25. Refill transmission w i t h lubricant.
S e r i e s 37-90
The procedure for assembling the transmission
is, with the following exceptions, the reverse order
of disassembly.
1. R e v o l v e the mainshaft assembly when rais-
ing the countershaft into position to make sure
the gears mesh smoothly.
2. M o v e the mainshaft gears into their various
positions to make sure the gears mesh properly
in each position.
3. Place adjusting quadrants in the middle
position of their travel. See Plate 52, F i g . 6.
4. P u t gears i n neutral position when replacing
shifter shaft yokes and cover.
5. Refill transmission w i t h lubricant.
14. R e f a c i n g F l y w h e e l H o u s i n g — S e r i e s 37-90
1. R e m o v e all spark plugs, radiator grille and
front bumper.
2. D r i l l a hole 2 inches i n diameter i n the splash
shield j u s t below the radiator core so that the
crank for turning the refacing tool can be inserted
in the crankshaft.
3. Remove the floor and toe boards.
4. Remove the transmission as explained in
N o t e 10, Page 125.
5. R e m o v e all transmission studs i n flywheel
housing and take out pilot studs.
6. R e m o v e flywheel retaining nuts and clutch
connection bearing retainer. P u t adaptor plate
in position, using four flywheel nuts to hold it in
place.
7. Install refacing fixture. T h e mounting
holes in this fixture are elongated to permit the
fixture to be located so that the cutter bar will
have the proper t r a v e l to clean u p the entire face
of the housing when the tool is i n the hole nearest
the fixture. B e sure the nuts holding this fixture
in place are drawn up tight.
8. Install two handles opposite clutch studs
in flywheel.
9. Check face of housing by means of tool in
cutter bar to find lowest point, a n d set tool so
that it will just clean up surface at this point.
10. T h e cut should be started at outer edge
of starting motor boss on flywheel housing. F e e d
tool in about one-eighth t u r n of h a n d wheel for
every revolution of crankshaft.
11. W h e n the cut has been carried i n to a point
where tool touches transmission pilot flange on
flywheel housing, flange should be checked care-
fully for concentricity w i t h crankshaft. If there
are any low spots, they will usually be found at
upper part of this flange. S u c h a condition c a n
be corrected by peening out edge of flange with a
hammer.
Note: Care must be taken in performing this
operation to prevent breaking or crack-
ing the flange. It should not be necessary
to raise the flange at this point more than
a few thousandths of an inch and it is
not necessary that a full bearing be
obtained. A bearing of one-half the
depth of the flange is sufficient to hold
the transmission case in proper alignment.
12. After peening out low spots, t u r n flange
down to proper diameter, using gauge furnished
for checking this point. It is advisable to inspect
gauge before each operation to make sure that it
has not been damaged by rough handling. T h e
distance between the gauge points should be
exactly 1 4 ¾ in.
Caution: Be careful not to take off too much metal
when turning down the pilot flange. If
this should occur, it will be necessary to
peen out the flange all the way around
and then turn it down again to exact
gauge size.
15. S p e e d o m e t e r C a b l e I n s t a l l a t i o n
W h e n reinstalling the flexible speedometer cable
used o n a l l 37-seri«s cars, the lower end of the
cable must be properly inserted i n the transmis-
sion or the upper end will protrude enough to
put excessive pressure on the speedometer worm,
causing binding, noise, and eventually early
failure of the flexible cable.
T o install the speedometer cable properly, the
lower end of the cable must be installed first,
after which the upper cable end should extend
Jf" to f f " beyond the end of the ferrule as shown
in the illustration, F i g . 29. I f the upper cable end
extends beyond f#"> x 1 1 means that the lower
cable end is n o t inserted far enough and trouble
will result if the condition is not corrected.
