Old Technical Sheets

Post by allan horsfall »

Gentlemen,

I seem to recall that there used to be a number of old 'build articles' on the forum with some really usefull data. In particular I am currently trying to find one that comprehensively covered the fitting of 289 rocker covers on to a Rover block, ie the carb spacer size, the breather arrangement required, spacing of the accelerator mechanism etc. Does anybody know what has happened to them please, or where I can find them???

In the members area Allan.
When you log on the forum and go back to the home page, there's additional menu options.

Hi Stu,
I've looked there already, no sign. The stuff I'm after used to be on the old forum I think, and was accessed from the face page ?

Hi Allan,
It was there the other week as I was having a read of Roger's IRS build up.
Maybe a mail to Andy Mulheirn?

Hi Allan,
I did write an article on the fitting of Ford rocker covers to a Rover but can’t locate just now.
What I can say is that I used a 0.5” Ali spacer followed by approx 0.25” of thin Ali spacers with gaskets to provide a thermal boundary for the Weber/ Carter Carb on an Eldebrook low raise manifold.
The conversion pieces for the Ford covers to Rover heads I bought from Gerry as I couldn’t locate anyone to laser cut them for me at the time.
I did have to file one of the fins on the drivers side cover to miss the carb linkage as it fowled by about 1.5 mm.
Throttle wise I have a cable all the way to the carb so it wasn’t an issue to alter the height of the carb.
The breather system used a fair bit of the old Rover tubes but basically had a tube from drivers side cover to join with another from the underside of the air filter and then onto the cap on the near side cover.
I’ll see if I can locate more details.

Hi all -

Those 'members area' items are now all within the new members database. Log in to www.the289register.com/amember/login and you will find them off the top menu: click Members Content then Technical Articles.

Cheers,
Andy

Thanks Peter,
Do I assume the spacers under the carb are in addition to the alloy leveling spacer.

My main spacer is 12 thk and is as far as I can see parallel not tapered.
The extra shims (total 6 thk) as per my article are insulating type being a mixture of gaskets and 1.5 thk Ali.
There are no other spacers or packers involved.
I didn’t see the need for a tapered spacer as the engine didn’t appear to be that far out of level.
I have just put a spirit level on my rocker cover and estimate that you would only need about 1mm to make the carb flat. I think the roads go up and down enough not to worry.
