Thread: LT230 PTO Endurance limit?

Good question........

I tell the lads that I can winch all day......

Maybe leave the CDL engaged and jack one wheel up.......

So your not so worried about the car running with a constant low load.....no that I have much input on glazing etc

I'd be concerned about running the engine at idle/low revs for 8 hours at a time, good wat to stuff the rings and glaze the bores, would be better off with a small engine powered hydraulic pump, Regards Frank.
BTW why do you need firewood in Darwin?

This would be my concern to. I see truck mounted/run EWP's in at work that do limited km's but lots of low load PTO hours. By 100k they are starting to get smokey at idle.


You mite also want to see what the max torque rating for the PTO is and how it compares with the input HP required by the pump. From fuzzy memory the pto's fitted to 75 series Landcruisers were only good for a intermintant 12HP.

Thanks for your reply weeds,

I'm certain your method won't work. I need to move the rig after every cut tree so the jacking of a wheel could be painful, and not inline with my goal.

Thankyou again. Cheers Adam.

not to mention it would wear out your centre diff and axle diff. I wouldn't be concerned about the t-case. Just run a good oil and install a hand throttle.

RE: firewood in Darwin, I'm buying land in QLD.

I too am concerned about glazing I hope to combat it by;
- Doing "burnouts" within a defined time period,
- designing hydraulic system to work at 2000RPM,
- 2 seperate hydraulic systems and a theoretical combine load of (I calculated) 48.3kw

Cheers, Adam

Thanks for your comment. The systems I am looking at will be based upon firstfours systems. 2 complete seperate systems. 1 PTO driven. 1 crank driven.

A hand throttle is necessary. I have looked at aftermarket belt-driven governors also.

Good oil is an absolute necessity and I expect to also adapt a centrifuge I have in the shed to combat carbon in the oil.

Cheers, Adam.
