Re: Brake Unions

Could it be the smaller bore rear cylinders of the eight inch front brake cars are smaller diameter than the seven inch models? I've only worked on Series III Minors.

Re: Brake Unions

I've always had to part the half shaft to get the cylinder out for the past 45 plus years. It may be because the outer piston isn't fully home.

Re: Rubber or polyurethane bushes

Shouldn't they be shorter than the rubber bushings they replace? The rubber ones typically are longer than the metal pieces so that they are compressed in order to "clamp" into place. If the poly ones are too long such that excessive clamping pressure is generated, the necessary rotation may be at a...

Re: Rubber or polyurethane bushes

Since rubber bushings twist and poly bushings don't (the pin rotates), you really can't compare the rubber durometer reading with poly. A softer poly bushing allows more lateral movement if required, but is also a indication of the ability to support weight.

Re: 1954 American review of Minor

I inherited a Road & Track collection dating back to 54 and scoured through them and Minors were mention at various times with two road tests and always in a favorable tone.

Re: Export option

The timing of the 1962 left door lock is the same time that there were no "official" imports to the States. I think the attraction to these bigger cars over here is the upright seating position. The auto makers nor the buyers realize this. If there was a vehicle in which a person can enter and sit l...

Re: petrol tank feed pipe nipple

No significant amount of fuel could leak out because it's on the suction side, but the air leak would make the pump ineffective. If you can solder, it will be fine. If you are using a steel pipe, a good flux is needed. Pre-tinning is a good way to inspect it before the fitting goes on.

Re: Heater Fresh Air Intake

They are very common here in the States since 1959 had by far the highest import volume. It was introduced late in 58. There is enough pressure differential to create a low air flow. Even with the fan on I've never experienced any engine odors.

Re: 2 cyl A Series engine

After watching the five parts, I noticed that the block flares out a lot towards the sump. Obviously designed to mate with the FWD gearbox. BMC did a whole lot more than just shortening the block. What was the driving force to put the manifold on the other side? Was there no room for the normal cros...

Re: Original Half Shaft Failures

The half shaft from the splines to the flange are larger diameter than the root of the splines so therefore are not stressed as much. Surely the diameter of the root of the spline was designed with a safety margin to handle the torque, so there is no yielding of the outer surfaces. There is no perma...

Re: 2 cyl A Series engine

Did he mention why there wasn't a crankshaft and camshaft? He says that they aligned the camshaft lobes to be 180° apart. However, the crank was also made 180°. That won't work. There is no good arrangement for a 2 cylinder four stroke engine. It may look balance but the firing will only be every ot...

Re: Original Half Shaft Failures

The previous replacement were most likely used since I just grabbed what I had around, probably used, but I don’t recall if they had any wear marks and which side they were from. This current replacement was used and the wear indicates it was from the other side. The recent failure of the flange she...

Original Half Shaft Failures

I have a related posting in the mechanical section but I've decided to post one here for more visibility. For the last fifty years I've been the custodian of six active half shafts. Two cars are factory spec 948 Minors and one is a 1275 powered Minor van. One of the 948s has had three RH failures by...

Re: What is the cause of half shaft failures?

Ampwhu, I agree, I don't think half shaft are common in factory Minors or even factory tuned 1275s. Phil, I think you are missing the point. I have no extra power and it's the same location on the same car. For the most part the half shafts are not a wear item. If they were then as soon as they were...

What is the cause of half shaft failures?

I never bought into the transmission of torque causes the shafts to break and that the differential ratio has anything to do with it either since the torque on the shaft is the momentum of the car's weight only. Of course more HP translate to more torque. Some have stated that wheel bearings can be ...

Re: Rear brake cylinders

Although you can't hone the cylinder due to the slot for the lever, the bores can easily be cleaned with steel wool. I think the reason they were made with aluminum was to facilitate refurbishing. However, using steel pistons encouraging seizing. Yes, over the years, I rebuilt several cylinders with...
