whats wrong with a zeus gear kit? Noisey yes but when fitted correctly they are a nice safe guard and fit and forget Jai
dont believe their advertising, do a bit of googling
plenty of info out there that will make you see sense regarding those kits

Well going on my own experience they seem great. My bro an ex land rover trained fitter with over 25 years experience has fitted 5 zeus kits all of which are still going strong and with many many tens of thousands of miles continue to go on. One of which was a 200tdi defender 110 that we drove to Croatia 3 times and all over europe when i was a wee lad. Another was a 90 that has been driven all over the world greece and back a couple of times. Yes I have heared the horror stories with people fitting them themselves and not having much luck after a few thousand miles. I can only in on what I have seen and witnessed and its all good to me.

you might want to read some of the numerous articles here
Rovin' the Globe
also the reports carried out by and for turner engineering
Rovin' the Globe
and i quote directly from one of them:
The teeth on these gears have a rough, ground appearance with metal pickup in the roots and these are characteristic of gears for low load applications where gear hobbing is adequate and the added expense of a ground tooth form is not justified. Such gears are usually used for relatively low speed applications. This method is not satisfactory for high speed applications due to vibrational problems or to high load applications due to fatigue problems from the relatively rough surface of the teeth, and particularly from the tooth roots. In addition the edges of the roots on these gears have been roughly ground, and this has left sharp stress concentrations in the material which could very quickly lead to fatigue of the teeth Conventional dressing of the edges of teeth is carried out by grinding in a direction of 900 to that direction used on these gears and this avoids the formation of such stress concentrations. This rough form can be seen in the root areas within Fig.3. With gear hobbing the tolerances produced from machining are usually significantly greater than those achievable by grinding. In other words the process is less accurate. The contact profile shown in the photographs accompanying this report and the presence of deformation of the corner of the teeth as shown in Fig.3 demonstrate that there are geometric inconsistencies between the mating teeth on these gears. This, in conjunction with the rough surface will produce a poor quality of mesh with accompanying vibration and gear noise plus loss of efficiency.
The vibration caused by the contacting of rough surfaces of this type will lead to vibrational effects which can change as the speed of the engine varies. All components have harmonic vibrations which can be amplified at certain frequencies when a source of vibration is to hand. The operation of these gears will therefore generate a range of vibration frequencies which can affect the other components within the vicinity. It is possible for example, when worn or poorly fitting gears operate in an engine, for various components within a vehicle to begin to vibrate in harmony at the same frequency, leading to their early failure.
The effects of these vibrations will be felt most severely by the plate holding the idler gear, since this is located onto the block by the cap screws provided. These cap screws have vibrated loose and chattered in the holes leading to wear on the threads and fatigue of two of the cap screws. The vibrations from the operation of the gear have undoubtedly been responsible for fluctuations in stress on these screws, which has led directly to fatigue cracking and failure of the locating studs causing the plate to work loose. The arc of abrasion from the drive gear appears to be due to looseness of the locating plate witch has rotated around the central fixing.
The damage to these cap screws is so severe that any evidence of Loctite or locating paste has largely been lost, but there is evidence of locating paste or Loctite on the underside of the main plate and this would seem to confirm that the components had been correctly fitted originally. Any locating paste such as Loctite Stud Lock is unlikely to be capable of withstanding severe vibrational effects and it is unlikely that this aspect of the fitting of these components is to blame for the failure of the studs and damage which has resulted.
A relatively simple chemical analysis exercise on one of the gears suggests that the gear material is to specification, but the manufacture and the quality of finish of each of the gears is far inferior to the quality described in Zeus literature, i.e. precision ground gears. The gears examined would benefit from crowning, tip relief and a significantly better finish on the tooth profiles, the tooth roots and the corners of the roots, all of which in the existing gears suffer from serious faults which may reduce the effective life as well as causing severe noise and vibrational problems.

so they are crap according to turners but all i have gone on was how long they hat lasted and they have performed faultlessly on every occasion Jai
I dont think it it just Turners who think they are of poor quality and design, and not fit for the use intended
I first became aware of the issue when i was asked to look at a 200 that had had this conversion done 3k ago, 3 teeth had broken off the main gear and thus making a very good job of distroying the engine - since then i've seen 3 others with gear failure - i've also remove the conversion on a number of others - reading the numerous reports since then has confirmed that this is a low quality conversion and is not suitable for heavy long term use - i'm sure there are people who have done a good few 100 mile in them, they'd probably be fine for 30k of light duty work but to say they are a fit and forget item is just wrong

i honestly havent seen any fail as you have, i was totally unaware of the quality issues mabe the quality has degraded since i last saw one Lag Jai
i'd hope the quality of them has gone up, it's been a good few years since i've seen a landy that's got them fitted and those reports were done a while back - Zues do still advertise them allbeit very subtly and the general popular opinion is that they are not what they could be, and thats a shame as the concept is sound

I was recommended them once too, and was amazed at the number of people who have had issues with them!
I thought the idea sounded really good, but they would need to be very high quality.
Mind you, if every one they made was crap they wouldn't still be in business i guess.

think they mainly do brake conversion parts now - apparently it's hard to get a response from them these days about the timing gears

if ya tek ya landy to a landy dealer they dun use after market parts they use genuine parts. if its good enough F them its good enough F me. av seen cheap components fail and on something like the engine timing belts ect i would rather pay more for genuine than less for cheap and end up regreting it.

Well already I'm not overly impressed! The manual pump isnt responding what so ever. I've got my tractor running again though mind. Can someone actually suggest another manufacturer of lift pumps (quality ones?) I've searched the list that Disco gave me but I can only find Bearmach that make them and they're just as bad.
Cheers

Its a britpart and its working yes but the manual prime lever (which was responsive before fitting it) isn't responsive at all. Ive tried turning the engine so that it stops on / off the cam but that makes no difference. Even if I hold the lever down with the engine running it isn't forced up or down!
