Cam identified

Thanks to Paul Bodiam I think we have identified the cam as a Kent Sports R profile.

Application - Sports ' R '
Power Band - 2500-6500
Cam Lift(mm) - 6.62
Valve Lift(mm) - I 9.69 E 9.69
Duration - 295 Deg
Timing - 39/76 76/39
Full Lift - 108 Deg
VC (mm) - I 0.56 E 0.61
LTDC - I 2.18mm

Whatever all that means!

The TH2 isn't listed in the tuning books I have but then I don't know much about cams so wouldn't really know what's similar. I'll get measuring to make sure that's what it is but seems likely.

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...
