kv6 timing belt

[Lee69]

Belts are successfully fitting worst one I have ever done cant think why they didn't fit all four cam pulleys on the same side I think fitting 3 separate belts is much more time consuming, just got to all the engine parts back on now that have to be removed

Does the 180 need the same tool? I recall posting a question some months back about the differences between the 180 and the 190 and the response was that they are the same engine.

I am asking the answer on behalf of someone on the local Australian google group who has a 180 and is trying to work out his options.

I shall be attempting a water pump change (therefore also a cambelt change) over the Easter break on my 2.0 kv6. This is without tools.
The comment above about having all belts on the same belt, that would be a nightmare to get all cogs lined up, at least with the belts where they are, there are only 3 cogs to line up on the front and 2 (each side) on the back.

Going by expoerience on other engines, the tools hold the cogs in the correct position. As long as all cogs are marked with a blob of paint (or equivalent) then there is no need to hold them in place, as long as they are held in place while the actual belt is put on, this can be done with a spanner on the central nut.
Of course the crackshaft MUST be locked using the pin.

If I'm talking gibberish there will be a part disassembled Rover 75 tourer for sale next week.....

Yes the ZT / ZT-T 180 KV6 is the same as the 190 and needs to be timed as a 190 would be!

No this is wrong, it's only the 190 that has different cam timings, the 180 is timed the same as the Rover 2.5


IGNORE THIS, I WAS WRONG!

So you disagree with what has been said in this thread?

I read the other post with great interest, I am about to change the belts on my 190 and I've been searching for tools for about three weeks now.
I've spent every night looking at spec, and tools, and all I've found in the way of tools are that there are two versions. One for the 2.5V6 and one for the 190. The tools are all stamped up as well. But no mention of the 180.
The question is, what camp is the 180 in? I think I'll need another three weeks looking to answer that one! First, there is the comparison in the cam profiles and someone on that other thread mentioned above has said that the part numbers on both the 180 and the 190 were the same. If that is true, then it may be quite possible to time the two engines using the 190 tools.
It would be quite interesting to get it on a dino and compare them in both settings. A bit intensive though!
I think I'll keep digging and report back.....but don't hold your breath!!lol

Its worth noting though, that if you are going to change your belts without using tools, you will be assuming that the guy before you will have got it right when he did it and that there were no complications like a tooth jump or loss of position by undoing the front sprockets. You make your marks with the tipex, put it all back on with the tipex previously marked and what you have is what you started with. When you do it, (check the marks are lined up on the rear sprockets). All this while in the safe pos.
Worth a thought I think.
On my unit, I can't be sure that the guy did it correctly so I have tools.

Phil,

I will let you disagree with Brian then!
See below.

Tom.


Never said the autobox wasn't capable of handling the power Dave, it was simply detuned as the gearchanges were deemed to be too harsh.
And just because the published performance figures from a 180 are the same as a 177, doesn't mean they are the same engine.

If truth be known, here are two cars four years apart in registration, both fitted with their original engines.
There are three factory timing tools for the KV6, a set for 2.0, a set for 2.5, and a set marked 180/190 ONLY

So I have stripped a 2004 180 engine, rebuilt the heads and refitted with new belts W/P tensioners etc, an engine that was subsequently fitted to a 2001 190 that had suffered front timing belt failure.
I have the 190 heads from the original car stripped ready for rebuild, and I can assure you the casting numbers, and cam profiles are identical to that of the 180.

Now I have just examined the tune assemblies of the 190, 180, and 177 for comparison purposes, the 190 and 180 tunes differ by about 240 bytes
mostly the tune assembly numbers, and Jatco instruction set.
The 180 and 177 tunes have similar instruction sets for Jatco, but the actual tune assembly is more akin to the 190, but absolutely nothing like the 177.

So when I say the 180 ZT is not a 177 Rover, that is fact, not fiction, not hearsay, not mythology etc.

The 190 and 180 engines are identical, and not a Rover 2.5.....
