Polls and RSS Feeds - oh and some tinkering

Well Blogger is getting easier and easier to use, I've now added a poll function and an RSS feed - not sure why or what for, perhaps just because I can :-)

Today has been a good day, I've re plumbed the PI so that the low pressure spill from the metering unit returns to the low pressure fuel filter union and the higher pressure spill from the PRV is totally isolated from that circuit and returns direct to the tank. I was concerned that having this high pressure spill joined to the low pressure in a "T" and then routed into the tank could allow the metering unit to become pressurised again. A pressurised metering unit will at best run rich and at worst, as we found out, run full rich and cause unnecessary but spectacular flame splitting form the exhaust!

Still looks like a rats nest in there! Once I'm happy with the thing I'll tidy it up!

Running the car with the various spills disconnected showed me that although the pressure is not great there is significant fuel coming from the PRV, indicating a healthy pump. There's very little coming form the metering unit indicating a healthy metering unit - it's new so it should be!

I also replaced the passenger side weather strip on the door, what a shitty job! I may not do the drivers side one! I even have the right tool for the job but still it ain't easy!

I managed to trial fit my new K&Ns - hmmm, some fabricating needed here. They fit BUT the middle one is tight (acceptable) and the forward one fouls the throttle linkages (unacceptable!). There's shed loads of room there so I think I am going to see if I can find some thin wall Ali tubing with a 48mm outside diameter and fabricate some ram pipes to connect the filters to the throttle bodies but in a stand off way so they don't foul.


If I can get the right tubing it'll work and may well help - I won't be able to get bell mouths in there but the filters housings are rubber so maybe I could squeeze some in?





Tomorrow I'm going to see if I can fit up the new headlights with their fancy blue bulbs :-) I also need to go for a long test drive and see whether my plumbing has improved things! There's also the small matter of renewing the front wheel bearings and the steering coupling and and and....

More Lucas PI info - some pearls of wisdom here :-)

Over the years I've collected loads of info and books about the PI system, some better than others. I have always meant to scan and post up some of the more interesting stuff. I had my scanner working recently (but not on my spanking new Vista equipped PC - incompatible!) so I thought I'd scan a few things when I came across an old trio of A4 sheets held together with a rusty staple. They appear to be pages from a magazine article but from where I don't know. The last page has a few small adds on it but no clue as to where it first appeared. The opening paragraph suggests and owners club and the adverts are 1990 vintage - if you know where this came from please let me know and I'll give them the credit. Anyway, I scanned it and OCR'd it and here it is. I've been through it to correct the OCR errors but if anything doesn't make sense shout up and I'll check the original.

Worried about your trunnions? Relief is to hand!

Image
This is an bit of an infomercial for my mate Dave and his company Canley Classics. I know Dave well, I get most of my Triumph stuff from him. I sometimes work on the Canley Classics stand at shows, I own a Canley Classics T shirt and I have spent many hours driving Triumphs with him. Other Triumph parts suppliers are available, your mileage may vary and this may contain nuts. If you don't like what I say, ignore it :-) - It's a well know fact that the small chassis Triumphs have some design frailties. One of the more spectacular failures you can suffer stems from the front trunnions. When you get a failure here you can loose a front wheel - this isn't a good thing. Often incorrectly known as "trunnion failure" what actually happens is that the vertical link that sits in the trunnion snaps - it does this for a number of reasons, lack of maintenance, fatigue, corrosion, previous trauma, bad luck. Most often it's the nearside that goes, it's the side that

TR6 Clutch investigation (and interior replacement)

Image
Blimey, it's been a long time since I did anything serious in the garage. Having found myself with some time on my hands - I'm currently looking for paid work again - I decided it was high time I sorted out the TR6 interior. When I got the car it was the interior that let it down, a bit of a mix of old and repro trim, mostly past it's best, carpets stick directly to the floor and sagging seats. I did the seats immediately and then gathered the parts to do the rest - new carpets, underlay, a trim kit, H frame cover, clips and fastenings, glue, etc, etc. So it seemed like a "cheap" job as I had all of the big cost items. It was just time - and now I have that. So I stripped it all out and there it sat earlier this week, looking all empty and then I thought what a pig of a job it would be to have to take it all out again to fix the clutch! You see I've always had a tricky clutch in the car, not awful but occasionally when warm it gets quite "off/on"
