Re: Brake Plate - Extra Hole?

Paul, I think the the extra hole is for the brake cable lug from the later 4467-53 plate - the ones that had the notorious "downward pointing" brake arms that caused wheel lock-ups. If any of your plates are surplus to requirements please let me know since I still need one for my 52 VH bas...

Re: Sq4 Timing sprockets

The camshaft might be culprit. As the follower goes over the cam peak it is pushed down the "off" ramp by the valve spring pressure and turns the camshaft ahead of the drive chain. The effect is less pronounced when the engine is running at speed but I suspect it is why the snubber was add...

Re: Lodge plug

They are generally considered to be of no practical advantage...

They are however easier to clean since the central electrode/insulator unscrews from the body.

Re: Burman gear box

21.8 mm is right for the diameter and 270 mm is about right for a SQ4 mainshaft length so it looks like you have been sent the wrong shaft from Drags.

Re: Burman gear box

William, Your original number GB3956 was from a 1956 NH350 - presumably someone overstamped it when they converted it for SQ4 use. Burman GB mainshaft FWHa.jpg The different mainshafts can be identified from the length between the 3rd gear splines and the clutch-centre splines. The photo above shows...

Re: CP mid cover

Wade, Sorry I can't help with a recommendation for someone to do a rebuild for you - I do my own gearboxes. Personally I wouldn't weld the broken top adjuster lug with the internals inside since the case will get quite hot in the welding process. Also, looking at the pictures in the advert, someone ...

Re: CP mid cover

Wade,

The picture of the 1946 box is not one of mine but one I happened across on Ebay. It is still a current Ebay listing (#323991665609) but appears to have damage to the top lug. I also suspect that the shipping to Canada would be prohibitively expensive for a complete gearbox.

Re: CP mid cover

Wade, I think the number on your 1946 CP box should be stamped on the main casing not the mid cover (as per first picture). 1946 CP Gearbox.jpg Later CP boxes were stamped on the middle cover as per my 1949 NH (picture 2) 1949 CP Gearbox.jpg The numbering in the first picture is for October 1946 i.e...
