    Hello all, I am fabricating a rocker spindle extractor tool. I am not sure of the internal screwthread inside the spindles.
    I thought it was 5/16-26tpi can any of you confirm this ?
    Thanks.

    5/16 - 26 indeed.
    Use decent steel because the threads are subjected to a lot of force when extracting the rocker spindles.

    Heat around the area of the spindle helps to but of course be careful as there is lots of oul in the area and fire is a possibility. I have the type of tool that jacks the spindle out by turning a nut (mine was made by Wassel and came quite cheaply off eBay) it made short work of pulling out my spindles.

    I had the store bought spindle tool. I use the threaded portion to make a slide hammer. There is a 5/16 hole in the end for a "T" handle. I simply hooked it with 5/16" stock and a 1 1/2 pipe T with a hole in the middle.
    I found the heat around the center area of the head and the pop action of the slide hammer more effective than the puller action and heat.
    Heat was needed either way.

    If you get the right size piece of thread, even a short piece, it can be welded to a rod and fix yourself up with a slide hammer. It can also be used on the advance unit.

    That is the kind of tool I want to fabricate on my lathe.

    Then you are screwing up threads as the footrest stud is 5/16" BSW/UNF and the rocker spindle is 5/16" BSC :roll:

    Once you diassemble a crank, you have 6 rocker spindle tools.

    Unless you are lucky to have aftermarket shafts with a BSF thread :eek: I bought a tool off RGM recently and had to tell Roger his thread was wrong. He then told me about the 80's aftermarket replacements with the wrong thread. I dont recall who it was except they were based in Devon UK.

    That would have been Les Harris then. He had a habit of making things with the wrong threads/hole centres/bearing sizes, etc. Once he'd sold the parts, he'd deny that they'd come from him and refuse to give any money back...

    Does no one use the tool provided by Norton ??? Part number 064298...slide hammer.
    So why are the spidles hard to remove?? Try heating the head first.....that helps......Anyway as the Commando end plates often fail to stop the shafts rotating the spindles are often loose to start with!! The tooling that dinged out the two ears that in theory lock off the shaft was so knackered by the time Commandos were being produced they often failed to stop the shafts rotating!! You do check they fit correctly dont you???????

    I've only ever had 2 kinds -

    1. Still aligned and tight pull to extract

    or

    2. Thoroughly trashed

    That's about a dozen Commandos so far.

    Yes, I recall the name now. Anyway I now have an extractor tool with thread suitable for those shafts :wink:
    And, I see they're still in business. I remember the new Triumphs but never realised the aftermarket side was so big ..and still going.

    Look at our news this month and hey presto: http://www.andover-norton.co.uk/News.htm
    I was fed up with the tool with soft threads that normally lasted at best 4 cylinder heads that has been in the market for many years.

    OK Joe, so we were both fed up with this soft tool, I made my own from a decent grade of steel. It looks almost the same as yours.

    I would like to pick up this thread.
    Does anybody know how long the rocker spindle is?
    For disassembling the Rocker spindle I'd like to make a tool.
    But I'd like to be sure to make the bore deep enough for retracting the spindle.
    Thank you in advance

    Yep, I bought a tool, and stripped the 5/16 -26 threaded piece! But I have to say this was used on a particularly stubborn spindle that hadn't been moved for 40 years.

    I bought some 5/16 - 26 threaded bolts and cut the head off one to replace it!

    Fantastic, thanks.
    My plan: I will cut the head of a 5/16 bolt 25mm long, welding into a M12 rod, bore by a lathe a 14mm hole into a hexagon rod, cut a thread M12 into and so I can pull out the part.
