Hello, i,m in the precess of swapping a knackered 1.6na diesel (which i was told by the previous owner it was not the original and had come out of a golf- not sure ) for a 1.9 1y. I've done lots of searches on here and have all the info and bits (i think) to carry the swap out, but have come accross a problem with the oil pump drive. My bus is a 1982 joker from saudi arabia and does not have servo assisted brakes. Don't know if this is because of its age or where it came from...

So the problem is that the old 1.6 engine has a machined cover which clamps in place of the vacuume pump and a drive gear on the end of the oil pump ( which is splined instead of having a flat on the end like the 1y). The drive gear picks up from the end of the intermediate shaft (I think thats right) and does the same job as the bottom part of the vacuume pump would. Sorry if all this is obvious to any or all of you, but tying to give as much info as poss...

So here's the real problem. The drive gear from the 1.6 and the 1y (on bottom vac pump) are different sizes, so when the oil pump from the 1.6 is fitted to the 1y and the drive gear attached it doen't ingauge with end of the intermediate shaft.

So in a very round about way, does anyone know if i can fit the vacuume pump, but not attach it to anything, or any other ideas??

Thanks very much in advance and happy easter!!

Wish I could help mate, I understand what you are saying but I dont know the answer. Can I suggest you put this in the "Technical Questions and Answers" bit as I am sure more people visit that bit. Good luck.

(Yup just had a look and approx 60,000 posts in Tech Quest and only 4,500 approx in the Alt Eng)

Thanks for that Pete Abbott, will give it a go
