Folks 

I came across what I consider to be one of the best posts tot the list in my 
saved files on the HD. I get the list in digest form these days and I 
noticed very little activity- so I though I'd post 
one thread I thought may be one of the best stories - I'd seen on ATIS. 
I'll do it one a day for the five days-unless Karl Olmstead has objections. 
Karl has a real way with words- and he did/does neat stuff! 

Here is the first installment - Karl -Let me know if you want me to stop!

Should be an interesting weekend. As most of you know, I bought a D8 Cat 
that was advertised on ebay a couple of months ago. Price was right; less 
than I usually pay for worn-out Cubs. It's near Modesto, CA, about 320 
miles from me. Owner says that both engines (starting and main) start and 
run well. Total weight is easily 40K pounds, so with Richard Walker's help, 
I found a trucker to haul it for me. Name's Charlie, he's an old 
catskinner.. ideal for this job. 

The previous owner, who lives in Utah, assured me that the starting engine, 
a 2-cylinder gas hand cranked gas engine, would start as long as I was 
careful not to flood it. A week ago I called the trucking company where the 
tractor is stored, and they gave me an entirely different picture. 
Evidently the D8 has been sitting there for a year or two, which I didn't 
realize. Although they got it started once a long time ago, since then 
three different guys with Cat experience have failed. According to the 
fellow I talked to, 'It's been here so long that the magneto is full of crud 
and there's no way you're going to get it started'. The PO did mention that 
it had new plugs and wires, so obviously somebody felt that there was an 
ignition problem. 

OK, so I changed my plan. The trucker told me that he had a winch; I 
figured he could still handle the loading, and I'd bury an anchor at my 
place to chain the Cat to for unloading it. I've been corresponding offline 
with John Parks at Western Gear about the matter, and he told me that the 
winch was almost certainly not going to be able to pull the D8 up a 
beavertail or loading ramps. Checked with Charlie, and he confirmed that. 

So, I'm going North tomorrow to solve the problem. Never even touched a Cat 
pony motor before, but I do have the D8 service manual because John loaned 
me his to photocopy. And I bought a D8 operator's manual on ebay a couple 
of weeks ago. 

My current theory is that there's nothing seriously wrong with the starting 
engine. If it's been sitting for a year or two, I'm sure that the gas in 
the carb has turned to varnish. It only takes a few months in hot 
California weather for the gas to go bad. Worse yet, somebody may have left 
the fuel petcock on, so several gallons of fuel may have evaporated from the 
carb. I'll bet it's a mess inside! I'm taking carb and brake cleaner, 
gasket stock, some brushes and safety wire for cleaning things out. 

It's entirely possible that the mag's not sparking also, but I'd bet on 
dirty points instead of some major breakdown. 

I've also gotten some valuable pointers from Bill Strickland, Richard Walker 
and John Parks. It seems that Cat starting engine valves tend to stick when 
the engine isn't used. I'll be checking that. I'll be taking a gallon of 
Kroil along. 

Also 1/2" and 1/4" sockets and ratchet, the usual hand tools, a digital 
multimeter, cleaners, paper towels, a 55 gallon drum to dump bad gas or 
diesel fuel in, fresh fuel, service manual, pliers and screwdrivers, two 
sizes of fuel hose, some brass fittings and a petcock... but no trailer, 
for a change. I haven't driven to Northern California for years without my 
tractor haulin' trailer! Oh, yeah, and a couple of pieces of plywood so I 
don't have to sit on the track grousers while I work. And my Y2K Mr. Heater 
propane heater, to take the chill off when I'm working on all that cold 
iron. 

I won't have much daylight left tomorrow when I get there, so I expect to 
work all day Sunday on the tractor. I may drive back Monday, but since 
Charlie's probably going to show up Tuesday morning, I may just stay over 
and help him load the D8, then follow him down to my place. One way or 
another, I expect to increase the mass of old iron in my yard by about one 
third some time Tuesday afternoon. 

Guess I'll find out whether I'm a mechanic or not on this little adventure!
