1. Tsheb cav:

Camshaft, crankshaft timing pulley, dej twj tso kua mis, roj twj tso kua mis, lub ntsiab thiab tsav lub zog, lub ntsiab thiab tsav sprockets, cams, bearing caps, rocker caj npab, bushes, thrust daim hlau, valve guides, intake thiab tso valve rooj zaum, Tsheb gearbox

2. Ntau yam siab thiab qis ceev synchronizer iav hubs thiab cov khoom siv, clutch gears, cams, camshafts, sliders, hloov levers, bushings, qhia blocks, synchronization rings, maus taus qhov chaw;

3. Tsav lub zog thiab cov khoom siv, sprockets, pib claws, ratchets, lub hnub qub iav, ob chav iav, auxiliary gears, kis tau tus mob, laub rods, cams, bushings, zawv zawg bearings, centering tes tsho, tsav discs, nce qib Valve rooj zaum, tsheb, maus taus roj twj;

4. Ntau yam roj twj tso kua mis, ntau yam roj twj tso kua mis rotors, cam rings, tsheb thiab maus taus poob siab absorbers, ntau yam pistons, hauv qab valve rooj, coj rooj zaum, compressor pistons, lub tog raj kheej blocks, lub tog raj kheej taub hau, valve daim hlau, sealing rings, ntau yam ncej tes tsho, rotors, kev ua liaj ua teb machinery khoom bearings, thiab lwm yam: distributor gears, planetary gears, internal gear plates, internal gears, ntau yam stainless hlau ceev thiab magnetic ncej.

Los ntawm kev nce hauv kev faib ua feem ntawm tsheb thiab maus taus nyob rau hauv tag nrho cov hmoov metallurgy qhov chaw, nws tuaj yeem pom tau tias cov hmoov hlau metallurgy yog nyob rau hauv txoj hauj lwm ceev-tsim nyob rau hauv tag nrho cov hmoov metallurgy qhov chaw.
