[AT] Yanmar

[charlie hill]

Farmer,

Find your calipers and get the inside diameter of the housing that the 
bearing race runs in.  Then get the shaft diameter and go to an industrial 
bearing supply house.  They should be able to find a suitable bearing in 
their catalog.  Hopefully there is a stock bearing that will work.

When I picked up the Yanmar this morning the seller came out quite 
embarrassed and
concerned...  He had driven it to a location near the driveway and while he 
was
driving it the steering  started acting funny. I already figured that the 
steering
needed work from when I looked at it and had allowed for that. We sat the 
finish
mower on my smaller trailer since it needs front end weight on the tractor 
and the
ones he had used had been returned to the relative he borrowed them from. I 
got the
tractor "herded" home and to the shop to check it out. It ran great going 
home and
everything mechanical but the steering works fine. I had noted that nothing 
but the
starter on the electrical system worked. The wiring all looks to be in nice 
shape
but when I looked for fuses the fuse block has what looks like small bits of 
wire to
serve as fuses??? I assume that this stuff is some sort of fusible link like 
wire? I
think I will re-fuse everything with blade fuses.

Now on to the steering problem... I stripped it down and removed the 
steering
gearbox and took it apart. The gears look fine. The problem is that the 
upper and
lower ball bearings in the gearbox are both bad. Also the upper race mounted 
at the
base of the column tube is broken. These bearings run against a round 
shoulder on
the steering shaft, one just above and one just below the gear. The gearbox 
is a re-
circulating ball unit and that part seems OK. All I found of the bearings 
was some
loose balls and a pair of really bad cages.
Does anyone accidentally have any experience with these bearings or the best 
place
to start looking for them? The seller mentioned that for what common items 
(filters,
belt, starter solenoid etc.) it had needed that he had been able to find at 
NAPA. I
wouldn't expect them to have the bearings at all. There is not enough left 
of those
cages to find a number on them if they even ever had one. I would suppose 
that
gearbox and those bearings might be used in several models???
It is a nice little tractor and generally in nice condition but I was not on 
hand
when it was built or I would have slapped somebody for making it that hard 
to get on
and off...     <(^¿^)>   Dang... those engineers must have had small feet...

There is still a dealer sticker on it from:
Tom Witvoet & Sons
12501 W. Rte. 17
Herscher, IL 60941
815-426-2308

I have not had time to check on them yet to see if they still exist. What I 
assume
is the serial # is 03944 The model is YM-1500
