Abstract

Quality Analysis of Original and Non-Original Piston Rods on Two-Wheel Vehicles 4 Stroke Capacity 113cc, piston rods are important spare parts on motorcycles, because their function is to transmit the powergenerated in the combustion process from the piston to the crankshaft on the vehicle. If there is damage tothe piston rod which can cause the piston rod to be bent or even broken, so that it has an impact on thesafety factor when driving a motor vehicle. The purpose of this study was to determine the mechanicalcharacteristics of the piston rod material (connecting rod) of original and non-original products, and tocompare the quality of the piston rods of original and non-original products from two differentmanufacturers. The method used in this study was the ASTM E 3 microstructure test, the SNI 19-0409-1989hardness test, and the ASTM A 751 chemical composition. Metallographic testing revealed that themicrostructure of the original motorcycle piston rod was tempered martensite with a fine grain of 60-80 cm.70%, while the microstructure of the non-original motorcycle piston rod is tempered martensite with 40%coarse grain. Medium hardness test The hardness value of the original piston rod material is 428 HV, whichis higher than the non-original motorcycle piston rod material hardness value of 396 HV. As well as testingthe chemical composition that the value of the element Al contained in the original motorcycle piston rodmaterial is 0.0314% > 0.0184% non-original motorcycle piston rod material in the chemical compositiontesting process.

Abstract

Abstrak Seiring dengan perkembangan zaman, dunia industri saat ini juga telah mengalami perkembangan yang begitu pesat, ini dapat dilihat pada industri yang bergerak dibidang pengolahan kayu, pertambangan, pembukaan lahan, perkebunan sawit, pertambangan dan proyek pembuatan jalan dimana sebagian besar dikerjakan dengan menggunakan alat berat. Maka kebutuhan alat berat khususnya di PT. KOMATSU, UNITED TRACTOR dan juga VOLVO juga semakin meningkat. Salah satu alat berat yang sering digunakan didalam proyek adalah excavator, seperti yang diketahui excavator berperan penting dalam pekerjaan seperti menggali, meratakan tebing, mengangkat barang, dan lainnya. Yang bertujuan untuk Menghasilkan ketahanan seal pada batang hidrolik excavator dengan tipe EC200D. Adapun angka yang diperoleh Seal Oli 1 warna putih 1.766,639 kg, Seal Oli 2 warna biru 441,484 kg, Ring Wear 441,484 kg, dan Lip Seal 993,69 kg. Kemudian akan dilakukan pengujian ketahanan pada seal batang hidrolik jika masing–masing seal diberikan tekanan dengan beban 40 – 90 Shore A. Kata Kunci: Ketahanan Seal, Batang hidrolik, Excavator EC200D, Hidrolik Excavator, Silinder Bucket. Abstract Along with the times, the industrial world today has also experienced rapid development, this can be seen in industries engaged in wood processing, mining, land clearing, oil palm plantations, mining and road construction projects where most of them are done using heavy equipment. So the need for heavy equipment, especially at PT. KOMATSU, UNITED TRACTOR and also VOLVO are also increasing. One of the heavy equipment that is often used in projects is an excavator, as it is known that excavators play an important role in jobs such as digging, leveling cliffs, lifting goods, and others. Which aims to produce seal resistance on excavator hydraulic rods with the EC200D type. The figures obtained are Oil Seal 1 white color 1,766,639 kg, Oil Seal 2 blue 441.484 kg, Ring Wear 441.484 kg, and Lip Seal 993.69 kg. Then a resistance test will be carried out on the hydraulic rod seals if each seal is pressured with a load of 40-90 Shore A. Keywords: Seal Resistance, Hydraulic Rod, EC200D Excavator, Excavator Hydraulic, Bucket Cylinder.
