I came across an ADO16 1275 engine and wondering if it is compatible with a mini. It has a remote change on it. will this be a direct bolt on??

some parts to cut off or replace and add.

 

depending the age of your car the gear stick hole will need modifying and you will need to sort out the bracket and mods for the rear of the remote. finally the ADO remote is different to the mini one as it has a rubber sandwich joiner rather than the Mini direct mount that turned the remote into a big engine steady. BUT some non UK made Minis used this sandwich joiner so it is not unknown. (think it was the Authi ones).

Yes and a very common swap / transplant.

 

As Nick mentioned, the Remote on a mini is also one of the engine steadies. Also as Nick mentioned, the ADO16 used the rubber sandwich plate on those, so it didn't use the Remote as an engine steady.

 

Some of the Inno Minis and the Authi Minis used the same front engine plate as the ADO16 and had the engine mounts on the radiator end of the engine in a similar way to the ADO16, while the brackets needed can be fabricated up and and welded in to the subframe, it's easier to just swap over to a Mini arrangement and fit an engine steady to the Thermostat Housing, similar to one of the DSN types.

 

The other thing to look at and consider is the gearbox itself. Many ADO16's were only a 3 Synch Gearbox and it may also have an unsuitable final drive ratio. Be sure to check the Speedo Drive Ratio too before fitting.

 

Lastly, the Outputs on the ADO16 Gearbox and for the Rubber type of Universal Joints, depending on what you have on your Mini, you may need to swap out Drive Shafts or convert the ADO box over to Pot Joints.

thanks for the all info. I currently have a standard 998 and can swap parts out. so far from what i understand the items that need to change:

 

 

- engine steady

-front engine plate

 

would it be possible to completely swap out the gear box on my current 998 and use the rod change??

[nicklouse]

Sure. You have most of the parts. You may need to get some new parts as the drop gears need to be right for the crank and the gearbox and work together.

Would it be possible to change the remote  itself to my current rod change?? without swapping the entire gearbox. thanks for all the help. want to be sure before purchasing if this will work for me

not possible.

 

but before buying anything you need to know more about what you have and what you are buying.

 

the ADO will be A series but is your 998 A or A+? what size is the drop gear idler bearing. the rod changes could have the smaller earlier or the larger later size. putting an A series on a later box is not an issue but you have to use a transfercase that matches the bearing size of the gearbox casing.

here is what I have:

 

Metro  Engine type & CC :  A+ 998 cc Transverse mounted  Fueling :    Engine features :  1st Alternative compression ratio Gearbox features :  Std. Ratio Rod Change gearbox with Pot Joints 

3.65:1 Final Drive 

 

 

 

 

here is what i want to swap it out with:

 

Source Vehicle :  ADO16  Engine type & CC :  A Series 1275 cc Transverse mounted  Fueling :    Engine features :  Exhaust emission control Gearbox features :  Std. Ratio Remote control gearbox, 4 synchro' 

3.44:1 final drive

You can fit up your gearbox from your 998, all you will need is an A+ 1275 Primary Gear.

 

I would suggest though, that you visit the Final Drive, with a ratio of 3.65, you'll find it rather short, I'd suggest swapping out to a 3.44, though, many seem to run 3.2's.

[Ethel]

3.65 seems high for a 998 Metro power unit, is it from a van? Not sure off the top of my head what they used. Mini vans & pickups had the 3.76 Nick mentions, as Metro vans started out as just converted hatchbacks I've always assumed they never got a specific ratio of their own.

 

If you're not running your Mini I'd be inclined to strip both down, or at least the replacement, the condition of what you find inside could easily be a bigger factor than the flavour.

 

Notwithstanding the above, I'd say the simplest would be to source a 1275 A+ primary too. If your A+ is also Verto that would be another minor problem to factor in to a complete swap.

im not entirely sure where it came from as it was already in the car when i purchaed it. 

 

Yes, currently have a verto. what issues will i come across when using the verto??

[knowell]

so my plan is to use my existing 998 A+ transfer case and verto clutch. done some research and hoping I’ve gathered all the parts ill need to mate it to the 1275 ado16 engine.  

 

- A+ 1275 primary gear (29 tooth) 

http://www.minispare...ic/DAM8890.aspx

 

- Front plate

- unsure if this idler will be necessary?? 

 

http://www.minispares.com/product/Classic/Gearbox/Helical%20gears/TUB101310.aspx?1508&ReturnUrl=/search/classic/idler.aspx|Back%20to%20search

 

- mount for the rad

 

 

 - also I’ve read you have to drill a breather into the transfer case since the 998 does not have one. where do you drill that??

 

If I’m missing anything please let me know! thanks in advance

The primary gear change will not give you a 3.44 final drive. It will not change anything it will only allow correct figment. You will need to change the actual crown wheel and pinion gears to do that.

thank you for the correction. do i have everything else correct? any issues with using existing verto clutch?

[Ethel]

You can use the Verto. Either type will fit, you just can't mix 'n match parts between them, that's all I meant by my earlier comment. I think you could save the cost of of the front plate too. I think the only difference is your 1275 with accept an engine mounting that you won't need. It's been over 20 years since I did that swap & I can't remember having to do anything to the plate. I suppose it could foul the subframe / bulkhead & I've blotted it from my memory because it was so traumatic to take a grinder to it  .

 

Drilling the tranny case breather will be obvious when you have it in bits,  you might need to swap or fettle the breather if you have a horizontal brake master/servo.
