My type 4 engine build...based on AP 1800

Right....so now that I've sorted the pushrod TUBE wire , I'll now carry on explaining what I've done. And this is where it may all go horribly wrong as one of you tells me I've completely fluffed it up and should never have done what I've done. But bear with it as I believe I've justified it, but as always I'm more than happy to be told I'm an idiot and I need to start again

So, just to recap, this is an 1800 AP crankcase out of a '75 bay being fitted into an '80 Type 25. Needless to say, as I'm getting towards the end, things are discorvered regarding compatibility issues which I've attempted to work around. First problem noted is the dipstick position relative to the engine mount carrier. This is the filler pipe with dipstickhole


And here is the type 25 engine mount carrier


Hmmm.....doesn't really fit well does it! So, after much head scratching and use of my airtools to try and relieve the carrier enough to get the dipstick in, I found the only way was to cut off the right hand section that holds the angled mount in place. Obviously I wasn't going to leave it like this, so I manufactured a plate to hold the mount in place. I made it out of steel and bolted it under neath the vertical mount to give it some strength, and relieved it to fit snuggly around the filler tube




My thought is that the other 3 are as per design, and the whole lot are bolted to the carrier bar which bolts to the chassis. There will be less strength than before between the mount and the engine, but at the moment I'm happy that there should be enough, and I will monitor it continuously during the initial phase of driving. I'm also planning on shimming the carrier bar on the right hand side where it bolts to the chassis to compensate for the angle I've introduced so the engine is back level again (if that makes sense).

So....scream at me now if I'm an idiot please

 

The fan housing also didn't sit perfectly against the four faces on the crankcase due to the carrier. So I did a little modding with a sanding wheel to relieve one or two of the fins


Once the housing fitted nicely, I fitted it and installed the fan too. I'll take more pics tonight of the installation as I had to modify the alternator bracket, fit a longer belt and then procede to cut up and grind the tinware in various places!!

 

are you not going to find it impossible to get the rubber dip stick boot on when the fan housing is attached ?

 

Won't know till it arrives but it's only 4 bolts anyway, so can quickly remove it. I needed to crack on to find any other issues too

 

Got some more done recently. Firstly put the pushrods tube wires in properly after the advice above

 

I also whipped the fan housing off and fitted the bellows I recently received

 

I've also been closing up some of the holes that I don't need in my van

 

After a lot of putting on, taking off......I managed to get the alternator mounted. Ended up drilling the fan housing and bolting through it for the main mounts


And then making a bracket for the adjuster and using an existing mount on the housing to bolt it to

 

And I had to use a longer than normal belt


But it seems to have all worked out in the end.

 

As I'm nearing the end of the build, and we had a couple of nice days, I took the opportunity to turn this



Into this


Just brushed on rustoleum which I thinned down I little so it went on easier. I'm well chuffed with the results. All I did was rub the old paint down a bit to get a key, treated the rusty bits by grinding down and applying vactan before the paint

 

Next was tinware time. I'd already cleaned and painted it all, but I knew it was going to need some fetling since this is a mix match of bits. Took a while to get the bit around the oil tube to fit but finally got it all on


I've also added some 3mm foam tape between the panels where they overlap, and taped over them too with some high heat tape. I used the same stuff to block off all unwanted holes, even those I'll unblock later when I'm ready to sort the heating out

 

I fitted the new thermostat too


And new studs for the carbs on both sides

 

To finish off, I fitted the new coil and Taylor's leads, which match the engine bay colour


You can also see the cylinder head temp sensor cable coiled up which I think is the only thing I forgot to flaming photograph!

 

So....all that's left is carbs refurbed then put it in the van. Fingers crossed that's tomorrow's job

 

Well done matey. Great thread and looking forward to the rest.

 

Have you not fitted this and fired it up yet? Do you want me and my glamorous assistant to bob over and get it running so you've got time to post

 

Great thread and love the pictures especially for those of us who have never tackled such a task!

 

Thanks

That's exactly why I've done it, because until now I had never tackled anything as big as this either. The aim is to show what I did and why, and more importantly what I've done wrong so others can avoid doing it. It is in no way supposed to be a "this is how to build an engine" thread, as I have no where near the relevant experience for that, as shown through the posts. But with the help of those who have, I've managed to get to the end. It's now installed in the van but haven't uploaded the pics yet, and fingers crossed tonight is the night I turn the key (only finished at 2130 last night, and I think I've annoyed the neighbours enough already!)

 

Don't forget to put some oil in! Leave that kind of schoolboy error to the likes of me!
