Have you tried the new Drafts feature yet? I just lost a long message today and learned my lesson. It is a good idea to save a draft of any long post you are writing. You can then just keep writing and keep saving a draft, knowing you have a backup if there is a glitch. The draft is automatically deleted when you post the message.

The handbook says grease and give a period trade name, but it seems to have been a semi-fluid or self-leveling grease. Wheel bearing grease would get pushed permanently aside and not work its way into the sleeve gear bush.

Which begs the question - did these boxes have oil or grease in them ??
Being quicker to ask here than locate the handbook...

Yes, that is the level plug.

The gearbox shown is an early type, Later ones did not have a breather tube. There should be a port at the top of the case, to the left of the shift lever trunnion for the grease fitting.

General Douglas Discussion / EW Gearbox
Last post by Red - Yesterday at 17:25
It might seem a daft question but I assume the lower plug on the side of the EW gearbox is the level plug. The attached picture from the manual shows the upper plug with a tube which is not fitted on my bike - is this tube just a breather. I assume this upper plug is the filler plug but I can't remove it as after a couple of turns the spiggot jams up against the frame.
What am I doing wrong? Thanks

Thanks Doug, that is very helpful, especially seeing the amount of offset after the slight bend at the spline end.
I think that the peg on mine is more or less at a right angle to the lever - so your 'heavy foot ' theory is probably correct.

General Douglas Discussion / Re: Endeavour kickstart bent
Last post by Doug - 12 Jun 2024 at 18:43
George,

Took a little time to find the little devil.

There seems to be a slight kink as indicated by the arrow (1st image). However, the peg is bent slightly ground-ward so I cannot rule up this slight kink is not also a by product of a heavy boot and a long kick start pedal.

Looking from the edge (2nd image) it initially seems there is just the one offset joggle ad the remainder lies on a common plane.

But... stood up on end (3rd image) the offset does not seem to be parallel, but at a slight angle. At the bend it is 11/16 of an inch from the back face of the hub.

Shimmed up with the hub flat on the table (4th image) near as I can get it, and the lever arm does seem to be on an incline, as noted by the dimensions. This would be in the direction it would twist from 'heavy foot', so I am inclined to think it is not design intent. I think it is intended to be square to the transmission/chassis.

Give me a few days to knock up a drawing. This will if nothing else be insurance against misplacing the kick start lever again. Meanwhile the attached photos might get you started on a plan of how to correct yours.

Hi,

As it says above, I have for sale a centre stand for a Dragonfly with the correct mounting bolts/studs and springs. It's a bit twisted, as they all seem to be, but it could be an ideal candidate for straightening, reinforcing, and then swapping on your bike, as I originally planned to do. 

I'm looking for £35 posted to mainland UK.

Thanks

The Plus engine has originally a 30x62x16mm Ballrace  + a shorter bronze bush at the timing side.
I prefer a 30x62x16 single row cylindrical roller bearing  with location in one direction (like SKF NJ206 ECP) instead of the ball bearing, because the crankshaft gets the possibility to move in the bearing when getting warmed up.

Doug, your one certainly looks better than mine!

I'm happy to help you but have not got as far as the engine yet - it turns with some compression so my plan is to check the timing then see what happens....

My bike, possibly the earliest production Endeavour, had been somewhat kicked about and modified over the years.  I am trying to get it back more or less to how it was when first built but not as a concours example. Among other thing I have had the tank renovated, found the right instrumentation, completely rewired it, cast new alloy silencers, renewed the handlebars and put on inverted levers, made up a front brake rod, fettled up a crash bar and rear hub caps, renewed the rubber drive donut and made up a n/s toolbox.  I'd like to have the original Douglas type twist grip throttle - if anyone has any bright ideas on this?

Slowly getting there!

Regards, George
