Fuel Injectors
« on: June 02, 2019, 11:35:39 AM »
Could anyone advise me where I could buy 4 injectors for my GS Perentie..4BD1. I thought I seen somewhere where Minto were selling new injectors, If there are none available, has any one had injectors serviced? and what is approx. cost. MY Perentie that I have owned for about 6 years and has just over 100000 on the clock runs beautifully, however when I go bush and work hard on tracks etc next morning she smokes badly and runs on 3cylinders for a couple of minutes till it burns of excess fuel. I suspect a leaking injector dribbles fuel in overnight. I would really appreciate getting my hands on some new injectors. Thanks ..Johno

You don't normally need to replace entire injector, just the nozzle, they where about $80 each from any truck / diesel spares.

I'll second that. They are a very simple old style injector that can be easily cleaned and crack pressure adjusted with a screwdriver. Most of the time a tip clean and pressure adjust are all that is necessary.

There were USED injectors coming through the auctions. Good for a reco core, but not new.

Also, try your Isuzu dealer for the nozzles or even the whole injector. Genuine parts are surprisingly cheap for fast moving stock. Isuzu part numbers are in the RPS.

I DON'T HAVE ACCESS TO A PARTS MANUAL.
Yes you do!

On the top right of this page, you will see a link to www.remlr.com.  Go to "The Library" down the left column, then go to "Parts", the "Repair Parts Scales". There's the parts manuals you need, and more!

Oddly, despite being a wholly Isuzu part, there is only a Land Rover number listed for the complete Perentie injector; HYL8706. That is for the 4x4 4BD1, the injector for the 6x6 4BD1T is HYL8645

While the injectors for the 4x4 and 6x6 are different (4BD1 has 5 hole nozzle tip, 4BD1T has 7 or 9 holes), even for the 4BD1 engine there is a staggering array of different injectors available from Isuzu (For example: Genuine Injectors). And the Australian market has different ones again for the Isuzu NPR trucks not listed in that list; 8-94117-023-1 or 1-15300-170-1. What are all the differences? Will they suit a Perentie? I have no idea, so that was why I just suggested a new nozzle and tip to reco your current injectors.

for what its worth my advice is dont try and service them yourself. Its a send away job. It needs to be done in a clean room with some specialised tools to service them properly. Plenty of fuel injection mobs out there that will do them for you.

They are the old standard Bosch injector......you can ,if you wish ,use CAV nozzles meant for a Perkins or a Ford,or Bosch nozzles ,or Kiki nozzles ,they are all made to a standard set by Robert Bosch around 1930.

I bought three sets at auction last year and had one set of 4 re-knozzled and setup by Berima Diesel. Cost was $130 per knozzle for the refurb.

I still have two sets spare. PM me if you would like a goos set of second hand knozzles as spares.
