Hi Captdoug. Your 103-6 is a Shibaura and was adopted by Perkins, Volvo
, Caterpillar, northern lights
and a host of other engine and machinery manufacturers.
That cover is a bit of a nuisance if it sticks and the one and only stud ( the other fasteners are all bolts) is frequently the major sticking point. Is the cover moving on the stud? If so just keep spraying it with penetrating oil
and wiggling it. It might need to be wedged off gently using pieces of aluminium flat bar to fill the gap as you move diagonally across the cover with a thin tapered wedge. Itís very important to keep the gaps even and not tilt the cover or apply too much pressure in one point...... this procedure must be done evenly and gently around the gasket
perimeter. The crankshaft pulley is off, right?
The rack clip is easy to refit
with fine needle nose pliers and as a failsafe measure run a loop/length of fishing
line through the eye of the retaining spring clip.
You can get spares for that engine from ďPARTS4ENGINESĒ in the U.K.
It helps to warm the timing cover evenly but with a paint
strip gun, not a blowtorch.
Go over the bolts again just to make sure that you got em all, especially the little group around the bottom near the crankshaft.
Why do you need to remove the timing cover? Governor problems?
