TC33-DA Hydraulic Hose/Filter Question

[GreenAcres]

Our TC33-DA is four years old now and has about 350 hours on it. It is hydrostat tranny, 4 wheel drive with a factory installed FEL (14 LA).


The tractor has been a great performer, except for one re-occuring problem.


It seems that at least once a year, we have some hydraulic filter leak, or a hose gets busted, or an "elbow" leaks.


For whatever the reason, we have some kind of hydraulic problem that causes us to shut down the tractor until my husband can replace the hose or filter or whatever.


So he asked me to come here and ask you: Are there better quality filiters, hydraulic hoses, and hydraulic system connectors for the TC33DA, than the ones New Holland sells?


We have always used New Holland replacement parts, and also the New Holland hydraulic fluid to replace the fluid spilled, and still seem to have problems at least once a year with the hydraulic system.


Thanks in advance.


Sincerely,

I can only think of one filter that might leak; that's the HST filter. There is a ruggized winter filter available from NH that can take the pressure in that system (when cold, up to 300 psi). If you can't find the filter at your dealer, I would suggest you go to Messicks.com and look up the winter filter or call them directly by telephone. Neil Messick is a TBN contributor and a NH Dealer. I order all my filters from him. His dealership is in PA and I am in TX, but I can order from him and a few days later the UPS truck rolls up to my door with my "stuff."

Oh yes, the HST filter must be tighter than any normal car oil filter. Tighter is better to keep the seal from blowing out.

On busted hoses, check with your NH dealer or a local hydralics shop about getting 4000 psi hoses. I suspect that the hoses you've blown are the short curl cylinder hoses on the loader. Those are the ones that take the most abuse when doing loader work. They are about 18" long and not too expensive. I have replaced all four of mine and have not had another busted hose.

Leaking fittings...well, how much leakage? I think slight leakage sometimes looks like more because the fitting "grows" a dust "beard." due to the tiny bit of oil attracting dust. If your fittings are seeping and dripping, then they probably need to have some hydraulic sealant or careful application of teflon tape. Just tightening might do the trick. In general, I think every tractor owner with hydraulic fittings has to accept that at some time there will be some leaks. It's just the nature of the "beast."

Hello Mrs. Douglas,

I may be able to help you with your hose/leak problem, but I need more details. Do the hoses just blow, or are they being damaged? What type(thread) fittings are leaking? I think(?) that New Holland has been using Bridgestone hydraulic hoses, which I am not impressed with. Many OEM's use Bridgestone as it is an inexpensive hose and gets them out of the warranty period with few claims. Replacement hoses from many New Holland dealers tend to be Weatherhead. In my experience, you can't get a much better hose. I believe that they get the hose and fittings from CNH and they provide Weatherhead. At least that's what the local New Holland dealer tells me, and they are pretty good people.

How about some pics of the hoses and leaks?

Andy.

The 90 degree oil cooler hoses on tractors below serial number G105215 have been problematic for some time. One good solution is to replace the steel tubes running from the filter and cooler bypass valve to the cooler with the newer style tube that uses straight jumper hoses to connect to the cooler. Parts for this conversion should run about $100. To WCH; these are low pressure hoses connected with common hose clamps. A change to 90 degree molded hoses has resulted in multiple headaches, especially at cold startup in northern climates.

Thanks for the info Rick. I haven't seen any of these yet. When most stuff newer like this breaks, people go back to the dealer.

HI GreenAcres

If these are the hoses that have rubber elbows going to the transmisson cooler there is a kit that is about $100 bucks that solves this issue although New Holland should be send it out as a warranty problem. So if you want to elimate that problem get the kit as it has steel tube that are simple to replace. There is one thing to watch for is as you remove a bolt that holds on one of the old tubes there is a spring there so don't lose it or damage it our you have to get one of those too. Search here for Hydraulic leaks and you can find the kit number and some instruction too if I remember right. I've replaced mind after it blew three hoses and haven't had a problem since.

Good Luck on the change over as you'll like it better than cleaning up after that blown hose.
