Busted one on a MG-TC back in the 60s but hadn't thought about that since. I'll definitely check that before pulling the engine/tranny. Hmmmm. If it was the halfshaft, wonder why the gear shift did what it did? Lessee now... I tried to downshift into third and it didn't want to go into third gear. Kinda like there was no gear there at all. Then suddenly it went in so I let the clutch out and something goes bang. I'm still coasting along so I thought, "Well, it's popped out of gear" so I moved the gear change lever... MORE
Is this leaded or unleaded, Jim?? I'm running tuned, hi-compression tyres so "suitable" is of extreme importance you see. :) Cap'n Bob Basic Frog "Robert E. Shlafer" 37175... MORE
2000psi ????? Hmmmmmm might be easier than drilling holes in the car to lighten everything! Could Happen! You could substitute Hydrogen for the Helium (which is even lighter) and then adjust the carbs to run on Hydrogen from the tires, and the further you drive, the lighter you get!!!!! Whadda concept!

Dave Fitted the exhaust manifold but it is hard up against the chassis rail, will show you. I am convinced the engine runs easier and purrs along smoother. I was going to put K&N air filters on, I wanted the one that spans the two carbs as I like the look of it but an owner I met at a show said they just made it noisier and no better so he reverted to the original ones but kept the sports manifold. You can have a look at my steering wheel problem and anyone got an oil cooler for... MORE
All comercial aircraft tryes have been nitrogen filled for years now, this is because it prevents the tyre burning on the inside. Also F1/Indycar and NASCAR tyres are also nitrogen filled, possibly for the same reason, but possibly not. Stewart "Ford Prefect" 37135... MORE
Oygen as a cause of rubber deterioration. that's a good line if you're selling nitrgen, but the truth is the two things which attack rubber are ozone and sunlight. Unless you're going to fill your tires with ozone or sunlight...we've all seen tires where the outside was hardened and full of cracks, but ever see that on the inside?...uh. "joe blxfstz" 37134...

Over this side of the pond it has been sold as a way to make the tyres last longer (no oxygen to attack the rubber from inside or something - sounds a bit more plausible than more mileage) A guy at work recently had some new tyres on his car and they put nitrogen in without asking, so when they tried to charge him for it, he told them to take it out and put air back in! David "David Jacobs" 37127... MORE
I found this in a short search: Nitrogen is also used in filling automotive tires due to its relatively flat line of thermal expansion. I also read that truckers (lorries) and the military use N2 for certain safety concerns and longevity. I wouldn't even consider it myself...but that's just me...H2, though, has a certain appeal... that would give a new meaning to the term "blow out"! "Jim" 37128... MORE
When I got my tires last month at the local big tire chain, they were peddling filling the tires with nitrogen as a way to increase gas mileage. I asked counter boy how that worked and he gave me some load of crap obviously written by the marketing genius who came up with the pitch. (Who's probably getting rich on it... so how smart am I?) I asked him since air is already about 80% nitrogen, why should it make that much difference. So he tried again. I just laughed at him. Now they're on the radio pitching it,... MORE
How about using Helium in the tyres? Might make the car 20 pounds lighter! That would save some gass mileage and increase 0-60 times also. Cheers, Bob in San Diego "Robert D. Gardner" 37137... MORE
It should be rather easy to find some study on the subject on Google. I think it is just a way for big companies to separate you from a few more dollars. When was the last time you had a tire damaged to the degree it had to be replaced from the inside by oxy? I ask you! It might get better gas mileage, but I bet it would not be more than a 01% gain. Adding one psi pressure would give you that much gain in mileage IMHO. A lot of the racers around here are using it,... MORE
Jim, Put in top gear, jack up one rear wheel and rotate back and forth by hand, how much free travel until resistance or a clunk? Look under and see if wheel moves very far before prop shaft starts to turn. Look at u joints to see if sloppy and hope that is where the extra play (read klunk) is coming from. Good luck Bob in San Diego "Robert D. Gardner" 37104... MORE
Well, the pinion size might be a compromise, since you can only have a whole number of teeth, so maybe they realised that they picked the wrong side of the compromise after the car had been in production a while and tyres with different rolling radius became available - I don't know, it's just a theory. I'll leave you with some numbers to think about - the difference between 3.7 and 3.9 diffs is about 5.4% and that between 22 and 21 teeth is 4.8% David "David Jacobs" 37093... MORE
Stewart, my 1977 edition of the parts list only shows the 22 tooth pinion. For a 3.7 diff, you would need one of the smaller pinions. To find out which one, you need the current wheel revs per mile figure (should be printed on the speedo face, as a four digit number by itself somewhere) From this and the old and new diff ratios, you can calculate the new wheel revs per mile figure and by proportion, the new pinion teeth. Or just go by trial and error and a stopwatch between motorway marker posts! David "David Jacobs" 37087... MORE
"stock 1275...3.73....smoke the tires" Yes it will. Most especially when we team the foregoing with the slightly lower 1st gear of the Datsun 5 speed "whilst" (I like this word........it's got a.............. well.......certain "flavor" so to speak) we enjoy a more serene 70mph cruise in 5th. With the Cooper S cam advanced 4 degrees for Metro inlet timing, I gotta be careful of this in the rain. In 2nd as well (in the lower range after the clutch is in, yet). And this with 70 Series 175 T/A's yet. Cap'n Bob "Quick" :{) "Robert E. Shlafer" 37074... MORE
A stock 1275 in good condition works very nicely with a 3.73. 3800 rpm (145-13 tires) = 70 mph, and it will smoke the tires in 1st gear. "joe blxfstz" 37071... MORE
Well actually Joe, you should know that everything is reversed in the Southern Hemisphere, so Down Under they are Bugeyes even with the wheel on the right. avagoodday Colin "Colin Dodds" 37069... MORE
Frogeye's have the steering wheel on the right side, Bugeye's have the steering wheel on the wrong side. With a few minor exceptions around the world. Cheers, Bob in San Diego "Robert D. Gardner" 37067... MORE
Okay, okay. Mk 1 Sprites with the steering wheel on the right are Frogeyes; steering on the left are Bugeyes. All MK 11 and later are Cheese Boxes. "joe blxfstz" 37061... MORE
Robert, You are going to be sorry you asked. For other listers, log off if this is too boring and it has NO LBC. Back in '72 or so, I was taking a camping trip around the United States with my then wife and two kids, age 9 & 10. We were driving my white Chevy California hippie van with side pipes and big tires in the rear. My wife was a fashion model and I had long hair and a beard. We stopped in Sheffield Texas for gas and I tried to buy some beer. The old crone... MORE
Pity about the non original wheels and spinners Stewart "Ford Prefect" 36962... MORE
Looks like another one for you Don. I'd be living in the shed with it if I bought another just now. But someone has already spent $$$ with the intention of restoration. eg the heater. But I'm most taken with the tread on the spare tyre. Mike "Mike Allen" 36919... MORE
Not to butt in here men...but.... with aircraft, the wheel and tire are marked as a "match" before the combo is installed on the aircraft. During use, if these marks move from this position, the combo is removed (tube moved in tire causing p ressure on valve stem..possible leak/failure) and the unit returned to the shop for "overhaul". Cap'n Bob '60 :{) "Robert E. Shlafer" 36911... MORE
Are you sure you are loosing pressure from the tube? Sometimes air can get trapped between the tube and the tire when mounted and slowly this "bubble" of air will leak out around the outside of the valve stem. How do you know it is leaking? Do you hear it? If you rub soap and water around the stem, do you get bubbles? Watch it and see if the air stops leaking at some point then add air to the tube and top it up and see if it still leaks. Bob in San Diego "Robert D. Gardner" 36913... MORE
Hi Ole, It's possible that the spoke ends and nipples in the wheel are not covered by a rubber band or some other protector. Setting still, it's not likely to wear into the tube, but with some driving, it could conceievably gradually wear into the tube and create a leak. Later, Paul A Portland OR "Paul Asgeirsson" 36909...
