Oil & Fuel New Problem Oil leak on TN75D

Robert---we have 4 tn75 so far no leaking there...on our nh 4630 we did repair the seal what you are talking about. Its not that hard kind of like a 4x4 truck hub.. just watch how take it apart....should be pretty easy..like its said bearing and seals and if I remember a large oring...also if you have a bearing parts store around check with them first. Replace mind about 7 years ago parts from NH about $300 and from the bearing store about $125 and 2 days waiting...good luck

Thanks. I have never worked on a 4wd truck hub but did look at the parts breakdown on NH's site and it looks simple enough. I did notice the price for the bearings and seal was going to run me around $350. I will check around and see where I can inquire about aftermarket bearings and weigh out my options.

I am curious though, can you tell me more about the tractor in your avatar and possibly post a larger pic of it? Is it one of your TN's? If so it would be only the second one I have seen with rear duals.

here some my NT75 at work we keep one set at all time with duals and another one as needed. We have 14 NH total with the nt75 being the smaller ones and the NW ts110 the largest with 2 of them being set up as duals front and back

Ws using the TN today and noticed a puddle of oil under it when I moved it. It appears that it i scoming from the PTO area. I can not see well because I need to drop the PTO back hoe to see better. Does anybody know how much of a deal it is to replace the seal on the PTO?

Hi Andy,

There is a copper sealing pressure washer for the main Hyd line just behind the seat in the back of the TN75. Do you have a loader on it? I had to replace this washer a few times over the years because when I use my loader and when I'm sat hitting the bucket down on something very hard, it places allot of pressure on this main Hyd line and this copper washer seems to be the weak link that gives.

Hi, I also have a pto oil leak on my TN75D, have been told by the local New Holland dealers that the cab may need to come off to replace pto seal, seems a lot of work for something that wares & needs replacing at some time.
has any one actually replaced the pto seal on the TN75D, and can shed some light on the subject.

Cab doesn't need to come off.
