Capstan winch. Will a SIIA winch fit on a SI?

[Aaron IIA]

I have just acquired a 1949 Land Rover. I would like to know if the capstan winch that I purchased for my SIIA (from another SIIA) will fit on my SI. I am guessing that the selecting bracket that bolts to the sump will be different.

Pretty much the case. the actual winch is identical, but the drive setup varied. The brackets etc were different, but also the assembly that holds shaft to the winch at the engine end. Note that the type of dog clutch and various other bits changed from Series 2 to 2a. Earlier, Series 1 & 2, had a sliding dog clutch engaging with three round pegs, but Series 2a/3 the dog on the crankshaft had a slot engaged by a crossbolt on the shaft with rollers on the crossbolt, and this, instead of sliding, was in a swinging bearing. Similarly, the earlier lever was a sliding action, whereas the later one was a pivoting action.

But I would expect you could adapt the S2a/3 one to use on the S1, although it would probably require access to welding and possibly machining facilities, unless you can get the original Series 1 drive bit; but I think hen's teeth would be easier to find!

Hi there

It can be done - as I have a IIA capstan winch on my 1954.....

I just made up new brackets on the side of the engine - and also made up the dog clutch- the S1 manual has a good diagram which I used to fabricate the extra parts needed.

All the best

PS will take some pictures when I get home next week - back up north again.

Hi there

Here is a picture of the series II-III capstan fitted to my 80"

Take note of the fabricated brackets on the front of the engine - this has now been removed from the 1951-80" and has been fitted to my 1954- 86".

Thanks Wayne and John. Looks like I have some light fabrication to do. But it will be worth it.

It sounds like I have a SII capstan, as it has the 3 pin clutch, and the sliding actuator lever. It is SII and not SI, as the bracket fits perfectly onto the 2.25L sump. Although I suppose this would also fit a SI 2.00L Diesel sump.

G'day All, Wayne in your pic showing the Capstan, is it just sitting there, reason I ask is that the base plate is normally held to the x member by a series of Riv-nuts aka nut serts and I cant see any evidence of those? cheers Dennis:wasntme:

Aaron,
I think Diana (Lots-a-Landies) or Bob (bobslandies) had some adaptors fadricated for fitment of Capstans to the Series I's.
If they don't post here soon maybe you could PM them for details.

Yes your right - it was an early picture within the modification process and I used nut-serts with spacers.

All the best

There was a capstan winch in a 51 80ich i was given, am i right in saying that the series one capstans are different to the series twos or is it the way they are mounted. Anthony.

The Capstan winches on the Series 2 and Series 1 that I owned in the sixties were identical, and both were fitted from new for the SMA.

Although that was not an 80" (it was an 88"), the ones I have seen on 80" and 86" Landrovers have also been identical as near as my memory serves, although there were probably small detail differences through time.

Roger is correct - If I don't have a spare set of brackets at the moment I can get some made up. I have all the CAD drawings and a laser cutter who will cut the elements and also a welder with a welding jig built for the purpose.

The only things you need to do then is drill an extra hole for the S2 bearing block (different place to the s1 type) and have the flange in your S1 vibration damper slotted to accept the S2 drive plate.

The last lot of brackets I had done cost $80/set.

Although planned from the pre-production stage Capstan winches only became available in 1950/51 so most of the 80" vehicles now with them have actually been retrofitted.

The Aeroparts capstan winches known to have been fitted from new on several 86/107 Land Rovers have a base plate which has a continuous curve from the front LHS around the bollard and finishing at the rear LHS. These also have drain notches in the ring around the baseplate and an "A" suffix.

The series 2 capstan winches and often seen fitted to 80" as well have a flat at the front and rear of the base plate. This is probably a modification for the 88/109 models because of the shorter space in front of the grill panel and a "D" suffix.

There is also a difference in the drive shaft length in some models.
