Hd9

Typical aftermarket blade for the old girl, probably a dealer attachment.  If the stack has been covered and the engine will hand pull thru a bit over easily I would pull the valve cover check the racks, pull the intake stack at the blower look for mouse nests, debris, verify the emergency stop is not dropped, check for coolant in the oil and that has coolant in it.  Rails by casual glance do not look too rough, this would be a project tractor not a continuous use tractor due to age and low availability for repair parts.  Most of the shields and covers still on it, seat and battery box look to be missing but not big items.

Check the engine oil level. Remove the pan guard or access cover, carefully loosen the oil pan plug checking for water. I always try to pre-oil a motor that has been sitting. I use a porta-power with motor oil and break into the oiling system. The most accessible place is at the oil pressure gage. Check the final drives before moving it. Tow it backwards with transmission in neutral to see that both tracks are turning. Drain water out of the fuel system before trying to start it.
Good luck

Hellow gemdozer.  Are you saying the HD9 uses same engine clutch components as HD11?

thank you

then your bride can drive this one to Walmart!

HI  I check wednesday if am still have some but not sure and if you weld yours she gone recrack again.

I am sorry found anyting yet about master cluch

Hi gemdozer.   I located a good used part in Australia of all places.   They describe themselves as the biggest dismantler in the southern hemisphere.   They have a few HD11's in stock for parts.   I may have found something else in the US if I searched more yet after many hours of searching and sending out emails I found this part in Australia.  So good used back plate is coming in as airmail.

I have messaged Phil Hunt as well on some parts. You are right,, he has a huge inventory. Pretty costly to get it back to the US however. Another site that has a lot of AC inventory is

Fresno Tractor. they have a large yard but cannot find the contact number. You can google it for sure.

Thank you for all the contacts fellows.   Just received good used back plate.   I have to put flywheel back on crankshaft and  the 9/16" NF bolts (13/16" head) were very tight or just well seized from being attached for many years.  We broke them loose and thinking of using blue thread locker upon assembly.   The service manual states 95-105 ft lbs for these bolts yet that seems a little low.   My generic torque chart shows 110-180 ft lbs depending on grade.  The service manual is for the HD11 with the 6 cylinder diesel and this machine is the HD9 yet uses same clutch assembly for the Diesel 471 4 cylinder.  Mechanics wire is threaded and twisted through all flywheel to crankshaft when attached and bolts torqued.   I was wondering if gemdozer has torque specs for HD9 4 cylinder flywheel and back plate?

Ok, thank you.  No problem.
