MG TD TF 1500 - Skyhook 5 Speed gearbox
|Does anyone know what thread the top of the Datsun 5 speed gear leaver is? To accept a gear knob.|
I thought it was 8mm but a nut from Home Despot is very tight almost to jamming after 3 threads? None of my vast collection of extra nuts accrued over the years fits either.
I would like to drill and re tap an older MG gear leaver knob I have had for years, but it dose not fit this thread.
|Have you tried both 8mm X 1.25 AND 8mm X 1.0?|
|Oh Hell |
I'm an old Brit and metric leaves me cold :)
There are different thread counts for the same dia..?
Do you know if Home Despot or Ace carry both?
|The XPAG is 8x1.0 Bud|
|Yes, Home Depot have 8mm X 1.0 hardware. I know because I worked there up until a couple of months ago, But the fine thread metric stuff is in the metal drawer cabinets, not hanging up in the plastic bags.|
|Well I will go and give e'm a try. Thanks Lew.|
Bud, The gearbox is Datsun so XPAG do not apply :) However I was aware some of the hardware was mad metric. Nice to know it is 1.0 Thanks.
|The 1.25 is actually a courser thread|
The 1 or 1.25 or 1.5 etc is the distance between each thread
As in 1mm pitch --1.25mm pitch etc
Simple measure up of the thread on the lever will tell -----Count ten threads and measure the distance---example
10 threads-if it's 12.5mm then its a 1.25mm pitch-----------or 10mmthen it's 1.0mm pitch
|Metric runs course fine and finer on the pitch count. Plus don't rely on anything in bins being in the right bins.|

When I installed mine I made an extension because the end of the rod was too low for me.
In the sketch the left side (8mm x 1.25)is what screws onto the Datsun shaft.
The right side was for an MG shaft knob (8mm x 1.00).
|Mort, You the Man. I have spent quite some time in the Garage [over 98C] trying to count 10 threads and measure them accurate. All I did was loose a lot off water.... I had resorted to crazy putty and make an impression to do it that way.|
8mm 1,25 is good. Now to find a nut that will fit on it at Home Despot and drill out my MG knob to tap it the same.
M8x1.25 needs a 6.8mm drill for taping. Right?
