Hello Robert welcome to YT. I can only hope you left
part of the story out and you changed the filters and
hydraulic fluid. My question would be did you find any
filings in the filters? Often something has went wrong
in the drivetrain and causes filings to be circulated in
the system. This in turn causes the filters to plug and
then bypass unfiltered oil. Then the filings start
scoring up spool valves and bad things start
happening. So I agree with Rod inspecting as needed
while it is apart is almost mandatory. My Dad and uncle
farmed together and back in the 80s bought a used
1070 I want to say it had less then 2000 hours on it.
Well a an engine valve went out. So me and a buddy
who went to Ag Mechanics tech school tore into it.
When we got done it had an in-frame overhaul. Then
got it all together and thought it would be a good time
to change the hydraulic fluid. Pulled the plug no oil
came out. Plugged with fillings. Turned out the
differential had went out.
Edit: Got into my 1070 story and forgot to mention the manuals, I linked those offered by YT! I do not like to mention it here but I will make an exception. If you are okay with a computer download PDF of the manual you can go to a site called Farm Manuals Fast. They have the 1000 plus page edition for about a 1/3 of the price.
