I'm putting a one wire alternator on my 4100. I've ordered a pulley for it (it came with one for a 3/8" belt), and while I'm waiting would like to get a jump on getting a belt. The pulley is a smaller diameter than stock. I'm assuming I'll need a smaller belt. For those who have done it, how much smaller of a belt will I need?
Thanks.

I put the alternator on today, it took a little modifying but nothing major. I ended up with a 54" belt, the original is 55" plus.

With a one wire I don't have to figure out where all of the wires go or if the rectifier works, lol. But also I'm planning to ditch the instrument panel and go with a 3 gauge replacement that will include an ammeter.

If you have generator that drives the tach I like the unit sold on this site with tach drive.

Why go with a one wire? It is sooo easy to go with a three wire on a 3 cyl tractor and then the original warning light still works.

OK, thanks, if it's that close I'll just wait and see if the old belt will work.

I took the pulley off the generator and had it bored to fit the Delco but most time there's enough adjustment to use the standard belt with a smaller pulley.
I prefer using the 3 wire Delco setup, simple install and retains the charge light on the dash.

Restoration Story: 1964 JD 2010 Dsl - Part 2 - by Jim Nielsen. Despite having to disassemble the majority of my John Deere 2010's diesel engine, I was still hopeful I could leave the engine-complete with crankshaft and camshaft-in the tractor. This would make the whole engine rebuild job much easier-and much less expensive! I soon found however, that the #4 conrod bearing had disintegrated, taking with it chunks of the crankshaft journal.
