My guess is some kind of governer to ensure the engine runs at constant speed when used in an industrial application?

Correct -
The additional belt drives the governor, which ensures a carefully controlled speed

Hi All

Yes the extra belt is a governor, can be removed, it is adjustable as well, just remove the belt to remove. also has what seems like an external oil filter on the left where the coil would usually sit.

Stuart

they look like the super 90 engines - are they?

Hi Didi

yes, don't want to buy stuff for people on Dib's, then they pul;l out cos they have not got the money, no offence to anyone, but i see it very often. guys want stuff but when it comes to paying there is a problem.

Stuart

Just confirmed that the cam may also need to be changed, spoke to the supplier, can do them for R 11 000-00 as is but started.

Hi All,
Just thought a bit of 1st hand experience may help. I bought one of these motors from Aucor a long while back. It cost me R5K. At that time there were around 50 in a container. Mine was as described above but was not shown running. I had some 356 bits at home so thought this would be a great engine for the Karmann Ghia. I have owned several 356's so know a bit about them.
Let me clarify what is different about the Porsche industrial engine externally at least.
Flywheel is heavy duty and has starter teeth on the outside - its no good for use. I found a Super 90 flywheel at Volkspares and fitted that.
It has an oil drain pipe attached to the sump. This needs to be removed, and the threaded hole left needs a blanking plug. Made one up.
Mine had a Magneto. You can't use it as has no advance and retard. I swapped it for a 009 dizzy.
It has all the governer gubbins. This must come off. You are left with the gnerator (12v) pedestal which you cant use as it now has holes everywhere. I managed to find an original 912 pedestal on ebay. Now the oil filler doesnt fit - I made an adapter plate.
It has a single carb and maniforld - again no good. I eventually found two Solex PC40's and manifolds and fitted them.
You have to find the linkage and make brackets to fit the fan housing. Not easy but I did find/made eventually.
You have to find the right tinware as the ones fitted are for industrial use only.
The silencer looks like it wont be right, but in fact I found I could use mine in the Ghia.
At this stage I was able to fire the engine up using a Ghia chassis I was building as the mounting. First time around it caught fire, backfiring through one of the carbs (a 356 idiosyncrosy). No major damage and after this It did then start and run. I had fitted an oil pressure guage and generator light just to make sure things were OK. (BTW the filter referred to in a previous post is a real 356/912 filter in the correct position!). Both oil pressure and charge looked good.
I then found that the cranklshaft generator pulley was not the correct size - it was too big (must have been fitted due to different rate of charge when engine was in inustrial guise). Oil was also now pissing from both the front and rear crankshaft seals which had gone rock hard due to many years of inactivity. Replaced both. Suprisingly the push rod tube rubbers were still fine.
Engine ran up well, and had a lot of power and mechanically very quiet. Decided to start a top end strip as had heard valve springs were soft and had a milder cam. Found that valve springs were 912 spec and NOT soft at all. Decided not to strip to check cam as everything indicated that engine was like new inside, and seemed a shame to disturb. Put engine aside until Ghia ready for the road.
Some time later fitted engine into Ghia. Fits OK but up very tight against firewall, so had to modify aircleaners, and linkage anbd had absolutely NO access to top engine mounting bolts, and adjustement of linkage. The 356's have a rod for the accelerator - not a cable, but had to modify cable to work and am still not happy with arrangement. Its sloppy and needs a lot of pressure.
Once engine in car used 356 instruments so had the oil temp guage etc as standard. Engine now running sweetly and clutch working well.
One thing I can say is that it is powerful. EXTREMELY powerful and works well with the 1302 box I was able to find. The engine is basicall a 912, so its probably putting out around 100 horse.
Would I buy and modify back to 912 another one? Maybe - BUT it is costly if you want to bring it back to 912 spec and the parts are not easy to find. Does it make a huge improvement to the Ghia - I think a resounding YES. Anyone thinking of buying and then modifying one is welcome to contact me/see mine. These industrial engines never did much work, and what they did was at a governed 2,000 revs odd so inside they are like new. They are also extremely robust and will last for years without work. Best of all tho' is the power, so if you do get one get a disc brake upgrade as well!

A well balanced assessment Webster...!

I too bought and sold 5 of these industrial engines a few years back, and most of them were either used as farm gate openers or ski lift motors...All of them needed all the work you mentioned on top, but were sound on the inside. These motors were strictly Low rev but Hi torque motors and were governed between 2000 and 2500 rpm depending on the application, and the spec of the cam shaft. These need replacing as Webster stated as they are useless for Automotive use. If you compare the size of the cylinder heads to those of a beetle and kombi, you will definitely see where all the power Webster speaks of come from.

I eventually gave in and sold mine to Motor Masters, and to Dirk Mathee who needed the heads for a Porsche client.

nice don't know where the 914 fits into the story?

Thanks very much Webster, I thoroughly enjoyed reading that . The casual way you described the engine catching fire made me smile.

You can buy a 356 flywheel from these guys -http://aapistons.com/index.php?main_pag ... 5ce09db584

I have a 200mm Type 4 flywheel from AA and it's of a very high quality, even though they are made in China
