5 bolt hub

Post by r wheat »

Hi I have a rear wheel that resembles my 1941 matchless rear wheel but has a 7" hub and the sprocket is held by 5 bolts to the hub, where has the war bikes have 6 bolts and 6" brake, does any one know when the 5 bolt sprocket was first fitted thanks Richard

Using the archives and looking at the parts lists the drum changes were in 1948 when they went to a 6 hole 7 inch drum followed by 1950 when the 5 hole 7 inch drum/sprocket was used for the swinging arm Road 350s and 500s. The rigid machines retained the 6 hole 7 inch drum but used the 5 hole hub for both by 1951. Oh the rivets counted during this lockdown! Will we be seeing an advert for the drum?

Hi many thanks for the answer, the wheel came with matchless 1948 basket case 350 the spindle is a large 5/8 bolt with the threads shot, the wheel was good, bearings ok so I had it powder coated thinking that it actually belonged to the machine, I only realised something was wrong when I got a parts manual, so I will now be looking for a complete 6 bolt 7" rear wheel hub. yes at some point I well may be up for sale. thanks again cheers Richard
