Douglas t35 stationary generator

[Willo]

Can any one please advise me if the crank shaft on the stationery generators is the same as a t35 mk4 motorcycle crank shaft,as I think I may be able to get a wrecked generator, and are clutch plates still available for a t35 mk4 motorcycle
Many thanks in advance for your replies  willo

Willo,

itīs nearly the same crankshaft (only on drive side is a small difference) and it is possible to use it.

You can get further informations in John Holmes article about overhaul T35 bikes (you can download it free).

There are 2 main differences between the generator engine crankshaft and the motorcycle crankshaft. Firstly, the shaft on the drive end of the generator crank doesn't have a register to fit an oil thrower, and secondly, the timing end is a little shorter as it only had one timing gear that drove both the cams and the magneto/governor assembly. To fit the generator crank, you will have to machine down the timing gear retaining nut to a stepped nut to retain the 2 gears. You will also have to play around with the key, as it is a square key on the generator and a woodruff key on the motorcycle. Also, be careful - the generator timing gear looks the same as the camshaft drive gear of the motorcycle, but the keyway is half a tooth out.

  Many thanks Eddie that was not what I wanted to hear,
 but at least I can use the barrels , pistons and connecting rods.
I believe the barrel fins need a bit of modifying .

Willo,
         I have just stated the differences that you will encounter when transplanting a generator crank into a motorcycle engine - they are not great problems, but it helps to be forewarned of the little snags that may occur. Quite a few owners have already accomplished this crank swap.
      With regard to using the barrels - they can only be used as a direct replacement for the early T35 barrels - they are not the same as those fitted to the Mk3 - 5 machines.

  Regards,
                Eddie.

Thanks Eddie once again you have burst my bubble, mine is a mk 4
what I was trying to do is build up spare parts .  You know if you have spares around
then they are seldom used, like a insurance policy.
are clutch spares still available and who may stock them.
     Thank You  willo

Look out - here goes another bubble!
  As far as I am aware, clutch spares are getting hard to come by. Release bearings are the biggest problem as they are not easy to reproduce.
  When I was involved with the LDMCC spares scheme, we had all the parts made for the friction plates - you will need to enquire as to what stock is still available. Even if they cannot help at this time, all enquiries will be noted with a view to assessing the viability of getting fresh stock made in the future.

  Regards,
                Eddie.

 Thanks Eddie will join the club and find out   Thanks willo

Hi Eddie out of curiosity what item in the parts book is the release bearing you mention as difficult to reproduce.

Regards. Colin

Plate 14, Items 7 & 16.   Item 7 was originally made from a forging and is not an easy item to fabricate, bearing in mind it also has to be case hardened on the bearing track and ramps.

Thank you Eddie
