    TR4/4A Rear stud spins! How do I get it out?

    Greetings! I've searched and searched and read a whole slew of posts about the "threaded" wheel studs on the TR4. I'm restoring a 1962 TR4 that has obviously seen some pretty bad days, but is finally beginning to rise from the rust. One thing I have to do is replace all the wheel studs as almost...

    New Member Intro. and Maybe Something of Interest to You

    Hello All, I've lurked long enough and will now join your knowledgeable community. To smooth my entry and establish some "bona fides" as a Triumph nut I will provide a possible answer to an old TR4 competition question at the end of this post. But first too much about me and my cars. My...

    TR4/4A TR4 front and rear suspension

    i have an early TR4. i need to replace the front shocks and the rear lever shocks. it looks like the front shocks just unbolt? is it as easy as it looks? i'm assuming you don't have to tear into the front suspension to do this? on the rear, i've got panhard bars; they are welded in. i'm...

    TR4/4A TR4 Carburetors/Idling

    Have adjusted the carburetors SU-H6 as the two front spark plugs were running too rich. Flow meters show identical measurements. Gunsun Colortune shows blue/ red flame. Still the two front cylinders are fouling the spark plugs. If the mixture is set to more lean, it won't idle when driving...

    TR4/4A Which seat frame do I have?

    Hi Guys! I've stripped my passenger seat down and would really appreciate your knowledge on what frame I have. My TR4 was built 10/23/1962, but my seat covers (per Moss pictures) are from a 4a. Are my frames from a 4a? The front of the passenger side has a small 'dent' in the lower rail that...

    TR2/3/3A TR4 Air cleaners on TR3

    Would appreciate any clarification of what I have read on some of the threads about alternative paper air cleaners. Do the early TR4 paper cleaners fit the TR3 carbs AND clear the inner fenders? Were the TR4 cleaners a complete disposable assembly, or were the paper filters replaceable? I see...

    TR4/4A wheels

    with the slow disappearance of tires, especially high performance tires, for the TR4, I am looking at 16" wheels. I know you can put them on a TR6; does anyone have experience doing that on an early TR4?

    TR4/4A electric fan

    i have a 62 TR4, which was pretty modified by its two previous owners. i've kept up the tradition; it needed an engine rebuild so we upped it to 89 mm pistons. needles to say, it runs a bit hot. did not have a mechanical fan on it when i got it; it had a pretty strange big heavy metal motor...

    TR4/4A Velocity Channel Fantomworks TR4A

    Hello everyone, Jay here. My TR4A is on the Velocity Channel Fantomworks Season 3. "Jay wants a stunning TR4A" Needless to say they took some editing liberties. They give you the impression that Dan delivered it back to me in some sort of drivable condition. I received it from him with a...

    TR2/3/3A Oil Pump Grief

    Due to aggravating circumstances early in the rebuild my original pump was lost. I have heard the horror stories concerning the "County" or reproduction TR3/4 pumps and I guess there is only the one production source which all of the vendors use. One would think that one of the big outfits...

    TR4/4A Flywheel... Lightened or Stock, that is the question

    I have a 1963 TR4 that I am rebuilding the engine from the block up. I have a new Findanza aluminium flywheel. I am increasing the bore to 87mm, and installing a very mild cam, otherwise it is a stock engine. What are the pros and cons of the lighter flywheel?

    TR4/4A Intermittent vibration at 3000 RPM

    Good Morning, I've got a bit of a conundrum. I've got this irregular vibration which appears to be somewhere in the driveline on my 1964 TR4. The vibration only starts when you pass 3000 RPM under power and it’s irregular. I think I can feel the vibration most in the gear shift lever but I can...
