Hurth transmission problems on Perkins M-30 diesels - 2006/10/16 02:24 A friend put in a new Perkins M-30 with Hurth trans 2 years ago (34 ft sail) and has went thru 4 Hurth transmissions in 700 engine hours.
The M-30 engine is marinized and selled by Volvo as the 2030 with the same Hurth trans private labelled as Volvo`s own.
Likewise the engine is a high speed, high compression (23 to 1) 3 cyl that is subject to high torsional dynamics at lower RPMs and this creates big problems - wears our the splines on the drive plate and then chews up the clutches in the trans. One trans lasetd only 50 hours from new.
Perkins used a spring drive plate when sold as the M-30 - Volvo switched to a 2 part rubber drive plate and apparently photographically incraeded the weight of the fylwheel to immensely reduce the torsional destrucvtion - wonder how they knew and Perkins didn`t?
Aynway - the question - who knows about 2 or 3 cyl diesels with lightweight flywheels that blindly tear up the trans with torsional dynamic activity?

Hurth transmission problems on Perkins M-30 diesels - 2010/02/07 00:21 Hurths are TERRIBLE. ok, that is just my opinion. I am on my forth one in as many years!!!! first one lasted 200 hrs, second and third 100 each. on fourth at less than 20 hours and it is slipping. the only thing you can adjust is the distance the gear shifter pushes it into gear. The "factory" installation (on all four) has proved inadequate and another mechanic has told me to idle down the engine, which I have done and it still slips even though the engine is running at super low RPMS. I am at my wit's end but will keep you posted as to it's progress. please let me know if you have come up with anything in the years since you posted this.
