Now that you realize we we're
up to no good, might as well confess we've taken a used, but
sweet running '79 Spider engine and up to a point, turned it
visually into a 1750 engine.
Should you not have accessed
this page through the 'No Longer For Sale' '69 Alfa Spider -
well, that's where it's headed. Before this discourse is over,
we'll tell you how to spot the exterior difference between Alfa
2000 and 1750 engines.
If you're wondering what
Stage 7 engine preparation is, you will soon see. However, the
mechanical work shown on the right, is not included.
Since everyone likes prices,
the Stage 7 engine prep is $500 over the cost of an engine rebuild
(excluding outside costs) or $850 (excluding outside costs) should
the engine not require rebuilding.
To help explain, the '79
engine was removed and went through several washings. This would
normally be part of the restoration process. All of the peripheral
parts of the engine (on the stand) was removed, and went through
several more cleanings.
Should a client want an engine
rebuild as part of the restoration process, all of these parts
would have been removed, cleaned (but not necessarily detailed).
Thus - $500.
Obviously our engine detailing
would be $850, plus cost of mechanical work.
Stage 1 would include having
the cam cover polished and the exhaust manifold sand blasted
and painted with 1500 degree high heat paint. We're working on
Stages 2, 3, 4, 5, and 6 specifications.
Here is what was done before
the aesthetic process began:
Remove clutch disc and plate.
Fortunately almost new and were reinstalled. Removed Spica unit
and the various inspection plates and thoroughly cleaned. Actually
it was pretty clean including the small oil filter which was
replaced. We're used to major sludge.
Lower oil pan plate was removed
for inspection and again pretty clean. Large oil pan was also
removed and both cleaned. Two rod bearings and two main bearings
were checked for clearance and found to be within specs. The
rear oil seal was replaced along with new 'cigarette' seals.
The front pulley was removed along with the front crank seal
(BR uses a special one). Side bar: The crank pulley, being from
a later engine had two pulleys - 1750's only have one. The front
pulley was machined off, the unit painted and installed. Obviously
new gaskets were used wherever required. The oil pan was installed
along with a 'fresher' buffed brass nut.
The valve clearances were
surprisingly off by a fairly large margin. Speculation was that
a skilled mechanic had worked on the engine, but was not necessarily
familiar with the Alfa engine.
The cams / valves were reclearanced
and replaced. Note dial gauge next to the spark plugs above the
cams. It was used to find an absolute TDC (Top Dead Center) and
adjust the pointer accordingly.
One mechanical problem not
resolved is the entire front of this engine needs to be removed
so that a small gear can be inserted to drive the mechanical
tachometer gears. The '79 used an electronic tachometer. One
will probably be used in the Spider.
