TMS Steering Rack Alignment Tool Dimensions

[timmo]

Does anyone here have a TMS Steering Rack Alignment Tool?

If so, I'd be super appreciative of some measurements, taken with a caliper:

- overall length
- outer diameter
- width between the two inside flats, on the smaller section

I'm basically looking to machine my own, given these measurements. Thanks in advance!

Bump, took some measurements on my car today (ZHP rack). OD and ID I'm not worried about, but it was difficult to get a good measurement of length so it'd be great if someone could confirm it for me:

Length (critical measurement): ~51.6 mm

OD: 60 mm (or larger, just had to butt up to the rack housing)

ID: 27 mm (has to have a clearance fit with the rack shaft and butt up to the backside of the inner tie rod balljoint)

... and, done. Got a PM with measurements from someone, thanks for the help!

Thanks for sharing. does that mean that if you put two of those tools on the both shafts, the rack will be in the center position?

I believe so, yes. If you had two it'd fully constrain the rack dead centre. The idea is that you put it on one side of the rack, then bungee-cord the steering wheel to add preload to sandwich the tool between the tie rod and rack housing.

Hi, interested in 3D printing my own, just wanted to confirm if these were the correct dimensions you ended up working out? thanks

Whoops just saw this, sorry - I took some calipers to the tool and it measured 51.23-51.28. However as mentioned it isn't quite right as the steering is slightly to one side, but you can work in delta! IIRC I got some measurements off someone else on the forum for the TMS tool, and they mentioned they had a similar offset
