I'm the bloke in Australia who "went to bat" for the Zeus
gears when they were attacked on the forum.
I know well the site that Pantellis refers to,and all I can say is
that all is not what it appears. I've defended the gears in the forums
and also in the legal system and in both cases am happy with the
My own Disco had gears fitted at 103000km and they're going fine at
216,000 km. If you visit our website
you will see that dyno data on the improvement in performance (about
27%, and fuel improvement is around 12%).
In real terms all this means I get about 120 kms extra per tank, and
can use my engine from 1100rpm upwards. On the timing belt you need to
wait for the turbo which comes in at 1850 rpm.
About 3 yrs ago I worked out that within 75000 kms a person with gears
saves money compared to someone on timing belt when its changed every
50000kms. Given the recent 35 % increase in diesel prices the period
I have both a disco and defender with the gears fitted, and wouldn't
want to even think of driving a 300 with the rubber timing belt.
Yes there is a bit more noise at idle, but this is from the injector
pump lifters. Yes there is an improvement in economy and better
performance as the engine can now be used from 1100 rpm, which makes
towing, around town driving in traffic , off road driving all much
If you have an automatic then the improvement is very noticeable on
cold mornings when the engine is cold.
As I have stated frequently in the public domain, I'm a real user and
believer in the Zeus timing gears. I've thoroughly researched all the
"stories" and "expert opinions" and nothing has caused me to change my
opinion on the gears, nor seen any reason to stop selling them or
remove them from my own vehicles or those of many of my friends.
I would suggest you ring Graham at Zeus and speak to him directly
about the gears. Ask him the longest mileage on a set of gears that he
has seen ( about 250,000 miles).
