There is no sn on the rear axle.. only date codes.

the sn is lightly hand stamped on the engine block, left side, just aft of 
the oil filter housing, just below the head, on a 1x4 flattened boss.  ALL 
9n and 2n serial numbers start with 9N

As mentioned.. if it is a 47.. it is a 2n

How did you date it without the sn?

I'd pull the side cover on the right side with the dipstick in it.. and 
operate the lift with a load on it, and see if there is oil coming from the 
hyd cyl mouth, or spraying out anywhere.. like from under the cyl, or fromt 
he right front corner ( hyd stand pipe _).. or if there is oil spraying from 
side covers on the pump or it's casting.. or any swirrling under the 
fork/valve where the relief valve is.

Could be anything from a sticky control valve.. to a leaky relief valve.. to 
a completely worn out pump.. blown gasket, or bad rings on the hyd cyl.. 
etc.

Post back with more details or for more info.  Total time to disassemble 
linkage, remove seat, pull lift cover, pull pto shaft, drain sump, drop 
pump, reseal/gasket parts, clean sump/pump add new parts, and button back 
together and drive outta the garage is about 9 hours... involves no rocket 
science.. and only uses about 2 wrenches or sockets, a gasket scraper, and a 
torque wrench.

The control fork needs to be spread and removed fromt he valve -BEFORE- you 
pull the top cover... if it has not come off already from sticking.

I did my 8n hyds section about a year ago.. very similar setup.. cost me 
about 100$ in parts and i added a naa piston .. but kept my old hyd cyl.. if 
you change out the cyl.. bump that to about 200$.. assuming no 'hard' parts 
inthe pump are broke.

Parts can be picked up new from www.ytmag.com .. somenew and used from 
www.just8ns.com and used from john smith at   www.8nford.com   ( he 
sometimes has complete lift covers and pumps..  )  I've bought parts from 
all f these places with absolutely very few issues.

I would suggest you get an I&T fo-4 manual before you attempt this.
