7. Leka aila Crankshaft sila

Loaʻa pinepine nā mīkini hou i nā kumu penei:

1. ʻAʻole i hui ʻia ka wehe ʻana o ke apo piston e like me nā koi, ʻoi aku ka nui o ka leakage piston apo, ʻo ka cylinder liner cylindricity i waho o ka whack, ʻo ka lua kumu nui a me ka cylinder liner hole perpendicularity i waho o ka whack a me ka piston ʻO ka wehe ʻana o ke apo e hele i ka ʻaoʻao like ma muli o nā kumu like ʻole, ʻo kēia mau mea ke kumu i ka emi ʻana o ka waiwai puʻuwai maikaʻi ʻole o ka crankcase, a ke kumu i ka aila ʻaila crankshaft. leakage. ʻO ka hopena e hoʻololi i nā ʻāpana kūpono ʻole e like me nā pilikia maoli a hōʻuluʻulu iā lākou e like me nā koi.

2. Crankshaft 50_8.os mm puke moʻolelo roughness nui, hiki ke poni crankshaft e hooponopono.

3. Crankshaft aila sila hui skew, keia manawa e reassembled aila sila,

E palahalaha; I kekahi manawa, ʻoi aku ka nui o ka hui ʻaila aila i loko, a ʻo ka leaka ʻaila ʻaila crankshaft ma muli o ka pale ʻana i kahi ʻāpana o ka lua hoʻihoʻi aila o ka uhi kumu kumu. No laila, i ka hui ʻana, pono e hōʻike ʻia ka sila ʻaila crankshaft i ka maka hope o ka uhi spindle 1.5 ~ 2 mm.

ʻAʻole maikaʻi ka maikaʻi o ka sila ʻaila crankshaft, ʻaʻole maʻalahi ka lehelehe, ʻaʻole palupalu, pono e hoʻololi ʻia me ka sila aila maikaʻi. Inā nalo ka puna sila aila a i ʻole ke kumu hoʻohālike, pono e hoʻololi ʻia ka pūnāwai i ka manawa a i ʻole e hoʻololi ʻia ka sila ʻaila hou o ke ʻano hoʻokahi.

5. I ka hui 'ana i ka aila sila, ua scratched ka lehelehe o ka aila sila e ka mua lihi o ke keyway o ka flywheel kī palahalaha ma ka crankshaft, a e hoʻoulu ai i ka aila leakage. No laila, i ka wā e hoʻokomo ai i ka sila aila, hiki iā ʻoe ke hoʻohuli mua i ka ʻaoʻao o ka huila crankshaft i ke kūlana i luna, e ʻoki i ka ʻaoʻao mua o ke ala kī me ka maka kahiko ʻike maka, a hāpai i ka sila ʻaila ma ka lima i ka wā e hoʻopaʻa ʻia ai ke sila aila crankshaft. ua hoʻonoho ʻia i loko, i mea e pale aku ai i ka lehelehe o ka sila aila e ʻoki ʻia.

6. Ma mua o ka hui 'ana i ke sila aila, crank shaft e like me 50-8.o. Hiki i ka aila ma ka puke pai mm ke ho'okahe i ka leakage aila crankshaft. No laila, ma mua o ka hui ʻana i ka sila ʻaila crankshaft, pono mākou e hōʻoia i ka maʻemaʻe a me ka ʻole o ka ʻaila crankshaft coin 50-8.os mm.
