Mike Alfrey's engine data

[David Morris]

Hi there,

I have recently been reading the excellent advice from Mike Alfrey on every aspect of Javelin ( and Jupiter ) engines. His article is published on the Jowett Club website and has some super advice for anyone considering working on their engine, especially over the dark days of winter ahead of us. ( In the UK at least! ) It also explains why Jowetts were so far ahead of their time and the problems they faced in the 1940's and 50's, in a climate of severe material and cash shortages.

However, at the end of the article I believe there should be some diagrams of pullers etc. that are referenced in the text, but these just show up as black rectangles. Obviously, I have been doing something incorrect when downloading the article, but can anyone help?

Many thanks,

David

I seem to recall that there was a tool for removing cylinder liners. I made one when I worked in a heavy engineering workshop - but it was not difficult to make and anyway the liners came out easily in the event.

There were also some plates with long tubular extensions, which were used with thick rubber gaskets to stand-in for the cylinder heads when testing the inlet manifold balance pipe seals.

I made others too - for removing the rear brake drums (based on a standard (2" I think) BSP pipe coupler and blanking plug, and another to remove the coupling from the gearbox tailshaft.

I suspect there were more, but this was 20 years ago!

Dear Pat and Ian,

I believe the puller made up by Mike is for easing the heads off the head bolts and I understand fits across the rocker bolts, bearing on the centre head stud. Unfortunately, the diagrams in Mikes suoer article are not viewable.

This puller would be especially useful if the head has been undisturbed for a long time. Like you, I have made up pullers for the liners, but found they came out fairly easily anyway. As you mention, another puller that is useful is one to remove the rear flange from the gearbox.

Interesting that you mention a puller for removing the rear brake drums based on a standard 2" BSP pipe thread. Was this for the later rear axle or the early hydro-mechanical one, as they have different threads? I shall have to visit my plumbers merchant and have a look!

Many thanks for your help.

Best regards,

David

I spoke to Mike about this when is Aus. Problem is I cannot remember the result!!!! I will email him. Perhaps our Oz readers can look fopr the original article in their mag.

G'dday,

Sorry, I have not been following this topic and have to admit that my ears should have overheated to the extent that I should have done something about it.

The cylinder head puller was a scanned drawing that has dropped out of the original document. On top of that, I have had Windows XP problems, without it telling me, and my scanner has not been 'found' when double clicking on its Desktop icon. This was so frustrating that I called in my software engineer son to delve into the computer's dark and gloomy basement. To no avail!

In a moment of inspiration, I decided to re-load Windows XP - and, [i]voila[/i]! It now works.

I will E-mail the document in its entirety to Keith so that it can be re-posted.

Regards,

Mike Allfrey.
