mshowar Posted August 17, 2003 Posted August 17, 2003 Looks like I may have found an engine to go in my 3410S. However I would like to hear what some of you have to say about it. I am looking at getting a new B&S 326431-THD. It is a 16hp which is good I guess if I don't loose any of the low-end torque you all were talking about in one of the other posts. It doesn't have a keyway on the front shaft, needs to use the oil pan from my old engine, and I think it will accept my generator/starter from my old engine too. I don't have any experience with engines or tractors so I am working alone down here in the great southwest. Any words of wisdom will be gratefully accepted.:) - Mark
Kent Posted August 17, 2003 Posted August 17, 2003 Mark, It should bolt right in, once you change the oil pan as you described. Don't worry about losing torque, you'll be gaining quite a bit more. Be aware that the threaded front shaft means you can't run a snowblower as originally done... you'd have to run it from the coneclutch PTO through an interim adapter bracket/pulley setup. The newer engines had built-in 15 amp alternators and used flywheel ring gear starters, instead of starter-generators. You'd have to have the complete engine type code to know for sure, I guess.
Spencyg Posted August 18, 2003 Posted August 18, 2003 I have an older 346431 and it is a great engine...as Kent said, the later ones had the ring gear starter which is about 1000% better than the stupid belt drive starter mine came with... Spence
goatfarmer Posted August 18, 2003 Posted August 18, 2003 I put a 1985 model Briggs in my 3410.It bolted right in.I don't use the front shaft on mine,so that wasn't a problem. I had to buy a regulator for it,but that was the only major expense.
