Help needed fitting winch to S3

[Romeo]

Hi Guys,
My lad is wanting to fit an Aeroparts winch to the front of his S3, and has almost everything he needs except the bit that I think is called the driving plate (ie, the disc that bolts on to the crankshaft pulley, with three round pins in the front, and two rectangular keys poking out the back) . To me, it doesn't look very hard to make this plate; nor is it heavily loaded (only has to compete with a small brass shear pin!) so the material probably doesn't need to be very clever.

I can have a guess at the dimensions, but it would help me a lot if there was someone out there who could maybe make a few measurements (specifically, dia and length of the three driving pins, dimensions (esp length) of protruding keys on the back, and thickness of plate body.
The pictures I have been able to find suggest that the disc is centred simply by the protruding keys locating themselves radially on the end of the crankshaft - is that correct? If someone could take a snapshot of the back of the disc that would be a big help!
Thanks in anticipation...

Sorry I can't directly help, I need the same part my self at some point (plus the driveshaft, operating lever & fairlead brackets).

Does the crankshaft have a couple of cutouts for the tab washer and the 'keys' locate in the cutouts ?

Thanks for the reply. I had seen those particular pictures - not much help, unfortunately.
It may just be a terminology thing, but I'm not sure what you mean by your question. The attached photo may hold the answer.

Thanks Jim,
I had seen their site. I had another look but could still not see the individual part I was looking for, not any reference to "the book they supply". Is it a "You have to register" thing?
My hobby
(one of many) is machining so I am keen to make this thing, anyway.

Looks like the 'keys' on the rear of the drive plate locate in the grooves in the crank pulley.

Shouldn't be hard to make.

Yes, that’s what it looks like to me, and I expect that they reach back far enough to center on the crankshaft itself. But some actual measurements would be great confirmation!

The bit you are looking for (I think) is actually replacement for the standard starting dog, and is one side of the dog clutch that engages the winch. The notches in the crankshaft pulley are for the locking washer, not for driving The arrangement was somewhat different over time.

Series 1 and, I think, Series 2, had a three pin dog, circular in appearance, with the driven shaft held in a bush supported by brackets off the front of the engine to keep it aligned, with the shaft sliding.

Series 2a and Series 3 had a dog with a deep groove across it to take a cross pin as the driven side of the dog clutch and with the bush in a bracket hinged off the front cross member.

For the later one the part numbers are RTC7015 for the 3 bearing engine, RRC1582 for the five bearing. I don't have the earlier optional equipment parts book.

John,
The drive plate in the parts book (I cannot find a photo) has two square 'keys' attached to the back that look like they drop straight into the cutouts in the pulley for the lockwasher.

This version has cutouts for the lockwasher and ?? Maybe a different method of keying to the pulley ? Without a key of some sort you are relying on friction between the drive plate, pulley & HT bolt to provide the drive.
Looks like the drive plate changed over time as you mentioned. Mine has the 6-pins which means it must be later.

Once I find time I'll look at making a drive plate but I also need the driveshaft, fairlead brackets and operating lever. The operating lever should be easy to replicate and the fairlead brackets could be repaired if I can find someone who can weld aluminium.

I'll have my optional equipment parts book in Cooma - you might be interested to have a look - the setup is quite different to what you have pictured (which is similar to what I had on my Series 1 and Series 2).

Colin,
yes, that sounds like the part I have been referring to. I am a tad out of my depth here, but looking at the parts diagram in the manual for the winch, it seems that the 2 l petrol version and the 2.25l arrangements are quite different in this area. (and a later version with quite a different drive arrangement). The 2.0 version has the 3 pins sticking out of the part on the winch, with a plate having 6 holes attached somehow to the crankshaft pulley (noting your further comment about that). Your first photo shows bits that appear to belong to that one, but it’s not the one I’m after. Two square keys at the back, and 3 round pins at the front.

still hoping that someone has a plate like that and can make some measurements....

If you have the mating part and the pulley on the engine you should be able to work out the dimensions.
The only problem might be the HT bolt, if you cut the starter dog off the standard bolt the hex head may be too big but you could mill it down to a smaller hex size.

I can't find a picture of the drive dog but it's in the Series I & II parts manuals. In the Series II manual it's listed for the 2.25 Petrol & Diesel.

Colin,
yes, I may end up having to guess the sizes, but, for example, the holes in the driven plate are some 11.4 mm dia - are the pins 3/8 (lots of clearance) or somewhat more snug? And how much axial clearance is normal when the winch is disengaged? Etc, etc...
sure I can guess, but normally the wonder of a forum like this is that someone is willing to share the info.
the bolt is no problem, really. Just ordered a couple of GR8 3/4 Unf puppies on flea bay for not much. May have to trim the head a tad, but that’s easy. Don’t understand why it’s a HT bolt - it’s not doing much!
Anyway, for measurements....
Still hoping.....
