Save Time When Replacing Quadtrac Midrollers

A Quadtrac’s midrollers are tasked with keeping the tracks flat to the ground. As with the belts themselves, midrollers eventually wear out. Midrollers typically need replacing when you swap belts—at around 4,000–4,500 hours. And, if you spot a damaged midroller at some point, you’ll need to replace it too, or you’ll risk damaging the belt. 

Swapping the Quadtrac’s original OEM midrollers (pre-2022) is a bit of a chore. You’ll need new bearings, seals, oil—the whole works—every time you need to change out a midroller. When you invest in one of the two midroller conversion kits on the market, future midroller swaps are much easier: You simply bolt the replacement midroller to its center hub component and move along with your day. No need to change oil, bearings, or seals. 

When to Replace Quadtrac Midrollers to Avoid Track Damage

On any track machine, it’s not worth trying to scrape by with damaged or worn midrollers. First, doing so can void your track belt warranty. Second, any time your undercarriage is in less than tip-top shape you’re running the risk of unplanned downtime and an expensive (and emergency) repair. Yes, bad midrollers can damage the underside of the belts, but they can also affect the timing of the track on the drive lugs. Once the timing becomes slightly off, you’ll get extra wear and may even start to see drive lugs popping off. 

Often, belts and midrollers are replaced at the same time, but it’s worth a few minutes of your time to carefully inspect your undercarriage before every season. Did you know that most wear (and damage) to your tracks happens during roading? If you burn up a lot of road miles with your Quadtrac, you’ll need to be extra vigilant to spot damage early. And, you should consider slowing to 18 miles per hour or less on the road to help safeguard the health of your track system. Heat is the top enemy of tracks, and your midrollers take the brunt of the soaring temperatures as you blast down the road.

If you notice a cut or tear starting on a midroller’s edge, you’ll have to keep a close eye on it. If there are flat spots or a significant portion of the coating is missing on your midrollers, you’ll have to replace them immediately or risk damage to the entire track system. If you notice your midrollers beginning to round or dome, with more rubber across the middle of the roller and less at the edges, don’t worry—this is a normal wear progression.

Case IH Quadtrac Midroller Conversion Kits

Option 1: Camso

You have two options if you want to upgrade your Quadtrac with a two-piece midroller conversion kit. Option one comes from Camso. It’s a 12-bolt design, and the kit comes with the conversion hub, hardware, and a 100% polyurethane midroller with a flat face. (The face of an OEM Quadtrac midroller is more rounded.) While this design differs slightly from OEM, there are advantages to running with poly midrollers. Since poly has a lower coefficient of friction than rubber, poly-capped midrollers can run cooler and help extend the life of your midrollers.

Option 2: Soucy

Option number two hails from Soucy. The Soucy version is an 8-bolt design with the same general packing list—a conversion hub, hardware, and a quick-release midroller. The Soucy midroller, however, is a two-ply design. The outer layer is rubber with the OEM convex shape, which the company believes will increase track life. 

The inner layer is UHMW-PE, which sounds like something that should be on a food label, but is a type of polyethylene noted for its solid bonding characteristics. (And it’s slip- and chemical-resistant too.) They’re guaranteed for life against delamination, which is good news if you’re at all concerned about a rubber-plastic sandwich coating your midrollers.

Both the Camso and Soucy kits use the Case IH OEM seals and bearings. Again, once you mount one of these kits, you don’t have to replace the seal and bearings if you have to swap out a midroller due to damage or wear. This cuts the time down to fifteen minutes from roughly two hours of work.  

Fitment for Quadtrac Midroller Conversion Kits

Both the Camso and Soucy kits fit 2008 and later Quadtracs. The original late ’90s models and the 2000–2007 STXs have different shafts/spindles. (You could change the spindles and add the kits to the older tractors, but then the cost of the midroller swap is going to pile up.)

Some time during the 2022 model year, Case IH switched to mounting the two-piece Camso midrollers directly from the factory. And then, beginning with the 2023 Quadtracs, Case IH began using the Soucy rollers as OEM equipment. (They might not say ‘Soucy’ on them, but they are.) So, if you have a 2022 and later Quadtrac, you’ll have to check your midrollers carefully before inquiring about a kit or replacement midrollers. First, your Quadtrac may already be equippped two-piece midrollers. And second, because the Camso is a 12-bolt design and the Soucy is an 8-bolt design, you’ll have to order the appropriate replacement midroller if you need to swap one. 

A Soucy midroller conversion kit is also available for 2018 and older Case RowTracs and SmartTrax systems running with 24- or 30-inch tracks. However, in order to install them, you would first have to switch to wider spindles, so you’d have to foot the bill for 12 (RowTrac) or 6 (SmartTrax) spindles, too. 

Save Valuable Time When Replacing Midrollers

There’s no question that tracks give you unbeatable traction. However, they do come with some drawbacks—high initial cost, high replacement cost, and more maintenance when compared with tires. That’s why you’ll find us promoting tires over tracks most days, especially since modern VF radials and CTIS technology can get you close to the performance of tracks for a lot less money. However,  if you have a Case IH Quadtrac and want to safeguard your investment, consider installing a midroller conversion kit when it’s time to replace your midrollers. Future midroller swaps will only take 15 minutes, versus two hours for an OEM swap. Interested in a kit or need advice on what replacement tracks to buy? Call and talk to one of our track experts.
