Where to Find Engine Manual-L275DT?

[gsdave]

I have a service manual and owners manual, but neither one has much information on the engine in my L275. It recently started blowing dark smoke and feeling like its running on two cylinders. The manuals I have don't give me much guidance on diagnosing this problem. Where can I find one that does?

Thanks!

Have you recently loosened the injector lines at the injection pump? If so you may have loosened the delivery valve which will cause the symptoms you describe! Try tightening the fitting below the injection line nut on all the delivery valves .

I have not recently done any work with the injector lines, but I'll check just in case.

As a further bit of information, the tachometer quit working a few weeks before this started.
