ebinmaine 67,259 #1 Posted October 23, 2022 We knew when we got it from @wallfish our 1986 416-8 with the backhoe would need to have transmission seals +/-- whatever... It needs bearings so it'll be split and fixed at some point. What I'd like to do is a transmission SWAP. Rebuild one I have here and toss it in then rebuild the existing one later. I have 2 choices on hand. 1. is an unknown year 8 speed likely from sometime in the 70s because that's the years I tend to aquire. 2. is around a 1980. Both appear to be mechanically solid on exterior inspection. Either way I go, the new one would get 2 new wheel bearings and 4 seals at minimum. Will ~ ANY ~ 1⅛ axle 8 speed replace another? @stevasaurus @pfrederi @953 nut 3 Share this post Link to post Share on other sites
ri702bill 8,283 #2 Posted October 23, 2022 Eric - I'll say yes. You already mentioned the 1-1/8" axle size and you need that for your application. The 1" axle version like the 310-8 is not what you want.... Bill 2 1 Share this post Link to post Share on other sites
953 nut 55,051 #3 Posted October 23, 2022 Based on this repair manual I would say any 8 speed with 1 1/8" axles would all be compatible. 1 1 1 Share this post Link to post Share on other sites
953 nut 55,051 #4 Posted October 23, 2022 One thing to look for on the earlier 8 speeds is the two mounting bolts for the fuel tank/seat support may not be there. 4 Share this post Link to post Share on other sites
Pullstart 62,783 #5 Posted October 23, 2022 (edited) I believe they all had the bolt holes (that are compatible with a seat spring mount as well for round hoods). The “tunnel” sheet metal in early B or C tractors with the gas tank under the hood would have utilized those holes as well. I’m agreeing with the masses, any and all 8 speeds with 1-1/8” axles will work. Edited October 23, 2022 by Pullstart 5 Share this post Link to post Share on other sites

I'd think the spacing would be the same?? 1 1 Share this post Link to post Share on other sites

wallfish 16,982 #8 Posted October 23, 2022 Just swap in another 1 1/8 trans Run that trans that's in there now until you get completely used to operating that hoe. The hoe is BRUTAL on the trans axle bearings when the wheels are on the ground and pulling down digging. Larger base plates for the 2 stabilizers would help with slowing down the digging into the ground as you work. They can work themselves into the ground pretty quickly so always keep an eye on that. 4 1 Share this post Link to post Share on other sites

How big of a platform would you add? I thought about maybe making up a couple that would directly replace the existing seat but maybe two or three times the size? 1 Share this post Link to post Share on other sites

I would bolt something on the plates so they can be removed or size adjusted too. Like 2 pcs of heavy angle each side of each platform. Then it can always be adjusted by length of the angle depending upon the conditions or what you experience. 1 Share this post Link to post Share on other sites
Pullstart 62,783 #11 Posted October 23, 2022 What about an auxiliary landing gear on the front of watch rear tire? You could plumb them in series with the rear landing gear, so both sides get equal pressure whether front or back cylinder. 1 Share this post Link to post Share on other sites

oliver2-44 9,678 #13 Posted October 23, 2022 Verify your brake drum linkage is the same and your good to go. I believe the 6 speed brake drum linkage was slightly different on the 6 speed. 1 1 Share this post Link to post Share on other sites

I'd only use an 8 speed. 4 hours ago, wallfish said: I would bolt something on the plates so they can be removed or size adjusted too. Like 2 pcs of heavy angle each side of each platform.

We use nylon for our crane it work. It's important to remember that a crane outrigger pad is VERY different from a backhoe or excavator foot. A crane pad isn't meant to stop much movement because the crane doesn't pull against the pad. There is NO ground or any other engagement happening. A foot is meant to dig in to the ground to prevent the machine from moving while it it's fighting tooth and nail to do just that. 2 Share this post Link to post Share on other sites
wallfish 16,982 #25 Posted October 25, 2022 Most of the digging in is caused by the tractor being pulled back towards the hole. Too much float by making it too big will probably skid them across the top of the ground more. They need to dig in some to hold. Maybe cut teeth into the angle? see below I was also thinking about adding pins bolted or clipped to the front bucket. Added to the magic drawing LoL Having the front bucket ALL the way down lifting the front puts the entire weight of the tractor on the hoe bucket and and helps to keep it from moving back 1 1 Share this post Link to post Share on other sites
