Title: B20 Basic maintenance Post by: timdaw on 09 November, 2023, 04:25:35 PM I'm new to the B20 and am finding some everyday maintenance and basic stuff challenging...stuff which is easy on other cars! I have the workshop manual but it has some omissions.
I'd be very grateful for some guidance on the following please: 1. How best to rotate the engine when adjusting points, and where are the timing marks to be found? 2. Where is it best to jack the rear of the car? Thank you. Title: Re: B20 Basic maintenance Post by: impaw on 10 November, 2023, 12:15:40 PM Hello Tim!
I´ll try to answer a couple of you questions The flywheel has a tiny "0" stamped on one of its teeth. It can be hard to spot if the flywheel is dirty. Clean and perhaps accentuate with a dash of white paint? This mark should line up with 1 I 4 on the flanger of the engine, when piston #1 is at TDC. When you time the engine with a strobe light it should line up with A A Regarding turning the engine, there nut on the crankshaft pulley is 22mm, if you can reach it (my engine is out of the car, so I'm not sure if it is possible to reach it with the radiator in place). Title: Re: B20 Basic maintenance Post by: williamcorke on 10 November, 2023, 06:18:06 PM Hi Tim,
Jacking question. Depends on what you're jacking the car up for. The jacking point in the sill with the standard jack is a surprisingly effective way to get both the wheels on that side off the ground if wheel removal is your goal. Alternatively, the mounting points of the trailing arm (where the the big bushes are) are solid enough to take the weight of the car and I sometimes jack up the entire rear of the car with a high-lift trolley jack under the transaxle (with a wooden block to protect the aluminium casing). Others may disagree with my choices! Best, William Title: Re: B20 Basic maintenance Post by: timdaw on 16 November, 2023, 09:59:47 PM Thank you to William and Torstein for your replies.
I see that this post has been read over 200 times, but only 2 replies. Does nobody maintain their own Aurelia? Title: Re: B20 Basic maintenance Post by: williamcorke on 16 November, 2023, 11:23:05 PM Good question Tim. There are a few of us here who do maintain and restore our own Aurelias. I think owners who don't get hand-on into the engineering and construction of these lovely cars are missing out on a lot of the fun, but each to their own.
I'm sure we'd all love to hear more about your S3 B20. How long have you had it, and what was your 'journey' to Aurelia-land? Best, William Title: Re: B20 Basic maintenance Post by: chriswgawne on 17 November, 2023, 09:35:48 AM I dont think Aurelias are particularly complicated and so maintenance is similar to other early 1950s vehicles.
There are lots of greasing points, some of which are a bit of a pain to get to but nevertheless are worth doing at least once per year. I have a couple of period SHELL greasing charts which I can photo and send you if you wish. Oil changes - I always use Mobil 1 10/40 and change every 3 to 5,000 miles even if the oil still looks clean. On all our Aurelias I have converted the oil filter to a full flow modern canister type BTW. Engine coolant - keep the antifreeze % content up to minimize corrosion. Brakes - use the car regularly to avoid rear wheel cylinder leaks - they are a pain to change! Brake shoe adjustment is occasional as the front shoes are so large, particularly on the 2.5l cars. The rears hardly wear at all Ignition points - Its important to have the points accurately set 180 deg apart and also that the distributor itself isnt badly worn. Hope this helps. Chris Title: Re: B20 Basic maintenance Post by: chriswgawne on 17 November, 2023, 06:15:22 PM I see you have a S3 B20 - does it have the original 'Lancia' lever arm shock absorbers? They are beautiful things with quite a range of adjustment but over time they can leak around the main shaft. Important to keep the level maintained with the correct sort of fluids which I believe are detailed in the manual.

Best, William Hello William, I bought the car just a couple of months ago. I used to have a 6th series car, which I bought about 25 years ago and owned for a few years. I did some long trips in it, including London to Basel via Le Mans 24hr. I've hankered after another one in recent years and have always considered the B20 to be one of the most beautiful designs ever, both aesthetically and technically. The one I bought was restored at vast expense by Omicron...pretty much everything done, including engine rebuild, but its not without its faults! I've always looked after my cars, primarily Porsche 356's, but also Alfa Giulia SS and Giulietta Spider Veloce, as much as possible as I enjoy having an input into the car. I'm finding the Aurelia a bit intimidating though! Paul Mayo's manual is very helpful of course, but it is missing some basic stuff for 'beginners' with the cars. Best wishes, Tim Title: Re: B20 Basic maintenance Post by: timdaw on 18 November, 2023, 02:04:39 PM I dont think Aurelias are particularly complicated and so maintenance is similar to other early 1950s vehicles. Hope this helps. Chris Hello Chris, Thank you for your helpful response. The first thing I did on the car was to familiarise myself with the greasing points, which as you say are many! I also changed the engine and gearbox oils, topped up pot joints. I drained some water off and introduced plenty of anti freeze. The brakes squeal a bit at first, but are fine when they are warmed up. I intend to use the car regularly and agree that this is important. The rear shocks had been modified to telescopics long ago. It's fitted with Spax, which I'm not a big fan of. I prefer Koni, but I'd have to have some specially made by them. I would love to see the Shell greasing chart if you don't mind please. Best wishes, Tim Title: Re: B20 Basic maintenance Post by: chriswgawne on 18 November, 2023, 02:57:16 PM I have a pair of rebuilt early 1960s (by Koni) telescopic Konis but I think are for 4th srs and later I believe. What min/max lengths do your Spax open/close to?
Here are poor photos of one of the Shell charts I have.

Like Tim, I'm new to B20 ownership (be gentle!) and I've recently joined the club. 'My' car is WPD10 which is fairly well known in the club I think. Actually - 'ownership' sounds a bit overblown in this case. I've taken it on after my dad John passed away last year. Really I consider it to be my dad's car and that I'm just looking after it so I want to do a decent job! My first job for winter is fluid and lubrication check/replacement but otherwise it's in pretty good fettle in the short term. First basic question - hence the use of this thread - can anyone recommend an antifreeze? My dad left a lot of notes about the car (some of it researching suitable antifreeze types) but I can't find his conclusion. Is there something specific to use that will inhibit corrosion? Or just some general good quality stuff? Anyway - I look forward to B20 disucssions - and thanks in advance, Alex. Title: Re: B20 Basic maintenance Post by: lancialulu on 30 November, 2023, 05:49:32 PM Hi Tim
I knew and respected your Dad for his extensive engineering knowledge not restricted to Lancias. We exchanged ideas on such matters of Aurelia suspension (I have a B12), and I was sad to hear he passed. We did not discuss antifreeze but if we would have done I am not sure we would have agreed but maybe. Anyway I have found empirically the blue glycol based anti freeze at 50% concentration seems to give protection to corrosion. I use this in my other Lancias as well as my B12. I think, but could be wrong, but blue glycol based is same as Lancia specified called Paraflu. Good luck with your custodianship and welcome to LMC!

Alex - As you well know, your father was a good friend to me, and tutored me on many engineering subjects, of which crankshaft design was only one. His restoration of the now "family" B20 was exemplary, and you are very lucky to have such a fine example. If there is anything you need help with, feel free to ask.

Geoff Hi Geoff, glad to hear from you and yes I certainly remember when my dad was working through such subjects as crankshaft balancing (and many others) with you, making sure he had everything right and sketched up nicely at each stage. I know he enjoyed those conversations with you veyr much and it certainly kept his brain in good order! I do appreciate how fortunate I am with the car, and intend to make sure it's well looked after and well used. I'm sure I'll be in touch in due course with more questions! Thank you.

Hello Alex, How nice to hear that you have taken on the ownership of such a historic B20 from your late father. I remember reading the road test of the car from 1955 when Mike Hawthorn demonstrated it to a journalist, with a rather large Alsatian sat on the back seat! I don't suppose there are any dog hairs left in the car!? It was one of the things that attracted me to B20 ownership. My recently acquired car is my second. Great to hear that you intend to maintain it and, importantly, use it! I second the use of Blue antifreeze as being correct for the alloy engine. As with you, the first thing I did when taking on my car was to change all fluids and give all the (many) grease points attention. There is a guide to the correct oils in the Paul Mayo manual, if they are not in your father's notes. Also, Classic Oils at Bicester are very good on providing information on lubricants for old cars. They do a good range of Penrite engine oils which are of high quality. Looking forward to seeing the car, and you, next year!

Title: Re: B20 Basic maintenance Post by: timdaw on 24 December, 2023, 10:19:20 AM As no one answered about how to physically turn the engine easily, I found an answer myself. The answer is the starting handle. Presumably a lot of Aurelia owners will be missing their starter handle as I was. With the kind help of Chris Gawne, I found an anonymous one on ebay (for £18 including postage) that works perfectly. The bar should be 13mm dia and about 600mm (very long) in length to the 1st bend.
The cross pin (which engages the crank pulley ) is 28mm long, end to end, and 6.5mm diameter. I think my one may have been for something like a land rover, it certainly doesn't have to be a very expensive and rare Lancia one. Of course you can only turn the engine clockwise, but then I think that you are not supposed to turn it anti anyway? |
