trouble understanding the torsion tie plate removal

Hi Just in the process of taking out the engine/clutch/gearbox assembly and am now at the tie plate removal stage, which has me a little perplexed. Perhaps someone can help my understanding. From the service manual : "Remove the nuts securing the torsion bar reaction tie plate on each side and tap t...

Thanks Peter Circumference was calculated from tyre dimensions - I might just get a tape measure out to get more accuracy :D I did think the speeds looked somewhat on the optimistic side, but not far out. I put this down to being purely simplistic mathematical calculations without taking into accoun...

Excellent. I'm glad you found the problem.


And thanks to Peter and Geoff for correcting my perception of the propshaft.

Now if only I could work out where the noise is coming from on my backend :)

Hi Geoff Surely they are all related to each other. Engine - gears - prop - diff - drive - wheels just with different ratios. So there is always a correlation between RPM and prop / drive etc. as well as prop to road speed. I fully agree, the prop will be turning at a different speed at 3000rpm in t...

Is it revs sensitive or speed sensitive? e.g. if above 3000 revs in any gear you always get it, it is probably prop/drive shaft related. Check simple things like the bolts on the prop shaft ends are tight. I've seen them become loose and cause this. If it is above a certain speed rather than revs, m...

seems the calculations are pretty close. If you had a .63 you would be cruising at 133 mph - although not quite sure that would be classed as cruising in the e-type.

Critically though, it keeps you in the optimum power band, although with the .63 you could have done the same speed for 700 revs less.

How much foam / Dynamat is needed between the gearbox and the body? 2 inches thick but how large? Does anyone have any pics of an install to give an idea how far down/around it needs to go?

standard rate is about 140 CHF / ?100 per hour for mechanicals - it will be cheaper to buy my own lift... if only I had the space :mad:

Also, doesn't guarantee it will get out the shop any quicker.... but hey... the clock is working :bigrin:

New owner introduction

Hi all Last month I took delivery of a lovely 1969 OTS in Regency Red and officially became a big cat owner for the first time. I knew there would be a few things to do, but closer inspection etc. has revealed the usual long list of PO bits and pieces to fix. Biggest one was the clutch failing, so h...

Are the gearbox mount bobbins the same as the engine mounts? I can't find them after looking in several of the catalogues.

I was about to do mine also. I added the Gear lever bush to the list as well - not sure if it is strictly necessary.

I had similar problems. A light strip down as per the Smith-Jaeger repair link posted by Andrew, and some light greasing (also on the cable sleave) fixed the issue.

Thanks Peter and David It's already in danger of turning into a restoration :wink: Looks like there are hairline cracks in the exhaust manifolds which will also need replacing.

S2 replacement radiator

Hi all It looks like I am going to replace the radiator on my S2 OTS, several mangled bits on the cooling fins, tell tale signs of previous patching and congealed green coolant in various places. I thought I might as well go with an uprated one, as I will be using it as a driver in standing traffic,...

Jobs whilst engine is out

Hi all I've just got a 1969 OTS, was at the Swiss equivalent of a VOSA test to get it on the road and the clutch totally failed :sad: compression on the pedal but not disengaging. Cylinders look ok, but now taking out the engine to examine the clutch. We've seen there is a crack in the bell housing,...
