if you are chopping brush -- there are mulchers for that job wont get those tire poking stickups with a mulcher

LoL -- you gonna have to tell us what the problem is does the gear box turn the cable or not ? -- gears strip out -- the square part wears out -- cable breaks -- tach locks up -- etc Remove the cable from the tach head and start the engine -- is the cable rotating ?

Fairly "straight" path from the head unit to the tach drive just kinda drapes along side of the engine block -- no short bends , and keep away from the manifold

Clean the filter screen - and replace the filter element fill the "can" with oil before installing Remove the suction hose and pour oil in the pump side of things -- just to give the pump a head start Remove / loosen the pump outlet hose to let air out Put the suction hose back on Crank the engine , and be ready to tighten the pump line -- or shut the engine off The old tractor is a little finicky to prime if the pump is worn but can be done

Shaft will rotate about 1/4 turn -- then you hear the brake make contact with it's anchor However -- this will not affect the calibration -- Hmm, after I said this - the shaft may need to be stopped to get the sequence to complete would be a code indicating this failure tho

Original bolts are probably "better" than any you will get now days I have never ever put new bolts in one of those engines seen a few rod bolts back out -- but none broken -- and they back out because the "mechanic" didnt tap the rod cap with a hammer as the bolts are tightened -- so the cap was "cocked" -- then loosened after the engine was running

Alternator and solenoid -- you will need to run the calibration Clear the codes and see if any new codes pop -- Turning with nothing connected = brake is bad or the clutch pack is binding/warped -- if this has been on a mower a lot -- the brake may just be burned out -- can you rotate the shaft with the engine off , more than 3/4 turn ?

Had a customer that put a 283 Chevy engine in one Also had a H or Super H setup the same way Both were in our shop a few times over the years

454 would have the metallic clutch disk -- those usually will not "stick" 2300 possible could have an organic lining on the clutch disk -- those will stick with moisture

Snap a picture of that pump -- we don't need to be guessing -- Original setup , fuel flows to the rear filter from the tank -- need to know there is good flow -- spin that filter off and prove the flow -- dont use the shutoff at this time Original setup - the second filter got fuel thru the transfer pump -- there are check valves in the transfer pump -- and in the primer housing -- fuel does not "flow" to the front filter -- it has to be pumped

Yup baler twine here What is this thing - zip tie ? definitely not a Farmer thing

True that ... the gear will bind in the front cover and break the cover turn the engine to where you intend to leave it before removing the pump @Cody IH I searched for a puller , but all I see is the 2 hole version for dodge trucks -- I suppose you could drill the other 2 holes to make it a 3 hole pattern The puller I have is from OTC and has bots sets of holes -- but easy enough just to make a puller

All of the oil is in a common reservoir on that tractor -- the oil in the Hydro is held to a higher level than the rest of the oil by way of baffle and pumps -- that is why the oil level is checked with the engine running your information is incorrect or misinterpreted

Well there is VG, HVI , and DSP that I find all called Hyspin 68 but for different applications

Naa -- hang around you are valuable to this community I have a box full of "brass" that I have collected over the years never know when one may come in handy for a project made plenty of bushings from old brass fittings

one of the Doncaster design utility tractors -- x74 - x84 - x95 - Etc

The original fitting has the check behind the orifice plate I have a couple laying around here First one I came across -- this one is intact the line fitting is there to show the large hole The update fitting has the orifice in the line fitting -- and just a plain elbow -- if the guts are already out of the original fitting -- I have re-used the elbow with the new orifice line fitting -- waste not - want not

Yes , since your tank stand pipe is missing original pump fitting had a check valve with orifice need to determine if that has been removed - or is laying in the throttle box of the pump -- if previously removed -- but not the fitting then not so much of a problem but fuel would flow back thru the gutted fitting to the front filter

Changing the oil soon also ?? that nasty oil will damage the Hydro -- if not already

Have had that also -- the rust worms got the pickup tube There is a square "oring" on the pump plunger -- and a regular oring under the plunger handle -- this one seals when the handle is snugged for storage The whole pump threads out then you unscrew the handle from the stem 1802465C1 square ring 9672467 oring

Usually the guts from the fitting get into the injection pump throttle box , and block the throttle from opening up -- I have had two that the parts got under the throttle with catastrophic results -- that is 2 out of couple hundred, so pretty rare -- if the guts are gone from the elbow fitting You remove the small cover on the side of the pump -- then remove the lock wire and 2 screws -- dont drop the spacer bushings -- pull the throttle actuator out -- and look inside for the lost guts

Bottom pic is for Pioneer couplers Top is the IH coupler -- I see one of the levers is missing ?

Yes , you can put 2 handles on that valve just take all of that linkage off handle kit from Surplus Center for Gresen valve -- or Cross should work

would be easy enough to add a stand pipe to the return fitting 5/16 steel brake line would do fine -- brass it to the fitting More concerned that the original return fitting is at the pump those liked t puke the guts Also hard hose from the filter to the pump ??

I have 5 or 6 of those tanks at the other farm -- if I get a chance can take a measurement
