CAM TIMING - Conventional method using DTI, etc...

Equipment required - one 0.500” minimum capacity DTI with magnetic stand, 360-degree protractor and a piece of reasonably thick gauge wire to use as a pointer. Terminology - DTI - Dial Test Indicator/dial gauge Protractor - degree wheel TDC - Top Dead Centre, when piston is at highest point in bore BTDC - Before Top Dead Centre, before piston reaches highest point in bore ATDC - After Top Dead Centre, after piston has reached highest point in bore. Rotate crank so piston one is at the bore top (TDC). Fit timing gears 'dot-to-dot'. Set up DTI with stem resting on number one piston centre with a little preload. Rotate crank backwards slightly (anti-clockwise looking at the front), then gently forwards observing the DTI, watching where the needle stops before descending. This is TDC. Repeat this procedure, stopping when the needle reaches its zenith. Zero the dial scale, and repeat until satisfied the needle shows zero on the scale.

Idler Gear - Setting End Float

A fairly crucial part of how the idler gear operates is its tolerances and running clearances. part numbers: 22A1545, 22A1546, 22A1547, 22A1548, 22A1549, DAM4822, DAM4823, DAM4824, DAM4825, GUG705563GM, AAU8424, ADU6033, CCN110, 2A3643, 22A152, 53K547, Terminology: DTI - Dial Test Indicator End float is a continual problem as folk either ignore it through ignorance or lack of accessible information on how to do it, or belief special tools are needed. Also, later factory assembled engine units (from about 1992 onwards) were built up using whatever shims and thrust washers were available, since Rover were not making regular orders for all shim/washer sizes due to the forthcoming end of production. Consequently, many units left Rover with incorrect (usually too big) clearances. The idler gear was no exception. Too tight a clearance and the idler gear will either seize solid when it gets hot, or destroy the thrust washer thrust faces in the comparably soft aluminium gearbox and t

KNOW YOUR MINI TYPE

This is to help you understand which mini you own from a spare parts point of view. Officially There were only Mk1/Mk2 and Mk3 on sales brochures but the Mk4 was introduced by Keith Dodd in 1976 to help people understand the main parts changes. From here we eventually got to MK7

Ignition - Establishing a TDC reference point

Establishing an accurate TDC reference point is of paramount importance when developing and monitoring ignition timing (and cam timing come to that). Terminology - TDC - Top Dead Centre BTDC - Before Top Dead Centre Establishing an accurate TDC reference point is of paramount importance when developing and monitoring ignition timing (and cam timing come to that). When an experienced engine builder assembles an engine - no matter whether for road or race - he will establish an accurate TDC indicator that can be used for ignition purposes. Usually contrived as a rigid pointer aligning to a corresponding mark on the crank pulley in a position easy to see with the engine installed. Unfortunately, many of us have to deal with engines that haven't had such attention to detail - so either have to make do with the standard ignition timing graduated scale if it's there or sort something else out.

Primary Gear - Setting end float

A fairly crucial part of how the primary gear operates is its tolerances and running clearances. End float is a continual problem as folk either ignore it through ignorance or lack of accessible information on how to do it, or belief special tools are needed.

Terminology: DTI - Dial Test Indicator Also, later factory assembled engine units (from about 1992 onwards) were built up using whatever thrust washers were available, since Rover were not making regular orders for all shim/washer sizes due to the forthcoming end of production. Consequently, many units left Rover with incorrect (usually too big) clearances. The primary gear was no exception. Too much end float and clutch disengagement is adversely affected, the gear floating up and down the crankshaft in unison with the clutch plate. The result is a graunching gear change since the plate isn't clearing the flywheel and pressure plate surfaces fully. Too little end float and the gear is likely to be pinched tight as it

My own Twin point by Keith Dodd 1st June 2006

Having now covered 17000 miles in my twinpoint from new it developed bad oil leaks making it a true mini. The rocker cover seals perished along with a diff output shaft seal. The leaks now rectified, Duckhams oil was used to refill the engine.

11.08.07 - Snetterton Report by Keith Calver

Having made some improvements and progress at Croft the decision now was – what to do next? The increase in toe-out on the rear, despite being a small amount, seemed to help get the car turned better. Should I add more? In my 'softly softly' approach to getting the car sorted so I don't loose my way I contemplated this for a while and decided that on the whole it would be better to go to Snetterton with the car as it finished at Croft....
