Product Overview

The 1542919C4 hydraulic cylinder seal kit is a factory-manufactured OEM replacement kit for the backhoe boom cylinder of the Case 580 backhoe loader family. Independent aftermarket catalogs consistently identify the number as the backhoe boom cylinder seal kit: Broken Tractor lists it as the Boom Cylinder Seal Kit for the Case 580K, 580 Super K, 580 Super L and 580 Super M with a 2-1/4 in. rod and 5 in. bore, seal-kits.com carries a dedicated 1542919C4 page for the 580 Super M Case backhoe loader boom cylinder, and Tractor Parts ASAP, Tornado Parts, Messick’s and Yesterday’s Tractors repeat the same boom-cylinder application. The current DJF page titles the kit “1542919C4 Hydraulic Seal Kit for Case Backhoe Loader 580K 580SK 580 Super L 580 Super M,” which does not name a cylinder position in the title, while the aftermarket catalogs reviewed anchor the number to the boom cylinder (see Fitment Verification).

DJF Seals manufactures and supplies the 1542919C4 kit at factory-direct wholesale pricing for backhoe loader dealers, repair shops, rental fleets and fleet maintenance programs.

Verified Application

The following application data was cross-checked against aftermarket parts listings (Broken Tractor, seal-kits.com, Tractor Parts ASAP, Tornado Parts, Messick’s, Kit King, eBay):

Materials, pressure rating, temperature range, exact piece counts, certifications and service life are factory data and are not independently verified for this part number; such claims on the current page are not repeated here (see Fitment Verification).

Replacement Scope

This kit supplies the sealing elements needed to reseal the backhoe boom cylinder of the verified Case 580 machines. Broken Tractor lists the kit as replacing 1542919C4, 1542919C2 and G110583 and cross-references cylinders 144200A1, 310844A1, 378031A1 and 87408036, while seal-kits.com lists the same kit for the 580 Super M boom cylinder. Kit contents vary between suppliers, so the exact component set is matched to your cylinder before shipment.

Fitment Verification

The part number, cylinder position, fitments and dimensions above were cross-checked against the following sources:

• Broken Tractor (brokentractor.com): lists the 1542919C4 Boom Cylinder Seal Kit for the Case 580K, 580 Super K, 580 Super L and 580 Super M, with a 2-1/4 in. rod and 5 in. bore, and records 1542919C4 / 1542919C2 / G110583 as the kit numbers and 144200A1 / 310844A1 / 378031A1 / 87408036 as cylinder cross-references.
• seal-kits.com: dedicated 1542919C4 product page for the 580 Super M Case backhoe loader boom cylinder, confirming the boom-cylinder application.
• Tractor Parts ASAP and Tornado Parts: both list the kit as a Case backhoe loader boom cylinder seal kit and carry the 1542919C2 / G110583 interchange.
• Messick’s (messicks.com) and Yesterday’s Tractors: list 1542919C4 in the Case 580 backhoe boom cylinder group with G110583 as an alternate kit number.
• Kit King (via ubuy) and eBay listings: give 2.25 in. rod and 5 in. bore (eBay also states 57.150 mm rod and 127 mm bore, i.e. 2-1/4 in. x 5 in.), providing the second and third independent records of the dimensions; the Tiantong seal catalog row JIC-1542919C4 records 2-1/4 x 5 as well.
• FridayParts and ReliableAftermarketParts: cross-list the number across the 580SL / 580SM / 590SM family.
• Conflict note: model rows — the current page and title use 580K, 580SK, 580 Super L and 580 Super M, while Broken Tractor adds 590 Super M Series I (before serial JJG099999) and FridayParts lists 580SL, 580SM, 590SM and 590SM+. The exact machine model and serial cut-off differ between sources; verify the machine and cylinder before ordering.
• Conflict note: title position wording — the current page title names no cylinder position, while every independent catalog reviewed states the backhoe boom cylinder. The boom-cylinder wording is used in the copy above.
• Conflict note: “Made in USA” and material claims (NBR / PTFE / PU / rubber) appear on dealer listings and are supplier-specific factory data that is not independently verified; they are not asserted above.
• Materials, pressure, temperature, exact piece counts, certifications and service life are not independently verified.
