Pressure washed this D4 and when finished i started the pony flipped the compression lever and had one of those gut feelings, so i shut the pony off as quick as possible.
It came to me what the gut feeling was and peeked to see if the rag i stuffed in the intake was still there, it wasn't:eek:
Found the rag in #3 cyl barely caught in a valve. No harm. Don

I have learned to always use paper towels for plugging intakes while washing, grinding or doing anything that may contaminate the engine. If the engine is started, the paper towels will be "digested" by the engine and will blow harmlessly out the exaust. Nice looking D4. What is the serial number? Where is the insulation and heat for the shop?

good picture. does anyone know the purpose of the fuel filter housing
side plate (4f5142) Is it just a cover for the casting and occasional
clean out? I have not been able to determine how coolant circulates
around the filter.

About 24 years ago I helped one of the old timers about here rebuild a D8H powershift tractor-he would stuff bits of rags up all orifices. So when building up the engine near pandemonium broke out when he could'nt remember if he had pulled the rags out of the oil pipes-this was followed by spanners flying everywhere as he pulled the pipes-sure eneogh the rags were still in place.
Our man breathed a sigh of relief along with the explanation he had once built up a D8 and forgot about the rags until she started to seize on a hillside in Monaghan!!!!

Hi waukman,
The fuel rack stop and torque spring lives behind the 4f5142 cover.
On industrial engines and gen sets they often have a shut down device mounted to this opening. see pic.

As far as water circulating for the fuel tower, it doesn't. This was another of Cat's follies that just wound up being a sediment trap and high corrosion area. Later engines did away with the water connection and just left the fuel tower mounting flange which became a mounting point for a flimsy fuel pressure gage mounting that faced the driver instead of out the side.

CL Bos Serial # is a 1735. Insulation? the barn is on the ranch i work for and was built as a horse arena, it is now a tractor barn/loading area for apples during harvest. Didn't want to go across the muddy yard to the shop so figured i would paint it in there, plenty of room.
Niel D, thanks for the story, wouldn't have wanted to pay the bill on the 8.



Thanks, Don

This reminds me of a story, back in the '60's, when a newly rebuilt D8H engine lost oil pressure. . We found a piece of paper in the suction screen, it just happened to eb a payslip with the owners name still readable!! and we made a note of the overtime earned rebuilding the engine.

Did the same thing on one of my D2s last year. It actually started but wouldn't run good. I got lucky with a piece of brass welding rod and got the rag out.

One time at the dealer a D4 tractor I believe it was came into the shop for a leaking final drive bellow seal.When the guys drained the oil out of the final drive housing it was an awful looking mess.Here the owner put some old newspaper material in the drive & let the paper & oil homogenize itself together & the paper was ground up real fine from the gears. It sure was a mess to clean out of everything in the final drive, thanks for the steam jenny.That was a first & never saw one after that one.He put the paper in to slow down the oil leaking out of the bellows seal to the outside.

I knew i wasn't the only one, can't remember doing this before, or if i did there were no consequences. While we are on the subject, any more rag or paper restriction horror stories out there? Here is the D4 as of today. Ran out paint
Thanks, Don
