AACO Engine Rebuild

[Sam]

Hi Everyone,

I'm currently rebuilding an International AGD-282 engine that was fitted to my MK3 AACO, just wondering if anyone can help out with torque specs for the bottom end? (dont have a manual!)

Basically I just need to know big end bolts and mains


Cheers

Hi Sam

The head studs are 90 ft/lbs
Mains 80 ft/lbs
Big ends 50 ft/lbs

Guys,

While on the subject of Acco engines can anyone give me the normal specs for them e.g point gap etc and how the hell do you set the timimg on them?
All help much appreciated

Hi Pete

The point Gap for the Bosch Distributor is 0.012 to 0.016 thou of an inch .

Ignition timing can be checked and adjusted using either method ,

1. A power timing light attached to no 1 spark plug lead and the flashing light shone into the window of the clutch housing while the engine is idling ( slow ). The stobe light should freeze an image of a steel ball on the rotating flywheel and it should line up with a stationary pointer on the housing .
If this is not correct the distributor can be loosened and rotated to achieve the line up . Note, it may be advanced a few degrees with the use of todays fuels ie , the steel ball showing before the pointer .

2. Connect a tacho to the coil , bring engine revs up to approx 2000 r/min by adjusting the idle speed screw at the base of the carby . loosen distributor clamp bolt so as to allow distributor to be rotated by hand , rotate dist clockwise and revs will fall off , now rotate dist anti clockwise until tacho reaches its highest reading and not fall off , do this several times to establish the highest rev reading and when satisfied lock up the dist bolt and reset the idle speed , 450 r/min .

Road test to see if ping occurs at low speed , full throttle in top gear , if so retard timing until pinging disappears .
