The guide is supplied in a semifinish bore condition, meaning the bore requires final reaming to size upon installation -- a standard practice for precision valve guide fitment in diesel engine rebuilds. It is installed in the cylinder head and controls exhaust valve stem alignment, heat transfer, and oil consumption. Compatible with Caterpillar 3054, 3054B, 3056, and 3056E engines as fitted across a wide range of Cat construction and compaction equipment.\u003c\/p\u003e\u003ch4\u003eCompatible Models\u003c\/h4\u003e\u003cp\u003e\u003cstrong\u003eCaterpillar Engines:\u003c\/strong\u003e 3054, 3054B, 3056, 3056E\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCaterpillar Excavators:\u003c\/strong\u003e 312B L, 312C, 315B L\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCaterpillar Backhoe Loaders:\u003c\/strong\u003e 416C, 416D, 420D, 424D, 426C, 428C, 428D, 430D, 432D, 436C, 438C, 438D, 442D\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCaterpillar Wheel Loaders:\u003c\/strong\u003e 908, 924G, 924GZ, 930G\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCaterpillar Asphalt Pavers:\u003c\/strong\u003e AP-655C, AP-800C\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCaterpillar Forestry \/ Feller Bunchers:\u003c\/strong\u003e 550B, 554, 560B, 564, 574B\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCaterpillar Vibratory Compactors:\u003c\/strong\u003e CB-434C, CB-534C, CB-535B, CP-433C, CP-433E, CP-573E, CP-663E, CS-323C, CS-423E, CS-431C, CS-433C, CS-563E, CS-583E, CS-663E, CS-683E\u003c\/p\u003e\u003ch4\u003eReplaces Part Number(s):\u003c\/h4\u003e\u003cp\u003e1639256, 163-9256\u003c\/p\u003e\u003ch4\u003eAftermarket Interchange Numbers\u003c\/h4\u003e\u003cp\u003e138-2058\u003c\/p\u003e\u003cp\u003eNew aftermarket replacement part - not remanufactured, not used.\u003c\/p\u003e","brand":"Reliable Aftermarket Parts, Inc® -OD","offers":[{"title":"Default Title","offer_id":42452068401235,"sku":"1639256","price":35.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0079\/4060\/3955\/files\/1639256_01.jpg?v=1757698444","url":"https:\/\/www.reliableaftermarketparts.ca\/products\/1639256-guide-ex-semifinish-fits-caterpillar-models","provider":"Reliable Aftermarket Parts, Inc®","version":"1.0","type":"link"}
