We have a D6D LGP with a 56 Cat winch...Pulled two teeth from the last two gears on the left side of the unit...It is stated as a slow drive in the service manual...If any gears need replaced, 'order new parts and delete one shaft w/gear set...It has two jack shafts with gears now, will only have one jackshaft when its back together.
I counted the gears, and figured gear reduction from 1000 rpm at the PTO for sake of simplicity...at 1000 PTO the two jack shaft winch turns the drum at 11 rpm...slow...with the conversion the drum will turn at 25 rpm, more than twice as fast.
With a torque converter will the faster winch have a better-longer-more reliable in a hard pull service factor than the slower winch had?..Not much I can do about it keeping the Cat winch...We can still get Hyster reman winch for $9500.00...it is going to cost $3700.00 to repair ours-cheapest winch repair I have ever had.
But, we still have a 17A that we have had since 1976 that we have never been inside the winch on it...its a Hyster D7D direct shift where the D6 is a power shift with three oil lubed clutches or brakes if you want to get technical.
Does the Cat winch have a better service record after the changeover?
Is the Hyster winch W6E better-stronger than the Cat 56 37U?
Thanks for all responces.
we are using these machines in the oil field...pulling in equipment on mud boats is what is so very hard on the winches.
