Hudson Crank Gear

Does anyone have a crank gear part number 66310 that they would be willing to part with (fits the alloy Gear).

Must be prepared to send to NewZealand.  My cost of course.

Thanks.

    Good luck Trevor, rarer than rare, surprised nobody has ever tried to get them made, my Dad did many years ago, but, afraid all gone now and I'm too old to bother.

    I am sure there are still some out there somewhere just waiting for me. we will see.  I recently found a NOS one but need another for one of my cars

    Did you mean 166310?

    Just to clarify, the gear number is 166310.   I can get these made if anyone interested.   The more ordered, the less the overall cost.

    In the US, Ascent Gear Company in North Fl, can make these up. They are just up the road from me. Several years ago I had them make up some Studebaker V8 aluminum cam gears.

    The crank gear is steel, and the cam gear is aluminum. I have photos, but the photo attachment option on this thing has gone away AGAIN. It's easy to see why most of the folks are going to the Facebook HET page, as this one is not too user friendly anymore....
    Well Ken we have a couple of issues on the open forum at the moment that we are working through so hopefully you'll bear with us as we do. The club forum over at www.hetclub.org is also available for use as well if people so wish

    I have a few spare alloy crank gears. I also would like to find a few crank matching gears to make up sets. ozhudson@gmail.com

    To put some numbers to it, early 2015 a CNC gear maker gave me ball park figures to make the aluminium CAM gears, he was thinking AUD400 for the first one and AUD130 a piece after that in batches of 5 or 10. 

    I'm guessing that these figures would also be applicable for the steel crank gears. CNC machining has really opened up opportunities for small scale manufacture of parts like timing gears.

    Similar figures to what the local precision engineers gave me Bob.   I have several alloy cam gears, but no crank gears, these are the scarce commodity.   So now we have to wait and see if anyone wants them made.   If previous experience proves true, most people will want us to get them machined and hold in stock just in case they may want one some day.  Not on!

    What I had in mind for the cam gears was to have narrow and wide 14.5° versions made. 
    That way people could just swap the cam gears straight in and use them with their existing crank gear. 

    I guess it would also take the strain off the supply of 20° crank gears.

    Great idea Bob. In fact there is no need to get a narrow and wide version, as  the wide gear does fit in the early timing case if you use a thicker gasket, and the overhang of the gear is not going to cause any harm. What you will need to do is provide relief in the spokes  for clearance of the  engine plate bolts.   I  remove the lock washers from the bolts, and trim the heads to half thickness. which works, providing the  cam thrust washer is the correct .062 thickness.   Also  grind about .060 off the inner side of the spokes where they run against the bolts.     The factory kits came with special countersunk head bolts, and the originals had to be  removed and the  holes countersunk.

    Did I miss something? What year & engine are we talking about?

    What Bob is envisaging is getting new alloy cam gears to suit the earlier models 1934 to 1940.   These are 14-1/2 deg.pitch gears, whereas the later ones are 20 deg.   This would enable just the cam gear to be replaced, as it is quite a task to  change over the crank gear with the engine in  the frame.

    I need to change over the crank gear with engine in the frame for my 37T. Was planning to support the sump, remove the front engine support plate to get better access to the crank gear and make a puller to remove gear. Is this the way to do so? A new support plate gasket would be reqd. Was planning to put back a 1946 engine support plate. Thanks for replies & comments

    Have changed the crank gear before without too much trouble while in the car,just check that front plate I think you will find the support legs are different.

    All you need to do to the '37 plate is countersink the screw holes. I have made the change to all of my 3X5 engines.
