Drive Belt Replacement

[PlainEdCB]

I have 2 Super Zs and a Raptor SDX. Replacing drive belts (especially when the drive belt breaks or comes off while mowing) is a pain. Does anyone have any tips, tools, etc. to help?

Keep a piece of wire or starter rope to help with tension springs. It beats wrangling the springs with a large screwdriver.

Good thought. I usually use vice grips but Hustler makes it next to impossible to get any leverage. I saw a post using trampoline spring puller. Similar to the starter rope approach.

Thanks

When the spring tension is so great that you cannot pull back by hand, take a ratchet strap tie down, hook good mechanics wire to end that is hooked to spring, and slowly tension spring until close to bolt that you hook spring to, and push into place. Caution: use safety glasses and watch spring. If the spring let’s go and pops you in the face it will be very bad.

Need a lot heavier and longer version. I make my spring pullers. You want the hook part nearly as large as the spring wire diameter so don't give during the pull but tapered so you get it under the spring hook.

All depends on how the spring is attached. Most I use my spring hook tool to remove the spring but are one of some OEMs that the spring is not to be removed. Those usually have a square hole in the idler arm for a pull bar. And had one that I had to ratchet strap to remove the spring tension there was no other way.

And you sooner or later run those that uses compression springs instead of the tension springs most of us commonly see. Currently working on a JD 652R that uses compression springs.

On top of that on some OEM the drive belt replacement require dropping the hydros as there is no clearance to get the belt on their pulleys; unless, you do. Bad Boy I had in earlier was that way.

Here is the set I have made. The shortest of these is 16". Now of course I got smaller ones for the governor and carburetor springs and those have a pusher end too.

The one that has backbone razor under it actually has a bent end for the Cub Cadets RTZs I replace drive belts on. Some of you may have seen these where mounting point is offset from the hole that you pull the spring through.

And the skinny one was for some springs that it is nearly impossible get to the spring mounts. Haven't used it in a few years. The bottom one is the one I use the most.

Great ideas from everyone, thanks. I just popped a deck belt on my SDX. It only has 10 hours on it. And in the interest of safety it looks like I have to damn near dissable everything to get to the belt. Love my Super Z.s. SDX, not so much.

I have a problem with the drive belt which came off when it was struck by a branch. I can't seem to move the idler pulley over to the right enough to get the belt back on. Is there a way to loosen the idler pulley arm so I can move it over to get the belt on?

I found out how to change the deck belt with no tools. Pretty simple once you understand where to work on it. I have a Raptor SD 54" Mower.
Belt Change with no Tools

I can install or remove the belt in under a minute.

One other thing I did to make service easier it to replace the bolts holding the plastic covers with removable knobs. Cheap at less than $5 each. Real fast and easy to get the covers off to clean out the grass as well as to change the belt.

I have 350+ hours on my factory belt? If you going thru them at 10 hours something is VERY wrong.

Thanks for posting and sharing both the video on replacing the belt as well as for the quick release knobs for removing the plastic covers on the deck!

I just ordered some for mine!

I have a 2014 Raptor SD and have wrestled with that drive belt a few times. A couple of years ago I added the frame reinforcing kit from Hustler that minimizes frame flex and that has helped a great deal with my rough 3 acres of yard. I also added a brace or two that wasn't on my mower, one in the back between the two hydros.

Last week my drive belt popped off again and I saw the idler pulley spring was off. There is an adjustment where the idler pulley bracket mounts to the frame. Over time it will loosen and allow the pulley assembly to drop a bit. It's a fairly easy adjustment, just tighten the nut until the bracket is stiff and then back off a hair so it moves freely. I couldn't find the hook I used to use to pull that idler spring so I bought a "Performance Tool Brake Spring Hook Tool Ampere" at Advance Auto Parts and it worked just fine.

By-the-way, that bracket I added between the hydros had to be removed to give me enough room to get my hands up there. I sure hope the newer Hustler mowers don't have that drive belt problem!

Since the idler pulley spring had come off I noticed it didn't seem go into the hole as fully as I remembered it so I bought a new spring at my Hustler dealership. It's a lot easier to put the spring on in your garage or driveway when the belt is still on the mower than in the grass at the bottom of a hill (been there, done that).
