DX33 Cold weather filter?

caddison · Jan 7, 2005

Well it was a whopping 5 degrees or so here in NW Missouri yesterday. I went out to warm up the DX33 to move a little snow, after cranking it and getting off to knock the ice and snow I walked around the left side and to my shock I saw a large puddle of hydraulic oil under the tractor. I shut the tractor off and looked it over and started it up again and oil puked out around the filter base. Well come to find out there is a cold weather filter that is to be used when the temp drops below 15 degrees.

I just had the 50 hour maintenance done and the tractor had not been used since. I was wondering if anyone else has had the same issue arise. The dealer had to order the optional $50.00 hydraulic filter to see of this will fix the problem. This will pertain to the TC33 as well.

We have weather in Michigan that is well below 5 degrees. I have not heard of this problem.
What type of oil was put in transmission? You may have a bad filter?
Usually cold weather refers to temperatures below 0 degrees F.
Hopefully some of the NH guys will see this post.

Ron,

The oil is the OEM hydrualic oil. The dealer had a service bulletin in regards to the issue so they must be seeing several through out the dealer network. They delivered the tractor this morning and I used it for an hour or so moving snow and had no problems. I am going to go out first thing in the morning and crank it and see waht happens. It may have been a bad filter.

Never heard of such a problem with respect to cold weather & filters period. Was it a Case filter ? If so maybe that's why they recommended a different filter. They may have found out that for what ever reason (maybe new design) that the one you had was susceptible to failure in colder weather. Good idea by Ron to maybe post this on NH.

PS: Before getting my NH TC35D I was very close to getting a Case DX33. I love the Case line also.

/forums/images/graemlins/cool.gifWhen I had my front snowblower & cab installed a month ago , mech. said to watch for hyd. leak & I may need opt. cold weather filter . So I think it is a system wide feature ? /forums/images/graemlins/confused.gif /forums/images/graemlins/confused.gif Big Question was if we put cold filter on do we need reg back on in spring ? /forums/images/graemlins/confused.gif Maybe could save other filter in sealed bag for all hours be put on in winter? Block heater failed 2nd time I used it but they fixed no charge. Think I`ll hook it to timer and or t`stat to prevent another failure. Very pleased with blower and starts better thaan summer if plugged in few hours (overnight). Hopeing with plugged in , warmed before using , hyd. won`t leak ! /forums/images/graemlins/laugh.gif /forums/images/graemlins/laugh.gif

( This will pertain to the TC33 as well. )

If it pertains to the TC33 it should also pertain to the TC29D. But I have not had any trouble with mine. Now I keep mine in a garage a 45 for the most part but have on occassion left outside overnight but had no trouble there either.

This became a concern with the tractors built 3/2004 and newer with the redesigned hydrualic system it is my understanding the system builds pressure at the filter head and blows the seal out of the old filter during cold weather. This would be a concern on all case and new holland tractors since they are the same with different paint.

newred · Jan 19, 2005

My hyd filter blew seal yesterday upon start up at -2 F . Shold have installed with blower I guess. Would advise anyone else with similar winter temps to do same before making mess in shed & losing oil. DX24E.

I think it has more to do with a change in the hydro filter than anything else. The old (NH)xxxxxxxxx890 filter is NLA and has been replaced by a completely different filter. I am trying to determine why we all should not use the "cold weather' filter year around.

spencer200 · Jan 26, 2005

Well actually the 890 filter has been reinstated under a new number, and the cold weather filter has a 50.00 list price and would scare most people away from using it. I will stand by my previous statement about the system building pressure at the filter head during extreme cold weather situations. We have had many assist issues on this with new holland. We have also had two of the cold weather filters blow out so this is why New Holland believes there is pressure building in the filter head. The latest solution from the service department at New Holland is to put on the cold weather filter and change the oil to F200.

RickB · Jan 27, 2005

I appreciate sharing info. We are all in this together. There is no doubt there is too much pressure in the charge/cooler circuit in cold weather. I will be looking into any changes in that system in 2004. What is the new p/n for the old 890 filter?

spencer200 · Jan 27, 2005

/forums/images/graemlins/cool.gif /forums/images/graemlins/smile.gifDealer tech came out & changed my filter to cold weather filter and filled lost fluid yesterday in my unheated shop at -5 F . /forums/images/graemlins/laugh.gifno charge /forums/images/graemlins/laugh.gif /forums/images/graemlins/smile.gif /forums/images/graemlins/cool.gif Very happy with service /forums/images/graemlins/laugh.gif /forums/images/graemlins/smile.gif /forums/images/graemlins/cool.gif

( Replacement for 890 filters 87300195 )
That's what I thought you would say. That is a completely different filter than the old 890. BY CNH admission will not seal in cold AS WELL as the old 890 filter. Smaller diameter, may well be shorter. Certainly not the same filter with new paint and part number that we have seen over the last 6 or 7 years. Cold weather problems in the filter/cooler circuit have been around since 1320's and 1520's. I spent some time in Parts today and came up with no changes in this circuit since before the DA's came out, at least in the class II's; nothing different beginning in early 2004 except the recent filter change. No one at CNH has a grip on this problem. I reference the Asist Knowledge object concerning high charge pressures on Class II tractors. That is the crux of the problem, neatly sidestepped. We are asked to test at a point OTHER than where the highest pressure in the cooler/charge pressure system exists, and NO ONE has come up with filters/coolers/hoses that will stand the ACTUAL PRESSURES FOUND IN THE REAL WORLD! (end of rant) Spencer, you and I are saying much the same thing. But it sure sucks when an otherwise satisfied customer dumps the contents of his (insert model here) on the floor of his pristine garage floor while he thinks he is allowing his tractor to warm up. These folks are doing nothing wrong, and we are all getting screwed. end of second rant.

spencer200 · Jan 27, 2005

I think they hide some of the stuff in the assist system. I am surprised you cant find any of our complaints and answers from new holland we have six now on these filters and pressure problem. One of them stated that this new filter number was the 890 just from a new supplier. I have had others tell me of problems and gone looking in the assist system for them and dont find them myself so I guess I could see why you cant find the info I am giving you.

RickB · Jan 27, 2005

The way I have Asist figured is this. Any concerns filed by an individual dealer and responses to those concerns can be viewed by the CNH service guys and that dealer only. As concerns become verified and legitimate solutions are developed, they become knowledge objects and are viewable by anyone with access to the system. The guy that responded to you that the 87300195 filter is the same as the old 890 and 770 is flat wrong, and needs to go take a look. You should be able to verify this at your store. This whole issue really torques me because it was a minor problem 8 years ago when I started here, and instead of being long since corrected, it is now a crisis. They need to flow more cold oil through the filter and cooler and be done with it. Smaller filters and low pressure hoses and clamps don't cut it. Using Low-vis oil should be a performance choice, not a containment necessity.

keithym · Feb 3, 2005

Oh great! Just what I needed to find. I just ordered a DX33 with snowblower, it's going to be delivered the day after tomorrow. Does this mean I'm hosed if the temp falls below 5 degrees? Does the "cold" filter solve the problem? Wish I had come acroos this BEFORE I purchased.

thanks

Keith,

The new filter has seemed to have fixed the problem. I am a little miffed that the dealer charged me for the additional $33.00 for the cold weather filter after they drove the tractor out of my yard and left a trail of fluid in the snow that has now discolored my grass which will probably be dead in the spring. I really like the DX33 but wonder about some of these issues.

spencer200 · Feb 13, 2005

Only 33.00 that must be his cost the filter list for around 47.00
If I remember right cost is around 33.00 but he should have been able to get it covered under warranty for you if it has been a problem.

caddison · Feb 13, 2005

The $33.00 was in addition to the price I had paid for the standard filter which was $19.00. I think the invoice was arond $50.00. Just a little stiff I thought. I would have thought that if there was a service bulletin out they would have been aware of this.
