Upper shaft keep falling down.....

Need suggestions on how to fix my Explore's locking mechanism for the upper shaft. I have checked the pin and it's inserted all the way in. I tried to wrap some tape around it but it still slips out. Any help would be appreciated.
 
If you have a XS model it could be the cam lock has given up.
This should not happen with the MKII as the design and camlock material is different.Jerry. <img src="/metal/html/wink.gif" border=0 width=15 height=15 alt=";)">
 
send the upper rod only to Las Vegas they will make a dimple on it.
 
How old is your explorer, the earlier models suffered with faulty plastics and they were prone to cracking in the area you describe and caused similar problems. If it is a fault with the construction, Minelab should repair it free of charge???
 
on my second Explorer (purcahsed NEW from a dealer November 2001).
If it helps to know, this was for what is the latter revision(20 September bios readout at startup on display)of the Explorer XS(THIS IS NOT AN EXPLORER 2).
If your Explorer has NOT had the problem relating the cracking plastic around the cam lock down pin in the control box addressed and you don't get that fixed, then you may have to rely on "jamming" the upper shaft in with some tape or "shimming" wrapped around the control box insertion end to increase it's girth or find another way of fixing it in. The "dimpled" shaft solution does sort of help, but if the plastic is cracked then the problem is only partially and not really "fixed". Believe me, you do NOT want that shaft to pop out when you are swinging a heavier coil like the 15 WOT or even the stock coil to come out when you are least expecting. The combined weight of the lower, upper shafts, X-1 mounted on upper shaft and larger coil MAY( like it did to me ONCE <img src="/metal/html/cry.gif" border=0 width=40 height=15 alt=":cry"> ) pull the coil connector OUT of the control box. You will have a very big problem at this point.
Minelab supplied me with a new shaft:
Difference between the new shaft an the "old" one:
1: NEW shaft is proportionately larger. It has to be because it is now a tight fit.
2: The end of the new upper shaft that gets inserted into the control box is cut at an angle JUST like the upper shaft for the Explorer 2. This I am told is because:
a) To fit into the control box end and take advantage of the way the upper shaft should really fit into the control box end.
b) I suspect also that in order for the shaft to slide in to what is now such a tight space it has to be cut on an angle to allow an easier insertion.
It does seem to me new upper shaft supplied is NOT a converted old shaft. There is absolutely NO slab or movement at that point like there used to be.
3: The cam lockdown on the lower shaft end uses a different colored material on the INSIDE. That is the plastic material that gets locked down onto the lower shaft is RED colored and I suspect it is a different plastic material.
Since I have had this new shaft all has worked well and the upper shaft no longer slips out. <img src="/metal/html/biggrin.gif" border=0 width=15 height=15 alt=":D"> <img src="/metal/html/biggrin.gif" border=0 width=15 height=15 alt=":D"> <img src="/metal/html/biggrin.gif" border=0 width=15 height=15 alt=":D">

I bought this second hand early last year. I checked the start up reading and it reads Sept 20, 2000. If I'm understanding you right, I bought an Explorer that's prone to cracking in the area of the cam lock down pin. It doesn't seem to be cracked and the shaft wasn't slipping out when I first bought it. It came with the X-1 and I just bought the WOT coil and tried to use it this morning. I had to go to my back up detector because the coil was just to heavy and the shaft kept slipping out.
If I buy a new upper shaft will that prevent the cracking problem that might occur?
Thanks,
 
the cracking problem is solved, what he is saying is you should get the new style upper rod cut at an angle.. they run 30 bucks, but Minelab may re[place yours with the new style if you call them
 
I called Minelab, in Las Vegas (702-891-8809), on July 18th, regarding a loose upper shaft on my XS. They said that some units have control housing made of faulty plastic that crack around the retaining pin. The upper housing should be sent to Minelab for replacement and should take about two weeks.
