Glad you have it coming.

069489 is a 1968 serial number. They were built in Dubuque so it should be a T after the digits.

Have you inspected the filter in your reservoir? You need to know the length of the one in it to get a new one as at least the bolt that secures it is a different length for each one.

There is one filter used, located in the reservoir. Two different length filter were used. You will need to open the hydraulic reservoir and see which filter you need. Different hardware is needed for each filter. The hardware can be changed so either filter could be used. I believe you will find it...

Do you have a copy of the parts catalog for the JD 350 Loader, PC926? you need that to find the part numbers for the loader attachment, including the hydraulic components on the loader, such as the control valve. As I posted before, T13132 as an adapter fitting on a 2010 tractor, not used on your cr...

Do you have a 3000 psi or greater pressure gauge? Your service manual should give some testing procedures. If you take the main relief apart you are going to need a gauge to adjust it after assembly. You may need a helper to check to see if the pump shaft is turning when the lever is moved to lift t...

Welcome to the Boards. For a few O-rings you are going to be further ahead to just go to you JD construction equipment dealer and get them, than playing the let's match this up game.

Here is a link to the 450C Bulldozer online parts catalog. https://partscatalog.deere.com/jdrc/navigation/equipment/17466 I do not know if any free downloads of the TM 1102 the 450C Technical (service) Manual. I expect you will need to purchase that one. Lavoy may have it available in his store if y...

Welcome to the Boards. There is an O-ring at each end of the spools and some on the relief valve and fittings. I think the O-rings on the spools should be able to be changed without removing the valve. Do you have the 450C technical manual? Do you have a parts Catalog or use the one online. Those wi...

Doing a part number search in the JD Parts catalog system it appears that swing cylinder was used on at least some of the 9250, 9450, and 9550 backhoes.

Is this the swing cylinder for your 9550 backhoe you have asked about before, or something else? If it is the swing cylinder, have you talked to a JD construction equipment dealer parts guy and asked them to do a system search to see if a dealer somewhere might have one? What salvage yards have you ...

I am going to say what you use for weld filler wire depends on the welding equipment you are using and the base metal. 70 series rod or filler wire is my normal choice. Some may be using 6013, or 6011 as it will run easier if they aren't good at welding or have AC machines. As you say you are a mach...

Welcome to the Boards. In a search of the cylinder number, I find you asked about this same cylinder on Yesterday's Tractors in June of 2023. I don't see any follow up from the suggestions given there. Is your cylinder damaged beyond being rebuilt? 2023 YT thread The search using the part number AR1...

I think there several copies of the service bulletin # 286 about the tool floating around in different threads here. Here is a photo of it.

The voltage regulator should not keep it from starting. Take the wire off the generator armature terminal, that should isolate the regulator if it is bad. I would say unhook the battery wire from the regulator, but I am not sure if the switch is tied to the regulator for power without digging out a ...

Are you looking for a "blueprint of the track frame that would show all the hole locations and thread sizes? If so, that would be something you would have to ask your JD dealer if they can get it from John Deere. Between finding some of the old holes and the holes in the crossbar you will most likel...
