As my retarder is installed on my transfer gearbox PTO, ....

hello,
... cause no place and limiting space for off road if installed in normal drive line for shure!
You are serious to take out more than 1000Nm from gearbox PTO line??
PTO all the time engaged should be the normal situation if using for retarder.
PTO-drive line lubrification, how?

I would´nt prefer any Telma or kloft-retarder.de - better go with jake-brakes apes?
