[Staowners] speedo speedo

[Mal Clark]

Kevin,I do wish you luck with your purchase of the Sunbeams,and speedo readings,your last problem,all I can say is welcome to,I think a inbuilt problem of our cars at  55/60 MPH of what is described by many and myself as Scuttle Shake,the Sunbeam list discussed this problem, a while back, and all sorts of ideas where suggested,all I can say is the Sunbeams I have owned they have all had to Shake at the speed you mentioned,it is a transverse scuttle shake (across the car) and transmitting through the seats etc,you can drive through it,at a higher speed, similar to out of balance wheels,but its not, I have never cured it or found the reason it occurs ,my have to live with it, until someone does cure it,I would be too concerned, good luck Mal Clark.

  Kevin, When I installed overdrives to my cars I took them to a speedo specialist here in Portland who have a rolling road and a gauge that measures the actual and indicated road speeds. They then assemble a geared ratio adaptor to even out the difference and install it in the speedo cable. Cost about $120. Seems a lot easier than trying to find a different driven gear. 
  Regarding the vibration,how's the wheel balance?? Often times when you can "drive through" a vibration it's a wheel balance or run out problem.You may check the wheels for run out as well as balance. What was the Sunbeam turnout at Bellevue?? Unfortunately  I wasn't able to make this of all years.                   Pete

    HI All. just an update on the 4 Sunbeams in Victoria B.C. debacle, the seller has returned my cheque after 4 weeks and I have in turn served him court documents to uphold his part of the deal and release the cars to me, so we shall see what happens I will keep you posted. 
    On another matter I just returned from the annual British field meet in Bellevue ( Seattle) WA ,it was the salute to Sunbeams this year and is only a three our drive, the car ran great but I (the car) has 2 problems, the speedo is out by .6 of a mile, using the mile pointers on the side of the road my speedo reads 1.6 miles for every mile traveled, I have a non stock o/d unit on my original trans so I suspect I need to change to a speedo gear with more teeth, anyone know if they swap out easily and how many teeth = .6 of a mile ??  Secondly at an indicated speed of 55-65 mph I have a driveline vibration / grumble that goes away at faster speeds or slower speeds and is not there on deceleration, trans??? or ?? 

                    Happy Beaming
                                           Kevin
