D4D s/n 49J 0498

Hi and welcome,
My info indicates it is a 1969 model with D330c engine (4-3/4" bore) @ 65Hp equivalent to a US 82J1 to 800

The 3304 (78P) engine didn't come in until 1973 at which point engines and tractors had different s/n's.

The hydraulic system is supposed to be sealed and makes use of the air cushion to control hydraulic shock.

Yes, the back end had problems leading to:
New final drive gears and pinion
Stronger bevel gear case mounting flanges
Improved final drive inside cover plate

Check for thermostat and its operation first.

Leo welcome mate was down in the downs a couple of weeks ago at the chapter meeting never seen so many toys all in the one spot if all the meetings are like that its worth going along for a look

mate if its running at 65C I wouldnt be to concerned if it was mine as for the rest of it I cant help you much

thanks for the welcome.

After having to top up radiator with 3-4l of water prior to last use, found signs of water in the oil. Didn't notice any overheating and no visible external leaks.

Engine seems unaffected power wise. So my question, would it be safe to restart so that I can drive on/off a tilt tray?

What are the usual suspects in regards this problem with the D330?

I have the service manual D4D Crawler SN 49J & up but the only engine it refers to is the 3304. Is the 330 much different?...as the plan is to remove the head for inspection.

Appreciate any help.

did the oil go in after sitting for a long time or when you have had it running ?

I reckon it would be ok start like it is just wind it over with throttle shut in case there is water in the cylinders less chance hydraulicing the motor with the fuel shut off

On my d4d the liner pitted and let water in oil had to install new pistons and liners

Paul, do you mean coolant/water? Have been running with the oil for about 20hrs. Last use prior to topping up coolant the 3-4 litres was for about 2-3hrs. Before that coolant level at pre start checks was ok.

thanks Catsilver, will do. Might save a lot of blood sweat, tears and $ if that proves to be the problem.

thanks sandcreek, heres hoping that's not the case.

Before you start tearing into the engine, check the water pump tell- tale hole to see if it is blocked, this will cause any water going past the pump seal to go into the sump.

had a look at the water pump but was unable to spot the 'tell tale' hole. Any clues where abouts?
