jagnut66 Posted May 9, 2023 Report Share Posted May 9, 2023 Hi, As the title states I've run into a little hiccup. I ordered one for my (ex - Spitfire) 1300 engine along with other bits, they duly arrived and I've been picking from the pile as needed. However, when it came to the Crankshaft front oil seal I found it was too large for the hole. It looks the same as the one I "persuaded", after God knows how long in residence (it was like it was welded in place), out.... But it sits on the hole and the diameter appears to be 1 or 2mm too big to be driven into it. I clearly remember requesting the correct one from a certain well known supplier, however, I'm left wondering whether I should have been clearer...... I shall ring them tomorrow and discuss it. In the meantime I wondered whether anyone else has had this issue and whether I need to be ordering a specific item, to ensure I get the correct size?? Best wishes, Mike.

Josef Posted May 9, 2023 Report Share Posted May 9, 2023 1147 and early 1296 engines take 100499 (listed as ‘small’ by Canley) Late 1296 on take UKC1110 (‘Large’) If that helps? Is there a part no on the packaging? Link to comment Share on other sites More sharing options...
jagnut66 Posted May 9, 2023 Author Report Share Posted May 9, 2023 Packaging shows 100499, so now I'm really confused, unless someone put the wrong part in the bag? It's definitely too big for the hole..... If they send another and it's the same I suppose I could try putting it in boiling water and see if that makes it malleable enough to squeeze in..... Best wishes, Mike. Link to comment Share on other sites More sharing options...

It's very firmly in place, I had to use heat to 'extract' what I did....... Best wishes, Mike. Link to comment Share on other sites More sharing options...
johny Posted May 9, 2023 Report Share Posted May 9, 2023 well spotted! Im sure the cover is just one stamped sheet of steel do there shouldnt be anything else in the seal well. Cant understand why its in so tight though and now its going to be difficult to get out without damaging the cover. All I can suggest is to drill a small partial hole(s) in the front of the cover lip and tap through with a small pin punch. The holes wont matter after as theyll be covered by the new seal...

Best wishes, Mike. yes it should be a smooth hole that is why it is fitting perfectly for the first mill or 2 then getting stuck Link to comment Share on other sites More sharing options...
DanMi Posted May 9, 2023 Report Share Posted May 9, 2023 I would try carefully getting a small screwdriver under the side of that bit until it is bent enough to grab with long nose pliers Link to comment Share on other sites More sharing options...
sulzerman Posted May 9, 2023 Report Share Posted May 9, 2023 (edited) Yes, looks like the remains of the old seal. Screwdriver and hammer job. Edited May 9, 2023 by sulzerman Link to comment Share on other sites More sharing options...
johny Posted May 9, 2023 Report Share Posted May 9, 2023 Reckon its really going to be stuck with melted rubber now🙁 Link to comment Share on other sites More sharing options...
Josef Posted May 9, 2023 Report Share Posted May 9, 2023 Grind a bit of it out maybe with one of those tiny dremel grinding bits? Then it might be easier to prise out the metal if the circle of it is broken. Link to comment Share on other sites More sharing options...
johny Posted May 9, 2023 Report Share Posted May 9, 2023 I suppose you could cut through both the old seal and the front of the cover with a hacksaw blade through the hole as long as you dont damage the seal 'well' wall which must maintained intack to prevent oil leakage....

jagnut66 Posted May 9, 2023 Author Report Share Posted May 9, 2023 A close up makes what you are saying even clearer... I had to use heat, as it was rock solid. I thought this metal was an inner lip. I wonder when it was last changed?..... Well now I know it needs to come out I shall have to set to it, Best wishes, Mike. Link to comment Share on other sites More sharing options...
Puglet1 Posted May 9, 2023 Report Share Posted May 9, 2023 Could try tapping the lip diagonally in towards the centre of the hole with a small, sharp cold chisel or centre punch. Once you have an inward facing lip, you can carefully chisel a cut downwards. Repeat this action about 20mm around the seal and you should be left with enough inward facing material to grasp with mole grips. Link to comment Share on other sites More sharing options...
jagnut66 Posted May 10, 2023 Author Report Share Posted May 10, 2023 Thanks for the clarification on this folks. I will know for next time. It is now out, due to the application of a screwdriver (metal topped / designed to be hammered) and the mechanics friend, the trusty hammer. The new one is now in place with the aid of a smear of red rubber grease to smooth the way. Many thanks, Mike. 1 Link to comment Share on other sites More sharing options...
johny Posted May 10, 2023 Report Share Posted May 10, 2023 Great. Now just need to check the rotating surface where the seal runs. Think this will be the front pulley on your model and it shouldnt show any significant wear because otherwise theres more chance of a leak...
