The gasket that came off, was copper and yes there was a gap, but with the new gasket, which is made of some composite material, the gap is more extensive, indeed, there are places where the gap approaches 10-12mm.Quote:

Hey lads,
I am trying to source a set of head bolts to suit a series 3, 4 cylinder petrol engine.
I've managed to get the majority of them but the ones I am looking for are the, four short ones, located near the spark plugs.
I thought that maybe high tensile bolts from a local supplier would suffice,
But apparently, high tensile bolts have different grades.
So the question is, where can I locate the original manufacturers bolts, or failing that, what grade high tensile bolts do I need.
Thanks,
Norm.
What is wrong with your old bolts? They should be reusable...Quote:

Actually the block is a remanufactured short engine so there is no problems concerning threads in the block. The original bolts have 65 V 75 stamped on the heads.....?? and they are indeed stretched in that they are extremely loose in the threads. Incidentally, the cylinder is also a remanufactured unit, supplied by turners in the UK. so obviously I'm pretty keen to get things right..!Quote:

The bolts should be fine to reuse. When bolts stretch they stretch at the shank, not the threads,,,Quote:

As I say, I am only missing the four short bolts for the complete set..!
Hi,
I think it's land rover part 273356 which has been superseded by 279648. 1/2" x 2.5/16 long UNF.
google land rover 279648 gets plenty of hits in the UK. Or ring Four wheel drives in melb or Rover parts plus in Ballarat.

Hi lads,
In the process of my rebuild, I've struck trouble with a new clutch kit.
I went to fit it only to discover that the cover plate supplied, only has provision for two locating dowels, diametrically opposite, whereas my flywheel has THREE locating dowels, equidistant around the perimeter.
I've attempted to drill the two holes in the cover to line up, but of course the accuracy is questionable..!
On checking my order, it would appear that the part that arrived was to suit, series 1 & series 2.
Is there a difference between the series 2 & the series 2a..? I always thought they were the same.
Any ideas guys..?
Norm.
What year is your 2A?
I think late 2A and 3 are the same.
So maybe that is your problem.
Cheers, Mick.
The standard cover plate(GCC127) fits a 9" plate and uses coil springs and has two dowels. The clutch cover assembly for a 9.5" plate (GCC112) was optional equipment, and has three dowels. This assembly has a diaphragm spring, with a large number of fingers instead of three, and with a steel ring over them held by three tangential spring arms (if it has a diaphragm spring and does not have this ring it is a Series 3 cover (576557), and is no good to you!).Quote:

Your flywheel probably is drilled for the three dowels as well as for the two dowels, so you could convert to a 9.5" clutch. (dowels are 502116)
Hope this helps.
