9153152 Bottom Roller: Replace One Roller or Inspect the Whole Undercarriage?

A single bottom roller is a possible replacement only after the other rollers, track links and mounting position have been checked. A visibly damaged roller does not establish that the rest of the undercarriage is serviceable. For an enquiry referencing 9153152, separate the fitment check from the decision about how many components to replace.
Check the position before choosing the replacement scope
Record the machine serial number and the roller position on the left or right track frame. The website lists 9153152 for EX60 / EX60-5; this is a catalogue reference to verify against the machine parts book, not confirmation for every machine carrying that model name. Photograph both mounting ends, the track contact surfaces and adjacent rollers.
A workshop inspection should distinguish oil leakage, a cracked roller body, restricted rotation, uneven tread wear and loose or damaged mountings. Each finding leads to different checks. For example, a loose mounting requires examination of the fasteners and frame attachment as well as the roller. A replacement roller alone will not correct a damaged mounting surface or an unresolved track alignment problem.
| Check | Record for comparison | Why it matters |
|---|---|---|
| Mounting interface | Hole centres, hole diameters, mounting-face spacing and bracket orientation | An exterior resemblance does not establish that the roller seats correctly. |
| Contact geometry | Tread diameter and width, flange arrangement and flange spacing | The roller must match the track system and designated position. |
| Remaining undercarriage | Wear measurements and inspection findings for adjacent rollers, links, idler and sprocket | A local defect and system-wide wear require different purchasing scopes. |
Compare one roller with a wider replacement plan
| Option and condition | Parts cost | Workshop time | Delivery and downtime |
|---|---|---|---|
| One complete roller: a local defect with other components within the applicable service limits | One roller plus specified fasteners or related items | Removal, mounting checks, installation and track adjustment remain necessary | May limit the order scope; verify dispatch and whether other worn parts could cause a second stoppage. |
| Several rollers or an undercarriage package: inspection identifies multiple worn components | More components; obtain itemised quantities by position | More installation work, potentially sharing access and setup | Plan delivery of the complete required set before disassembly; a missing component can extend the stop. |
| Further inspection before ordering: wear or mounting condition is uncertain | Inspection expense before committing to parts | Measurement or specialist inspection time | Avoids ordering a roller that fits the model description but not the actual worn system. |
Use the machine-specific service limits and track tension procedure. General undercarriage guidance supports checking rollers and associated components together, but it does not supply an EX60 wear limit. No universal replacement interval, cost saving or service-life figure is assumed here.
What to send with your enquiry
Send the serial plate, the parts-book reference, the failed roller position, measured mounting and tread details, and inspection findings for adjacent components. Request the supplied fastener scope separately.
View the 9153152 product listing or contact GUANGZHOU JIAJUE MACHINERY EQUIPMENT CO.,LTD. Ask for a written supply scope, evidence for any claimed specification, and confirmed availability and dispatch terms for your enquiry.
Evidence note: The product reference and Figure 1 come from our 9153152 listing. Caterpillar undercarriage maintenance guidance supports the general inspection approach; its dozer guidance is not an EX60 specification. This is a purchasing guide, not an installation procedure or a report of a completed customer repair.
