I have spent some time this afternoon trying to get the steering wheel boss to go onto the shaft. It seems to have been pinched in the middle so will only allow the splines to pass each other for about an inch; then it stops.

I have tried forcing the slot to open up a bit but so far no luck. I suppose I should send it back again before I make a mess of it.

Heat is probably your best option, wait until we have a cold day, put the boss in the oven, hopefully with the column cold and the boss hot you will then have enough clearance to fit.

What worries me about that is if the boss shrinks onto the shaft it would never come off again! I will also need to have some for and aft adjustment of the steering wheel.

Having spoken with the the very helpful Melvyn Rutter again today, I shall be returning the boss to him. The one I received was a new replacement and it seems like it is just 'Sods Law' that it is too tight for the shaft. This problem is something of a mystery to Melvyn who is naturally concerned that he may have a bad batch in his stock.!

Melvyn Rutter, of course, is a Morgan Main Agent. I would imagine - if my experience is typical - that his customers are well satisfied with the level of service on offer.

I can't help thinking...perhaps I should have bought a Morgan! Razz

One enduring memory I have is seeing the launch of the Morgan Plus 8 at the Earls Court Motor Show in 1968. I went with my Dad who also liked the brilliant orange "star of the show", but was much more interested in the new Jaguar XJ6....

I wish I still had the brochures...

It does strike me that whilst stainless steel offers an attractive finish, it's a far less ductile material than the original aluminium boss, so is going to require significantly more force to clamp tight. Is there a fundamental design flaw here? Or is the stainless boss made to be a tighter initial fit so there is less movement required to fit?

I am sorry if I have been misleading. The boss is made from a highly polished aluminium casting; not stainless steel. The concern that the supplier has is that he may have a problem with his stock. Either the bosses that they sell are too loose or too tight.

The problem I have is that the original (1949) boss will not fit my new steering wheel. The original wheel looks rubbish but may be all I can use.

I have packed up the boss and will be returning it to Melvyn Rutter. Hopefully he will have an engineering solution for the problem.

The only thought I had would be to drill and tap a "loose" boss and fit a grub screw ( or a chrome headed bolt) that would tighten onto a flat filed onto the splines.?

Today I noticed that the insulating material to the underside of the deck lid had come unstuck. I therefore removed the insulation before it caused a problem.

Having completed the brake servo system and re fitted the seat and rear deck, I gave the brakes a final bleed.

(I do this on my own with a very simple self bleed tube depositing fluid into a glass jar... and a Victorian dressing table mirror that allows me to see - from the driving seat - any bubbles being emitted.)

Once I was happy with the brakes, I ensured there was adequate brake fluid in the remote reservoir. I then fitted the wheels and lowered the car. I think of all the improvement to an original design that I have done, the remote reservoir is my favourite.

When I started the engine I noticed the supercharger belt adjuster - a jockey wheel - was loose and wobbly. With the jockey wheel removed, I realised that the design was poor and would never work as intended.

Unable to find a suitable distance piece, I wrapped some 3/8" ID washers in amalgamating tape and dropped them onto the the bolt. I then let it into the jockey wheel and tightened with a locking nut. With the jockey wheel re attached to it's arm, I adjusted the supercharger belt and once enough slack had been removed, I tightened the arm and started the engine.

The jockey wheel/ belt adjuster seems to now be working as it should.

I was able to drive the car in and out of the garage and test the brakes. They seem to work O.K.

What is not O.K. is the rev counter which has stopped working. It had previously shown erratic behaviour... but now has packed up completely. I presume the cable has broken but will not know for sure until I have investigated.

Nearly there Ray! You must be getting excited (and relieved!). Remember that we all want to see a video of the car being driven on the road by you.

You are either part of the problem or part of the solution

Hi Keith. A video would be a first for me.

I started it up again today and drove in and out of the garage and the brakes still work!

I took the cable off the tacho and disconnected it from the drive end. I think the cable is sound.
The problem seems to be with the drive. There is a small gearbox fitted to the end of the dynamater ..and it growls when I touch it.! However, the cable turns if I twist the gearbox input shaft so I can only assume it is the drive coupling inside the dynamater . The male end where it protrudes from the front of the gearbox looks very home made. There is a key on a square shaft. It was working O.K. before so what has happened ?


Here is a shot of the little gearbox...

I'm pretty sure repro gearbox's are available, I looked at one for a completely different project , but the ratio's were not correct.

If it is faulty you have nothing to loose by opening up, it can only have a couple of gears that you may be able to fix.

Hi Dave. The cable turns if I rotate the input shaft by hand. If connected up, with the engine running, the instrument end of the cable turns.. I have opened up the reduction gearbox and it all looks O.K. in there. The cable, it seems, cannot operate the dial.

If the instrument is faulty then I will be rather annoyed as I had it professionally restored (along with the other instruments) by John Marks (Vintage Restorations) at not inconsiderable cost.

Then again I remember reading years ago about what could happen if a small 'U' shaped washer is left off each end of the cable. It prevents the inner from retracting into the housing and so not engaging. I don't think my cable has these pieces...so that is something I can investigate. Wink

I looked at the ends of the cable and there is no provision for a retaining ring.

With the cable fully inserted into the gauge and the gear box disconnected from the drive, I rotated the input shaft by hand... and with the aid of a mirror on the seat, watched the dial for any signs of life. There was none.

The instruments fitted to these earlier T series Midgets are 'chronometric' as opposed to magnetic and are normally pretty reliable. The downside is that they have an incredibly involved - if not complicated - clock type mechanism.

I have an idea of how chronometric instruments should work but I am unfamiliar with the causes of their failure to do so. In other words; I don't know what is wrong so have little idea about how to fix it.

An interesting description is detailed here:

Having been off the road for some time it may be a bit of corrosion and a drop of oil or spray of WD40 or Lithium may cure your problem. My Morris 8 had this problem and broke the cable due to seizing up. Some lube into the speedo and freed it up and it has been OK for the last 30 years. (with a new cable - of course)
