MG MGA - Crank Handle Pin
With the installation of my supercharger,I have found it a bit more difficult (too much stuff in the way) to turn the engine over by hand as before. Therefore I plan to FINALLY build a crank handle for this purpose. I plan to use stainless steel bar (as it is plentiful and quite cheap) for the job, but I'll get whatever I can find that is suitable.
Thanks to Gordon Harrison I have schetches and most the dimesions. What I seem to be missing is the pin dimension at the end. My plan was to press fit a hardened roll pin.
Alternately, I could just use a long ratchet extension on a socket if I could get it on the dog nut. That's 1-1/4" if I remember correctly. Which I probably don't.....
|Tom, I've looked at my crank handle and the pin at the end is 0.225" diameter, length 1" and the hole centre is about 0.45" from the end of the 5/8" diameter bar, which, incidentally, is heavily chamfered. It is not an original handle but ex Moss a few years ago. The pin is a roll pin. Mike|
|If you need it I have the crank handle dimensions courtesy of John Progress who contributes to this site (email me). I built one from his dimensions and it worked a treat.|

|The original crank from my 1600 had a solid dowel pin. It was pretty beat up after decades of use. I'd press in a hardened dowel pin vs a roll pin. Either way, it still never fit the car due to several front end altercations with other vehicles...|
|Well I went to the local home store and found a 16mm x 90mm mild steel bar (has a hook end) for about $6 and some roll pins for about $1. Drilled a hole 1/2" from the bottom and we now have a makeshift starter handle.|
It worked fine for cranking over the motor to adjust the valves. Soon when I get access to a torch I will bend it per the measurements. I think will also replace the roll pin with a solid one.
Mike, I have some dimensions but would gladly accept your information if you don't mind.
|My Moss handle came with a roll pin. After a couple of years of minimal use, it began to slip out. I brazed it in place and have had no more problems with it. |
If you want I can look for a used part in Beaulieu in Sept. as I am going to Tokyo directly afterwards on business and could have it in my luggage (1 week size).
