The Kubota SVL90-2 is listed with one track size, 450 x 86 x 58B (450 mm / 17.7 in wide, 86 mm pitch, 58 links), in a C-lug, D-lug or Z-lug tread. This guide covers how to confirm the fit, the signs of wear and the SVL90-2 sprockets, idlers and bottom rollers to check.
Searching for Kubota SVL90 tracks? The tracks in our catalog are listed for the Kubota SVL90-2, in one size and three tread patterns. This guide gives the Kubota SVL90-2 track size, how to check the fit before you order, the signs that tracks are worn and the SVL90-2 sprockets, idlers and bottom rollers to inspect while the tracks are off.
The short answer
Our catalog lists one track size for the Kubota SVL90-2. Width, pitch and link count are the same on every listing, so the only decision is the tread pattern.
| Track size | Width | Pitch | Links | Tread |
|---|---|---|---|---|
| 450 x 86 x 58B | 450 mm (17.7 in) | 86 mm | 58 | C-lug |
| 450 x 86 x 58B | 450 mm (17.7 in) | 86 mm | 58 | D-lug |
| 450 x 86 x 58B | 450 mm (17.7 in) | 86 mm | 58 | Z-lug |
Source: Excavator Parts Direct catalog, November 2026. Sold as a single track (price is per track). The catalog lists 2 tracks per machine.
Read the size as width x pitch x links. A 450 x 86 x 58B track is 450 mm wide, has 86 mm between link centers and has 58 links. The three treads share these dimensions, so each one matches the size on the machine. If your old track carries a different size, check with us before you order.
If the size is still readable on your old track, use it. If it has worn away, take three measurements:
Width
Measure across the track from one edge to the other. An SVL90-2 track should measure 450 mm (17.7 in).
Pitch
Measure from the center of one link to the center of the next. The SVL90-2 track has an 86 mm pitch.
Links
Count the drive lugs around the inside of the track. The SVL90-2 track has 58. Mark your starting lug with chalk and count twice.
If your figures read 450, 86 and 58, you have the right size. Our guide to measuring rubber tracks walks through each step with diagrams.
Confirm the model
Read the model plate on the machine. These sizes are for the machine listed in our catalog as the Kubota SVL90-2. If the plate reads SVL90 without the -2, or shows another model, contact us with the serial number and we will confirm the right parts.
Match the size
Compare the size on the old track, or your measurements, with the table above. If the pitch is not 86 mm or the link count is not 58, stop and check before you order.
Choose the tread
The SVL90-2 track is listed in C-lug, D-lug and Z-lug treads. The right one depends on the ground the machine works on most and the jobs it does. Tell us about the work and we will help you choose.
Look underneath first
Before the new tracks go on, inspect the sprockets, idlers and bottom rollers. New tracks on a worn undercarriage wear out sooner.
Our advice
A size that is checked, not guessed, is the fastest way back to work. If anything does not match, talk to the team before you order, so you maximize machine uptime and avoid a return.
These are the checks we recommend on any compact track loader, and they apply to the SVL90-2.
Walk around the machine and look at the outside of each track. Deep cuts, lugs that are worn flat or missing, and steel cords showing through the rubber all mean the track is near the end of its life. Check the inside face too, where the drive lugs meet the sprocket.
If a track keeps going slack after you adjust it, the track may not be the cause. A track adjuster with failed piston seals cannot hold tension, and worn sprockets add to the problem. Here is how to check rubber track tension. The correct tension figure for the SVL90-2 is in your machine’s operator’s manual.
When sprocket teeth wear sharp, they stop holding the track cleanly. The track can slip or jump through the sprocket, and the shock load travels into the final drive. If you see or hear this, stop and inspect the sprockets before you carry on.
If a set of tracks wears out well before the last set did, look at the parts underneath before you fit new ones. Material packed between the sprocket teeth, rollers and track also speeds up wear, so keep the undercarriage clean. Our guide to spotting a worn sprocket shows what to look for, and these five tips to extend rubber track life cover other common causes.
Spinning the tracks, unnecessary reversing, high travel speed when it is not needed and always turning in the same direction all add wear, to the tracks and to the sprockets that drive them.
With the tracks off, the whole undercarriage is in plain view, which makes a track change the best time to inspect it. Here is what our catalog lists for the SVL90-2:
| Part | Per machine | Weight each |
|---|---|---|
| Drive sprocket | 2 | 25.0 kg (55.1 lb) |
| Front idler | 2 | Not listed |
| Rear idler | 2 | Not listed |
| Bottom roller | 10 | 26.0 kg (57.3 lb) |

The sprocket bolts to the final drive, and its teeth engage the track to drive the machine. Our catalog lists 2 per SVL90-2, one on each side. Sprocket wear is hard to judge by eye, so compare yours with an unused sprocket of the same type. Wear builds faster in reverse and at higher travel speeds.
Idlers guide the track around each end of the track frame and work with the track adjuster to hold tension. Our catalog lists the SVL90-2 idler in a front and a rear position, with 2 of each per machine, so choose the position you need when you order. With an idler off, it is also the easiest time to check or replace the track adjuster.
Bottom rollers run along the underside of the track frame and carry the machine’s weight on the track. Our catalog lists 10 per SVL90-2. Look for flat spots, worn flanges, oil leaks and rollers that no longer turn. We advise changing bottom rollers as a set, because a single new roller sits proud of the worn ones and wears faster. Our guide to bottom and carrier rollers explains what each roller does.
Our advice
If the sprockets, idlers or rollers show wear, replace them with the tracks. It is one job and one round of downtime, and the new tracks start on a sound undercarriage.
These are the SVL90-2 parts in our catalog. All four are on the Kubota SVL90-2 parts page.

The correct tension figure is in your machine’s operator’s manual. A track that is too loose can come off, and a track that is too tight wears the undercarriage faster. If tension will not hold, check the track adjuster.
Common signs are deep cuts, worn or missing lugs, exposed steel cords, a track that will not hold tension, a track that slips or jumps on the sprocket, and tracks that wear out much faster than the last set. Check the sprockets, idlers, bottom rollers and track adjuster at the same time.
