I am adding some detail to the wheel hubs of my late Tiger and would like to know if these hubs were machined or cast or maybe both. Also does anyone know what the 2 small bolts and lockplate are for on the wheel hubs ?
Thanks
Steve

No answers on that one so i guess it will have to remain a mystery.

i think david grey knows the full detail on these wheels ,he did mention the trouble he went to at the open day,i hope this info is of use

Hi Steve,

I´ve looked through my books but never seen a cut-away drawing of the Tiger I steel wheels including the hubs to explain the function of these bolts i.e. the larger and the two small ones.

I wonder If Saumur took any photos when they overhauled their Tiger but I`ve never seen any. I think these hubs were cast and then machined. Here´s a photo of the Saumur Tiger;




I´m planning to build Armortek´s Tiger I as well and I liked your mod´s on the Tiger I wheels, very much appreciated, thanks for posting them.

Hi all

I like Steve's mod of the late tiger wheel hubs. It would have been expensive to mass produce, but it is an excellent engineering solution. On the King Tiger the hub covers are threaded and the caps screw in. To remove the wheels the hub caps are unscrewed, and the end cap on the axle is removed. We have stuck with the 14 hole layout to keep the wheels interchangeable with the late tiger ones, and to make the unevenly spaced bolts more obvious. As Steve says the space is there to drill the fifteenth one if you want.

I believe that on the original machine the the hub consisted of three taper edge segments secured by the larger bolts and provided with a smaller bolt for extraction. The principal is the same as the taper lock bush that we use on the sprockets.

Per,
Nice shot of the wheel hub, I have still got to get the center bolts machined to the correct thickness and put grease nipples on them before they are fitted. looking at the photo the hub does seem to have a bit of a cast texture so i think a light coat of Mr surfacer may be applied.
Mark,
Thanks for the kind comment, I was pleased with the solution myself .

Mark, I don´t know if I misunderstood Steve´s question but I was talking about the hub cap details and their reasons for being there. I´ve never seen drawings explaining these particular bolts.

Yes, the three rings around the hub base work like your sprocket lock bush with the difference that on some of the segments there are extensions that fit in two grooves on the hub which helps with positioning the wheels sideways. Here´s one segment (without extension) found in Hungary;

Per,
Just to clear up, My question was about the 2 bolts on the hub cap next to the large center bolt with the grease nipple in it. Looking at your photo it would appear that the center bolt is part of the hub end which may unscrew from the hub cap, if this was the case the smaller bolts may be lock bolts ?

Hi Mark .. That was the answer I was after . another great improvement on this amazing kit . Dale

Per,
Excellent detail photographs!

Steve,
That was my guess. Looking at Per's photo it almost looks like those two smaller bolts(and locking tab) are holding on the center disc? maybe?

Great stuff!
