Regulator valve piston in valve body sticking

Guys:

We are having a reocurring issue that needs resolved! The valve regulator piston is hanging up in the valve body that is causing a pump pressure "spike". This "spike" in pressure is blowing out the forward gear clutch pack and wiping out the gear, clutch drum and the snap ring in the groove of the drum. The following part numbers are involved in this issue: Valve regulator#: 32737236071. 6 series transmission s/n: 920698. Transmission model#: 32050U2131-71. Lift Truck model#: 6FGCU25. S/N of unit: 78789. This issue happens on 1999 lifts. Unfortunately, our local dealer has been reluctant to assist on this issue and we are eager to learn how we can rectify this problem. Your input us greatly appreciated!

Thanks,

Jeff Starkey

Fact of the week
The origin of "love" as the score zero in tennis is debated, but two main theories prevail. One suggests it's derived from the French word "l'oeuf" (egg) which resembles the shape of the number zero. The other proposes it's related to the Dutch word "lof" meaning "honour" as players might be playing for honour when scoreless.
