tik-tik-tik sound

Wala naman major. Lumuluwag lang ang bearing while the engine gets old kaya umiingay. The silent shaft acts as counter weight to cancel the effects of vibration and noise. What i can suggest is check your belt baka tumalon ng ngipin thus rendering the shafts ineffective.

Sir 4JGtoosie,
Palagay ko ay sira na ang bearing dahil na-timing na ulit namin yung belt B. Pero ganoon pa rin. kailangan na sigurong bunutin at palitan ng bearing.
Thanks ulit

[4JGtootsie]

Ok,

Be sure marunong ang gagawa. May kailangan na special tool to pull out the bearing (malalim around 1/2 deep inside the block). Sa walco they sell the friction bearing at 250 per set. I suggest you do it before ka mag change oil.

1/2 ft. deep inside the block ba? thanks

PM me your email and i will send you an engine manual of 4d56. this is through the kindness of Archie Almario who was nice enough to send it to me. Thank You A rchie

ang ingay minsan nasa fan belt rin!

Pag fan belt naman iiiiittttttt. buti na lang may ngipin fan belt ko.

kung properly adjusted na ang valve clearance niya, at may gano'n pa rin ang tunog, hard-starting ba? If in case na hard starting siya, baka may pundido kang glow plug, kasi pag hard starting tapos may tumunog na gano'n masyado malakas ang explosion sa silindro naiipon kasi ang diesel na 'di nasusunog kapag pundido ang glow plug..

[4JGtootsie]

HD,
Email you later.
Diesel will not ignite in any other form but mist injected to air under high compression and temperature. Even the glow plug cant ignite it without air and high pressure at a precise moment in the compression stage. Usually measured by degrees before top dead center

4JGtootsie,

Nag-test ako, tinanggal ko ang timing belt B at pinaandar ko ang engine, nawala ang tak tak sound. Nagpalit kami ng bearing ng silent shaft pero naroon pa rin pagkatapos. Nextjob ay tatanggalin ko ang belt ng water pump pero nakakalagay ang timing belt B, baka sa water pump nanggagaling kasi nung nag test ako ay walang nakalagay na mga belt kundi timing belt A lang. Pinagtatanggal ko lahat ng belt, yung lang timing belt A ang natira.

[4JGtootsie]

Have you tried running the engine na bukas ang Cylinder head cover? Try to chech the rocker arm shaft for looseness. May limang bearing cap check kung magalaw and then torque it accordingly.
The last 4d56 that i did, na loose thread ayon lumuwag at hindi matiming timing.

4JGtootsie at sa lahat ng nagpost ng suggestions,

Thanks for your help. Palagay ko ay na trace ko na ang problema. Tinanggal ko yung wire na nakakabit sa fuel pump tapos sinubukan kong i-crank start continuously ang makina without fuel injection. Nawala ang "tak tak tak" sound, walang ingay sa makina, fuel knock siguro. Ipaka-calibrate ko yung fuel pump muna at titingnan ko ang resulta.

Thanks.

Island Rock,

Congratulations! Bilib ako sa patience and never say die attitude mo.
Kung may problema just post it.
