Your pins are tight in the pistons because they're cold. Put them in hot water or better still your parts wash. When hot they're loose. If they're loose when cold they'll be even more loose when hot.

I’m reliving my experiences with the old school methods you’ve been explaining. My proudest moment being a straight six Rover block, hand honed everything, ran as sweet as a nut. Patience is king.

When checking ring gaps with flat top pistons I was taught to put one ring on the piston so when you have your ring in the bore push it down with the piston upside down until the ring on the piston is touching block, ensuring the ring to be checked is square in the bore

@jamesplotkin4674

Learned this technique back in HS. Not only square, but a bit less importantly, the same distance down the bore. Consistent measurements assured.

what a pleasure to see the Lagonda. What an old piece of history!!! AWESOME!!

I'm surprised to see the gudgeon pins for those pistons sliding in/out when the piston is cold. When I rebuilt an engine with new pistons, one had to warm the piston up slightly, to release the gudgeon pin.

I noticed the piston circlips are the stamped "eye" type. Being stamped they have a rounded edge and a sharp one. Years ago I rebuilt a perkins 4203 engine and didn't check the orientation of the circlips. Apparently they should be fitted with sharp edge towards the bore wall. I didn't know. Sure enough a few years later a circlip ended up in bits and scored up the bore either end of the gudgeon pin. Had to fit another liner etc. You probably know anyway.

Rule of thumb that will never let you down is : most plain bearings are 0.001" per inch of journal, so a 1 &1/2" journal is 0.0015 " water cooled piston rings are 0.001 ' per 1 " of bore, BUT ! you must multiply the bore x PIE ( 3.172 ) to get the circumference length, so a 3" bore x PIE = best part of 0.010" you have to double this for air cooled pistons rob NZ

Thank you for showing us how you are working on that Lagonda engine. Quite informative

Very interesting again, like the diy gapping technique, interested to see the wet/dry nut/split pin alignment technique

Really enjoyed that well done guys.

Hi Love that lagonda crank it makes a modern one look like a bent bit of wire Must feel like a privilege to be entrusted with a piece of history

This is a good and sound way to gap rings without special tools. Our gapping tool is quite expensive for a hobbyist. I started with this file technique decades ago. I moved on the rotary gapping tool. We now have the "state of the art" device to take care of that task. It is not a tool for those that will build 2 or 3 motors a year. You have done a service for those that want to work within their means. Great job. Have a deluxe day! looking forward to seeing you Friday!

Ageless!...Unbelievable...thanks V/Much.

This is a great KZread channel.👍

love the old school ring gapping seems the right way for an old engine like the Lagonda!

A great job there and so interesting

What a gorgeous old long stroke engine. Looks so strong and industrial! Would have thought the ring gaps would be a little bigger than you suggested at .005" Used to have a rule of .003" plus per inch of bore for liquid cooled engines and the bore looks to be 3" or more. Air cooled even more. Also a bit curious as to the gudgeon pin fit in piston . Always warmed the pistons up in very hot water prior to fitting to conrods and the pins would slide in beautifully and would be free floating when engine was hot. EDIT I miss heard the ring gap and thought you said 005" not 012". Apologies for that error.

Brilliant channel, I love the work you do. Subscribed and loved.

We call that white metal bearing babbitt bearings or the process is called babbitting over here in the States. It is an art we are slowly losing to time.

Not strictly necessary if the rings are of cast iron, but chalk certainly helps stop the file from loading up for steel rings.

Nice to see the white metal bearings as I did my own white metal ( Babbitt) bearings on my 1934 SS2 , very satisfying but took me about 2 weeks to scrap them all in 😂 , happy days 😀😀

Back in 90, I used to do Dorking market and one of my loyal customers a terribly suffering old gent with his missus would talk for a bit and in the end I asked him about his many apparent injuries and he says to me "Oh I used to work in the car business" so I am thinking he must have had a major industrial accident or something and said so and he was "oh no, I was Aston Martin's crash driver" and he explained to me how he would be paid quite a lot to literally drive cars into brick walls, other cars, off high edges and at some speed too and he had broken every bone in his body more than once. He bought a huge house and lived in quite some luxury on what he was paid lol

There must be a torque tolerance for the crank shaft big end journals? If so you can go to that torque setting to see if the split pins line up? Then you don’t need to touch the nuts.

@nmetcalfe506

No mention of balancing that huge crank. Would be wise, wouldn't you agree?

Just out of interest, who did you use to remetal the bearings? They guy we used to use retired and I'm looking for recommendations.

Rather than a split pin in the castellated nuts, would you not wire-lock them like an aero engine?

Damn! I still do ring end clearances this way! You mean there is a better way?

Nice engine. How are the thrusts set up on it? Did you get any pictures of the old bearings and crank? The wear can tell a story, but to me that is some kind of aftermarket crank, but I am not familiar with the inards of a that legonda engine. I have a couple of 1930s Meadows engines that'll likely need similar TLC once I open them up and see how they are set up, and then rebuild similarly, so this has given me a bit of a spur to dig them out of the back of the shed and get on with it. For gap measuring, just use an inverted piston with a ring in it to push the test ring down the bore. It stops square, easily & quickly. For filing a simple tapered jig to hold the ring flat and lightly squeeze it in and block holding the needle file nice and square works well, unless you have a wheel turned ring-gapper tool that makes the operation a cinch. Is next weeks lesson on hand scraping bearings or even face scraping to flatten the block or head if you have a power cut? All nice and theraputic if you have all the time in the world, and a good referencing tool...

As the supplier of the crank I can assure you it’s completely original by our estimations it just hadn’t been in anything for a good few decades took me a fair while to clean it up but just depending on use will affect the clearance sizes.

Don't you check the piston pin end gap?

Wet / Dry papering the bottom face of the rod nuts in order to have the castellations on the nuts to line up with the holes at the proper torque.. Now if that doesn't prove to you that the quality of the work that this shop turns out is impeccable, nothing will prove it to you. Some other shop would have either tightened or loosened the nuts a bit in order to get a cotter pin inserted.
