Jason, Jim I apologize I did not see your reply's until just now, for some reason I did not get a notification and I haven't been on since early May. I wanted to update you and say thank you very very much for all the help! My son and I flew out May 4th to remove the engine and torque converter from...

Jim, Yes we did go through this last fall haha, sorry but I have slept a bit since then.. I wasn't able to make it out and pull then engine when I had hoped to last year, so I am gearing up to head out Tuesday of next week and wanted to take the parts with me I could possibly need. I have found ever...

Have you looked at the on-line Deere parts manuals. I’m not a 550G or torque expert. But here is a link. https://partscatalog.deere.com/jdrc/sidebyside/equipment/77456/referrer/navigation/pgId/400930491 Best regards, Bruce Hi Bruce, Yes I have used that, this one however does not show the seal. If ...

Seems I am unable to post photos

Hello All! I am beating my head against the wall, hoping someone out there can help me understand this.... I have a JD550G torque converter machine, it is remote so I am trying to gather all the parts I could need prior to heading out for the repairs. The issues is that its leaking transmission flui...

The balls are replaceable but as you pointed out it isn't an easy task. I have done a few of them over the years and had them removed by our fabrication shop that had air arc equipment to remove the worn ball. The caps are hardened but I have no idea if they are as hard as the ball itself. There ar...

Good morning! Looking for some info on the 550G trunnion, mine is fairly sloppy and will need to be repaired or replaced soon. I am assuming the ball itself is welded in? Are the balls made of a harder steel then the cap? I am wondering if in general a guy could purchase a new cap, remove any shims ...

Jim,

I sent you a PM.

Thanks
Darren

Your 550G is like my 450E as far as manuals go. You need the second technical manual to go with the one you have. TM 1403 is the first of the set. It has most of the operational function and testing information. TM 1404 is the nuts and bolts repair info. https://www.johndeeretechinfo.com/search?p0=...

The inspection plate part number is R121039, it can be seen if you search the online parts manual.

Hi Darren, Hopefully someone who has been into one of these will weigh in, best I could do was look through the on line parts catalog. I didn't spot a plate in the bottom of the converter housing in the parts catalog either. It looks like the converter/flywheel area should be dry. It looks to me li...

Hello All! I need some help on a 550G dozer.... It is leaking transmission fluid from the inspection plate on the bottom of the torque converter housing. It is leaking at a steady stream while working the machine. I am going to pull the engine to fix whatever is causing this issue, my problem is I a...

I need to correct myself a little bit. After I posted that last post I went to the shop and looked at a six cylinder I have apart to look at the front end of the engine. This six cylinder is the same as your four cylinders it just has two more cylinders. I was wrong about you having to swap the ent...

Okay so let me make sure I follow you. The 4039 that you are wanting to use is in a roller and not another John Deere crawler? Maybe you mentioned that and I just missed it. Which given my dumbass factor would make it a great possibility!! :D That being said and in case I did not miss something the...

I don't know if there will be a difference in the two flywheels or not. You might have to swap the flywheels. The parts book shows different flywheels in the 550G 4045T depending on convertor or not. Then the question will be if you have to swap flywheels, do you need to swap the housing plate that...
