Thanks Alan.
Slight change of plan though.
By the time I paid for a freight forwarding service to ship it over to Australia via FedEx, and paid 15% extra in customs duty/taxes, a $1489US winch was going to cost me $2200AU.
There were some on ebay in Australia for $2500AU and $2595AU. I decided, after reading the winch shipping horror stories above, that it would be better to pay the extra $300AU and buy it in Australia.
Spoke to my local mechanic/winch specialist. He said he couldn't do a new M8274-50 at that good a price, as it would cost him more than $2500AU at his buy price from the local distributor. But he also said that he can build one up for me from second hand parts that he has.
Plan was originally to buy a new M8274-50, and ditch the motor to add a pair of 6HP Warn motors, or a pair of 6.8HP Bow Motor 2's, using a Flamin Fabrications Twin Motor Adapter.
So, have decided to buy a M8274 housing off of my local mechanic for $250AU, and get it sand blasted and powder coated . Then buy a Flamin Fabrications Twin Motor Adapter, and a whole lot of parts from Gigglepin, and have my local mechanic build it up for me.
Parts I intend to buy to go with the refurbished second hand housing...
1 x Flamin Fabrications Twin Motor Adapter
2 x Gigglepin/Bow Motor 2
2 x Gigglepin/Albright 12V Super Duty Solenoids
1 x Gigglepin M8274 Winch Drum (76mm wider than standard)
1 x Gigglepin M8274 Heavy Duty Mainshaft Kit
1 x Gigglepin M8274 13% Faster Gears
1 x Gigglepin M8274 Large Cam Gear
1 x Gigglepin M8274 Replacement End Plate
1 x Gigglepin M8274 Free Spool Handle
1 x Gigglepin M8274 Brake Assembly
1 x Gigglepin M8274 Brake Hardware Kit
1 x Gigglepin M8274 Brake Shoe Kit
1 x Gigglepin M8274 Seal/Service Kit
1 x Warn Lower Housing Kit
Not sure if I have missed anything that should be upgraded to refurb the winch to near new condition, and to cope with the increased power and torque of the twin motors.
Hopefully this should give me a pretty strong (and near to new) winch, to cope with my Land Cruiser Troopcarrier campervan which weighs from about 2800kg (6200lb) up to about 3200kg (7050lb) fully loaded.
It will probably end up costing about $5000AU, so twice what a standard new M8274-50 would have cost me, but will be a lot cheaper than starting with a new M8274 and throwing away half the standard parts to then add the upgraded parts.
