Frequently asked questions Straight answers, from people who run equipment too.

Parts that look the same can differ between serial ranges. The serial is how we confirm fit before anything ships, so send make, model and serial every time.

Send your make, model and serial number, the hours, and a few photos if you can. We'll sort out what needs replacing now and what can wait.

Rubber tracks are sized by width, pitch and number of links, and these can change within one model. Send the serial number and a photo of the track's inside or sidewall markings and we'll match it.

ACE Track groups come preassembled and ready to bolt on; ACE chains are available as bare rails if you're reusing your shoes. R-Brand comes as preassembled track groups.

Single bar grips best on steep ground. Double and triple bar turn more easily and are gentler on the machine on firmer ground. Tell us where it works and we'll suggest one.

New chains on worn sprockets wear out faster, and new rollers on a stretched chain do the same. Order the longest-lead parts first and have rollers, idlers and sprockets arrive with them, so the machine is only apart once.

The make, model and serial number, and what the machine works in. Tell us which parts you need, or send photos of the worn parts and we'll help you sort it out. We cover CAT D3 to D11, John Deere 450G and up, and most newer Komatsu dozers, typically from the late 90s to current.

We can typically get parts for dozers from the late 90s to current. Parts are hard to find for dozers built in 1995 or earlier, like the CAT D6D and John Deere 350B, 350C and 350D, and for discontinued brands like Terex, International and Dresser, so we usually can't help with those.

Order by noon PT and we can usually get small orders on a truck the same day, and full undercarriage packages the next day. Some tracks are built to order, which can take a week or two before they ship. See the shipping policy.

Custom factory orders, such as a special shoe width or style, take 3 to 4 months, so plan them ahead of the season.

Delivery times depend on the trucking company. We'll tell you when it ships.

Undercarriage parts carry a 1-year full replacement warranty, with no pro-rating. Final drives carry up to 3 years. Shipping and labour aren't covered. See the claim steps.

No. FEMAC, Baltrotors, Wreko and xCrane equipment is not covered by our undercarriage warranty, and our undercarriage ship times don't apply to it. Ask us about warranty and lead time for the model.

Yes, on orders over $500, attachments included. Ask when you request your quote; terms are set by our financing partner.

A roller that's leaking oil or has a flat spot is done, whatever its hours.

It depends on the ground, the work, track tension and how the machine is run. We won't quote a number we can't back up; tell us the machine and the ground and we'll give you an honest idea.

FEMAC notes that return-line pressure above 15 bar can make the motor seal leak, and that running a mulcher off a breaker circuit can lower its performance. Send your auxiliary hydraulics and we'll check the fit.

It depends on the chain. ACE PPR chains are our premium line, built to get wear life close to factory heavy-duty chains. Tell us what your dozer works in and we'll give you a straight answer on whether ACE suits that ground.

It's what you pay for the undercarriage divided by the hours it lasts. A cheaper chain that wears out early can cost more per hour. A chain that lasts close to factory heavy-duty life, for a fraction of the price, costs less per hour.

Test it before you replace it. A case drain test checks the travel motor for internal leakage and shows whether it's worn out. Always follow your owner's manual when testing. Watch how the case drain test is done.

On top of the machine, the pin boss and the lip of each shoe should lead toward the front, the idler or blade end. If the trailing edges lead like scoops, the track is on backwards. Watch the track direction video.

Look for wear on the rail, the pin boss and the link face. Tape over four pitches to check for stretch, measure link height, and check the pins and bushings. Compare what you find to your machine's wear chart. Watch the track wear video.
