Electrical Issue

Sat, 15 Aug 2026 18:43:06 +0000

New loom throughout fitted in April before Drive It Day. Since then over 800 miles of trouble free driving including journeys over 200mls and local short ones. Passed MoT test last Wednesday with no issues.

Today, first short run of 4 mls there and back OK. one hour later the same journey ignition light slow to go out. Slowing for junctions Light appeared more and more. Stopping at destination and turning to return home, Ignition permanently on for return 2 ml journey.

Tried new Dynamo with no result and tried two different Control Boxes in place of original but have now run out of ideas for a fix.

Any suggestions that might get me back on the road would be greatly appreciated. Had the car for over 30 years and rebuilt it from ground up, but this has me baffled.

Hoping you can help

TR4 1964: seats and carpets overhaul question

Thu, 13 Aug 2026 15:38:07 +0000

With a planned renewal of front seats (everything stripped, down to slight sandblasting of seat frames) at this year's end, I get the choice between nylon carpeting or all wool carpets.

Prcie difference: €500 approx.

What is your preference?

Did any early 4s have webbing instead of the rubber diaframs ?

Steering column clamps

Thu, 06 Aug 2026 19:41:04 +0000

I need to remove the lowest steering column clamp on my 4A and deepen the slot to get a bit more clamping force, but is there anything better I could replace it with?

Surrey window seal

Wed, 12 Aug 2026 11:59:30 +0000

It is recommended to use the "Moss" Surrey glass seal

Request to Moss shows that as they are now all one company with Rimmer : any request for the seal would be sent out from Lincoln from Rimmer

There are clearly different manufacturers

Any ideas?

Has anyone added hazard flashers to a 4A?

Sat, 25 May 2024 12:49:16 +0000

Folks, a project that’s been on my “safety” list is to add hazard flashers to my 4A. Originally I was going to get a kit from Revington. It was about £60 for the kit (no VAT) which seemed reasonable, but when I saw the cost for shipping I damn near fell over!

So……… I decided to try wiring something myself. To quote a certain farmer, “How hard can it be?”

I did a search here, but couldn’t find anything specific to the 4A. My plan was to look at a TR250 hazard wiring config, and try to adapt it to the 4A. But before I start down that road, has anyone done this mod, or have suggestions on what path to take?

Oh, and to remind everyone, I’m electrically illiterate when it comes to things like diodes, capacitors, et al so please bear with me.

Too many bolts

Sat, 08 Aug 2026 16:22:12 +0000

Dear all

I am reassembling my TR4 engine etc (it's almost done). However I (little bit messy) have two bolts too many. They are 5/8 UNC x 1 7/8".

Please consider attached photos. Can anyone tell me where they go?

Many thanks for your help.

What alternator ( again)!

Tue, 23 Jun 2026 15:37:44 +0000

The water pump on my TR4 is making a horrid noise so I’m going take it off and send it to E P services in Wolverhampton for a refurb. I’m going to take the opportunity to put on a narrow fan belt and replace the original generator with an alternator. So this post is seeking to update the advice on this perennial discussed job. My car is fitted with LED headlights which considerably reduce the power requirements, but I am planning electrically assisted power steering.
Following a trawl of previous forum discussion I’m thinking something like a 50 amp Nippon Denso unit would suit. Before I start the job, here are my issues.
What is the part number for the appropriate unit, and where should I get it?
Does any one supply the oft recommended heat shield to stop the exhaust cooking the new unit?
Can I get an off the shelf fitting kit with the appropriate unit spacers and bolts to line the new unit up properly, and provide the pulleys for the new narrow belt.
Any advice gratefully received

TR4 deep dish leaf springs

Sat, 08 Aug 2026 12:20:00 +0000

Hi guys I have a TR4 that has been fitted with some leaf springs that from the chassis number are incorrect and the car should be fitted with deep dish springs and the spacers. John kindly supplied me with some spacers but they are not handed like the WSM suggests they should be. The web tells me that these are the type fitted to USA rigid axle 4a and TR4 spacers would have the damper fixing gusset offset. Will these be ok for the TR4 or was something else different on rigid axle 4a? Looking for right first time approach

Kind regards Richard

Hole in Bellhousing.

Fri, 07 Aug 2026 15:35:18 +0000

Just been having a look at a 4a I am considering buying. I got the car up on a lift for a good look around. Now I am aware this was done and why, however it was a surprise to find a not very neat hole in the bellhousing obviously created by multiple drill holes. Considering it had been left open the clutch cover looked like new. Not an encouraging find.

Very early TR4 door check straps

Wed, 05 Aug 2026 21:14:10 +0000

Gentlemen,

My car did not come with the door restraints, and according to Moss they are no longer available. So this raises a couple of questions:

1. Does anyone here have a couple of complete units that they will sell to me.

2. If I have to go down the route of fitting the later version, how easy are the to fit. From the images on the Moss site they look completely different.

Thanks

Graham

TR4 bonnet to wing profile

Sat, 01 Aug 2026 17:02:36 +0000

15 months into the bodywork phase of my TR4 rebuild...

Looking through the archive, the topic of adjusting the gap between the bonnet and front wings is a regular one. My problem is slightly different, and I can't see it in the archive...

See photo, the bonnet and wing have a different profile at the front, which results in this ugly vertical gap. Everything else is straight and aligned, bonnet to bulkhead gap is perfect, bonnet to wing gap is perfect. The bonnet and wing profiles match pretty much perfectly all the way along except for this front area. Hinges are not installed yet, I'm just positioning the bonnet to check overall gaps and alignment.

Presumably I'm not the first to come across this.

Any thoughts on how to rectify would be welcome! Can the bonnet profile be reshaped, for example?

TR 4 Electrics

Fri, 31 Jul 2026 06:12:22 +0000

Posted by mods, on behalf of a new member, John.

I am new to the TR4 and classic car world with experience in classic bikes. My new 1961 TR4 has an electrics issue. No front or rear lights, no Indictators. The previous owner rewired it

I have traced wires done limited checks with a multi meter. I suspect I’m looking for a single broken or disconnected cable

Any suggestions on where to start. It’s a 4 fuse Lucas board. I can get power both sides of the fuse on the top 3 fuses. Nothing on the bottom. An expanded wiring diagram came with the car ( same one as the Haynes manual) but I can’t make head nor tail if it

Any suggestions would be appreciated

Thanks

Distributor vacum pipe

Sun, 02 Aug 2026 11:32:58 +0000

I’m recommissioning a 1962 TR4 and the vacum pipe was missing. The manifold end had a screw to blank it off and at the distributor end the pipe was cut off a crimped.
mom trying to fit a new copper pipe but the thread at the manifold end is slightly damaged maybe by the screw they used being slightly larger than the hole. Anyway the new brass connector screws all the way and holds, but when I try again with the pipe and olive in place there isn’t enough thread for the connector to bite and lock the olive in place.
I had wondered why the pipe wasn’t fitted, now I think I know.
any ideas. It think there is an adapter available which screws all the way into the manifold and then the pipe screws into the adapter?

help.

TR 4 clutch rattle

Sat, 01 Aug 2026 14:48:54 +0000

Over the winter all the drive train and engine has been off and rebuilt. Finally got everything together but when I use the clutch there is a metallic rattle. It is not there when in neutral or when fully in gear just when clutch is being used. Pretty much every time. Just taken gearbox out again assuming must be release bearing but nothing obvious. New bronze bearing sleeve and release bearing - rechecked they match the old one. The fork is double bolted and the tips look fine (gearbox was by Pete Cox). I can get a tiny bit of play on the fork but nothing much.

Noise really seemed to coming from bell housing. Stumped - anybody recognise the rattle in this video?

TR4 Dashtop

Tue, 28 Jul 2026 15:23:22 +0000

Gentlemen,

I have been speaking to the TR Shop about a new dash top for my rebuild. The gentleman that I spoke to said that the grain was different to the original ones. He also said that all the other TR spares sellers are now selling the same type of dash top. Has anyone bought the new type recently and their views on the grain pattern please. Or would I be better looking for a good second hand one?

Thanks

Graham
