Terex tb60

I purchased this 1997 terex tb60 basket case knowing the basket controls won't talk to the ground station due to water damage... It ran like garbage and it wouldn't run unless you jump the starter and bypass the anti-diesel solenoid on the carb... I replaced the main multiplexer board in the basket and that fixed my control issues. Rebuilt the starter switch and the helac basket rotator... Everything functions except here's my issue:

Problem 1: (keep in mind this still uses 1997 ATF as the hydraulic fluid)

When driving in high speed, the pump makes 2500psi which is in spec, when I flip to low speed to get out of a hole, it only makes 700psi so when it gets stuck and out of torque, you have to go get a machine to pull it out since it doesn't have the balls to drive in low speed.

My question: does low speed on these set the pump pressure to 700psi? I wouldn't think so because when I activate low speed, you can feel the hubs pop free from something and engage what feels like another set of planetaries.

Problem 2:
I'm still gathering info on this, but the boom up, down, swing etc functions are slow as a snail... Even when all the way down. I'm thinking maybe my boom sensors are broken and it thinks it's 60ft in the air

Does anyone have any insight on this?

Any new info on this? I’m having a similar issue with mine amongst others

Unfortunately in the time it was sitting; it no longer wants to move or boom up or out. Something electrical is going on.

So I sold it this Monday it's someone else's headache now.

Darn, I was hoping you got somewhere. I just bought one over the summer that started acting up once it got cold out.
seems like electrical but no diagrams, diagnostics etc are making it challenging and the fact there’s not much if any support for these machines

Don't know whether this will help, but out of curiosity about the machine I did a search and I found PDF's of the operator's manual and also a parts manual online.

Here's the latter, which has lots of diagrams and schematics – https://manuals.genielift.com/parts...rials/terex aerials/parts/17162_aug 2002_.pdf
