Parts needed for P76 into RRC

[Mister_white_keys]

Hi All,

I've picked up a P76 4.4L V8 that has come out of a RRC in the past and am planning on using this to replace the old worn out 3.5L in my 1975 2 Door.

The downside is, although the 4.4 has the inlet manifold adapter plates, I have no flywheel or engine mounts for it which as I understand are slightly different to the standard Rover items.

Would anyone please be able to tell me exactly what needs to be done to drop the 4.4 into the RRC and hook it up to the LT95 gearbox? I've heard the mounts need to be changed and the flywheel drilled but would like a bit more information on exactly what's involved.

To pre-empt all the comments I'm likely to get, I know the 4.4 has it's weaknesses and I am planning down the track to rebuild either the 4.4 or the 3.5 but I've already got an apparently running 4.4 sitting here and in the short term I'd like the car back on the road. Please don't tell me just to run out and buy a 4.6 etc. as I'm not made of money and just want to drive the old classic as it was intended, in the bush!

Thanks in advance for your help!

Cheers,
Steve

Hi Steve, since it came out of a rangie it will have the extra hole drilled/tapped in the block for the mounts which you re-use the rangie brackets.
Flywheel needs to be re-drilled to suit the 4.4 crank pattern so i would get a machine shop to do that, do you have a flexplate or something off the 4.4 to use as a guide ?

Thanks Loanrangie,

I'll check that there is an extra hole drilled, thanks for the info. I thought it was a matter of cutting and rewelding the engine mount on a slightly different angle but that makes it much easier.

Unfortunately I've got nothing like a flex plate or anything from the 4.4. Just the end of the crank with its 6 bolt holes. If I can't find an already drilled flywheel I'm happy to get one done but would probably prefer to get hold of a second flywheel so I've still got a complete 3.5 to go back in if necessary.

Cheers,
Steve

To use RRC engine mounts on a P76 engine you need to cut off the top bolt hole and extend it upwards a bit, as the block is taller. The boss exists on the block for the 3rd bolt, so if the hole isn't present it's trivial to drill and tap. Retapping to the Rover bolt size is a good idea too.

The flywheel will need the centre boring out to fit the P76 crank, then by careful measurement you can drill the P76 bolt holes between the Rover ones. A pattern can be made by pressing a circle of stiff paper against the P76 crank and transferring the marks. Accuracy of these bolt holes isn't critical so a judicious bit of filing won't measurably change the strength. Any competent engine shop should be able to bore the flywheel for you inside of 1/2 a hour.

Lastly, you'll need a spigot bush. Some of the home made bushes I've seen are terrible, I suggest you get a small adaptor sleeve machined to insert a genuine Rover one into the P76 crank. The P76 ran a ball bearing race instead of a spigot bush.

Steve, your post has been edited. Don't advertise for parts in the main forum. Put it in the Markets.

I just told the guy what i had & to PM me if intrested.

This place is really going down hill fast.....

[Mister_white_keys]

Thanks for the PM roverv8, I'll be in contact soon.

Also, thanks for the extra info bee utey, much appreciated

Sorry about the wanted ad in the forum, thought it was fitting with the content of the thread but was obviously mistaken.

Cheers,

I didn't post anything for sale....
Its like your sitting there ready to pounce on someone

When someone asks if anyone has certain parts they want to sell (wanted advert) and you said "I have xxx and xxx. PM me if interested." That's offering for sale.

I don't sit here waiting to pounce but I do read posts that look like, from their title, they will be asking people to sell them stuff.

For starters, you had deleted Mister_white_keys "wanted add" before id even seen it, but read his post & problem.

This is where this place is falling down,
Ive had this stuff sitting for about 10 yrs,because im unsure of what to do with it, read someones post who's in a bit of a pickle & responded,

Sure I stated what i had & to pm me if interested, that is not a for sale advertisement, like it or not

I thought the whole idea of a Land Rover forum was to help each other out, we pay to use this site (which I don't Have a problem with)

I've attached a pic of the spigot bush spacer that's on my p76 as well as the flywheel with the holes drilled out if that helps you at all.

p38arover, get a grip :mad::mad::mad: Talking down to people and barking at them for doing the wrong thing isn't going to keep people visiting the forum, as roverV8 said we do pay to access this forum don't we :)

Thanks for the pics Dungarover, it's good to see some piccies of what needs to be done. I've had a look at my flywheel and it looks like it's already been adapted. I'm picking up more bits tomorrow which will hopefully give me everything I need to get the 4.4L into the old girl.

Cheers,

If your flywheel has already been drilled, you probably have the modified spigot bush installed! Why don't you measure the input shaft on the gearbox and the spigot bush size and compare :)

I'm surprised that flywheel is strong enough with all those holes drilled so close together!

Me too but it seems to work. The flywheel is pretty thick so it'll handle a fair bit of punishment :twisted:
