Engine Model Help

Yes, that's a 1961 model with D330T, also known as a D330a engine. Don't know of any in frame kits available but you probably can get most the parts aftermarket and some Cat. I believe you may be able to get a crank kit but haven't looked in years. That engine was a dog and I guess Cat would just as soon forget about it.

Did you stop it in time to save the crank? Pay close attention when ordering crank bearings. Look at part# and any US(undersize) numbers on the back of the old bearings. And be sure to Time the ballancer shafts upon assembley. It's so easy to screw up an engine job and destroy everything.

Have original CAT service manual for D330 engine 56B1 and 57B1 up. $50 shipped to you. In CAT binder, very good condition.

Should be the correct manual for your engine.

There are timing marks on the gears for everything but the fuel pump drive. You can mark that one unless you want to take everything apart. The fuel pump is timed with a timing fixture after assembly of the engine. Fixture holds offset tang in position with engine at TDC#1 on compression. The ballancer shafts turn at twice crankshaft speed and can be timed with a locking bolt in each one, any cyl on TDC and then install the oil pump. Their idler has an odd number of teeth so marks on it don't line up every revolution. The rod that lost he bearing must be resized and all should be.
