645 serial number

If it's a 645(not a645B), 3012 were made, between 1965-1971.  Middle of the run...

According to my serial # book your 645 would be a 1965. Starting # for 1966 was 1318.

1965 was from 101-1317. 101 was the starting serial #.

Never had the differentials apart, rear finals have been broke 4 or 5 times from operator error due to getting front wheels off the ground with full power and blows the cage on the ground. Every 8 to 9 years the engine was majored, the tranny we put two sprague assemblies in it and 2 converters, the high gear drum would break the nose off on the cover 3 or 4 times. Put a new hydrolic pump on it in 1979 just had it apart for a new input seal and the hyd. Shop said it looked better than a new one. The drive shaft splines went out once on the power steering pump, replaced and never put the seal back in so tranny oil would oil it ,still going. She could use a new set of lift barrels and rods as they cracked by the trunnions mounts and have been welded lots. The cylinders have been rebuilt in 1980 and in 1991. Center bearings 2 times, the driveshaft in the middle with the ball drive system has been new 4 times. The bucket has had been rebuilt twice with new sides floor and frog as it would get thin between the teeth. That's where I learned to stick weld ,my dad set it up and put a can of 7018 in the bucket and weld the top two sticks then move down two feet and do it again then go under and get the bottom then let it cool while chipping sl*g then hit the next spot till you burned up 120 pds. Of rod. The last five years it's been a stand by and not doing much light sight work and loading trucks. We used to do road work and her record was 4000 ton in 15 hrs loading out of a stock pile. The state guys could not believe that old loader never missed a load. It was a load ever 3 min. For 15 or 16 hrs. It took 45 gal. Of fuel and the hyd. Valve under your arm was so hot it would sizzle if you spit on it. It ran years longed with less problems than 745 c the 11000 series had head issues and ran hotter with the oil cooler and more engine trying to get rid of the heat. Wish could buy both new again , they would still give the other companies a run for the money. At the time we would put them in pits with cat,Michigans, and the Green noise makers and move more tons. Lots of long days but it was when you and a crew were happy doing a job. Now crews just want 5 hr days and high wages and new equipment or they can't run it. Oh and don't forget about texting and whining. So back to what it owes us, not much for a 18,000$ purchase .

Thanks for taking the time to share the details of service history - very interesting! Thirty-nine years since you bought it!! The 745 loader I had was owned by the city works yard and I don't know the true hours on it but it was 18 years old when I bought it. I had it and used it for 6 years and aside from batteries, filters, oil and grease I don't think I spent as much as $50 on parts, I was very pleased.

It was a very thought out design. 45* bending was huge gain. They still run a 2 speed forward? And also the people you meet over a 50 year old loader commenting from all over. That loader I would take they have about the same sound also.

Youtubes are pretty easy (otherwise I couldn't do it, LOL)  Go to youtube, hit share, and the address pops up highlighted in blue.  Hit copy, and you copy it.  Now to post, hit reply, lower left of this forum. A black box pops up, with a bunch of symbols, in the top line, and Font, size, bold, italics, etc .  Above the slanted I for italics, is a icon for a film strip, hit that, and another box pops up.  It will have an address line at the top, separate. Click once there, and your cursor will be in the left hand side of the box. Go to the edit button, on your browser, and click, drop down to paste, and click there. the youtube address should be in the box now.  If it has https: www dot whatever, delete the s, before the colon. to see if it works, hit the preview box.  If all is ok, hit submit, at the bottom.  If I can do it on an apple Imac, running chrome, I'm sure you can figger it out, I have faith in you

Hey now that we have the 645 out of the way I'm looking for a td24 if anyone happens to have one
