SMI Rack inner tie rods

[Cornes182Cup]

Anybody know where I can get the inner tie rods for the SMI rack, need to be approx. 335mm?

non cup - anywhere
cup - dealer only

 

[Tony Hunter]

Renault anyway

Cheers both of you, explains why the ones the garage were trying to fit today were too short.

Fred - remember I bought my clio down 27th Sept with the suspension and steering knock and you replaced my bump stops cause they had been cut in half? Fixed the suspension knock, but still got the steering knock.

I have some 500 mile old SMI inner tie rods and track rods ends for sale if you're interested? Taken off a car that I broke for spares, have the receipt for them somewhere also.

182 non cup are genuine only.

 

[Fred@BTM]

^na non cup are available aftermarket

 

[Ianboom]

Euro car parts and lemforder don't supply a non cup 182 inner track rod, have contacted them and they still list one. There may be another supplier somewhere.
Will measure my old ones, but think they were 335 long.

non cup ones are only slightly shorter. there's plenty of thread to use them on a cup and still be safe

 

[Ianboom]

The lemforder ones i got were around 15mm shorter than the originals, lemforder said not to fit them and rule of thumb says 2 x the diameter of the thread is a safe amount to use, i ended up with less than 15mm of thread holding my track tod end on. If i didn't use it on the track or it had narrow steel wheels and a 1.2 engine i wouldn't have worried too much!

6 turns is regarded as "safe"

Blimey! 6 turns on a 1.50mm pitch thread is 9mm, wouldn't fancy that on a fwd or powerful car, makes you wonder why Renault use 20mm of thread??

 

[Tony Hunter]

Be fine, can't go anywhere.

 

[Ianboom]

What if it stripped.

 

[Dan519]

There's plenty of thread, it's certainly a lot more than 9mm. More like 20mm. In general enigineering, the rule of thumb for thread engagement is 1.2 times the thread diameter. Now look at the lock nut, that's a lot thinner so a lot less thread engagement. What do you think will be the weaker point?

 

[Ianboom]

Fred said 6 turns is enough, it's a 1.5mm thread, so that's 9mm. I was an automotive engineer and was taught 2 x thread diameter which is what the 182 uses. Lock nut does that, it's the track rod end thread taking the load.

Before i offend or upset anyone, the above is my opinion and my knowledge! I'm not perfect!!

 

[Ianboom]

Been thinking about this, sure my track rod ends were 14 turns on, so about 21mm which goes with what Dan says, the lemf ones went on about 5 turns hence why i fitted genuine.
