Injector Removal!! Using The Correct Tool!

Injector Removal Can Get Complicated

If y'all landed on this page because y'all saw this motion-picture exhibit of Facebook as well as wondered if in that location was a level behind it..... Yes in that location is! If on the other paw your looking for data on 'Injector Removal' then your also inward the correct place!

I'm going to preface this yesteryear proverb that the article relates specifically to the Renault M9R engine. This engine is commonly fitted to Renault, Nissan as well as Vauxhall vans, soundless the theory tin post away move applied to close every Diesel vehicle, on which Injector removal is proving to move tough.

So here's the background.... The vehicle (a Vauxhall Vivaro) was brought to the workshop because the engine administration calorie-free was indicating a fault, also the engine was misfiring. H5N1 quick code read revealed mistake code P0204, tests were carried out to ensure the wiring as well as ECU indicate were non at fault as well as nosotros speedily established that the seat out four injector was indeed faulty. 

We had exclusively simply carried out a elementary Injector replacement on a Vivaro that was a yr older than the electrical flow 1 inward the workshop, it was assumed that this would evidence to move simply every bit simple. Well nosotros was either simply incorrect or plainly stupid!!! 

Now I bring witnessed about conventional methods of Injector removal, as well as about less conventional. Anyway methods tin post away include:

• Using an Injector Slide hammer kit similar this 1 Injector Removal Slide Hammer Kit  

• Disconnecting the Injector wires, slacken the clamp as well as plough the engine over. This uses the engines ain compression to loosen the Injector as well as brand removal easier. (Not Recommended)

• Using the method higher upwards but leaving the Injectors connected, as well as thus running the engine to loosen the Injector. (Not Recommended)

• Soaking the Injector inward a core designed for to breakdown corrosion (think WD40). Leaving to soak for an extended menses as well as and thus trying again.

• Making a puller as well as using the puller to withdraw the Injector.

The agency I commonly withdraw a stuck Injector is a combination the kickoff as well as forth methods. This though is non possible on about solenoid as well as piezo Injectors. So I resolved to making a puller soundless without quick access to high tensile threaded rods this proved to be unsuccessful.

After exhausting diverse methods, it was fourth dimension to pass about cash. The kickoff tool purchased was a Sykes Pickavant Universal Injector Removal Pulling Kit. We purchased this amongst the pump, inward total costing circa £1,500. See hither Hydraulic Injector Removal Puller Kit. Initially our supplier was out of stock as well as this needed to move ordered in. We waited.... It in conclusion arrived a few days later. The kit was eagerly opened, similar an early on Christmas acquaint nosotros got rather excited to elbow grease this tool out! (Sad I know but every bit a Mechanic nosotros await forwards to things similar this...) 

The kit was set-up inward minutes as well as nosotros started to force the Injector. Bit yesteryear fleck nosotros applied pressure, stopping to apply impacting blows to the Injector body. BANG!!! We sentiment nosotros had loosened it. Further inspection revealed... Nope.

Top Of The Injector

 We had only succeeded in removing the Injector pipage plumbing equipment as well as destroying our chances of removing the Injector inward 1 piece. This unfortunately was the limitation of the Sykes Pickavant kit which yesteryear the agency was non-returnable in 1 lawsuit used. Back to the drawing board, nosotros came across Darwin Diesels. They claimed to bring the kit specifically for M9R engine Injector removal. See hither Pichler Injector Removal Kit From Darwin Diesels

Again costing inward excess of £1000 for the total kit, it was non ordered lightly but the guys at Darwin Diesels seemed confident inward the kit as well as fifty-fifty supplied total instructions explaining amongst pictures how to withdraw each business office of the Injector if it breaks inward close every conceivable place. The kit arrived as well as it was fully loaded amongst everything from the hydraulic cylinder which conveniently was compatible with the catch from Sykes Pickavant. In-fact hither is a picture.

Injector Remaval Kit

Unfortunately this Injector was stuck thus bad that it fifty-fifty pushed this kit to the limit. First when trying to unscrew the Injector torso from the nozzle it snapped level amongst the rocker/cam cover. Using a big drill fleck though nosotros were soundless able to utilise the thread cutting taps provided inward the kit to drill as well as thread the Injector body, using the puller to withdraw which ever business office wanted to come upwards out at the time. We would as well as thus repeat the process... Removing the Injector inward many pieces then next the detailed instructions, to successfully remove every unmarried business office of an Injector that seat upwards a adept fight, but 1 it was never going to win.

So in that location nosotros bring it... The level of the picture! 

Hopefully the moral of the level came across but just in-case it didn't.

Using the correct tool doesn't ever relieve y'all coin but it volition relieve y'all time. For representative y'all tin post away non withdraw the cylinder caput on many engines without kickoff removing the Injectors. 

Got whatsoever tales of Injector removal yourself. Tell us inward the comments below. I would dear to take heed them. Also if y'all bring whatsoever ideas on how to instruct the £2500+ dorsum to encompass the terms of tools?
