mazfg Posted March 6, 2013 Share Posted March 6, 2013 Just been reading up about re-fitting a distributor and note about the pedestal gasket....I see that paddocks do 2 pedestal gaskets 0.006" and a 0.020"....can someone explain what's required. Having taken off my distributor, I found there was no gasket? Quote Link to comment Share on other sites More sharing options...
Nick Jones Posted March 6, 2013 Share Posted March 6, 2013 Gaskets are used more as shims as the pedestal position determines the end-float for the distributor drive gear. If there was no gasket in there before (have a gentle scrape to make sure - they can be quite hard to spot) then you don't need one now - just a thin smear of silicone or Hylomar to seal.Nick Quote Link to comment Share on other sites More sharing options...
mazfg Posted March 6, 2013 Author Share Posted March 6, 2013 Thanks Nick for that...will double check the distributor pedestal mount tomorrow....Haynes says endfloat should be between 0.003 & 0.007"....so guessig the 0.006 gasket would be the option, if I needed it. Getting a new camshaft so may need re-investigating ?? Quote Link to comment Share on other sites More sharing options...
Casper Posted March 7, 2013 Share Posted March 7, 2013 Quote:guessig the 0.006 gasket would be the optionNot as simple as that. Haynes doesn't describe it well, but you need to determine the endfloat/preload without any gaskets, then add gaskets to suit.C. Quote Link to comment Share on other sites More sharing options...
mazfg Posted March 7, 2013 Author Share Posted March 7, 2013 I've just checked and found a very thin gasket on there....... Due to a new camshaft being fitted, i guess it may change? Quote Link to comment Share on other sites More sharing options...
sparky_spit Posted March 7, 2013 Share Posted March 7, 2013 The gaskets are very cheap so it's worth buying several. You can then cut a gap out of one to allow you to check end float with the tip of a feeler gauge in the gap. When you have it correct, use a new complete one of the same thickness.

mazfg Posted March 7, 2013 Author Share Posted March 7, 2013 Mmm, I a bit baffled now.....having taken off and recorded the position with photos of the distributor with no.1 cylinder at TDC compression/ firing stroke...the rotor arm was pointing to no.6 cylinder... It's liek it was 180deg out.......now the car was running before....(did lack power) but I would have thought that 180 deg out would give nothing?

Pete Lewis Posted March 7, 2013 Share Posted March 7, 2013 has no bearing on running IF the leads have been transposed in the cap , and if the drive dog is a bit worn its been known to misfit the offset the set up in the manual for the drive gear indexing is as much to do with getting the vac unit to not foul up and have no room to rotate the body for setting the timing.Easter is comming put a OE reprint ( or jumble) workshop manual, on a wish list .... or we sell heritage CDroms in TSSC shop which has all owner/parts lists/workshop manuals for all herald and vitesse for a few �s all in one diskPete Quote Link to comment Share on other sites More sharing options...
mazfg Posted March 7, 2013 Author Share Posted March 7, 2013 The leads haven't been transposed. They all go to the correct places, it's just the rotor arm is set for fireing when I'm TDC on no.1 compression/ firing stroke. All I can think of is, could the camshaft be 180degrees out, therefore no.6 cylinder is on compression/ firing stroke at TDC? As far as i could see, the cam sprocket matches the markings on the camshaft... Quote Link to comment Share on other sites More sharing options...
Nick Jones Posted March 7, 2013 Share Posted March 7, 2013 Cam change shouldn't affect the dizzy drive gear end-float.Nick Quote Link to comment Share on other sites More sharing options...
junkuser Posted March 7, 2013 Share Posted March 7, 2013 The meshing of the gears on the distributor drive shaft are 180 degrees out would be my guess. Quote Link to comment Share on other sites More sharing options...
mazfg Posted March 7, 2013 Author Share Posted March 7, 2013 The thing is, it was running at that before.....? Quote Link to comment Share on other sites More sharing options...
junkuser Posted March 7, 2013 Share Posted March 7, 2013 When you dropped the distributor shaft back in after the camshaft change how did you judge the position to introduce it mazfg?Did you allow for it rotating as the spiral gears meshed?

mazfg Posted March 7, 2013 Author Share Posted March 7, 2013 Haven't done the camshaft change yet, still got the original in./...this is all since I removed the distributor..hence taking a record of it as I took it out. Quote Link to comment Share on other sites More sharing options...
junkuser Posted March 7, 2013 Share Posted March 7, 2013 Sorry for my misinterpretation.Whilst the drive dog on the distributor is eccentric, there was a posting some years back, where someone had managed to get the distributor to fit 180 out.Don't know how that could be done. Maybe very worn components. Quote Link to comment Share on other sites More sharing options...
mazfg Posted March 7, 2013 Author Share Posted March 7, 2013 As a question though.....Is it possible to have the cam 180deg out from no.1 tdc and the distributor also out by 180 deg, would the car run. So in theory firing on no.6 cylinder? Quote Link to comment Share on other sites More sharing options...
