crankshaft pulley wobble
Discussion
Right the pulley actually moves so should it? Feels like there is some play and I guess it moves 2mm when I move it side to side. Also there are only 3 bolts in it but 6 holes - is this correct?
It looks like this BTW:

Should I change the pulley or will I need to get it all balanced or just change the pulley bolt? Yes, I know the bolt needs be done by a specialist who has a ramp and can apply the appropriate force.
I put a picture on my earlier post which may clarify things.
David Gerald is about 2 miles away.

Pretty much what Carsy said, pull it off check it all out, maybe ARP make a crank bolt if it worries you, it worried me after I saw Barry's and got arp on my engine now
Alex,Where would I get the ARP bolt from and is it a direct replacement? Do I need any washers or any other kit with it?

The stock LR is not the problem

h that's unusual then 
Presumption ... the mother of all f
k up's 
sorry about that FFG 
: should be just a pulley and bolt change (if the pulley is worn) and a crank nose and keyway inspection then 
Not a problem, we have a 500 too. Presumption ... the mother of all fk up's sorry about that FFG : should be just a pulley and bolt change (if the pulley is worn) and a crank nose and keyway inspection then I did say it was the precat early in the post. it has done 250k miles so things do wear.

Rubbish picture (was very early and dark in the garage):
I've seen some with the serp belt piece between the 2 v belt pulley section, similar to teh one below. They all look about the same legth so maybe I'll be OK getting one similar as a back up if I need one.

Mine doesnt have the big lump at the back end with the groove in it or the smaller doughnut pice nearest the engine.
This was the one I was looking to buy as the spare:

Have you got the damper and pulley off yet ?
I wouldnt go buying anything until you have them off and you have inspected them to see exactly what the problem is.
Chances are it will be the rubber in the damper that has failed. Buying second hand you may well buy something as bad as what you already have.
You are right, the pulley nearest the engine is not used on our cars so as long as there are no external balancing weights welded into it as on the 500`s it isnt really needed. Mine didnt have anything welded to it and i no longer have it fitted.
I`m pretty sure the 430 crank is a Rover item and not TVR specific.
Thanks. Car still in my garage but booked to go into David Gerald next Thursday - it Easter this weekend so they are busy and closed for a few days. My pulley doesnt look great and the suggested one looks brand new in comparision - only £20 delivered.

I felt the bolt this morning but cant really tell if it isnt 100% tight so will get a socket on it tonight to see. Hopefully it'll be simple and cheap.

The 500 is externally balanced. I'd be vary careful about removing and adding pulleys. I want to use an after market ECU and the advice about adding a trigger wheel to the pulley was get the whole thing dynamically balanced first, otherwise you can risk a snapped crank.
Its the 430BV not the 500.FFG

I found the problem. I have a enormous play between the pulley and the crankshaft (couple of mm and at least 10 degrees when rotating) so much that the oil leaks between the key and pulley. I think the crank and pulley are scrap. For now a take a bottle of Johnny Walker and after that I go to talk with the bank manager that I need money for a new bottom end.
My pulley bolt was tight but as someone had added a shim behind the damper it wasnt pulling the damper and pulley tight enough. The shim was aluminium which isnt the best meterial and it had gone out of shape, the key had mainly disappeared (thank god for the big magnet on the oil filter), and the damper had seen better days, all contributing to the problem. Up shot - new shim, crank is OK (thankfully), new damper (SD1 so 6 x the 500 damper cost), new key designed as the standard one just kept slipping along the keyway, and as the damper assembly was slightly further out also needed a shim on the water pump pulley. No metal in the sump which is good. All new fluids/filters. Over a grand spent but could have been much worse.
Thats 2 big bills in 12 months and I've covered about 250 miles!!
I didnt have an oil leak so yours must be worse. Good luck.

I worry that you may have a problem Paul, best to check with Dom + if/whoever did any frontend/cam work. IIRC 430 with std cam gear (non-vernier) has an alloy shim (about 5mm) up against the front (nearly next to main bearing cap) that the cam chain sprocket sits on. Always assumed this was a workaround with the particular crank being inbetween short/long nose for the serp changeover, never paid much attention just always made sure particular cam gear has sprockets lined up & clearing timing cover (various cams + timing gear seem to have subtle differences).
If the shim has been fitted in the wrong place it could be pretty awful on the cam chain, I'm not sure but I'd suggest checking with someone.
Got me worried now so e-mail sent to repairer. It runs OK and seems to rev and pull better than before, but does sound a bit like it has a supercharger now with a slight whirring sound.If the shim has been fitted in the wrong place it could be pretty awful on the cam chain, I'm not sure but I'd suggest checking with someone.
I thought the alloy shim was a bodge TBH.
