Re: NH chain alignment

Pete If you gearbox is a CP type the part number for the spacer is as you quoted (3112-33) listed as 1933-52. My '42 WNG has a CP box so the spacer should be the same. The details of the spacer (sourced from AOMCC gearbox spares) is shown below: SDC12898.JPG SDC12896.JPG showing distance from back o...

Re: clutch and mainshaft

As Paul says, very tight. Use a good fitting socket and a decent breaker bar (other than the six bolts use a smaller lever here or you will strip/snap them). All those nuts and the six clutch bolts can benefit from an application of threadlock. Make sure the threads of the shaft threads and nuts are...

Re: SAFER RUST REMOVER

Sorry if I've missed something, but why not drain the surplus via the filler orifice? you can even get a finger in to remove the last drops of excess. Regards Mick There is an even bigger lip on the underside of the filler neck so emptying that way is not really on. Doing it through the tap boss is...

Re: 1942 RN WNG restoration-Updated 09/07 Pannier Frames

Have now fabricated the pannier frames, a very enjoyable project. Total cost about £45. SDC12886.JPG SDC12888.JPG I pressed the beads into the bottom plate using my hydraulic press. The die was a shallow piece of half round bar welded to a metal plate and the former a slot cut in a length of wood re...

Re: valve springs too strong?

It should turn over pretty easy by turning the back wheel in fourth gear with the plug out. There is nothing odd about the Ariel valve train so if you have the cam timing correct (so you don't have a case of a slight clash between piston and a valve) and you have valve clearance on both valves at TD...

Re: valve springs too strong?

Brian,
My '39 VH does not take any significant pressure on the decomp lever to operate the exhaust valve spring, a firm push with just the thumb is sufficient. The WNG is the same. I suspect your springs are too strong, where did you source them / any identification details

Cheers
Alan

Re: SAFER RUST REMOVER

I have used Slosh in three tanks and have had no problems. Their website says it has been tested with 85% corn ethanol so it should cope fine even if/when we reach 15% in the UK (currently 5%). Slosh do a clear and a grey coloured sealer, use the grey type as it is much easier to make sure the seale...
