Cat D3B Dozer hyd lines

[Benco]

I have a 87 Cat D3 Dozer that I took the hyd lines off for the blade to replace them. Now I don't remember how they go back on.and I don't have the old metal lines so I can't trace them. If anyone has the diagram for the hyd lines that tilt angle and lift the blade it would be greatly appreciated

Any chance of a full S/N ? Might be able to find something on SIS with more info.

Also maybe a couple pictures of the area the hoses come from and go to?

When I get to my shop I can tell you more I know one hyd line I'm having problems with is for the tilt cylinder i don't know where they go to maybe you can look at yous an give me some ideas

Looks like my D3 is same vintage as yours. I just replaced all the lines not long ago. Took some pics to help me get it back together but think I deleted them. My manual shows basic connections but no pics.

Its raining here, so when it stops I can gab the 9/16 and remove some covers to take pics

Thank you for taking the time out your day to take them pics . Did you replace all your metal lines with hyd hoses on the frount if so when you put the covers on did you have any places where they rubbed.

 

[AllDodge]

No, only replace rubber with rubber and metal with metal. Where the tilt go from rubber to metal and back to rubber (the Vee) I added rubber hose around the Vee and Tie wrapped in place

 

[Benco]

Can you tell me where #1 hyd line on the tilt cylinder goes. I'm having problems with that one. I uploaded a pic you sent me so you know which one I'm talking about.

 

[AllDodge]

On the other side there is a fitting for the 2 lines. They are one on top the other. That one goes to the top fitting. the purple 1 in my pic

 

[Benco]

Ok I got it thank you. Now that I changed those lines do I just bleed them 1 at a time?

 

[AllDodge]

They will self bleed. Just run them back n forth a few times
