I brought home another D4. This time it's a D4C 40A that's going to need some tlc. I'm new to this type of D4 as it seems to be alot like the 7U 6U but not like the D4D. Books on the way via ebay.

That is fantastic Bursitis: What is your serial number? I have 3 C series here, all are 40A prefix; 2 top seat and one orchard.

I call it the Achilles heel of the 330 engine; the long water pump pulley snout...it is long and heavy, and the bearings can get sloppy. Make sure it is nice and tight. Aside from the water pump, I have never had any issues getting parts or have problems with mine. Some will say the C series wasn't any good because it was only produced 3 years... I heard they overheat because of the small radiator...again, many times from the mouths of folks that have never owned one!

Post some photos of your new gem please. Congratulations. JM

Thanks juiceman. The serial is 40A3038 and under that number is a capital C. It appears to have always been direct electric start has the cat straight blade and a 5 shank ripper on the back. The main clutch is oil type and needs adjusted because it doesn't snap over. I suppose the steering clutches are the dry type??? It needs the right side final drive overhauled though. It is a seat tank standard tractor though. I am unfamiliar with the D4C. Your right about that water pump.

Hi, bursitis.

I have had the same problem - found that attaching the photo a second time before trying to post seemed to work.

Just my 0.02.

You have a wonderful day. Best wishes. Deas Plant.

Testimonials

"I also joined a year ago. had been on here a couple of times as a non-member and found the info very helpful so I got a one year subscription (not very expensive at all) to try it out. I really like all the resources on here so I just got a three year. I think its a very small price for what you can get out of this site."
