The reserve winch was constructed using the Tost winch that had previously been fitted to a bus chassis. It was decided to dispense with the bus when it became too difficult to maintain.
Engine
When the club originally obtained this winch, it was fitted with the Oldsmobile 455 engine that is now fitted to the Skybrid winch. The 455 was removed when the crankshaft broke. It was replaced with an Oldmsobile 403, which though wasn't as powerful as the 455, proved to be a good winch engine. Unfortunately, this engine threw a con rod, and so was replaced with a Pontiac 400 (The club's winches are both fitted with GM TH400 which are available with two different bell housing patterns - Chevy style (five bolts) and BOP (Buick, Oldsmobile, Pontiac) style - 6 bolts. This means that the club tends to use Oldsmobile and Pontiac engines (we haven't tried Buicks yet!). Click on this for more data on the Pontiac 400.
Chassis
The bare chassis was designed in 2012 by James Hunniman and built by a local contractor. Suspension, wheels and tow bar were obtained from other sources. The total cost of the project was £xxxx. At the same time the gas tank was replaced and fitted with a solenoid operated gas cut off valve. The original front fibre glass moulding was replaced with a protective grill and a new engine cover manufactured. The back of the cab was reworked to permit easy access and a new seat fitted. A weather guard was fitted for the radio.
Parts Replaced/Work Done
In Sept 2012 while the winch was being re-commissioned it was discovered that the sump contained 14 litres of water as well as the usual oil content. No explanation for this could be found. The engine was drained without being run, refilled with oil and fitted with a new filter. The engine was run for a short period and the inevitably sludgy oil drained. It was refilled with a flushing mixture, run at operating temperature, drained and refilled with fresh oil and the filter changed again. After running for a while the oil was checked and found to be clean. The radiator shroud was adjusted having been found to be fouling the fan. After refitting, having been 'borrowed', the starter motor started making 'binding' sounds, even though the original shims had been refitted. Various shimmimg arrangements did not improve matters, so it was decided to go with the original shims and keep an eye on the condition of the flywheel ring gear.
The drum brakes were adjusted and the wooden cable guards realigned.
