i purchased MSC-Competition Metro 6R4 a while ago but have only just got it out of the box to give it a run well thats what i expected to to this is my first purchase away from scalextric or scx and i must say how dissapointed i am the spur and pinion do not mesh how do i fix oh buy a allum key .75 silly money still can not get to work that well as you can only move brass collet not the spur gear has anyone else had this problem out there

Hi Nigel

Away from the mass producers many slot cars use grub screws these days. The 0.95mm is quite common and an allen key is cheaply available at a decent hardware store.

The brass collet is meant to centre on the motor output shaft. The crown-wheel unusual in that it is a separate item but you can move it to set the mesh. It has a small grub screw as well.

For me the separate crown-wheel is a little pointless and over engineered but I suppose you could simply replace it with a Scalex one although it has to be said it does work well once setup.

cheers
Mark

thanks for info have purchased allum key from a well known shop same place that i purchased car from but the .075 only fits brass collet not ally spur gear not sure what to do next if i wish to replace spur still can not get off shop said send back and they would sort out but at my expense on postage

 

[Mr Croker]

I will check the car when I get home but I am fairly certain that all the grub screws on it are 0.9mm M2

Small size as the slot.it - actually they must be as took the car apart with my sloting plus 0.9 torque wrench.

Sure looks like M2 to me.

 

[nigeldangar]

yes but the .75 allum key only fits the brass collet not the one that the spur gear is on that is the one that needs adjustment if i move brass one it rubs on the motor spindle the grub in the ally spur gear holder is not .075

 

[Mr Croker]

Thanks Phil although mine is different to that!!

I think the point is you should have a 0.9mm for both.

There is no 0.75mm and it will round out in them although you could have been lucky with one.

 

[Mr Croker]

Ok.

Got some pictures now

Item in question

Sloting plus SLPL 9105 Torque Hex Wrench 0.90mm - for M2.2 grub screws

and a close up

Hopefully this will help

Although I was wrong about Phil's car. It is the same just a different colour

id just like to point out that a good cheap alternative to those torque wrenches are the wera hex drivers aailable in 0.9mm and 1.3mm and are very decent for the price for those who dont want to shell out the sloting plus/slot.it prices but dont want a stupid little allen key.

my rs200 didnt run great out of the box but with a little love its now smoother than a pint of john smiths.
