Hmm - snapped the crank!

Well that was fun - having stripped out the gearbox and flywheel I couldn't see any issues with bolts etc - there was play though. I then reattached teh flywheel and started it up - wow, what a noise! Turned that off quickly!!
So, it appears that the crank is indeed broken, it feels like it's at the end - you can wiggle it around.

Some stuff I want to do whilst the car's off the road includes
  • fitting valve seats to the head
  • changing the push rods for 2.5 ones
  • changing the rocker pedestals for MkII ones
  • maybe renewing the rocker shaft
  • repairing the manifold and collector
  • re-wrapping the manifold properly - undecided on this, have heard that it's not a good idea on mild steel manifolds - this is a Gareth Thomas/Mike the Pipe example
  • change the exhaust for a single pipe system (anyone want a twin system? Make me an offer before I eBay it)

Engine choices?

  • Pull the engine, salvage what I can and replace the crank (I have spare, needs regrinding), replace bearings etc and put it all back together in the same block - that's assuming it's all reuseable which it may not be!
  • Build up my spare 2.5 engine and drop that in - this is just a standard 2.5, not decked. I could pull the cam from my present engine and reuse that though.
  • Build up with a 2 litre crank and head (I think I have a head!) for a revvy engine
  • Buy a second hand lump and throw it in
  • Buy a car with a nice engine and whip that out

First things first, I need to scavenge an engine crane off my brother in law and pull the engine out - I can then put it on the stand and turn it over to have a look at the crank proper - photos soon!

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...
