ISUZU 4JA1 Manual Transmission Complete Overhauling 

unang video sir medyo dipa maayos abangan mo nalang sir yung english version...

the seal is just to filter the oil because even if the bearing is sealed the oil still passes inside the bearing which means small particles will not go inside the bearing. dont try to remove the seal it may shorten the bearing life

@@yrhelmechanicalelectrical9113 I assume brand new bearings are filled with grease? Anyway, the problem is uneven lubrication after 5-10 years or so. Some bearings will be filled with oil, some not (one droplet literally is "lubricating" the thing). Therefore taking care (regular oil changes) will not help much in this instance (at some point you will replace the noisy/whiny bearings anyway). There is a weird effect. If you try to "lubricate" any sealed bearing by adding grease (or oil) outside, smearing it and hope that it will get inside, it will be the opposite most of the time - that extra lubricant will suck the grease out from the bearing making it worse. At least this is my experience with other machines than cars/gearboxes (that's new to me, design and maintenance nuances). Electrical motors and so on. Conclusion (correct me if wrong): to some extent this is "normal" (some designs are not perfect, and you will need some repair soon or later, even if you care about gearbox oil).

Same issue sir, ano po unit niyo sir?. Saan po kaya ang shop ni sir?

Palitan maraming ganyan na bearing may number yan ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-s5uptEcWcZA.html

kung gear 5 ang maingay wala pang sira sa mga gear yan malamang diyan bearing sa counter gear o kaya klutch plate pero check mo muna center bearing

tingnan mo kung may kalog ang output shaft mo baka yung bearing housing kailangan mo maglagay ng washer wala naman ibang parts sa 3rd gear gawin mo baklasin mo nalang sundan mo yung procedure sa video nandun na lahat siguruhin mo lang na ok yung lock yun lang naman ang dahilan kung nagrerelease na bago nanan synchronizer. check mo din yung 3r gear bak naman may tama na yung ngipin

@@yrhelmechanicalelectrical9113 ano kaya palitan sa transmission na maugong po 4ja1 engine?thanks po

sa bearing po yan ng countergear kailangan palitan na agad pag nagtagal mapuputol yung countergear mo mas malaki na gagastusin mo sa ngayong mga bearing lang.

tumutunog na yan pwedeng clutch plate dapat pag may tunog hanggat ok pa ang kambio agapan mo kasi bearing lang sa counter gear ang madalas nasisira niyan pero kung pabayaan mo yan madadamay synchronizer tapos mababali ang counter gear mo mas malaki magagastos mo.

pag nabuksan mo kasi saka mo palang makikita yan malay mo flywheel bearing lang o kaya release bearing lang ibaba mo muna transmission mo pero check mo muna ang center bearing yung sa propeller shaft pwede rin panggalingan ng tunog yun

Slmat SA reply sir ibaba ko Po bukas,malking tulong sakin MGA video nyo,sllmat SA advise.. God bless po

mura lang yan maliit lang naman piyesa niyan kung putol ang counter gear mo yun lang naman medyo mahal pero wag kang bibili ng materyales na hardened yun yung mga natitipak mas maganda yung normal lang na bakal mas makunat pagdating piyesa ng transmission.

@@yrhelmechanicalelectrical9113 salamat sa reply po...bale sir yong sasakyan ko po pag start naglalagutok pero pag apakan clutch nawawala..pag pasok first gear or lahat ng gear oag aandar na lagutok na naman..ano po kaya posible sira sir

pag may tunog na ganyan ang transmission ibaba mo na hanggat maaga pag matagal tagal pa yan mas marami na masisira. sa ngayon baka mga bearing palang pag naputol na yung countergear mo mas malaki ang gagastosin mo. madali lang pag bukas niyan kumpleto naman sa video iilan lang piyesa niyan.

@@yrhelmechanicalelectrical9113 salamat sir...nawa lumaki channel po ninyo..God bless
