CAT 303 CR has the shakes………..

Canuck Digger ยท 2013-03-10 11:36

Hi, So my 303cr was having the shakes, about 60 (clock) hours or so ago. Figured her out pretty quick....., the fuel filters. New filters, problem solved. Pulled her into the shop, drained all the fuel, cleaned the tank, which was clean to begin with, and 60 hours later, same issue, and same remedy to fix it. So, any idea why this is happening.? Use shell diesel, it's not super cold where I am, and haven't had the same issue in the previous 600 hours of operation on same machine. Just carry extra filters now, but would like to know why this is happening.......... Any ideas?

    Is your storage/ transfer tank clean?

    Seems to be. Using jerries for this one. Same ones for a long time. The screen isn't picking anything up and the cans look pretty clean at the bottom. Few floaties, but nothing the screen wouldn't pick up. Maybe just a freak thing, but thought I'd ask......

    Had a similar problem with our old 200. I ended up buying a bunch of little clear inline fuel filters from Napa. A couple bucks each if I recall. Stuck one inline after the tank before the OEM filter and screen where it was easily accesible. Took 30 seconds to change and was much cheaper than an OEM filter, plus one could see inside it. Ran these for a few months until all the crud stopped. Our problem was rust in the tank flaking off under hard digging. The little filters just saved time and money.
