Ok, some progress. Got the pin out and took apart the distributor. Used a punch slightly smaller then the hole through the cog at the end and gave it a good smack. Then laid out all the parts, there are some washers that are like Dremel cutting discs. Does anyone know what type of washer that is one, if not both need replacing. Then the second hardest bit was removing the washer in the lip on the other side with covers the oil seal. As you can see from the pic (middle item) it has a serrated edge and is quite soft. I gently knocked it out from the other side. And the seal at the bottom, didn't look too bad but leaked alot so... Then the shaft. Looks like there is a groove where the seal should sit about 5mm up from the bottom. Gonna clean this up before refitting. The size i have gone for is indeed 12x19x5 and most places start 12.5mm x 22mm not 19 so it would be too big. I got some with a dust seal (left, you can just make out the lip on the inside) and some normal seals. Got them from Simply Bearings, very good service. Next day delivery and flat rate of postage of 1.25! Then i gently knocked it into the distributor, making sure not to go down too far. I check with the shaft to make sure the oil seal lip 'clicked' with the mark on the shaft to seal.
Excellent work done mine too , havn't fitted to car yet so fingers crossed it was the HALL that was the problem.
should i be worried? just replaced two of these seals in my spare dizzy's,gor the seals from simply bearings 12x19x5TC's (double lip) i didnt have to tap the seals in i was able to just push them in with my thumb i did have to tap the washer on though,but not sure why the seal was so easy
as long as you had some ristance when you pushed them in i would not worry the ones i tock out where like this but ones used to replace then with where tighter if it is going to leak it will do it quite quickly dont worry
thats just it tho i did it with my thumb so was a very small amount of resistance,the good thing was it didnt fall out,but was able to pull the seal back out easy enough with the shaft.i know the washer will hold the seal in but scared of the seal spinning, the shaft feels tight,as there 12mm internal diam as opposed to 12.5
19mm,there the same ones jonny recomended,the others i had from last time i misplaced them,i think they were 19 too well i suppose it can go two ways cant it,either will be ok or itl pi55 oil out
john any reason why you shouldnt go too far down with the seal,ive done mine as per pic above and theres a gap at the bottom
