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 ?

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 ?

Thanks Andy...I'll shim it up to give just a hint of back-lash as per the manual

Just to close this one off:
The general consensus is that the oil seal should be fitted with the spring towards the inside
The problem with the mag rocking on its base was a simple one- there were only 2  locating studs; one of which was had be badly home made and was slightly too long- stopping that side of the mag from seating correctly. Made 3 new studs of the correct length..problem solved. "Jobsa guden"

Thanks Dean... There are 2 studs diametrically opposite on the base of the mag and 2 threaded holes on the other diagonal. With the studs seated in the recess in the crankcase it still doesn't feel secure- its "wobbly".. Should there be bolts in the threaded holes ?

OK... I reckon the seal was originally put in the wrong way round so I'm going with my instinct on this one. However I am concerned that the mag doesn't sit very well on the crankcase "plinth" and actually rocks.... This cant be right surely ? It will clamp down with the strap but....

any thought appreciated
