More overdrive

I didn't have much time today but did have enough time to use a borrowed 5/16 UNF die to rethread the gear lever (thanks Bryce for the loan of the die).

With that done I was able to fit another overdrive gearknob, but this one is like ones used in competition with a toggle switch. It fits very nicely and feels nice and solid. Next up is wiring it in.

Not used to this

I have bought a non overdrive gearlever and today I thought I would clean it up and out of curiosity see how it looked against the overdrive one n the car.

Using a rag and turps the new old stock gearlever cleaned up a treat but I knew there were some parts I would need so I referred to my parts book.  Well everything I needed looked like should be in place on the one already fitted as they didn't seem different where they locate so I decided to partly dismantle things to take a look.

Here's the assembly and yes it looks like everything should be able to be switched over. Well, having come this far I might as well check it out a bit more eh?

So, I undid the bolt at 6 o'clock in ths photo and removed it. Then there's nuts at 3 and 9 o'clock but if I remove them that would still leave studs in place surely so how would the metal cover come off?

Well, only one way to find out so I undid them and out came the studs too. Then the cover lifts off with an "inverted saucer" that holds a spring below it. With those out of the way the gearlever came out and I could compare with the non overdrive gearlever.

They looked exactly the same at the gearbox end so rather than describe the blow by blow of reassembly it was in the tradition of the Haynes manual a reversal of what I had just done and here's the "new" non overdrive gearlever in place.
Before fully replacing all the trim I then took the car for a test run and all is well with gear selection and how great it is to have a proper "knob" to get hold of!

Meanwhile the car ran well for a good 12 miles or so but then started to bog down and struggle again. I think this could easily be more fuel problems as on a light throttle it pulled quite well so next weekend it will be checking the fuel pump again.

Confidence improving

Having identified a problem with debris blocking the fuel pump a number of friends recommended not replacing the plastic inline fuel filter I had used with another one of the same type.

This being on the basis that they can collapse where the fuel pipe clamps up.

So, I followed advice from Colin Wake and fitted a filter from a V6 Vauxhall Vectra which should certainly cope with the fuel flow on a 2 litre carb fed Triumph. Here it is in place on PMW.

Don't be alarmed by the fluid on the bulkhead as I had just spilled some water whilst topping up the washer bottle.
PMW fired up no problem afterwards and having checked for fuel leaks (non found) I took the car on the extended test circuit and all appears well. That's 40 miles now with just a small amount of hesitation at the top end of the rev range and the overdrive working too :-)

Back home I left the car running with the bonnet up so that I could look over the engine. I just found one leak and that wasn't anything to do with the fuel pipes or filter, it was a small weep from a heater pipe fixed by nipping up the clamp.

I think the next job will probably be fitting the non overdrive gearlever and nob so that I can do away with the annoying overdrive version.

Setting fire to PMW?

That is a rag stuck into the petrol filler neck but not with the inention of setting fire to the car even if it has been proving a pain.

No, this is part of a plan following various dicussions and thoughts on how to get the car to run like it wants to actually drive somewhere.

It will now start OK and run happily on the drive but out on the road it doesn't want to accelerate at all and hesitates.

Like fuel starvation but using my saying of 95% of all fuel issues are actually on the ignition side I have been working my way through different possible causes.

One being a non standard cam which meant that putting a strobe light on the car showed the timing to be miles out from the standard marks.

I followed through advice from Andy Pearce and basically after doing all this, establishing true top dead centre, marking this up and then going back 8 degrees btdc from this the car was running in pretty much exactly the same place timing wise as before with the same level of non performance.

Talking this through at the Cheshire and Staffs meeting I was advised it sounded very much like a fuel problem. Well I was reluctant to go down what I expected to be a blind alley but then my mate Andy Flexney suggested that yes it might be.

So today I got the car up on axle stands and checked the fuel pipe all the way through from the tank to the engine bay just to check that during the wild boar incident it hadn't been flattened anywhere. That proved OK so I then got my airline out, disconnected the fuel pipe at the engine bay end and blew air back through it to the tank. This is where the rag comes in as Andy had told me of a time he did this and fuel was ejected out of the filler neck all over a wall! Not this time having been forewarned but I could certainly hear air being blown through the fuel line and into the tank.

Next I checked out the inline filter which I lways like to have fitted just before the fuel pump. There was certainly signs of gunge in there as can be seen in the photo so I removed it all together.
Now this was not fitted by me but by my local garage. I just have a suspicion that it might have been fitted the wrong way round too as the clean part is on the "inlet" side which is not where it should be if it had been fitted the way the arrow shows the flow should be.  If it was fitted the wrong way round then could that also cause a restriction? Mind you, it was OK all round the 10CR until the wild boar incident.

Not being content with this though I took the glass bowl off the top of the fuel pump to get at it's own filter and found quite alot of muck in there too as can be seen in the next photo. In fact it looks like a tea leaf strainer and not a fuel pump :-(

Using the airline I cleaned all this out too and cleaned the inside of the glass bowl as well before reassembling.

So that was the fuel side worked through but whilst the car was up on axle stands I did a few other jobs too like topping up the reconditioned diff  with gear oil, tidied up a few connections and rotated the tyres.

Now would all of this improve the way the car drove? Would it drive?

Well initially I was just glad it started and then didn't pump fuel all over the engine bay. Then I ventured out on to the roads and it seemed a bit unhappy initially but then it was cold and hadn't run properly for a while so I took it all with a pinch of salt and checked everything over after a couple of miles. This in itself was much better than recently so Idecided to give it another couple of miles which turned into 10.

There's still some hesitation but in general the car is so much better. It pulled up a fair hill at 2500rpm in overdrive top for example and in the last couple of miles I deliberately left in 4th at 30mph and it was pretty much OK.

In fact  it was not bad at all, no sign of overheating either and I don't know if you noticed but I quoted overdrive too - yes my new knob (!) and wiring seems to have done the trick and overdrive is working too.

I know when to take a few wins out of a day's work so I put the car away, the tools away and spent the afternoon watching Derby County win again. That's the best blog update in many a long time.

The heat is on

Returning to the overheating problem.
A good friend of mine, Mike Charlton, loaned me temperature gun that looks rather like a phazer ffrom the original Star Trek.

Well, armed with Mike Charlton's phazer I went out this afternoon to check what the temperature actually was  when the electric fan came on and then what it was in comparison to what the car's temp gauge said.

Running the car up to temperaure at tick over plus a few revs (strategically placed calibrated brick on accelerator pedal) the electric fan cut in way too soon, even the temp gauge had only just crept up above cold!

So I adjusted that and then with Mike's phazer I was monitoring the temp at the waterpump, thermostat housing approaching 70 degrees or so when the fan came on again so I adjusted it up again.

A little while later the temperature gauge was in the middle, using Mike's phazer temps were now around 85 to 90 and a couple of minutes after that the fan cut in at 2/3 of the temp gauge.

When it cut out the temp gauge was back down just under 1/2 way, in fact where you would want it to be

I am taking it that the thermostat opened, the fan controller cut the fan in at around 100 -110 and it cut off again at around 85-90. The car happily ran at 1100rpm from then on at normal temp on the temp gauge.

I don't know why all this should have happened really other than it's blooming cold out there under the carport right now but until today it would have run at 3/4 temp with the fan on all the time I haven't actually changed anything that I can see that would now mean it runs at a normal temperature but the loan of MIke's temp gun does mean I can rule out a dodgy temp gauge as this seems to be accurate.

Here's a pic of the temp at the waterpump/thermostat housing a couple of minutes after I had switched the engine off.

Next I'll work on the poor running after tips from Mr Shedtune but that can be another week as it's too cold for me out there

Looking for a knob

I have seen this all too often. The overdrive gearknob switch won't stay in place which is a real pain and of course means no overdrive.
I have decided on a completely different alternative. It's possible to fit an alloy gearknob with a toggle switch which is much more robust and retains the ability to easily flick the overdrive on and off whilst holding the gearstick.

I am going with a different approach though which is cheaper and whilst not as hands on as the above option should be fine with how I want to use the 2000, more of a cruiser than a sporting car.

Here is an overdive switch for a TR2 which I have used in the past on a Vitesse I owned. That's not the position for it by the way but was a good place to put it whilst I worked.

 Although it would be good there I want to keep the power outlet for satnavs etc so I looked for options.

I then thought about using the location for the dimmr dwitch on the dashboard as the dashboard lights are rubbish anyway and there's no need to dim them!

Now started another saga where the car decided to fight me.

I pulled the dashboard out and removed the dimmer swicth which wasn't easy but when I fitted the overdrive pull switch it didn't really work well as a solution due to the gap around the switch. During removal of the dimmer swicth though the connectors became disconnected from the back of it so when I wanted to replace it I needed to use a spare I had.

I needed to get a little bit more clearance though and had to disconnect the tripmeter cable from the speedometer. When putting this back I actually found it was broken at the speedo end  but I thought this wouldn't be a problem as I had a spare on the original 2000 speedo. The cable had actually broken with the plastic connections falling inside the speedo so the job became a bigger one.

OK I thought, I'll swap in the whole 2000 speedo but then realised it wouldn't match as it has chrome rings whilst all the other gauges have black rings because they are Pi ones. Then I remembered a brand new TC one I had bought as  a Rimmer Bros clearance item a few years back. That had a black ring and the trip doesn't use a cable as it's a push button through the front of the gauge. I fitted this although it has a top speed of 120mph instead of 140mph but who's kidding anyone the car will ever see 140!.

With the dashboard back in I could return to fitting the overdrive pull switch.

I put it where I had in mind right from the start, where Triumph fitted a pull switch for a rear screen heater. This is fine as I can re-use the hole for a rear screen heater switch which I will need in the future.

So, a bit of drilling and fitting resulted in this.

A Triumph part in a correct location in the car.

Now what I need though is a gearknob for a non overdive 2000, maybe a complete gearlever too but that's for another day.

Working on it

Following advice from the Club Triumph forum I returned to PMW today.

I adjusted the Revotec fan controller down to minimum which meant that it would cut in at 70C. Here's what the temp gauge looked like then. Higher than would be expected which implies the gauge is over-reading.

Then I followed the instructions and turned the controller "up" until it went off. When it came back on the temp gauge looked like this.
That's where it stayed with the electric fan on all the time.

I checked to make sure the fan was blowing the correect way. It's mounted in front of the raadiator and I put some paper/card in front of it and it was nearly pulled into the fan so that's OK.

The temperature gauge stayed at this level all the time I went for a short run with the car but I didn't take it too far as it was struggling to get up a small rise in the road in second gear! The timing appears to be miles out using a timing gun  but when I tried to adjust it to something closer to where it should be the engine died.

Oh, and the overdrive switch on the gearknob came off again.

More things to ponder over.
