Finally found another filmstrip & both records covering "Principles Of The Diesel Fuel System". Hopefully it can be of some help to someone when it comes to understanding the fuel system on the early IH sixes. This also covers some of the basics for other diesel engines. Enjoy! Mike

I picked up this IH 3800 Industrial Backhoe Last week.. Doesn't run well. Pretty smokey with strong unburnt fuel smell.. Almost like there is a exhaust valve open.. Have valve cover gaskets ordered so can get in there and check it out and adjust the valves if needed. I just got in the Owner, parts and engine service manuals (D282).. Looking for a transmission manual and injection pump manual and if possible a brake master cylinder manual (MICO) The machine had a fine layer of what I assume is dried oil and dirt which is about 1/8" thick over everywhere under the machine. I've taken a 4400psi pressure washer to it and the stuff is stuck on really, really well.. I started to think it's some sort of undercoating.. I have never seen such tenacious grime is that is the case.. I then went thru and greased every fitting I could find with Mobil CMM moly grease. The paint is really nice and shiny under the stuff. I am in need of a transmission filter and hydraulic filter. Any known dealers for Industrial IH products left? I started a facebook group.. There is nearly no information on these really cool machines..

Are any felpro gaskets currently available?

Does anyone have access to felpro gaskets?

I have a 2656 diesel. It has all ways ran good but the other day it would only rev up to half throttle. I changed both filters the first one was nasty, the second pretty clean. But didn’t help. I flushed the lines, then wound up draining / flushing the tank. It Was pretty bad. ( I don’t know the history of this tractor) I also took the screen out of the pump it was clean. Then replaced the rubber hose from filter to pump. I have good flow of fuel to the pump. It will rev. All the way now but only runs a few seconds then slows till it dies. It sound good while running. I also took the fuel cap off the tank iam at a loss about the only thing left is the pump.

I have a 2656 diesel it has always had to have a shot in the nose to get going. It was that way when I got it. Had the hood off the other day working on lights and fuel gauge, thought I would check out the glow plugs. They whernt even hooked up. Got them wired up. Now it starts great. Lol. Go figure. Just thought I would share this
