Hi Jim,
Although my experience was with a BN2, the dimensions & problems are all
similar. I too, questioned Their method. They assured me that the metal
strainer would just flatten out against the bottom of the sump if it was
"squished" sufficiently. Such a "crude method was out of the question
for me.
I shortened the pickup pipe by the prescribed amount & to original
contour, removed the strainer by breaking the spot welds, cut 1/4" off
the strainer, spot braised the strainer back to it's upper & lower flanges.
If you don't shorten the rear drain tube it will foul the horizontal
rear pan baffle. I couldn't see any real use for the horizontal rear
baffle, so just left it out. Didn't shorten the tube. I think the
horizontal baffles are intended to function as a "windage tray", but in
my opinion, they are too far from the crankshaft to accomplish very
much. The shortened tube dumping onto the top of the baffle seems silly
anyway.
The sump is a real "handfull" to get back into place & the bolts
started. Proceed very carefully & make sure that everything, clears, &
fits. On mine, they did not supply all of the new bolts which were
required & I had to reuse a few of the old ones.
I have never gotten anything from DW that didn't require rework before
it fit, with the exception of an aluminum cylinder head. The final
result is always good, just not as easy as they let on. The sump holds
about a quart less than the standard one. Go by the original dipstick marks.
Good luck,
Dave Russell
