Manufactured to OEM specifications, this seal ensures optimal compatibility and longevity under extreme load conditions and harsh environmental factors. Its robust elastomeric compound and precision metallurgy provide superior resistance to wear, heat, and hydraulic fluid degradation, making it indispensable for maintaining drivetrain integrity and preventing contamination ingress.<\/p>\n<p>Technically, the 077-2989 Seal features a high-performance lip design that maintains consistent contact pressure within critical hydraulic and mechanical assemblies, ensuring leak-free operation and enhanced machine uptime. The seal\u2019s dimensions and material composition are optimized for dynamic applications, providing excellent resilience against pressure fluctuations and mechanical vibrations typical in articulated dump trucks and compactors. By minimizing friction and wear, this seal contributes to improved fuel efficiency and reduced maintenance intervals, ultimately lowering total cost of ownership. Its proven reliability in heavy-duty Caterpillar equipment underscores its role in sustaining peak operational performance in demanding construction and mining environments.<\/p>\n<p>\ud83d\udd17 For detailed specifications and purchasing options, visit the official Caterpillar 077-2989 Seal product page at <a href=\"https:\/\/allparts.expert\/es\/parts\/mining\/caterpillar-077-2989-seal-0772989\/\">AllParts Expert<\/a>.<\/p>","protected":false},"excerpt":{"rendered":"<p>8TF-D400D Articulated Dump Truck<br \/>\n2JJ-D40D Articulated Dump Truck<br \/>\n9LR-D350E Articulated Dump Truck<br \/>\n2YR-D400E Articulated Dump Truck<br \/>\n1MD-D400 Articulated Dump Truck<br \/>\n7CD-CB-614 Paving Compactor<br \/>\n7BD-CP-553 Paving Compactor<br \/>\n6ZD-CS-551 Paving Compactor<br \/>\n7AD-CS-553 Paving Compactor<br \/>\n6NL-561H Pipelayer<br \/>\n1KW-561M Pipelayer<br \/>\nCPH-561N Pipelayer<br \/>\nTAD-561N Pipelayer<\/p>","protected":false},"featured_media":16893,"comment_status":"open","ping_status":"closed","template":"","meta":{"_acf_changed":false,"_joinchat":[]},"product_brand":[36],"machine-type":[21022],"model_no":[42308,27615,27616,36605,79040,79041,79042,7163,7169,21042,7164,21043],"product_cat":[144],"product_tag":[96645,96226,96255,96252,46706,79479,96647,96220,96646,96189,52569,64098,96644,96643,96649,96227,96648],"class_list":{"0":"post-17057","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_brand-caterpillar","7":"machine-type-articulated-dump-truck","8":"model_no-561h","9":"model_no-561m","10":"model_no-561n","11":"model_no-cb-614","12":"model_no-cp-553","13":"model_no-cs-551","14":"model_no-cs-553","15":"model_no-d350e","16":"model_no-d400","17":"model_no-d400d","18":"model_no-d400e","19":"model_no-d40d","20":"product_cat-mining","21":"product_tag-077-2989-hydraulic-seal","22":"product_tag-1kw-561m-cat-pipelayer-seal","23":"product_tag-1md-d400-articulated-dump-truck-gasket","24":"product_tag-2jj-d40d-articulated-dump-truck-seal","25":"product_tag-2yr-d400e-dump-truck-spare-parts","26":"product_tag-6nl-561h-pipelayer-parts","27":"product_tag-6zd-cs-551-paving-compactor-gasket","28":"product_tag-7ad-cs-553-compactor-seal","29":"product_tag-7bd-cp-553-cat-compactor-parts","30":"product_tag-7cd-cb-614-paving-compactor-seal","31":"product_tag-8tf-d400d-dump-truck-parts","32":"product_tag-9lr-d350e-cat-seal","33":"product_tag-cat-0772989-gasket","34":"product_tag-caterpillar-077-2989-seal","35":"product_tag-caterpillar-seal-0772989","36":"product_tag-cph-561n-pipelayer-gasket","37":"product_tag-tad-561n-pipelayer-spare-parts","39":"first","40":"instock","41":"shipping-taxable","42":"product-type-simple"},"acf":[],"_links":{"self":[{"href":"https:\/\/allparts.expert\/es\/wp-json\/wp\/v2\/product\/17057","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/allparts.expert\/es\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/allparts.expert\/es\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/allparts.expert\/es\/wp-json\/wp\/v2\/comments?post=17057"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/allparts.expert\/es\/wp-json\/wp\/v2\/media\/16893"}],"wp:attachment":[{"href":"https:\/\/allparts.expert\/es\/wp-json\/wp\/v2\/media?parent=17057"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/allparts.expert\/es\/wp-json\/wp\/v2\/product_brand?post=17057"},{"taxonomy":"machine-type","embeddable":true,"href":"https:\/\/allparts.expert\/es\/wp-json\/wp\/v2\/machine-type?post=17057"},{"taxonomy":"model_no","embeddable":true,"href":"https:\/\/allparts.expert\/es\/wp-json\/wp\/v2\/model_no?post=17057"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/allparts.expert\/es\/wp-json\/wp\/v2\/product_cat?post=17057"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/allparts.expert\/es\/wp-json\/wp\/v2\/product_tag?post=17057"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
