Thread: Capstan winches information required

AFAIK they are the same but the mounting plate and drive engagement mechanism differs to suit the different layouts at the front of the chassis.

The drive engagement arrangement of pins-and-holes is reversed in s2s (compared to s1s), though I can't tell you off the top of my head which way they are in each. I'm pretty sure though that the harmonic balancer for a Series one is a different part number if you have a capstan winch. The alloy housing in which the actual bollard turns is different, too, but not very - the Series 1 units have four drain grooves at the base of the bollard, whereas Series 2s on have only 2. I can't remember where I learned that, but it has stuck with me. My 2a has a S1 capstan on it, but it has all the correct 2a drive gear on it.

Hmmmmmmmm

Who knows what's correct and what's not. Some of the earliest LR restos in Oz and the UK have Aeroparts capstans that we know to be the ones that continued to be fitted to S2a and we know that while the capstan was shown on advertising material in the late 1940's the capstan didn't become available till the 1950 model or later. In fact we know that the 1948 and early 1949 model chassis do not fit the mounting plates supplied with the Aeroparts capstan winches and two notches have to be taken out of the mounting plate to fit the winch.

What I believe is: That the capstan winches (and we are talking Aeroparts brand as fitted to the post WWII Jeep) that were originally fitted to the S1 were those stamped AEH . V . **** And are the ones whose design is replicated in the 1954-57 parts manual.



These are the ones with the round front and rear mounting flange and the 4 notches around the bollard to allow the water to run away off the winch.



The series 2 ones were the ones stamped AEH . D . **** and had a flat at the front and rear, plus only two notches around the bollard at the front and rear.



It is not actually the vibration damper assembly (harmonic balancer to some people) it is the "driving flange for fan pulley" Rover Part 218653 fitted inside the vibration damper that is different, it has two posts that engage the winch driving plate. All 2.283cc engines had the groove to fit the capstan on the driving flange as standard.

On the S1 engines the 3 pins that engage the driving plate are on the winch side, while on the S2 4 cyl engine they are on the engine side. By the time of the LR 6 cyl engine they were fitting hydraulic drum winches or Mayflower (M-A-P) capstans which later became the Fairey brand capstan winch so there is (as far as I know) no Aeroparts dog clutch assembly for the Rover 6cyl although an S1 fit may be made to fit.

There are different propeller shaft lengths for S1 and S2 engines.

Ellard,PM Barry2,as his S1 has the original capstan winch that was factory fit & may be able to help.

I could be wrong but the ww2 jeep never came off the assembly line to the end of production with a capstan winch as they were finalised too late
at the end of the war.
The jeep winch were "Braden" later taken over by Linkbelt......Mark

The pics of the AEH . V . winch (above) is the capstan winch fitted to Max Hill's ex-QATB 107 wagon which is believed to be the original fitting up to and including the tubes through the chassis. Unless a vehicle is currently still in the hands of the original owner who has perfect memory or there is documentary evidence of configuration at original sale with an unbroken chain of evidence, the best anyone can say is that something like a winch is believed to be the original fitment.

Isn't that what I said when the words "post WWII Jeep" were used, and it is my understanding that the first ones fitted were the Aeroparts brand? If not, at least Aeroparts is a US Company, today based in New Mexico and their winches were SOME of the first winches fitted to the post WWII Jeeps understanding that other makes were used on the GPA during war-time production and it is likely that these found their way onto non-amphibious models.

Diana. you are right, it is just that they never mention "aeroparts"

always refered to as "Braden" and later "Linkbelt" Re designed the winch
was problematic in early production. probably the same company.
I will go and sit in the corner...........Mark

No need to sit in the corner, unless of course you are working on a 1.6 litre engine!

I have the collars for you next time I pass.

BTW: I always wondered if the straight cuts in the mounting flange, which make the window above the crank handle dog was actually removed by hand after casting or the LR flange casting was re-designed from the GPA specification to make the window for the Land Rover.
