hi all , can anyone tell me how the back wheel builds up on the speedo side of the spindle , is there a spacer that slides on the spindle between the speedo drive and frame with the clamp nut tightening it all up , or is it some other type of spacer , mine has a bodged up over sized nut that spaces the speedo drive to the frame , i think i have seen one on chases parts listing part number 90-6230 ? thanks ,smile .

Which model are you asking about? according to the Parts list for the D1 Rigid the parts in order out from the hub on the Speedo side are:

  1. Bearing (90-5525)
  2. Felt retaining washer (steel) (90-5538)
  3. Hub washer (felt) (90-5540)
  4. Felt retaining cup (90-5539)
  5. Hub bearing locknut (90-5546)
  6. Hub spindle locknut (90-5543)
  7. Speedometer drive (90-6024)
  8. Speedometer drive washer (2-1945)
  9. Hub spindle locknut (90-5543)
  10. Chain adjuster (90-6086) plus cap (90-6084) and nut (1-6032) 
  11. Hub spindle nut  (90-5542)

Note that the the 2 nuts either side of the Speedo drive (and its washer) are the same part number. The only time there is a spacer, is when the speedo is omitted.

Its subtly different on the D1 Plunger. The spindle and Speedo side spindle nut are one piece (and a larger diameter than on the D1 Rigid) and there is a spacer (90-6065) instead of an inner Hub spindle locknut.

If course, if you have anything other than a D1, all bets are off, as I only have the parts list for the D1, though I'm sure someone here will be able to help you.

 

cheers

The important thing is that the drive is securely clamped and does not turn, probably why someone has put some sort of spacer in as if the drive does turn it will rotate and destroy the cable and fixing etc. I know its not the same bike but this is the arrangement on my BSA A65, I somehow don't think these washers are original but they do the job and hold the drive firmly which is the main thing, in want of the correct spacer this is a good fix as I see it as this works well. These drive units can get dished over time and as I said the important thing is that it is clamped up well and does not turn.

Hi Lollypop.

     The D14 has a spacer between the wheel bearing and the speedo drive then after the speedo drive there is a nut that holds it all together. It is shown in the D14 manual in the tech tips section of this site. Refer to page F4 fig.4

It is important that when the nut after the speedo drive is tightened that the wheel can rotate freely without binding on the speedo case. If  the speedo case is binding on the wheel, then the spacer could be too short or the wheel bearings have not been fitted correctly.

Hope that helps.

             Mike.

hi mikef , just read your information , i dont understand what you mean , are you saying that between the speedow drive and the frame there is a threaded spacer that tightens onto the S/D , and then the wheel locknut fixes the wheel firm for chain tentioned ? mine has som sort of oversized locknut , i have tightened the wheel locknut onto this , would this crush the S/D ? can i buy the parts i need , say from chas/D,FLY , ? my machine is 1968 frame and engine . confused

Has anybody got any ideas about the dimensions (width) of the D3 rear hub speedo drive distance piece 90-6065 please?

There isn't one in mine but it doesn't look as though there is room for one.

Any advice would be appreciated.

Thanks

Barnz,

I`ve recently fitted new wheel bearings to my D3 plunger that I`m rebuilding.I`ve got all the rear hub paraphernalia secured in correct order on the spindle in a box,so will check later tonight for you after I`ve had my already late dinner....that`s if it isn`t missing like yours!

Some time later.....Couldn`t find the box,hopefully I`ll dig it out Weds

Hi Lollypop

mikef is correct

you keep saying S/D is fixed to frame IT IS NOT.. S/D case / body is fixed secure to wheel spindle via spacer onto inner bearing ring

forget how you found it as i think it was assembled wrong

start again i will try and guide you through assembly

with wheel NOT between swing arm and brake plate fitted,brake plate does not have to be secure but if is that's ok ie nut on spindle tight

on S/D side slide speed o drive distance ring it is not threaded over wheel spindle

then slide S/D case/body onto wheel spindle MAKE SURE TO LOCATE ON  WHEEL DRIVE RING MAYBE TURN S/D ROUND UNTIL IT LOCATES

then run lock nut onto wheel spindle up to S/D ,,DO NOT TIGHTEN

put wheel between swing arm

fit nut & bolt to secure brake plate from turning finger tight will do you can fit wheel spindle nut and tighten

on S/D side HOLD  S/D case/body so that exit for speed o drive cable looks to run along swing arm

hold S/D and tighten halfnut/ locknut .you may have to hold S/D body cable drive exit at 2 oclock so as you tighten nut S/D boby turns with tightening

wheel should spin without binding on S/D body check bearings if it does

speed o drive distance peice are for sale on Ebay not made in INDIA cheep

martello

fit chain ,chain adjusters fit S/D side wheel nut

Ok,I`ve found my complete rear spindle assy.

Going by this parts diagram...** Please log in to view **....we could be fooled into thinking it`s a dutty thick spacer,but the one I winkled out from  the inside face of the speedo drive box is just a thin-ish washer about 1/8" thick.I`ll clean the black grease off and measure up with the digital caliper for you if you want?Let me know.

I`d say mine is original,appears looked after,only stripped it to fit new bearings,everything else appears in good condition and in the right order.

You know how to dig`em out Piquet 🙂 Phil`s D1/3,pics 11&12 show the same washer(distance piece) as my D3.

BarnsleyB,I`d say that you`ve just got to make sure you`ve got enough meshing between the two tangs in the g-box and the hub so as not to mangle those tabs up,but so the body of the g-box isn`t fouling on the hub....I expect that`s stating the obvious though.I reckon that chimp has run off with your washer!

I can measure my washer if you haven`t already sorted the job.

Thank you sunny.

Thank you piquet, I had found that thread but it didn’t actually give any sizes.

Thank you blue heeler.

Sounds like mine is same as yours. I’ve messed around with It and in the end a pretty standard width washer fitted perfectly into the recess of the gearbox case and seems to have done the trick.

Thanks for all your help.

Yes, thanks blue.

Just got to put the new chain on now as the one fitted was the bigger type off the later bantams.

It's all ready to go then.

It runs really well and starts very easily.
