Abstract

Dengan berkembangnya zaman, diamana jenis-jenis transmisi muncul serta memudahkan masyarakat kalangan umum dalam berkendara, terutama di tempat perkotaan yang padat penduduk, transmisi otomatis CVT meruapakan sebuah pilihan yang tepat. Begitu juga dengan pelumasan yang tepat dapat membantu menjaga umur pakai transmisi. Salah satu oli yang dapat digunakan adalah Toyota TMO CVT T-IV. Proses penelitian pada transmisi dilakukan dengan tahapan, yaitu mengatur dengan variasi putaran 1000 Rpm, 1500 Rpm, dan 2000 Rpm dan dilakukan setiap 3 kali percobaan selama 5 menit. Tujuan penelitian ini dilakukan untuk mengetahui perbandingan suhu pada variasi putaran untuk mencapai suhu kerja normal yaitu 40°C. Hasil penelitian peningkatan temperatur pada 1000 Rpm perlu mencapai 8.15°C atau 79.6%, 1500 Rpm sebesar 7.29°C atau sebesar 81.7%, dan 2000 Rpm sebesar 5.27°C atau 85.5%. Kemudian peningkatan oli untuk mencapai tekanan putaran idle pada 1000 Rpm sebesar 110 kPa atau 71.8%, 1500 Rpm sebesar 84 kPa atau 77.28% dan 2000 Rpm sebesar 59 kPa atau 84.4%
