Just started to rebuild the AC CLB engine in my Aceca and hoping to tap into the knowledge of those who have been there before me. Does anyone know who best to contact or start the search for +10 piston rings for Wellworthy HC pistons and con rod big end shells? Many thanks for any advice to help get this AC engine back to health

AC Weller Engine / Engine block code

« on: April 13, 2016, 18:09:51 »

I have read information about the development of these engines from UMB though CL and CLB until the latest of the engines carrying CLBN. My question is, my Aceca engine also has a "W" suffix and 9/1. My assumption is that the 9/1 relates to the engines compression ratio would this sound correct or plausible? And any ideas what "W" indicates? Many thanks for any information and help

General Forum / West Midlands Section of the late 50's

« on: April 08, 2016, 16:52:45 »

While reading an AC Bulletin of Autumn 1956 it makes reference to the West Midlands Section and a spring meet of Sunday May 6th as well as Lowsonford, September 23rd. It talks about the "usual hard core enthusiasts turned up, Dr Humpreys, Wiggin, Sanders, Ridout and Brookes" at the September meet "the usual Midland contingent of Dr Humphreys, Wiggin, Ridout, Brookes and Moorehouse"
   
   It would seam the Midlands had a strong and thriving group of AC owners turning out regularly to spend a "very pleasant afternoon in Warwikshire" all that said later Bulletins, that I only have a few, make no reference again to this group.
   
   Does anyone know or remember this group and know of any other events they took part in or even have photographs of them in 1956 or later? My particular interest is in "Dr Humphreys - with his newly acquired Aceca"
   
   Many thanks in advance for any information

Ace, Aceca & Greyhound Forum / Overdrive on AC Moss Box

« on: December 10, 2014, 09:18:28 »

Hi, I need some help, I am looking to convert my AC engine Aceca to run an Overdrive gearbox. From my research this was a factory option on the AC engine cars, again from what I understand the Moss box is suitable to accept an A Type overdrive using an adaptor plate. Firstly would this have been the factory fit overdrive (Laycock A Type)? I ask as from looking at A Types they are bulky and would require the widest point of the tunnel to be increased in length considerably as well as the moving of the cross member back. This just seams a lot of modification for something on a factory options list even on a hand built car. Or was overdrive only fitted using the AC Lightweight gearbox?
   Any information or pictures of an AC gearbox with overdrive would help me greatly to understand how this was done and confirm I am heading down the correct path. Many thanks David

Ace, Aceca & Greyhound Forum / Fitting Harnesses to an Aceca

« on: August 06, 2014, 16:37:24 »

I am looking at fitting harnesses to my Aceca and having spent several hours looking at all the possible options of suitable points for in particular mounting the shoulder straps, I thought I would see what suggestions and advice come from those that have done it prior. The thing I want to try and maintain is the usable boot space. Any pictures of how you may have fitted brackets/plates would be of great assistance. Many thanks

AC Weller Engine / Rocker cover breather

« on: June 18, 2013, 23:30:42 »

I am currently working on restoring my Aceca with AC engine and have seen a couple of engine bay images on the internet showing a breather tube and tank fitted to the forward round vent on the top of the rocker cover. Is this a recognised mod for these engines? Or a solution for a problem with the engine building too much pressure and the fumes getting into the cockpit? My engine also seems to build a bit of pressure so want to understand if this is normal and then I will carry out the same mod. If it is not normal I will start looking for a problem with the engine causing the pressure.
