Geko Posted August 27, 2019 Report Share Posted August 27, 2019 I'd love to read that the leak isn't related to a bent front engine plate Quote Link to post Share on other sites
TwinCamJohn Posted August 27, 2019 Author Report Share Posted August 27, 2019 How would that be bent? Quote Link to post Share on other sites

My 4a had one when I first had it and it always leaked a little oil until the engine was rebuilt a few years ago when it was discovered (it was only very slightly bent so not visually obvious and only discovered by using a straight edge) It had had a hard clump on the front before I bought it.

TwinCamJohn Posted August 27, 2019 Author Report Share Posted August 27, 2019 Well, I've had the car three years and this has only just started. No front end contact in my ownership ! Quote Link to post Share on other sites
Rodbr Posted August 27, 2019 Report Share Posted August 27, 2019 Hi John, Don't be fooled by the lack of oil around the pulley seal system as the air flow and fan make the oil go anywhere it likes. If you are having the apron off to get access to remove the radiator. Don't ask about torquing up the crankshaft bolt and the nightmares of the shims no shims debate. i wish yoyu luck sorting it out but get in touch if you want the definitive seal.

TwinCamJohn Posted August 27, 2019 Author Report Share Posted August 27, 2019 Rod, I cleaned everything up and with the car on the stands I ran the engine and saw the oil coming out of the bottom of the timing case gasket. I haven't seen the shims debate as up till now as that was someone else's problem. I'll take it all slowly over the winter. Well hopefully not all of the winter as that is a great time to be driving.

Stuart. Here's mine, bent a good 10 degrees. I drove it for ten years that way. The oil leak never seemed excessive. Tom Quote Link to post Share on other sites

TwinCamJohn Posted October 8, 2019 Author Report Share Posted October 8, 2019 (edited) Well, the work has begun. the apron is off. P1050661 by john curtis, sur Flickr Top tip. make sure all the bolts are out. It's a lot easier First thng is to get the radiator off for a repair. The bodge I did has lasted well, but this is an opportunity for getting it done properly. P1050672 by john curtis, sur Flickr Access to the crankshaft nut was restricted so I loosened off the engine mounts and jacked it up. I used the socket and bar against the chassis and flicked the starter and the nut was loose. P1050670 by john curtis, sur Flickr The pulley is resisting and I can't get a three leg puller in. Have just ordered a two leg version and that will be here shortly Have ordered another fitting kit for the electric fan as these had to be cut to take it off the radiator. https://www.revotec.com/acatalog/Fan-Pull-Through-Kit.html#aFPK01 More later Edited October 8, 2019 by TwinCamJohn Quote Link to post Share on other sites
Rodbr Posted October 9, 2019 Report Share Posted October 9, 2019 Hi john, Did you get the details of the double lip seal I sent you, Highly recommend that you go for the Viton version. I note that you have not removed the steering rack, I am sure that you will need to do this the allow the crankshaft bolt to be withdrawn and get access to the pulley. I am surprised that you need a puller but they are a little tight. As regards the Easi sleeve issue these are available from different sources under different names and are at least half the cost of the GKN item or through Moss etc. Try to check out agricultural suppliers or Engineer supplies, The Hayley group are the ones I used and they have outlets over the UK. Take the item in and they can supply. They come with the fitting collar and work exactly the same as GKN one. Even if the pulley looks OK it is worth while fitting a sleeve as a belt and braces solution. used on Half shaft and crankshaft pulley to great effect. About £12.00 each.

TwinCamJohn Posted October 9, 2019 Author Report Share Posted October 9, 2019 hello Rod. No details received; You asked me to contact you when I had removed the pulley and measured the shaft. The crankshaft bolt came out with no problem. However, the pulley is resisting even with a puller. Quote Link to post Share on other sites

BlueTR3A-5EKT Posted October 9, 2019 Report Share Posted October 9, 2019 (edited) Does the LH foot of the engine mounting plate where it fits to the mount by the steering shaft look bent to any one else? The crank pulley looks like it has two theraded holes in it for a pair of extractor bolts to fit into. - Be careful with a legged puller for fear of pulling the outer rim off the inner. Like this thing that will also do a classic Mini clutch/flywheel. https://www.summitracing.com/parts/oes-27019/overview/ Peter W Edited October 9, 2019 by BlueTR3A-5EKT Quote Link to post Share on other sites
TwinCamJohn Posted October 9, 2019 Author Report Share Posted October 9, 2019 (edited) Firstly, there is no bend ! The steering mounts have been loosened to allow for jacking the front of the engine up. Yes there are threaded holes but as you can see from this picture they are covered by the centre "piece" in the pulley. Thing is, it won't come off and I'm not sure what it is. If it's a thick washer then I should have been able to prise it off and I can't. Is it separate ? If not then I can't access the bolt holes. I do have one of those "duck's foot devices but it is too big.

TwinCamJohn Posted October 10, 2019 Author Report Share Posted October 10, 2019 I have spoken to Moss and they say it is a flat washer. I really don't think it is, although they should know their parts ! In the second picture you can see that the internal depth of the "washer" is greater than the thickness you can see on the extérieure. So maybe it goes in side the pulley a little way. In any case it won't come off. Any thoughts ? Quote Link to post Share on other sites
Fireman049 Posted October 10, 2019 Report Share Posted October 10, 2019 Have you tried 'shocking' it off with a hammer and drift? Tom. Quote Link to post Share on other sites
TwinCamJohn Posted October 10, 2019 Author Report Share Posted October 10, 2019 Yes, I have but I don't think it is a flat washer or it would have moved by now ! Quote Link to post Share on other sites
keith1948 Posted October 10, 2019 Report Share Posted October 10, 2019 Hello John Suggest you heat up the pulley with a blow lamp and as it cools run penetrating oil around the washer. Repeat this a few times. Also tap the washer with a hammer as it cools to try to shock the joint between the parts to help the oil get in there. I am told that diesel is also a good penetrating fluid but not tried it myself. It will most likely then suddenly come free and you will be left wondering why it was so hard to move in the first place. Keith Quote Link to post Share on other sites
TwinCamJohn Posted October 10, 2019 Author Report Share Posted October 10, 2019 I can't do that as it is a damped pulley. Has anyone got this Moss conversion to narrow fan belt without the fan ? Quote Link to post Share on other sites

TwinCamJohn Posted October 10, 2019 Author Report Share Posted October 10, 2019 This is the Moss kit which was fitted by the previous owner. https://www.moss-europe.co.uk/narrow-belt-conversion-kit.html The washer in the picture seems to be just that. But referring back to my last picture it seems to be stepped? Quote Link to post Share on other sites
TwinCamJohn Posted October 10, 2019 Author Report Share Posted October 10, 2019 I have tried tapping the washer round anti clockwise and also bent an old screwdriver to get in behind it. Still nothing. have retired for the night now having given all a good soaking with WD40. Quote Link to post Share on other sites
Chilliman Posted October 11, 2019 Report Share Posted October 11, 2019 Just as a matter of interest - whereabouts are you locating the centre pin of your new two leg puller? I would have thought that if you re-fitted the main bolt & screwed it in all the way & then back it off a few mm, put the centre pin of your puller against the head of the bolt & tighten a little the whole lot - pulley & washer (or whatever it is) would slide off together without any great effort?

Mick Forey Posted October 11, 2019 Report Share Posted October 11, 2019 When I did this operation a few years back I moved the rack, not hard, and removed the cross member so I could get good access. I used a three leg puller with the centre against the previously loosened crank bolt. Tightened up the puller bolt as much as I dared, then hit the end of the puller bolt with a lump hammer, pop, the pulley came off. Hope you get it off one way or another.
