- What I did here seems to have made this HLR shift really nicely. I think this is super important to get correct. Lazy shifts = HEAT. Super fast shifts = Shockloading the entire drivetrain. John Deere was ahead of their time with this transmission design.
Woohoo, another Thursday, another Spaankyvid!
You are an inspiration to the world! Thank you for the education 😊
Seeing how the pressure dumps and charges back up looks like you have a healthy system. Nice work!
Awesome video! Also a pretty good guide for buyers, things you need to look at!
Thank you sir 😎
Good job, don't forget to change the transmission filter by the radiator and fluid.
Thanks for doing the video. I'm not an expert, but it looked like you did everything correctly to me as a fellow owner of a JD450B. I wish my pressure was that good - what transmission oil did you put in it when you changed it? My pump seems to have a lot of wear, but I found that about 0,030" of shim would change the pressure about 10 psi. There was one official JD shim in mine and it measured about 0.025" thick. I used flat washers for shims, and had to sand a couple down a few thousands to hit the pressure I was looking for. On the gear selection (1, 2, 3, 4), the owners manual says to throttle down, then fully depress the clutch to change gears. I know if I don't do this on mine, it will grind the gears severely.
What oil did you use for your transmission I am about to change filter and oil great video bro
I have one of these dozer that looses transmission pressure when it warms up. You can set up the clutch settings just like this video and after a couple hours it will only have 50 psi in Low and Reverse and 80 in High. Seems like a internal leak that worsens with temp but how do I find it ? It has a new set of clutch packs new transmission pump and selector valve assembly. All did not change my problem.
Thanks for the great vid on the 450 clutch.
When you say free play, is that the amount before the clutch actually gets hard to push? Or the whole top to firewall push?
Where is your foot brake lock? Thank you for the Interesting video.
So just a point of interest as I mentioned I have a 73 450c dozer and am removing brush, tree's and dirt on my property and wanted to say after warming up the cat for 10 minutes and pushing brush dirt roots and pushing road for 15 to 20 minutes my trani is just warm to the touch between my feet on the floor,not sure why yours gets so hot so quick,if you would like I could shot a temp with my gun if you would like...Take care...
Where can I get that paperwork you had?
plowing through this thing....too on the nose?
