Thanks for that Julian- it seems that the stainless pipes for sale simply specify either over or under gearbox routing with a generic B group listing but clearly as your explanation suggests they only actually apply to the swinging arm model

thanks

Singles / Oil feed/return pipes
« on: 07 January, 2018, 09:39:00 »
Hi guys
I would like to fit some shiny new armoured oil pipes to my B31 plunger; but all those offered for sale have a 90degree elbow union on one end; the fittings both into the crankcase and from the oil tank are obviously straight...  am I missing something ?

Singles / B31 front hub rebuild
« on: 22 December, 2017, 17:43:39 »
Hi Guys

I'm rebuilding the front hub on my 1955 B31 plunger after having the wheel rebuilt and after putting it together as per the service sheet it just doent "feel right"
I would have thought that the outer shell of near-side bearing should be flush with the lip inside the hub and therefore recessed into the hub by about 1/4"; but when put together the edge of the bearing is just about flush with the edge of the hub- see pic. The bearing is correctly positioned on the spindle- ie flush with the retaining lip and the bearing on the other side appears to be in the correct place.  Its so long ago that I stripped it down I cant remember what the original looked like;
There are 2 washers- a thick one with a cut-out (why I dont know) and a shim- I'm assuming the thick one goes on the inside of the off-side bearing and the shim on the ouside of the near-side bearing- the diagram on the service sheet isnt very clear, but in any case the dust cover wont fit

Anybody throw any light on this ?

According to my handbook for the D14; " Use self mixing 2 stroke oil (eg Castrol 2 stroke) at 24:1; or you can use non self mixing (eg SAE 40) at a ration of 32:1"
Do you suppose that the higher compression D14 needs a different mix ? I would have thought that as the engine is essentially the same the same mix would apply to all...but of course I could be wrong.

Hi

Operating the gear change lever allows the pawl to engage on one side with the ratchet but it wont move either up or down a "slot"  there doesnt appear to be enough free movement

Hi

Thanks but I've seen that and as far as I'm aware I've put it together as per the instructions.. but once place in the box the pawls are nowhere near the ratchet...so where am I going wrong ?

Singles / gear selector problem
« on: 06 November, 2017, 12:30:09 »
B31; 1955; M series type gearbox

Help !... this is doing my crust in !!!  I've assembled the gear selector unit as per the service sheet but once the springs are on they pull the pawls away from the ratchet plate. When I put the unit into the box I have to lever the top pawl carrier past the stops on the gearbox
I cant see there is another way of putting it together...believe me I've tried !... so what am I missing ????

Hi

Its a 1955 plunger model; the gearbox looks to be a "m" series unit as it has no cam plate and has selector forks;

In the process of putting back together my B31 (plunger) gearbox- according to the bible it is imperative that the dot on the selector quadrant is lined up with the dot on the casing...slight problem...got a dot on the quadrant but there is nothing on the casing.... any ideas ?
