new to me 533 groans and almost stalls on sharp turns

[wayn1234]

well I just got this machine.older 533, it has a diesel, seems to start decent, no hour meter, at full throttle. it lifts and tips bucket with ease, also forward and reverse seem fine. but if you try to turn hard or zero turn,, it moans and groans and stalls out basically. What is the best place to start? thanks

Move up to a tree or pile of dirt, push into it. Do trhe wheels spin? or does it just bog down?
Do you get lots of smoke?

havent tried that. I actually havent paid for or picked it up yet, just a deposit, going to pick it up tonight. how quickly can I check compression, I have a tester, what tools will I need since it will be off site for me.... what kind of compression should I get (I have only ever checked on a gas engine). lets say it does have bad compression. is it still worth $2800. chassis is in pretty good shape and there aren't hardly any leaks. how expensive is it to rebuild that diesel. or is it better to re-engine it with a gas? again I have only worked internally on a gas engine before.

Compression on a diesel is usually high 400's, anything below 300 is very poor.
To check compression you need a tester that can handle the pressure, put it in a glow plug or injector hole, these can be an issue as you need adaptors. It could simply be because you were trying to turn too fast on a sticky surface, especially bitumen, this is hard to turn on.

"moans and groans" sounds more like a hydro/hydraulic pump/motor issue than the engine. In my opinion, hydro problems are WAY WORSE than a "simple" engine problem. I'd have someone you trust with lots of skid experience go with you and diagnose this before you write the check.

this could be normal. the 533 has about 25 hp ,not a lot of power, if you are trying this on clean dry asphalt with full stick travel i would expect the machine to bog or even stall. When using an oversize bucket and loading a truck with my buddies machine i stall it right off ,using a little less stick makes the turns work out fine . I have a s220 ,no power problem at all ,when i jump into his 533 i have to remember to go easy on the sticks!!

Some folks also mistakenly think the farther the sticks get pushed the more power the machine will produce. Push the sticks all the way increase speed, which reduces rim pull aka wheel torque. Is previously mention easy on the stick. Asphalt is particularly hard to turn on, just too rough, concrete is easier if its smooth and dirt is the best. As Tazza said put it up against something it can't push and it should spins the tire at 1 to 2 mph with about a 1/4 the stroke on the sticks.The groaning is proportional to the load and gets worse if the engine is run too slow or lugs down losing rpm. Under high loads a hydrostatic drive system prefers to be run at full rpm, less is ok for lighter load tasks however.
