nope that model Case has belt driven hydro pumps. I have a call in to verify horsepower to series chain that will be needed, It looks like a single, series 60 chain and sprockets will be really close . But I am gonna ask the people who deal with this stuff daily and see what they suggest.
It was good to talk to you if everything goes to plan this aint gonna be to bad. It looks like a 2 to 1 ratio will be good enough with chains and sprockets will let you know how it works in a few days.
Yes you have sent me thru skid steer forum and I joined that group but there is not much there with the skid steers of this age from what I have seen this model was first made in 1964 the end production date I have not been able to find out. What I have found out is that this hydro operated speed control pulley is a weak spot in the design. It might be easier to call me so maybe we can get on the same page my cell is 727 421 7072 I am on eastern time.
The hydro pump is run off the flywheel direct and the wheels get power from the engine crank thru a hydro operated piston that operates variable speed pulley that belts to a jackshaft. I looked at the dingo it is hydrostatic trans. or I missed the pulley system I will look again now I was kinda rushed before..
I talked to bobcat and also checked on their parts website and the parts show NLA and the parts yards that I checked do not have them parts either. the crank is 1-1/2 inches with 3/8 keyway belt is 3/4 thick and 1-3/4 wide . The original variable pulley dia. is approx. 9 inches. If you got any ideas let me know before I start modifying please.
Hello, BOB. do you have any idea what the average variable sheave type cvt pulley ratio is? reason I ask on the bobcat 500 the engine side sheave pulley half shattered the other day.(parts no longer available) when all has been going so good with it. I am thinking about making it a chain drive between the engine and the jack shaft ,fixed speed ,so I need to keep it slow for power but not painfully slow. Just trying to get it good the first time around. any thoughts?
is there a 12 volt heating tape like the 120 volt water pipe heating tape you could wrap around the 4 cylinders and layer some wrap around insulation? but with that I would think a bigger alternator would be required. maybe you should check and see if there is a synthetic hydro. oil that would meet the tractors requirements and have a thinner weight. I know that there is a 0 – something weight engine oil now.
good, you know at the least getting the batt. out of the way is gonna make cleaning the radiator much easier. Though I would think it would be better if the ground cable went to the engine block,(your highest amp draw is the starter) every joint-seem is a potential for added ground resistance.
