Steel Cooper S timing gears.

Postby philthehill » Thu Sep 27, 2018 9:57 pm

For sale:-

Used Cooper 'S' steel timing gears with new MG Rover duplex timing chain.

The camshaft gear Pt No: AEA696 has been lightened by reducing the web thickness, during the lightening process the forged part number AEA696 has been removed.
The crankshaft gear Pt No: AEA695 is standard and factory stamped AEA695.
The MG Rover duplex timing chain Pt No: 2H4905 is brand new and is inside a MG Rover labelled wrapping.

The gears have been used but the teeth are comparable with my little used steel Kent Cams duplex set up.

The duplex timing gears and chain have not been fitted, used or lightened by me as I have managed to purchase NOS items.

£38 plus postage.

Photos can be provided if required.

I have been asked for additional information regarding fitting the 'A' Plus timing chain tensioner with duplex timing chain assy.

The timing cover will have to be replaced with one having the bulge which will allow the fitment of the tensioner.

The timing sensor will have to be removed and the dimple underneath knocked out to clear the chain. The oil deflector ring around the oil separator access hole may also have to be removed for clearance but not always required so check clearance re this matter.
Photo of timing chain with sensor and dimple removed is below.


The front engine plate should be drilled to accommodate the head of the pad pivot pin and additional cover bolt.
Below is a MG Midget front engine plate modified to suit the 'A' Plus timing cover and chain tensioner. A plain flat 1275cc 'A' Plus engine front engine plate was used as a pattern.

The tensioner mounting bracket, the pivot pin and pad are all available from Mini Spares.

All parts can be obtained new or used from 'e' bay if required but would always use a new rubbing pad.

The tensioner pad should press firmly against the chain but excessive pad pressure will lead to rapid wear of the pad.
An alternative timing chain cover without oil separator canister can be used
