Oops, forgot your traveler is probably right hand drive...
sitting in the front seat, the a/c is on the right side and the power steering is on the left. (my t/a does not have a/c).
They are driven by separate belts -- though the power steering shares a belt with the emissons air pump if the vehicle has one.
61" is the length of the belt(s) that drive the altenator (crankshaft / water pump / alt) on ours.
I do not know the availablity of v-belts in oz.
I checked rock auto catalog and came up with some slightly shorter belts that May work -- if you can get them in those lengths in oz.
There is more selection in 15mm width -- which will "set up" in the pulley a little.
Goodyear part numbers
13595 59 1/2 inches
15585 58 inches
dayco part numbers
15580 58 inches
15590 59 inches
gates part number
1560 60 inches
3v600 60 inches
I do not know about oz, but "generic" belt part numbers in the us are first 2 digits are width (like 13 / 15) and next 2 / 3 digits are length of belt.
This works for any v-belt (in the us) -- the p/s belt on my t/a is 13465.
I would try a 59" belt, but this is just a guess on my part... Maybe a 60 inch belt would be "short enough"...
Or, you could measure the length using a string or a flexible tape measure -- I think using the outside rim of the pulley will be "more accurate" than measuring in the groove (compared to the lengths listed in the parts books).
