I’m following the well worn trail of a g wagon power steering implant. Cos the TGB13 will have a 300tdi engine I have the ps pump sorted and just need the box.
costing a fair bit though. The box was bad enough but the tools I’ve had to buy are hurting the wallet. Two huge sockets, one to get the origional box off the truck and another to get the steering arm off the g wagon.
Pulling the drop arms off was a nightmare. Managed to tear the drop forged steel on my puller. Not up to the job. I bought a 10 tonne hydraulic puller and it was just up to the job. A 15 or 20 tonne puller would have been better. When the drop arm lets go it flys off. Bloody dangerous, I tied the puller to the vice the second time. Well worth doing to save fingers, hands, etc
Also had to buy an internal bearing puller to get the bearings out of the main shaft housing. All in all a lot more than I bargined.
if you are doing this please also note the seal replacement kit for the g wagon box does not contain the main shaft seal. Nuts hey.
You need part numbers A3104600161 and A0169971347
A mate has offered to turn the shaft housing for me. 60mm OD
will be a couple of weeks though (4675)

What is the ratio of the G-Wagon Power Steering box compared to the original TGB?
No sure I understand the question. The original box has masses of turns from lock to lock. The Mercedes is much fewer.
