S2C Cutaway 2.25 Petrol Engine resurrection

[diffwhine]

Managed to get some limestone paint to stick to the inside of the crankcase today.
We will start painting the outside of the block later this week and then start building up the block.

Probably one for JonB or AlexB. I'm after two crankshaft thrust washers for the 151 engine. I see they are different to later ones although I haven't measured or checked. Anything rattling around in anybody's scrap parts pile for an early engine?

The other thing I need is the grub screw that holds the distributor drive bush behind the oil filter housing.

Limestone is a pretty close match to the crank case colour, so that little game worked. Bolted the crank in to keep it out of the way. I put the oil pump loosely in as well - damn thing keeps getting in the way and won't stand up on the bench.

Main paint job starts soon!

I have some used standard size thrust washers from my series one 2 litre engine, not sure if they are the same? Got any part numbers or an image I can compare with?

Will you see the thrust washers once fitted? Just wondering if you really need them.

Miles different

Mark, when I pull the sump off the scrap engine for Moogling next week  I will take the crank out (it will make it easier for me to move, I will get the trust washers and bring them to the rally, if they fit, use them if not bin them

I'm not sure if they are that critical. It's just my feeling that the crank shouldn't have any perceptible fore/aft movement.

Craig - not sure, but it looks like pretty standard thrust washers go in the gaps. They were AWOL when Edryd got me the engine.

Thanks Peter - please do that and I'll see what can fit - even if we just fettle something to fill the gap.

We are getting there!

Calling all Series 2 engine specialists...

Just to confirm
Early 2.25 Litre engines (Series 2).
Am I correct in understanding that on those engines (with the two piece rocker shafts), there were no washers between the springs and the rockers as per later engines? The parts book suggests this is the case and there are none in the box of bits, so assume as such.

Thanking you all muchly

[diffwhine]

Work might stall for a short while due to family issues, but we've started painting and progress has been made this morning. Happy with the colour. Some touching in required and we've missed the odd bit, but we will get to it.

Another bit of help or suggestion required...

As you can see, there is no cam follower in number 7 valve, so the rocker isn't doing anything. I have an idea...
Why not track down another follower assembly and push rod. If I very carefully tack the guide into the bore, we could have a working tappet assembly there. If I were to cut a groove down one side of the guide and clean it up well, it should be possible to be able to see into the tappet and roller as it goes up and down.

Therefore... Anybody got two or three complete tappet, roller & guide assemblies I can play about with and guides to chop up? I'll also need one push rod.

If anybody can help, please let me know. Alternatively, if anybody has the above and wants to experiment for me, that would be a great help. I'm thinking of a groove cut down the side of the guide offset to the right hand side so people can see a tappet and roller working.

[JonB]

DW, I haven't got any bits, but you're correct about the rockers. The stand pieces are different for the middle and the ends so the washers aren't required.

Thanks Jon,
That confirms it - I just wanted to make sure. Now cleaning up threads and working out what else is missing.

To add to my want list:

3 x 3 1/4" x 5/16" front cover bolts 256031
3 x 2" x 5/16" front cover bolts 256226
2 X 2 3/4" x 5/16" rocker shaft shaft special bolts 525500

Dug out a copper head gasket and cut it to fit. It was a new one, so hopefully no asbestos. Nevertheless normal precautions taken.You cannot view this attachment.

Then had a check to see how well things fitted. Definitely feels like progress.

The best head gasket I'm reliably informed is a Payen gasket. This is what I'll be using on my MG.

[diffwhine]

Yes - absolutely correct - a composite gasket is the way to go for a real build. In this case, in 1961, it would have had a copper gasket - hence me digging out one of my new ones put aside for just this sort of purpose.

[JonB]

DW, I've got a full set of timing cover and water pump bolts here for you. I don't believe the early heads used the special bolt with the deep head on the rocker pillars, but just standard 5/16 x 2 bolts 226259.

The club site has a '59 parts book to download, as it's S2 only you can pick up a lot of small changes to the part numbers compared to the '61 and '68 books

[JonB]

I've got the rocker cover 'caps' as well to go with those lovely acorn nuts 😇

[diffwhine]

That's great news Jon. So this one has the wrong rocker shaft bolts then.

Are the early type still available? I suppose in reality, I only need 2 or possibly 3 as the other two won't be visible through the cutaways in the rocker cover.
