How an old person takes the hardtop off on his own
RVWP's idea.

Thanks - ordered. JJC

Anyone got a part number handy for the replacement stop light switch? Think I used a BMW one but can’t find the bill and it’s gone duff. Thanks. JJC

On the General Forum there’s a post about mesh wind deflectors. Peter W says that wind tunnel tests on (I think) an MG showed a reduction in drag coefficient with the mesh present. Would be interesting to know if a mesh deflector stops the air flow over the boot lid reversing. Can we persuade a mesh owner to do the experiment? JJC

Alan. I think that saves me modifying my wool as that was my next step. That combined with the sideways flow at the edges pretty much says it all about exhaust positioning. JJC

For many years our 6 had a wheelbarrow exhaust system, it also suffered from fumes in the cab and consequently smelly clothes. At the last rebuild a few years ago I fitted a standard exhaust and no longer suffered from fumes. So I was curious about airflow. Made up a set of wool tell tales hanging from the boot. RVWP (of this parish) observed then we swapped over. The wool only goes up to horizontal possibly because it’s a bit heavy so unable to say anything about airflow back up over the boot which was what I was looking for. What I did notice was that at both sides the airflow goes out beyond the car sides. Right over where the standard exhaust comes out. Have a plan for modifying the kit to make it more sensitive so sometime might have another go. JJC

Bonnet catches as used before the Dzus type catches. Only for early car purists I guess! Oil filter attachment looks as though modified for a cooler, no idea where it came from. Last call for TR4 hub caps then they’re going to the tip. JJC

I’ve uncovered four pretty tatty hub caps and a passenger door which doesn’t look bad at all. PM me if interested JJC
-
I’ve put a post on the 2 forum about clearing stuff from my loft. Also just spotted 4 hub caps with bad chrome. Free to anyone who wants them. JJC
-
Odds and ends going spare as my TRing days are over (too old). Bomb starters, clutch covers, speedo drive end cap, Lockheed rear axle, rear w/cylinder (new), w/s lower seal, sump - bits like that. Really don't want them going on the tip. PM if interested. JJC
-
And if anyone wants a 4 exhaust manifold and down pipe send me a pm. Also free I don’t want to put it on the tip. JJC

Rob - thanks that’s a great help. JJ C

How many amps should a standard alternator deliver? Is there a way of checking performance other than turning the headlights on and looking at the ammeter?JJC

Be grateful if someone would pm me Paul Bishop ‘s (think I’ve remembered his name correctly) phone number. A friend is thinking about seats. Thanks, JJC

Roger that’s what I was hoping. Easiest to fix.

Another fault has appeared. Stuck in traffic or idling temperature indicates fine. Running at 3000 rpm or more the gauge goes right up. Knock it out of gear and the temperature drops quickly. Anyone experienced that? JJC
-
Thanks for the replies. I’ll trust to the original AC diaphragm which replaced the failed after market one but will look at a petrol tap because a failed diaphragm drains the petrol tank into the sump under gravity. JJC
-
Thanks for the replies. Sounds as though I can risk the original AC diaphragm to replace the failed after market one. Bearing in mind that a failed diaphragm allows the tank to drain petrol into the sump under gravity think I might investigate a petrol tap . JJC

This post also appears on the 4 forum. I’d be interested to know how many of us have been running pumps with the original AC diaphragm with no problems due to unleaded. Thanks. JJC
-
I put this on the general forum but didn’t get answers. So this is a repeat, sorry about that. I’d like to know if many of us have been running original pumps with unleaded with no problems with the original AC diaphragm. Many thanks. JJC
I’ll post it on the side screen forum as well.

I’ve just had a failure of a recently rebuilt pump. Actually more than just a failure a real pain. Think where the petrol goes when the new diaphragm fails. And it doesn’t stop.
As I had a box of old pumps in various states of disrepair I found an original AC diaphragm. Encouragingly labelled “genuine”. Fitted it and it doesn’t leak, yet. My question is how many out there still have original pumps which have suffered modern petrol? Will my AC diaphragm survive unleaded? JJC

I keep saying this. I’ve got a 3 synchro box free o anyone who can collect it from deepest Dorset. It Must be good for parts. Eventually I’ll put it on eBay or the tip. JJC

I have a 3 synchro box looking for a home (free).JJC

Have ordered the needle version from Burlens. The Grose is going back for a refund to the other supplier JJC
Time to part with the 4
in General TR Technical
Posted
Sadly this year the 4 has been hardly used. A couple of trips to Sainsbury’s and that’s it. Not good for a TR. So it’s time it went to a new home. Completely nut and bolt rebuilt using a body from TRBitz a few years ago. It’s a Surrey (soft top) car, yes in Red. If you’re interested send me a pm. JJC
