This is a good question. I myself have one engine that has been around the clock three times still going but?? and one that has only done 76 thousand miles. The later I can not get running after pump being repaired and put back on. this pump is a Boche. now if I wanted I would like to know if the pump from my other engine will fit it as it is a cv rottory. If some one answer you, I will know the answer and can keep my nackard pump engine for spear. cheers Pete

hi, found out by trying that you cannot swap pumps, they look and fit the same but bocsh one ofset on engine so timing out, asked diesel spec who do fit and rec pumps. they wont fit as years ago they tried, pity that so i am still looking.

I have noticed that my white combi the pump has more room at engin side. She just failed mot on uj gators near side and lower arm ball joint, so that is being done latter today, If in the near future I can not get anyone or tool to retime my other pump. I will keep you in mind Cheers best of luck with your search other wise, Dieselcombiete

Hi Again. Since my last post to you I have gave this some thought I now see by reading my manuel that no matter what pump you fit it seems to be the same prosess, the engins are deffinatly the same and the offset must be aloud for in the pump itself. I now believe you can fit either pump. As there is nothing to the contrery in the manuel, it just say the engine can have either pump fitted. but you will have to get the new one retimed with a presure gauge as per the manuel, as any marks you should have made when taking the first one off, will be no good for the new one. Cheers Pete

tried the other kind, timeing cannot be adjusted enough, it seems some engines had 3 more threaded screw holes so u could remove studs and replace in other holes, timeing easy then, but most will not, i am still looking, even thinking if can get one a 1800 non turbo

I have of late. had hell with both my two combi's. One is fitted with the cv pump and the other with the bosh.
Now take the two pumps of both engins and the make up of both engines without the pumps are dead the same;= where there is a hole in one, there is a hole in other, where the tdc mark is on one it is on the other, how the three gears from crank to ideler to pump line up is exactly the same. What I am saying both engins are carbon copies of each other. I know this as I have stripped both mine down.
Okay thats the enging. now take my cv pump it is the same as any cv pump from the same size enginge this is, the hole in the outer casing are in the same place as any other cv pump. Then there is the bosch pump; this one two is exactly the same as any bosch pump taken from the same engine. ( engine in my case being the 1600cc) now the bosch pump I know is the same as have had it along side one the same.
Okay so all this being so . one pump should be intercahngable from one engin to the other, baring of coures any static timing needed to be done with pump on the car, you could not mark engin with one pump for another. Hope this is clear so far. (Mind you with the two engins side by side and transposing the makrs with some clever mesuring. what I just said my not be true????)
Okay when you take the basch pump off, you pull it out from it's gear on the end. You do need to hold this gear in place before you pull the pump out, the reason being it is only held in place by the pump drive shaft. If anyone pulls out the pump without holding this gear in place.. I do not know what the result would be. But the chances are your pump would not be anywhere neer it's needed position. ????
Just a few thought Hope it give you food for thought and gets other answering as even people that do not know enaything can have there say if they have any ideal. I way up any thing and anything that is said. Anyway for now I am working on getting my number one combi starting better. I have her overheating sorted it was the bypass hose from the pump to the thermostat housing blocked. Now what a dream she is to drive. Cheers all. Diesel combi pete.

i thought they were the same but if i put bosch on its say 1in over to the rt against my cav one, took it off a scrap earlier engine, will not operate in this position, i locked everything so pully does not come out of mesh. my mate works at dale diesels where they do nothing but repair pumps and fit them, says they have tried before but wont work,i can have one for 100pounds but will not run it. i bet there is a way as it fits but timeing way out and not enough turn on pump. on my 2 engines thought the studs looked the same but on measuring 20 times realised they were not in the same position, but to look at it they are

Diesel combi pete

Well, sorry you cannot get it sorted, I love my combi's and would hate to be without one on the road.
My two engins are four years apart age wise, also in the book all 1600cc the same. Also you take it from me on the 1600cc the pump gear must be held in place before pulling pump out. I told you this incase this is what could have happend to your engin, people do do these type of work without reading the manuel and takeing out the pump without holding this gear is so easy to do as this is how it is done on most motor,
BUT NOT on THE 1600cc. Other wise ???
I know my to pumps will change over for as I have said their phisical make up of both and the engins are the same.
You would think we would get some more comments on this subject would'nt you? All coments welcome.
Any way I will go right through my manuel tonight and see if I can download the part about holding the gear in place. I will try and post it for you , cyl Cheers Pete.
