1. Afraid of "dirty"
If the parts such as fuel filter, oil filter, air filter, hydraulic oil filter and various filters are too dirty, the filtering effect will become worse, and too many impurities will enter the oil circuit cylinder, aggravating the wear of parts and increasing the possibility of failure; If it is blocked seriously, the vehicle will not work normally Dirty radiator of water tank, radiator of cylinder block and cylinder head of air-cooled engine, radiator of cooler and other parts will lead to poor heat dissipation and excessive temperature Therefore, such "dirty" parts must be cleaned and maintained in time
2. Fear of "heat"
Tanperati piston motè a twò wo, ki fasil pou lakòz surchof ak k ap fonn ak kenbe silenn; Sele kawotchou, kasèt triyangilè, kawotchou, elatriye yo sichofe, ki fasil pou laj prematireman, diminye pèfòmans ak diminye lavi sèvis; Se bobin nan starter, dèlko, regilatè ak lòt ekipman elektrik sichofe, ki fasil yo dwe boule ak dechire; Kote veyikil la dwe kenbe nan yon tanperati ki apwopriye. Si li sichofe, lwil oliv lubrifyan an pral deteryore byen vit, ki pral evantyèlman mennen nan boule nan kote yo pote ak domaj nan veyikil la.
3. Afraid of "string"
Various coupling parts in the fuel system of diesel engine, the driving and driven gears in the main reducer of the drive axle, the hydraulic control valve block and valve stem, the valve core and valve sleeve in the full hydraulic steering gear, etc. These matching coupling parts are specially processed and ground in pairs during manufacturing. The matching is very precise. They are always used in pairs within the service life and must not be interchanged Some mutually matched parts, such as piston and cylinder liner, bearing bush and journal, valve and valve seat, connecting rod big end pad cover and rod body, have a relatively good fit after running in for a period of time. During maintenance, pay attention to assembly in pairs and do not "visit" each other
4. Fear "anti"
Gasket silenn motè a pa ka enstale ranvèse pandan enstalasyon, otreman li pral lakòz ablation twò bonè ak domaj nan gasket silenn lan; Gen kèk bag piston ki gen fòm espesyal pa dwe enstale ranvèse, epi yo dwe reyini selon kondisyon ki nan diferan modèl; Genyen tou kondisyon direksyon pou enstalasyon an nan lam fanatik motè. Se fanatik la jeneralman divize an tiyo echapman ak aspirasyon, ki pa ka ranvèse, otreman li pral mennen nan dissipation chalè pòv ak tanperati twòp nan motè a; Pou kawotchou ki gen modèl direksyon, tankou kawotchou modèl chevron, mak tè a apre enstalasyon an dwe fè pwent chevron an pwen nan dèyè a pou asire maksimòm fòs kondwi Pou de kawotchou yo enstale ansanm, diferan modèl yo tou gen kondisyon diferan, epi yo pa ka enstale. nan volonte
5. Fear of "lack"
When repairing the vehicle, some small parts may be omitted due to negligence, and some people even think it doesn't matter whether they are installed or not, which is very dangerous and harmful Engine valve keys shall be installed in pairs. If they are missing or missing, the valve will lose control and damage the piston and other parts; The cotter pin, locking screw, safety plate or spring pad and other locking devices installed on the engine connecting rod bolt, flywheel bolt and transmission shaft bolt may lead to serious faults in use once they are omitted; Once the oil nozzle used to lubricate the gear in the engine timing gear chamber is missing, it will lead to serious oil leakage and low engine oil pressure; The loss of water tank cover, oil port cover and oil tank cover will invade sand and dust and aggravate the wear of all parts
6. Afraid of "oil"
The paper filter element of engine dry air filter has strong moisture absorption. If it is stained with oil, it is easy to suck the mixture with high concentration into the cylinder, resulting in insufficient air, increased fuel consumption and reduced engine power. The diesel engine may also cause "flying car"; If the triangular tape is stained with oil, it will accelerate its corrosion and aging, and slip easily, resulting in the reduction of transmission efficiency; If the brake shoe, friction plate and brake belt of dry clutch are stained with oil, it is easy to slip and work poorly, thus threatening driving safety; Greasy dirt on the starting motor and generator carbon brush will lead to insufficient starting motor power and low generator voltage due to poor contact Tire rubber is very sensitive to oil corrosion. Contact with oil will soften or peel the rubber. Short time contact will lead to abnormal damage or even serious damage to the tire
7. Afraid of "washing"
Some novice drivers or repairmen may think that all parts need cleaning. In fact, this understanding is one-sided For the paper air filter element of the engine, when removing the dust on it, you can't clean it with any oil. Just tap it gently with your hand or blow the high-pressure air from the inside to the outside of the filter element; Leather parts should not be cleaned with oil, but only with a clean rag
8. Fear of "pressure"
Si bwat kawotchou a estoke anba presyon pou yon tan long epi li pa vire nan tan, li pral defòme akòz extrusion ak afekte lavi sa a ki sèvis; Si eleman filtre papye a nan filtè lè a ak filtè gaz prese, li pral pwodwi gwo deformation epi li pa ka seryezman jwe wòl nan filtraj; Kawotchou sele lwil oliv, kasèt triyangilè ak tiyo lwil oliv pa dwe ekstrè, otreman yo pral tou defòme ak afekte itilizasyon nòmal.
9. Fear of "near fire"
Pwodwi kawotchou tankou kawotchou, kasèt triyangilè, silenn revètman dlo sispann bag ak sele lwil oliv kawotchou, si fèmen nan sous la dife, yo pral fasil aje, deteryorasyon oswa domaj. Nan lòt men an, yo ka lakòz tou aksidan dife An patikilye, kèk machin dyezèl yo difisil yo kòmanse nan frèt la grav nan sezon fredi. Gen kèk chofè souvan itilize blowtorch pou chofe yo. Nou dwe anpeche liy boule, sikwi lwil oliv, elatriye
10. Afraid of "Repetition"
Some parts should have been used once, but some drivers or repairmen reuse them for saving or because they don't understand the "taboo", which is very likely to lead to accidents Generally speaking, the engine connecting rod bolts, nuts, fixing bolts of imported diesel engine fuel injector, cylinder liner water blocking ring, sealing copper gasket, various oil seals and sealing rings of hydraulic system, as well as pin pieces and split pins at important parts must be replaced with new ones after disassembly; For the engine cylinder gasket, although no damage is found during maintenance, it is best to replace it with a new one, because the old one has poor elasticity, poor sealing and easy ablation damage. It needs to be replaced after a short time of use, which is time-consuming and laborious. Therefore, if there is a new one, it is better to replace it as much as possible
