The engine was so dirty, I wanted to have a good clean up and maybe trace some of the oil leaks!

I started stripping the tinware which i painted 17 years ago with hammerite.

Image356 by karlhash, on Flickr

Image356 by karlhash, on Flickr

It was coming off with just a scraper .

I did resort to using a small whizzy wheel off the compressor.

Image356 by karlhash, on Flickr

The rubber mount edges were a bit bumpy so straightened those up.

But these are still in bare metal and are starting to rust now that I havent painted them yet!

On taking apart the engine for cleaning I found one of the generator stand bolt holes had stripped a thread.

Image20210316_163635 by karlhash, on Flickr

My ali oil cooler was a bit dirty but didnt take too long to clean.

I had purchased a full flow oil filter from precision matters and needed to fit this also so the third piece was going to come off.

Took the third piece off the crankcases, distributor gear out but then measured the vertical free play of this part with distributor re installed.
It had plenty so ordered some shims and now the result is within spec.

Image20210327_163821 by karlhash, on Flickr

Purchased a nice carbide burr and set to carving out a semi circle in the oil passage for the full flow oil filter.

Image356 engine by karlhash, on Flickr

Image356 engine by karlhash, on Flickr

Image356 engine by karlhash, on Flickr

this all went fine but even with a large enough semi circle in the upper part I still couldnt push my tube down the hole " oh err missus"
So I had to gently massage the oil way until it allowed full insertion!

Inserted tube

Then I tried the cover on with the oil pump gears bolted lightly without a gasket and I was able to turn them freely.

then I fixed the stripped thread with a helicoil type thread

Into the heads next

Already from reading up profusely about these little engines I can see a problem with the rocker adjustment

Image356 engine by karlhash, on Flickr

With too much thread showing out the top of the rocker arm, then the oiling hole to the rocker shaft may not be lined up.
So off with the rockers and

Galling, a new word to me in engineering terms, in the rockers and the shafts.

Image20210402_153444 by karlhash, on Flickr

Image20210402_123549 by karlhash, on Flickr

I guess those oil ways weren't letting enough oil in there. New ones needed then........this feels like a budget bigger than I have is on the horizon.

Heads off
Image356 engine by karlhash, on Flickr

This will be where one of the oil leaks will be coming from

Image356 engine by karlhash, on Flickr

a bit of cleaning

Image20210403_174258 by karlhash, on Flickr

valves out

Image356 engine by karlhash, on Flickr

Surprised these sealed as well as they did.

As soon as that engine hit the stand ‘to look for oil leaks’ it was going to escalate!

I’ve a sneaky feeling that valve (and it’s matching seat) may just possibly be past their best :)

Escalate Gary, feels more like a rocket ship and Im holding on for dear life :lol: :lol: :lol:

With the heads off I could see that one of the head nuts had two washers under it instead of just the one.......

Image356 engine by karlhash, on Flickr

Inside the first barrel I took a look at and the internal wall looks poor.

Image20210414_192258 by karlhash, on Flickr

So thats new P&C s on the list then might as well go up to 1720 while I am at it .

Bath time for the heads

Heads look like they have been worked on before

The bearing in the third piece didn't look particularly healthy

Image356 engine by karlhash, on Flickr

which didn't bode well for the rest of them. so I bought a torque meister tool to take the flywheel off so that I could look at the rest of the bearinngs.

Ground the edge off first so it would fit into the flywheel and onto the gland nut more.

Image356 engine by karlhash, on Flickr

Flywheel off

Image356 engine by karlhash, on Flickr

and cleaned with a wire brush

Image356 engine by karlhash, on Flickr

But the teeth edges dont look so great. Im not sure if I can just redress these to help?

Image356 engine by karlhash, on Flickr

Oh yeah, I just cut down some old copper pipe to make some barrel holders, probably got the idea from someone elses thread years ago.

I must say that having all this information on line these days doesn't half make a difference to having a more well informed go at this yourself.
And every one elses threads on here and the other forums around the world are a great inspiration. Andrew Slaters has encouraged me to sort out the engine in particularly.
Not only are they fascinating to read but incredibly helpful as we all know.
Sorry gushing over now.

Apart from the valve not sealing those heads look ok?

Ps I have one of those torque tools. Pls give me a shout if you need any other tools as you are welcome to borrow anything.

Cheers Neil, you have already been of great help.
I bought the torque meister because I know I'm going to need it for a few more jobs.
The heads do seem ok, but i'm sure there's room for improvement as my school reports always used to say.

With the flywheel removed I took the case bolts out and then cleaned them.
I have been adopting this process of removal and immediate clean because I know I won't want to do it later.

Clean nuts

Case split

Image356 engine by karlhash, on Flickr

Bearings could do with being replaced. Not down to the copper colour at least.

Image356 engine by karlhash, on Flickr

Oh yes, forgot to say all the bevelled washers for the case which should have an o ring were absent so I'm surprised the engine didn't spout oil out like a colander.

This thread is great. I appreciate your pictures and commentary, especially the engine work. I have to tackle my engine at some point (long way off yet) as I only had it running pretty poorly over 25 years ago.

To be honest, I've never tackled the inner workings of engines, as the micro mm tolerances of this stuff scares the hell out of me. I'm sure I'll learn.
