Model 50 help

Jak:

The ks return spring replacement is rather straight forward:

remove the ks lever,and clutch cable, then remove the outer cover and the spring is readily accessible. When you get the old spring out check to see that you have the complete item and that no pieces are floating around in the gears.

On fitting the oil pump there is a sealing washer pn E6283 that needs to be fitted to the feed bush.

And yes, the cylinder head can be easily removed from the engine while the engine is in the frame. The replacement of the valve guides I would leave to a specialist in order to get a proper fit.

Good luck. I would suggest getting the parts list and the workshop manual for your bike.

Hello Jak,

RGM motors have both the 1959 Norton parts book and the maintenance manual and instruction book and they aren't the photocopied versions offered by Bruce Main-Smith, though the latter won't be a shame to get oil stains on whilst working on your model 50.

I've a couple of problems with my 1959 model 50. It could probably do with a full rebuild but for the moment I want to get it back on the road ASAP as it is the best bike I own for riding in the current weather. Firstly the kickstart return spring has broken. Is this a simple job to replaceor does it involve a major strip down? Apart from the spring and presumably a gasket are there any other parts needed? I need to replace the oil pump and have just ordered a good secondhand one. Are there any seals or gaskets that should be replace before fitting this? Is it possible to remove the head easily whilst the engine is in the frame and are the valve guides awkward to replace? Lastly has anyone used Summerfield engineering lately (they used to make Manx replicas) are they still doing Nortons?

Thanks Jak

hello jak fit valve guids are easey even a woman like me can do it , First you need a valve spring lifter to remove the spings and then the valves Then place in oven at gas mark 10 or full on go have a cup of tea and a bacon butty then come back too the job in you need a peace of wood about 2inch thick by 6 inchs squier and a valve guide drift then get the head out of the oven you will need engineers leather gloves the cylinder head will be very hot bynow so be careful place on the bloc of wood upside down and insirt the drift and tap the valve guide out with a small hammer a copper one or nylon headed one the valve guide should drift out with ease ? wyle the cylder head it hot you drift in the new ones once the head is turned over ? hope this helps a ? anna j Dixon
