TR4/4A TR4 Steering Rod Splines

I'm sorry to report that once again I had to try to improve something.

The splines on my steering rod appeared rusted and caked with dirt, and I was concerned I'd have corroded, rusted steering rods that eventually would be a problem.

So, using a little puller, I pulled the female splined parts off each rod end, and cleaned both ends with a stiff brush and some lubricating oil.

Now they look nice, but they seem too loose. They slide apart until stopped by the little thru-bolts.

There seems to be some slight play in the fittings as well, maybe a few 1000s.

Is the sliding normal, acceptable? Do I now need to try and pinch those splined fittings so they fit more tightly, or is there supposed to be some clearance and play in the splines.

Thx

Just a guess, but I don't think you want any play at all there. For one, that is the ground path for your horn. And more importantly if there is play in the long term there will be increased wear and that is an area you don't want to fail. Any chance you can put in a grade 8 pinch bolt and tighten them back down?

Definitely pinch them until they lock. If all else fails, add something like Loctite RC609 to lock them.
