277 enginge trouble

Shifty · Dec 8, 2009

I had the same problem NOT finding a drain plug. I ended up pulling the fuel sender out of the top of the tank and siphoning out what I could. Then I used the suction hose end of a parts cleaning gun to get the last little bit out.

I talked to finning/cat and the mechanic said there may not be one. I was shocked. Would it be a big mistake to cut a 1/2" hole and install one?

I can understand your shock. I have talked to a couple of mechanics who work for Cat Dealers. They both stated that water and sediment in fuel is one of the leading causes of downtime with heavy equipment. One would think that would require a way to drain off water and sediment. I am glad my 2005 Cat D3G Dozer has an easily accessible drain.

Suck bucket is a great idea. I ended up buying 911 fuel treatment to see if that would help. I filled the fuel filter with it, and added it (50:1) to the fuel tank. It idled rough as before for about 15 minutes then smoothed right out. Full power restored. Hopefully thats the end of my problems. I now just need to confirm the quality of my bulk fuel supply.

If you think that's bad have a look where the computers are mounted. On my 267 they are down under the floor and guess what they get water in them too. I think it's all on purpose. pricks

They want you to experience quality CAT service and support.

Replace the fuel filters,add PS to the fuel tank,and primary filter .Prime it,and try it again.It sounds like a fuel starvation problem.

I'm with you. I had my old CAT 287(same engine) have problems after getting a bad load of fuel. Replaced the fuel filter and we were back in business. The filter did its job!

I had the same problem with 06 277b (starts , runs for 10 seconds, then stumbles and dies). It was a cracked fuel pump housing. I thought it was fuel pump, bought new one. CAT only sold the entire piece (which had filter, housing and fuel pump). Replaced filter, then pump, same problem. Then put it all back on the new housing and replaced the whole thing! Worked fine every since. As I look back on it, I had ran the mahcine into a tree right before this happened, must have caused the crack.
