Model 7 head steady

Hi Philip, I've had a 1954 swinging arm framed Model 7 for the last 15 years, it's never had a head steady so I assume one was never fitted. The bike rides well and doesn't vibrate plus no fixings vibrate loose so I haven't seen a reason to fit one. I'll be interested to see if anybody can confirm if one was originally fitted or not.

The Nomads have a similar frame to those of the swinging arm Model 7's. If there is a bracket on the top frame tube, that will take to bolts or studs, then that was where the head steady was bolted to. The head steady for the Nomads, was a triangular part, that bolted to the cylinder head.

Hello Philip

my 1955 parts list shows a steady stay part number D12/932, so it was there from 1949. There is no illustration of it though. I made a stay for my 1954, and will take a photo for you, It may take a day or two as we are snowbound at present, and its more than a two minute job to get the bike out from the back of the shed. Its 25 years since I made it, but I remember it was fairly straightforward.

Norvil suggest using part 067856 as a replacement for D12/932.  This is a standard Dominator Head Steady strut.. Several postings above suggest that the D12/932 item, although listed, was not a common feature on Model 7s. I agree.The earliest drawing of the Model 7 engine show the top stud for mounting the head steady but not the plate itself or where it is fixed to on the frame.

From our photo library-I will check the pix of H&J bikes

A "J"  bike pix shows the head steady attaching to the frame rail stud above the carburator

Hi Philip, Attached are a couple  of photos  for you. 

The same part fits a plunger model 7, swinging arm model 7 and also a rigid model 77 500 cc twin. 

If you want a template  send me a PM. 

In the Model 7 Parts Book the Oil Feed for the Rockers is a T-piece that sits vertically between the unions. I guess this must also have the Head Steady passing under the T.  Dave's engine looks to have a modified feed layout.
