Hello from across the pond....
we have in our collection a 1958 Fiat city bus that has a 680 Atlantean turbocharged 11.1?? engine installed around 1973 or so, I am removing the fuel injector pump and injectors for cleaning and I am having a problem pulling the injectors from the engine. Is there a special puller or what can one do to remove the injectors for service?
I am also looking for a source of high pressure injector lines as the one on this engine are rusted and are a bit dodgy. Any thoughts.
I am looking forward to the fuel injection timing thread solving the gentleman's problems as I am sure I will learn something form it.
Thanks, Chadsaw

Thanks, Chadsaw Yes, my workshop manual for the Leyland O.680 engine says "Fit removal tool Pt. No. 267708 and tighten removal screw to withdraw injector". It does not show a photo of the tool. The procedure given is: 1) Remove the fuel drain pipe from injector. 2) Remove clamp and clamp nut from injector. 3) Remove high-pressure feed line from injector. 4) Remove injector end cap. 5) Screw threaded extension of Tool Pt. No. 267708 into injector. 6) Tighten nut on tool to withdraw injector. I do not have nor have I ever seen this tool but most diesels use a "slide hammer" to extract injectors. Of course, you'd need a suitable thread on the shaft to screw into the end of the injector but I'd think that would work well -- but be sure to keep the shaft perfectly in line with the injector and make the hammer strikes in line, also. Also, I don't need injector work now but I sent an email to Feather Diesel in Halifax 01422 387800 www.feather-diesel.co.uk and asked if they did repair work on O-680 engine injector pumps and injectors. They sent a very responsive reply that they had spare parts, tools, and trained technicians to do such work. I haven't actually dealt with them more than this but it seems a good place to start. I've also had Diesel Injection Services in Tolpits Lane Watford Herts recommended to me but I've never communicated with them. Hope this helps, BH NC USA |

On the 680 engine we used dimantled pipe grips under the the fuel extension where the extension passes through the cylinder head and hit the pipe grip with a hammer to free the injector. Or use anything you can to lever the injector up staying as close to the injector body. An adjustable spanner may fit under. I should say a pipe wrench hope this helps

Diesel shops can make up high pressure fuel lines my place of work made them up but sadly all that has gone.
