Morris Minor Owners Club

At long last I have taken delivery of my Traveller, "Ernie". So I'll be ducking my head in for lots of (dumb) questions and advice!

Right off the bat- It has 13" wheels, and they look kinda small.

-Were 14" standard?

-Is it possible to run 15" without clearance issues?

-Do 15" look too big?

Engine-wise, wondering what adjustments might need to be made for my high altitude (8000 ft above sea level). Engine seems to run well, but with the choke almost full out, even after warm.

That's it for now- Thanks in advance

Agreed

Were 14" standard?

Yes

Is it possible to run 15" without clearance issues?

Its the offset that will cause problems.

Right Dave what we need to know is the PCD of the wheels currently fitted (centre to centre of the studs) then you will know if it still has the original size or not 4" is the standard PCD.
As for Altitude re-tuning I really dont know what is suitable but I am sure someone will.

Kevin, thanks.
I'll double check tonight, but I think psd is 3.75...

3.75 is triumph PCD.
Austin/Morris stuff should be 4" - same as the MG Midget too.

Good to hear you got sorted.

I have nothing to add here, just to say Hi to "bloodyank" and to say I'm very jealous of you living in Colorado at 8000ft. Steamboat is a skiing resort isnt it?

You should be able to order 14" wheels from the usual parts suppliers who i believe can send to the USA again now.
Hoes is the Morris coping in the snow?- can you post some pics?

Sorry pCd.. what is that anyway... something center diameter..?

Pitch circle diameter - the radius of a line through the centre of the wheel studs
This browser's telling me I've spelled 'centre' incorrectly. No, I haven't

Thanks John-
Yes a ski resort here, and having a very good year snow-wise. (Snow is a good thing here). To give you an idea, our base, the amount of snow on the ground at the top of the ski mtn, is 92".
Total cumulative snowfall this season: 328"!!!
Took Ernie for a lap around the block yesterday... wheeee!!!! Not a great snow car. It's four or at least front wheel drive only on the roads only right now. In fact, the transporter who brought the car jackknifed his rig. No damage to my car or the $60,000 USD Lincoln Navigator that was also in his trailer, but bad damage to his truck and trailer. He can drive it o.k., which is good since he has to take the Lincoln to Oregon still. And he picked it up in Maine!!
I'll post some pics soon.

Maybe an other ignition,the famous 123ignition,will give you a better spark and it kind of tunes the spark as the engine is running,thanks to a micro comp.
And another needle in the carburettor.
But you should let you advise by an expert fot that I think.

Please tell us the PCD (again... distance between the 2 diagonally opposite studs) because if its 3.75" 14" wheels are next to impossible to find, however with some spacers MGF or MGTF wheels will fit (if you have them over there)

I'm even more jealous of you living in a Colorado ski resort now, 92" of snow indeed!

As for your trav running only with the choke out, I think that suggests an air leak rather than an altitude problem- check the inlet manifold gasket is not leaking and the same with the servo (if fitted).

Best bet of course to make up for altitude - is a supercharger! But assuming you don't want to do that at the moment then yes a richer needle will be needed in the carburettor. If you can take the needle out - it has the code stamped on the shank in v small letters. Post that up and we can find a richer version for you! If you drive with the choke out - you will wash all the oil off the bores and cause excessive wear. It needs a little bit more fuel - but choke out is a LOT more fuel! If the car indeed has 3.75 PCD (diameter not radius) - then it has probably been fitted with a disc brake conversion at the front - and as above - few cars have that standard although it is the size used for some Triumph cars - Spitfire and TR 7 I'm sure you will find 14" wheels in that size - that's what's on my TR 7!

(again... distance between the 2 diagonally opposite studs)

Not quite Matt its the measurement from centre to centre of the studs which I am sure is what you meant.

O.K.- I measured my PCD last night and it's definitely 3.75.

Bad news?

I was hoping to find some minilite-style wheels, and to go to 14"

It looks like you might be in luck Dave , that is a Triumph size and minilites are available with that PCD and 14" diameter.

Another useful link with loads of info with wheel sizes and types of what's available (old and new)

What you will have to be aware of is the clearance between the inside of the tyre and the upper trunnion, so it you can identify what the rims are from you will have a good starting point to make sure the offset is not to great to cause the tyre to rub on the upper trunnion.

How does one measure such a thing?

I found these as well:

And these;
http://www.gbcarparts.com/proddetail.as ... 18p4x95.25

These are the correct PCD - you may find the centre hole fouls on the hubs - in which case the holes would just need opening up slightly. You need to ask them for a dimension from the hub mount face to the edge of the wheel (basically the offset from the centre line) and see if there is enough clearance on the car allowing for tyre sidewall bulge. You msy need to fit spacers on the front hubs (rears won't be a problem) but you should minimise the use of spacers!

There is no problem in supplying 15" minilites with the correct offset and pcd. drop me a pm
