No number Type 4 crankcase

Trike · Post by **Trike** » Fri Sep 22, 2006 4:56 pm

I need help,

I purchased a Type 4 engine which has hydraulic lifters and fuel injection where from the injecter top is blue, but can not find an engine number on the two spots it normally should be.
But found a number on the lower part of both crankcase halfs, which is:
SI 12
071 101 101
As well on the front of the vent housing it has the number: WWO 070 119 225.

Non of the numbers is simular to the normal engine numbers.

Can sombody help and tell me what type of engine this could be??

Thanks on forehand, TRIKE

If it came stock with hydrualic lifter it should be a 2.0, the shroud will tell you if it is a bus engine or a vanagon one. In 30 years it could have been built up to be just about anything.

Thanks Wildthings

I opende the engine today, and it was very the first time it was never bin opend before, it is also clear now that it is a 2.0 L engine with a bore of 94mm and a stroke of 71-72mm.
The shroud is a big aluminium housing on the front of the motor and has the number: WWO 070119 225 (not found on any listing) on the frond of the shroud.
It has also the big flywheel 228mm.
An other point that is different with the type 4 engines I have seen before is the the differnces in the breather tower, those I have seen had a seperate filter on top of the breather tower which can be removed, this one has a complete closed breather tower with a black plastic cap in which the breather hose connection, the black cap can be removed.
And also this one has the same problems as common with Type 4 engines, a worn cam axel.
I supose that it is a GE or a CV engine, but who knows.

So it is still a mystery for me why there is not number, but may be with this info you can help me a bit further?

Thanks again for your reply, and thanks again on forehand for you follow up.

Best regard,

Trike

Sounds like a vanagon case.

Thanks again Wildthings,

You bin a great help, in this matter.
Now I can assume that the engine I have is probably a CV engine 1980-83, one of the latest Type 4 air cooled machines.
It seams that you are more an expert in Type 4 than I am, so I will occupy you with a couple of more questions, if that is OK from your side.
1- Here in Sweden is hardly any information about those engines available, do you know the different torque requirements with a rebuild of the engine, or know a good website to get them?
2- I wont to change the fuel injection in to a one dual carburetor, I look on some US sides for an EMPI but it is hard to pick the right one in that jungle, do you have a good advice, I plan to keep the engine standard for now.
3- The cam axels from the Type 4 have all a big problem that the worn quit fast, is there any way to solve this problem?

This engine will be build in a mid engine trike, so not the standard tail engine trikes.
This type of design makes the trike way more stabile on the road and looks way better also.
The engine will get with this a better and easier second life, due that the weight of this trike is not more that max. 450 Kg.

See forward to receive your advices,

Thanks spending time on my questions,

Trike

1. For torque specs try looking on Type2.com or Ratwell's site. Better yet pick up a Bentley or Haynes manual, or at least an Idiot Book.

2. Dual carbs for these engines are needless complicated and take a lot of tinkering. I know that a lot of people run center mount progressives for buggy or trike use, maybe they do not have much of an issue in such a light vehicle, but they certainly do in a van or a car.

3. Cams and lifters can last 300,000 kilometers in street use. I wouldn't worry about it at all in a trike.
