i forgot about that turkey being in the photos there curious critters
and are attracted to shiny things
that one was harassing me while i was getting some shots of the loader
it would peck at me every once in a while just for fun

im going to be working on the loader this weekend ill get some more pics

i put a new seat in it had to get a new pin for the bucket ,someone had a grade 8 bolt about half the size in there
i did some welding on the bucket it had some cracks and old repairs that needed attention
i only had one crack to weld up and ran slap out of wire on the welder

im going to get into the radiator and try and rod it out this week ,as im working nights ill work at it in the mornings

only question i have is ,
does the thermostat drop right in at the normal spot like on a car engine ?as i did not have one when i got it so i never seen how it goes in thx all

With the thermostat functioning as a diverter as well as a valve, you may get good results from simply installing the correct one before you go to the trouble of cleaning the radiator.

i may try and see how it runs .however it is an old machine i dont think it would hurt to clean it out
im guessing the guy i bought it from didnt know what the issue was
as he said it just needed a radiator hose

i think he didnt have a clue just like me and had the head reworked when
it only needed a thermostst

got all the parts in gona start on the loader in the morning

hey all
i got the new parts in it took a few mins on the injectors the thermostat went right in
i did have to make a gasket for it but was no problem

i had to barrow a torque wrench i had some anti seez

after it was all done and the fuel lines purged we fired up the old girl she purred like a kitten
we watched the temp guage for a while and watched the injectors for leaks
after about 15 mins she heated up the thermostat area was hot to the touch but everything else was barley warm
just a lil heat in the top of the radiator

i took it up the hill and did about 30 min worth of work .the temp would come up then the stat would open letting water threw
temp would drop back to normal

it was a good catch you guys helped out alot i really appreciate the input .now i can get back to what i bought this machine for
cutting fence line and digging a lil pond thx all ill be watching this forum in the future also
