PrediksiSoal UNBK Sekolah Menengah kejuruan Otomotif 2019 Paling Lengkap Beserta Kunci JawabannyaIntroduction How to Remove Broken Glow PlugsThe aluminum head 4 valve diesels are notorious for seizing glow plugs. Apparently the plugs don't seat properly at the combustion chamber end. This allows carbon to get packed in around the barrel. Over time the plugs become glued into place. The narrow neck between the hex nut and the threaded shaft isn't up to the task of untwisting the plug and it snaps off. The problem has nothing to do with the threads sticking, though the aluminum steel combination can't be helping. If you have a broken off glow plug, you are faced with a choice A Remove the head and take it down to a machine shop to have the plug machined out - OR - B Make a simple puller to yank out the plug. This page describes how to do B Step 1 Tools, Caveat & Initial Work This instructable is based on my DIY page on removing glowplugs from OM606 heads '''HERE'''. As such, if you are pulling a different plug you will need to adjust the tools and dimension a bit. The basic method should still be gripsdrill motor1cm drill bit 13/32" is just right, 7/16" might be too bigM6 x Tap and drill sethardened M6 x bolt, at least 6cm longhardened M6 nutassortment of washersa 13mm X 3/8" standard depth socketpatience, lots of patience, heads are very expensive replacement partsVice grips will do nicely. This part of the job is brute force. Just tear the off the hex part and then clamp onto the electrode and lever it out. The electrode is a good 4cm long and can be welded in there pretty well. I've had to use a pry bar to pull the electrode out. It has to come out for the next steps. Step 2 Freeing the ThreadsDrill out the threaded portion of the plug. Use a 1cm/.4" drill bit to drill the first 15mm of the snapped off plug. This gets you through the threaded portion of the plug. Now the plug can be pulled straight out, rather than needing to be turned. If you drill straight along the axis of the plug you will leave the threads of the plug in the head. The head will be undamaged. Blow out the 3 Drilling the BodyDrill out the hollow part of the plug with the 5mm drill from the M6 Tap set. Go in at least 35mm and not more than 45mm, as measured from the surface of the head. Blow out the chips. All units measured for 24 valve OM606 engineStep 4 Tapping the BodyUse a tap to make threads on the inside of the glow plug body as far in as the tap will go smoothly. Whatever you do, don't break the tap in there. Take your time. Blow out the chips. picture shows larger tap, use a M6 for this step Again, measurements relate to the OM606 24VStep 5 Building the PullerThread the M6 nut onto the M6 bolt. Then stack some washers on to the bolt and thread it as far as it can go into the now threaded glow plug. Just get it snug, no real force is 6 Pull the PlugTurn the nut clockwise so that it gets further away from the bolt head. This will force the plug out of the head. The first real resistance will be firm. After the grip of the carbon gunk is broken it will move easier. Then it will stop moving. This means that the plug is jammed up against the washers. Unscrew the puller and pry out any bits thread rings, etc that are easily removable. Reassemble the puller with a 13mm x 3/8" socket instead of the washers. The hollow formed by the socket will allow the plug to move further out of the 7 Success!When the bolt head starts to turn, you will have pulled the plug out far enough that you can yank it out by hand. This is what you should seeStep 8 Cleanup & End ResultSuction out the chips. Then, insert some wadded up tissue paper into the hole. Now you can clean up or repair the threads. If you were careful the threads should be good and you can install a new plug. If the threads are damaged, install a Time-Sert or Heli-coil x 15mm. Remember to ream out the glow plug hole Klann KL-0369-13 As an experiment, I've chosen to coat the entire body of the plug with Hylomar HPF. Aside from sealing the nose and threads this sealant is fairly temperature stable and may fill up the space that would otherwise fill up with carbon. We'll see in 50Kmiles or so.

Skip to content Pada mobil dengan ditenagai mesin diesel, akan ditemukan satu komponen yang sangat penting bernama busi pijar atau glow plug. Fungsi glow plug atau busi pijar ini adalah untuk meningkatkan suhu udara yang ada di dalam ruang bakar agar proses pembakaran bisa dipercepat. Perlu diketahui, komponen glow plug ini hanya bisa ditemui pada mobil yang menggunakan meisn diesel. Hal tersebut dikarenakan proses pembakaran yang terjadi di ruang pembakaran berbeda dari mobil dengan mesn lainnya. Lalu, apa beda proses pembakaran dan fungsi busi pijar ini? Dikutip melalui laman resmi Auto2000, berikut ulasan lengkapnya Cara Kerja Mesin Diesel Proses bekerjanya mesin diesel memang berbeda dengan mesin bensin. Jika mesin bensin menggunakan spark plug atau busi untuk melakukan pembakaran camuran udara dan bahan bakar. Maka untuk mesin diesel membutuhkan glow plug atau busi pijar untuk meledakkan capuran dari udara dan bahan bakar melalui tekanan kompresi tinggi dan panas yang cukup. Ketika tekanan panas dan juga kompresi yang ideal sudah didapatkan, maka campuran solar dan udara yang ada di dalam ruang pembakaran mesin diesel dapat meledak dan menghasilkan tenaga pada mesin. Hasilnya pun akan membuat mobil menyala dan dapat digunakan. Dan pada saat proses mendapatkan suhu idel untuk pembakaran inilah glow plug ini sangat dibutuhkan. Fungsi glow plug pada mobil yang menggunakan mesin diesel adalah untuk memanaskan udara di dalam ruang bakar. Tujuannya adalah agar mesin dapat mencapai temperatur pembakaran ideal untuk membakar solar dengan udara yang nantinya menjadi tenaga bagi mesin. Jadi, apabila mobil yang kamu miliki susah untuk dinyalakan, maka bisa jadi karena ada kerusakan pada glow plug yang bertugas untuk memanaskan suhu pada ruang pembakaran mesin. Sebagai tambahan informasi bersama, komponen glow plug ini biasanya dipasang masuk ke dalam ruang bakar. Bagian yang menghasilkan energi panas akan diarahkan langsung menuju ruang pembakaran agar suhu udara di dalamnya bisa lebih cepat panas. Untuk mesin diesel tipe direct injection, komponen glow plug ini dipasangkan langsung tepat di dalam ruang pembakaran yang berhadapan dengan piston mesin. Sedangkan untuk mesin diesel tipe indirect injection, busi pijar atau glow plug ini dipasangkan pada pre-chamber. Dan itu dia cara kerja dan fungsi glow plug yang mungkin pelru kamu ketahui agar semakin memahami komponen-komponen yang ada pada mobil diesel kamu. Semoga bermanfaat. . 241 473 468 498 56 299 322 429
