71_Bronco 1,072 #1 Posted May 20, 2019 Picked up a couple of used seat springs off Ebay to put on my Commando 8. I have 2 questions though. 1. Does the long part of the "U" go against the seat, or the seat pan? 2. Have any of these springs actually broken from use? Constant flexing over the years? I'm not a big guy (5'7", 150 lbs), but like all things, I cant imagine these have an infinite life expectancy. Or am I over-thinking / worrying for nothing?

I'll have to measure the opening and see how it compares to the 2-1/8" they state in the recall notice. Thanks Share this post Link to post Share on other sites
Racinbob 10,271 #4 Posted May 21, 2019 The 76-77 B-series had a different part # than the C-series but that was due to the B's having a low back seat and different bolt pattern. The bulletin applies the same and the short end bolts to the tractor. 1 Share this post Link to post Share on other sites
71_Bronco 1,072 #5 Posted May 21, 2019 The ones I have are off a '77 C120 according to the ad on eBay. They have a hole pattern of 7" center to center on the springs, both sides of the "U". Share this post Link to post Share on other sites
clueless 2,898 #6 Posted May 21, 2019 Short end tractor, long end seat. My oldest set are 45 years old and I don't thing they've even bent down any and that's with 25 years of my 250+lb butt seating on them. 2 Share this post Link to post Share on other sites

Tried that once ended up having my BIL blow the holes in with his torch, not pretty but it worked. After that anytime I needed to replace a seat on one, finding a seat with the right bolt holes was much easier. 1 Share this post Link to post Share on other sites
71_Bronco 1,072 #9 Posted May 21, 2019 Luckily, the seat I got from TSC has the correct pattern, and the holes all match up with the springs / seat / seat pan. So glad I dont have to try to drill out anything, especially if the springs are really tough steel. Thanks again! Share this post Link to post Share on other sites
