Cat D4C with D330 Engine New Aquisition Questions

Check the equaliser bar bolts that go into the block , check for cracking around the area on the bottom of the block where they go in

Thats why on the D4D's they put the lift cylinders on the hard nose. Wished the 6U and 7U tractors had an engine frame and hard nose with cylinders.

Check the equaliser bar bolts that go into the block , check for cracking around the area on the bottom of the block where they go in

Would it be a smart move to get a piece of the polyurethane similar to what is utilized in motor mounts and put that between the equalizer bar and block? Just thinking outside of the box in order to prevent that from occurring...

when i bought my 7U the first thing i checked were those bolts--a couple were missing and a couple had dropped into the belly pan because the nuts had become undone.

and my D2 had the equalizer spring sitting on TOP of the horizontal hold down bolts/rollers

Curious as to how many hours your new tractor has. One weak link that I’m familiar with is the water pump pulley; the “snout” is very long and I’ve heard of premature failure. If there is any wobble to it, you may want to keep an eye on it or repair it. People have had machine shops shorten them only to lose the suction effect of the cooling, whereby they had to make a new shroud. Very expensive, as parts are not readily available for the water pump. Overall, I’m very happy with my D4Cs. Enjoy your new dozer. JM

Thanks Juiceman! When I first got the unit I gave the snout a few solid tugs in several directions to make sure there was no shaft or bearing movement. I see where someone online sells them for what looks to be around $500.00, which is pretty pricey for a pump.

Is there a "weep hole" in these styles of pumps? If so where is it located? I haven't had a chance to spray off some of the old grease yet, but wanted to make sure it was "clear" from any old hard grease so I can see a failure coming.

The hour meter on mine reads 373 hours. Not really sure if it still works, as it looks to be ran off a gear, but as I play around with it a bit maybe I'll see it move to 374?
