Tightening Torque - How do I measure this?

[ILuvDetailing]

For the Spark Plug It says 19.6 - 29.4 N-m (2.0 - 3.0 kg-m, 15 - 21 lb ft). How many revolutions is this? Thanks in advance.

you need a torque wrench

[ILuvDetailing]

Ok... thanks. Any other alternative? Maybe I can measure it by "feel"?

[enot]

yup, pwede tantsahan.

i work with car manufacturing before. ang standard, we use click torque wrench for all fasteners. kung wala kang gamit (click wrench or dial torque wrench) tantsahin mo na lang. when you feel na kumagat na yung last thread nya (using a wrench ha, not a hand tight), ipihit mo pa ng about 15 degrees. pwede na yun.

[Skywalker]

yup, pwede tantsahan.

Guilty din ako dito pero ginagawa ko lang ito sa MC ko (diesel ang cage ko kaya walang sparkplug). What I do to avoid over-torqueing is to hold the wrench in the middle of the handle.

I won't advice it though. Malakas lang ang loob ko sa MC ko kasi mura lang ang cylinder head at kaya kong palitan by myself in case masira ko.

I'm also planning to buy a torque wrench.

pag sparkplugs, ilan degrees after you hand tight it? In caltex MIA they use a machine (don't know what its called) to tighten the sparkplugs so I can't see how many degrees. Thanks.

If you really need to check or replace the sparkplug yourself, I suggest to invest on a good torque wrench. Marami pa namang ibang gamit ito beside the sparkplug replacement. Warning, madaling ma-loose thread ang aluminum cylinder head.

may be they use pnuematic or electric power tool to do the job.

use your wrench or special tool na meron ka in tightening the sparkplug. when you feel na lumalaban na yung spark plug thread sa cylinder head (using your tool not just a hand tight), just add 15 degrees turn. same thing applies sa mabababang torque na fasteners. pag higher than 30Nm nagdadagdag na ko ng ilang degrees pa to meet the torque requirement.

kung geographically near lang tayo, pahiramin kita. but i live in the northmost part of M.M.(and i think south ka).

Suggest ko din torque wrench. O kaya avoid overtorquing na lang. Medyo critical area iyang kabitan ng spark plug. Kapag nagkamali ka diyan, nakupow!

[ILuvDetailing]

How much would a good torque wrench cost? Any shops you can suggest where I can buy this? Brands?

Yup am planning to replace the plugs by myself, pag sa caltex its 500 for the service and di sila gumagamit ng torque wrench by feel din. Sayang din yung 500. I just got hold of a detailed e-manual for my car, so I planning to do some of the maintenance myself.

Warning, madaling ma-loose thread ang aluminum cylinder head.

mmm... eto ba yung kabitan ng sparkplugs? Thats why am inquiring so that I can prevent or minimize mistakes.

Where did you get your torque wrench?

Thanks for the replies

[niwde11]

marami dyan. sa may handyman(Robinsons) meron ako nakita. kakukuha ko pa lang yung sakin sa True Value(Shangrila) at aound 1thouplus. meron ding cheap for a little more than 500(i think). di ko pa nga sya nagagamit.

niwde11: Thanks.

Have another question if you don't mind... when do i start measuring using a torque wrench? after hand tightening it? thanks again.

pag nakita mo yung actual torque wrench, magegets mo kagad kung paano gamitin lalo na kung yung cheaper one. me dial sya na nakasulat kung ano na torque mo.

[garyq]

just use the t.w like a normal wrench then see the torque building up as you tighten the bolt. may needle indicator yun (the cheap version) that will deflect up to the actual torque being applied to the bolt.

[ILuvDetailing]

ano difference ng cheaper sa mga mas mahal? Ok na ba yung mga cheaper models? Exact ba yung measurement or may adjustment?

[niwde11]

medyo simple yung cheap. me needle sya pointing sa amount of torque. pag tumama na sa torque desired, ok na. yung mas mahal, yun yung na seset ang torque at pag reach na yung desired torque, me madidinig kang "click". so hindi mo na dapat tingnan yung dial habang nagsisikip ka(mahirap to pag mataas yung torque). wait ka na lang ng click.

[ILuvDetailing]

How much is the price difference? mmm... looks like shopping time again.

[niwde11]

twice, hehehe.

Iluvdetailing gawin mo style ko. Pagpihit ng rachet paglumabas ang isang ugat ko sa kamay, ok na. Pagdalawa ang lumabas, over torque ka na. Pa-calibrate mo nga lang ang ugat sa kamay mo.
