Iro tensioning vhiri rinonyanya kuumbwa negomba rakagadziriswa, tensioning arm, vhiri muviri, torsion spring, rolling bearing uye spring sleeve, etc. Inogona kugadzirisa pakarepo simba rekusimudzira maererano nekusimba kwakasiyana kwebhanhire, kuitira kuti hurongwa hwekutumira huve hwakasimba, hwakachengeteka uye hwakavimbika.
Gumbo rekusimbisa chikamu chakapfeka chemotokari uye zvimwe zvikamu, bhandi rine nguva refu iri nyore kupfeka, bhandi groove richikuya rakadzika uye rakatetepa rinoratidzika kunge rakareba, vhiri rekusimbisa rinogona kugadziridzwa otomatiki kuburikidza neiyo hydraulic unit kana damping chitubu zvinoenderana nekupfeka dhigirii rebhanhire, uyezve, iyo inomhanyisa isingaite, inotsvedza vhiri inogona kudzivirira.
Ivhiri rekumanikidza nderechirongwa chekugadzirisa, icho chinowanzoda kutsiviwa kwe60,000-80,000 makiromita. Kazhinji, kana kuine ruzha rusina kujairika kumberi kweinjini kana nzvimbo yakamisikidzwa nechisimba chekutsikisa vhiri inotsauka zvakanyanya kubva pakati, zvinoreva kuti simba rekumanikidza harina kukwana. Zvinokurudzirwa kutsiva bhandi, tensioning vhiri, idler vhiri uye jenareta vhiri rimwe chete kana yekumberi yekupedzisira accessory system inonzwika zvisina kujairika pa60,000-80,000 km.
