Bob, that's exactly the point! I love it that my friends
haven't a clue what it is and somehow some way I will
resurrect this Hummer. Again thank you all for the help!

The thing I get the biggest kick out of is you're not just
messing with a motor....you're messing with history and
trying to get it running again :-)

Thank you gentlemen. I realized the need for the manual
once I persuaded the left cover off and found the bearing,
and not a seal. I really appreciate the advice, and I found
the harleyhummer.com parts site so I know where to find the
seals. I have a Harley store here in my town of Livermore
in Nocal so will set about ordering up a manual. Again,
thanks for the advice and tips!

I agree with Dave on the manual. The 58 the earliest in the
Harley book Dave mentioned is essentially the same engine as
the 56 you're working on.

You may be able to coax the left outer bearing out, then the
retainer and seal. I replaced the bearings but was only able
to find sealed bearings. I removed the both seals on the
inner and right bearings, I trust the engine lubing more
than the lube in a sealed bearing. and I removed one of the
seals on the left outer bearing, the clutch-transmission oil
lubes it pretty well.

The engine oil runs down in the tube between the crankcase
and the cylinder. A small reservoir feeds oil to the case
side of the bearing. putting the bearings in with one seal
still intact reduces air-fuel-oil from puffing through the
bearing.

Evan,

If you are disassembling your engine, you really need to
have a Service Manual. Good News! It is still available
from your local Harley-Davidson dealer.

1958-1966 American-Made Lightweight

Part# 99444-93 - Reprints of original service manuals and
parts catalogs for the Hummer 125, ST165 Super 10, Pacer,
Scat, Ranger, Bobcat and Topper scooter. Also lists the
colors, accessories and equipment for each year and model
from 1958 to 1966. MSRP US $40.00

Check the first listing under our "Parts" section for all
the antique literature still available. H-D's website has
changed, and they don't show the list of all the different
books anymore. But you can type the part number into Search
on their web site, and it will show it.

My questions is, the left crank seal is I assume behind the
bearing? Does this mean the cases must be split to replace
the crankshaft seals? Was hoping the service manual links
on this website would work but they appear to be just
pictures. I would appreciate any tips and/or advice. thank
you!!
