Converting to spade drive oil pump

[linearaudio]

Having found that the original oil pump had 3 fixings, and the spade type one for the "wondercam" has but 2 diagonal, do I need to look for an adapter plate to mate the one with the other?

Change the pump for the pin drive variety then sell the spider drive componants on - They are rare as rocking horse pooh these days....

You must use a spade oil pump with MG cam - just drill & tap more fixing holes if you need them. If for a 1098 engine - you need the 'short shaft' pump - if for a 1275 you need the 'long shaft' pump. The spider pump was only ever available in long shaft form - for 1275 engines - yes yes, and the 970 and 1071 S engines !

How come in all the threads about the "wondercam", nothing has been said about drilling and tapping(did that!) or the different length pump shafts (think mine must be a long shaft as the cam won't go fully home )

I have mentioned both items many times in the past - almost as often as the W brakes! Some pumps don't need any drilling /tapping - just depends which brand of pump. The long / short shaft pump is also a 'well known fact'. Long for long blocks (1275 and S) and short for short blocks (803/848/948/997/998/1098). As before - spider pumps were never made with short shaft.

I obviously missed the many mentions due to it not being one of your controversial subjects
