IE: SF-16, the 16 is how many 1/16ths it is. 16/16=1" bearing. A SF-24......24/16 = 1-1/2" bearing.

I like when numbers of things makes sense. I am a math and numbers type of guy. I remember the stuff easily. What I dont like are meaning or seemingly meaningless numbers. Like oil seals:confused2: or some tractor model numbers, or metric roller bearings. What exactally does the numbers in the 6000 series bearings mean????? Who knows? Simple things like this could just make life soooo much easier.

Yes I do understand that with regard to numbers - I have a good recollection for numbers telephone etc from a long time ago..

Also, did you know the Kubota numbering system for their loaders IE 421 (like on my B21) x2.2 (lbs per KG) equals the lift capacity? Check it out your 463 should be 1020Lbs and a 724 is 1592 lbs BUT the caveat is where they measure the lift - at the pins or the bucket.

For the older machines its at the bucket for the newer machines at the pins.

Oh well enough on numbers and measures - the metric system is so much easier if we would have adopted it years ago a MM is a MM and not 1/16" in increments you cant read on a wrench as you get older - can easily see a 11 or 15 mm.

Used to be I could look at a bolt and get the right wrench - today I am lucky to find the wrench in the size I am looking for in 5 minutes. Why is it when you need a 1/2 " wrench all you can find is a 12-13 MM or 7/16 or 9/16 - tools have a way of magically diappearing.

Yep, I knew that about kubota. But actually, it is only the first two of that model followed by a zero. That last number, currently models usually a 3 or a 4, is the number in that series of loader.

Like my 463 for example. It ISNT 463kg, rather it is 460kg and it is the 3rd series of that loader.

The new ones changed to a 524. So 520kg (measured at a different point), but now the 4th series.

I perfer SAE measurments as opposed to meteric, just because that is what I am used to, but there is no doubt that metric is easier. Especially in terms of converting. Since everything is muntiples of 10, 100, 1000 etc. But I cant look at a metric bolt and tell you what size it is, but I can look at a 3/8-16, or 5/8-11, or a 3/4-10 and tell you what it is just by looking. I need the calipers and pitch guage for metric.

I can also look at something and guess relatively accurate in inches or feet what size something is. I cant with metric without some thought. (first guessing in inches/feet, and then doing a quick conversion in my head).

But where I really get lost and need an online calc. for conversion is some of the other types of measurments. Like pressure, and force, etc.

I dont think we will ever see ONE system. And I am fine with the two. But as I said, what I hate is when manufactures make something and the numbering means absolutly nothing.
