Leyland Worldmaster Repower options
Leyland Worldmaster Repower options
Hi all,
My 0.600 powered Leyland Royal Tiger Worldmaster is beginning to use a lot of oil and smoke under load.
As the 600 is a little underpowered and slows up on the hills I am thinking this may be a good opportunity for a repower.
I have a donor bus with what seems to be a good 680, though I am being advised a TL11 will be an easy fit and a better choice.
Any advice on the pros and cons of the 680 vs TL11?
Are there any other low budget, easy fitting options out there, Volvo, Isuzu etc?
Ultimately I would like a relatively easy and cheap repower with reliability, economy and a bit of grunt up the hills.
Looking forward to your thoughts!
Cheers,
Paul

I have no idea whether either of those are an easy fit or good choice for the Worldmaster.

Re: Leyland Worldmaster Repower options
It would be unusual for a Worldmaster to have an O600. I thought the 680 was standard in these?
The viability of repowering could well be dependant on the diff fitted.

I'm pretty sure most, if not all, Worldmasters came with the 600.boronia wrote:It would be unusual for a Worldmaster to have an O600. I thought the 680 was standard in these?

The 680 came out in the late 1960s with the Leopard (some early Leopards had 600s), and the TL11 came out in the 1980s with the Tiger.
I would say the 600 was a midmount that laid on its side, as was the 680 and the TL11.
Many have said that the TL11 is essentially a turbocharged 680.
Perhaps a 10 litre Volvo turbocharged engine might be suitable. They are normally midmounts that also lay on their side.
Please don't undertake this project on my say so ... (as they say) ... always seek advice from a professional.

All the Adelaide Worldmaster from the late fifties had the 0680 engine. It's the better option.

Re: Leyland Worldmaster Repower options
Sydney's Worldmasters were also O680s.
The Leopard engines may have been more powerful versions, as I recall reading that some WMs were fitted with 'Leopard engines" later in their lives.

Re: Leyland Worldmaster Repower options
All MTT Perth Worldmasters were specified with the 600 engine, owing to the overwhelmingly flat topography of their original operating area.

I suspect you would have to transplant the engine and autobox as a package as I have never known an OM407 h or D2566UH to be combined with a semi auto. I think the torque and power would do damage to a Wilson over time, but would sure be an interesting experiment.

Re: Leyland Worldmaster Repower options
Moore's managed to fit a GM engine in one of theirs, so a Merc engine should be doable. It is just a cost vs benefit exercise.

Re: Leyland Worldmaster Repower options
A mechanic from Koala Koaches told me 10 years ago that the TL 11s in their Leyland Tigers had worse oil leak problems than the 760 motors in their ex Adelaide AEC Swifts!shark bus wrote:.

If you have a 680 already, would look at fitting that in. It would preserve the character of your bus best as well as keeping it pure British.
I used to marvel at the performance of North & Western's Tigers with their 245hp version of the TL11. Some buses had the derated 215hp version.
But you also have to consider the diff ratio (top speed) of your bus. The N&W buses could do well over 100 km/h, so the power could be exploited in each gear, but with a diff that only allows a bus to max out at 60km/h or even less in some cases (Sydney Worldmaster), I think it would be a waste of time having such abundant power in combination with such short gearing.
An 0680 will give ample performance.

Re: Leyland Worldmaster Repower options
I have a 1960 Leyland World master and I have just put a TL11 into it. Not a cheap option. Has cost me $20,000.00 plus the price of the engine to have it installed.
Re: Leyland Worldmaster Repower options
I have a 680 for sale for $1100.00 if anyone is interested

Re: Leyland Worldmaster Repower options
Dick White bus sales Alstonville a few years back had a Leyland OPD half cab fitted with a Volvo engine if they can fit that engine into a half cab DD a Volvo engine out of a B10M might able to be shoehorned into your Worldmaster.

Re: Leyland Worldmaster Repower options
K1r1sh, would love to see and hear your Worldmaster with a TL11 in it, any chance of making a video of her please and post on here? How does it perform now and did you do anything else, like change the gearbox or diff?

Wow! How does it run?
Would you mind sharing a few details of the process, what gearbox and diff you are running and the results?
Would love to see some pics or check it out in person if you are in Sydney.

Re: Leyland Worldmaster Repower options
The long story.. Job not yet done, due to time and a myriad of choices.mrobsessed wrote:Where did you get to, sharkbus?
Option one.
It looks like the problems with my 600 are fuel system related, possibly just need to overhaul the injectors. This would hopefully reduce the smokiness and poor performance to a degree.
Option two.
I have been offered a 680 which has recently had the heads rebuilt for a good price, though I will need to find someone to freight the motor from Victoria to NSW.
Option three.
I have found a Tiger motorhome project as a TL11 donor and licencing WA will issue a permit to do the upgrade.
Problem number one is I am currently on the east coast and will have to drive back to WA for final inspection (not sure if my insurance will cover me while driving an uninspected modified bus).
Problem two is I have also been informed rebuilds on TL11 injector pumps can be over $15,000!!!!, frankly that makes me nervous.
Too many choices! ..would appreciate any input
