I don't have a 450 manual so can't be sure exactly what it says or shows. A gauge with a snubber can smooth rapid fluctuations in some cases. Fluid filled gauges can be better as well. If the manual says adjust to 300 psi that would be the ideal (maximum) set point. The adjustment screw may require ...

Welcome to the boards. Don't be surprised to find this moved over to the Late Models Board, this Early Models Board focuses on machines up to the 2010s. There are only a few here that have a machine as new as yours which is a different animal (the drivetrain is different than the 450E and prior). I ...

JD publication TM1102 is the only Technical (service) manual for the 450C the JD Construction and Forestry bookstore shows.

Don't be surprised if this gets moved to the Late Models Board, that is where threads on 350s, 450s, and newer machines belong. Do you have the 450C technical manual to trace the hydraulic system with? Have you done any pressure tests? Looking back at your earlier posts, it appears your crawler left...

Sorry to hear that.

Thanks for reporting back with what you found.

How is the free play for the engine clutch? The engine clutch slipping will show up in the higher gears first.

Thanks for telling what you found. Having the solution posted always helps.

Welcome to the Boards. Don't be surprised if your thread is not here later. 350, 450, and newer machines are handled on the late Models Board. This Early Models Board is for the 1010C, 2010C, and the models prior to those. A Moderator will likely move it when they see it. Just a housekeeping thing, ...

As I posted above "The 450C steering clutches have to have oil pressure to drive, no pressure, no drive. Pulling back on the lever to steer, dumps the oil pressure from the steering clutch." So yes, they are supposed to have pressure anytime the engine is running unless you pull the lever to steer (...

Welcome to the Boards. The 450E originally was a 4276T. As to what pump a 4045 engine needs that may be a question asked at your JD dealer or an injection shop. The 4045D is/was used in many applications with different pumps and settings. If your JD Construction and Forestry dealer has a Repower boo...

I thought you likely still had your old cap to compare. I guess I should have posted these before. You can see the copper pins for the plug wires as compared to the location of the clips and index tabs on the two caps. http://jdcrawlers.lcent.com:8000/johndeere/albums/userpics/10023/Dubuque_2_cylind...

I had a few minutes this morning so looked back at your posts, and I am guessing this is the 450C you posted about before. It is always best to tell what you are working on when you start a thread. The 450C steering clutches have to have oil pressure to drive, no pressure, no drive. Pulling back on ...

Right track on what? I could search your old threads but nothing says you aren't working on a different machine than one you posted about before.

Welcome to the Boards. Just a thought. When you converted to 12 volts did you keep the original distributor cap or change it to the cap often sold as a 12-volt cap? You need the original style cap. The one often called a 12-volt cap is for the Waterloo built two-cylinder engines and the plug wire so...
