My major has been slowly progressing... going on 9 months now Getting ready to put the motor back in the car, and found a leftover circlip!!! I had it in a ziplock bag which also contains all of the old cam cover acorn nuts... The circlip is about 3/4 of an inch... Of course, now I am starting to enter into a full panic. I don't remember a circlip anywhere during the major, with the exception of the armature in the starter while changing bearings... First thought was, is there a circlip when installing the water pump?! I dont remember one... the manual doesnt seem to show one... I dont remember a circlip when adjusting the valves/cam timing either... Now it is possible this circlip isnt from this car... I was working on my 930 and 914 at the same time... But it was in a ziplock bag with cam cover acorn nuts... I would really appreciate folks input on this. Is there an external circlip one removes at any point to do a major? Anywhere? I know that in the area of the water pump there are two circlips on either side of the bearing, but I didnt remove the bearing. And those are internal circlips, and the one I found is an "external" one with the ears on the outside, intended to be slid on the outside of a shaft... thanks Image Unavailable, Please Login
Have not seen one like that during a major. Perhaps you found it on top of the engine while pulling the cam covers(?) No panic - Cheers, Vincenzo
has this nut a 10 mm head or a 12 mm? what thread does it have? the circlips for the waterpump bearing are "inside" as you already have written. I think that this circlip is not from this car? at the gearbox shaft there is a circlip ( 11067376 ), but I think with larger diameter.
Thanks guys. The circling for the bearing and injectors are internal circlips. I.e. the outside of the circlips is a perfect circle and the ears are on the inside . This circlips looks like it goes on a shaft and the ears are on the outside...
Is there one on the starter? Maybe to limit the Bendix excursion? I recall that was a round X-section ring. I feel for you. I played my EO service over and over trying to think of external Circlips ??? Is this a TR or BB ? I also thought throttle shafts & linkage, but those are smaller ? ? ? Distributor base? ? ? (also smaller I think)
Good day Bo, Peter is right... there are two of these located on the waterpump on the Testarossa and one on the Boxers. However, the boxer clip is just over 32mm in diameter... Sadly, I do not know the dimensions of the Testarossa ones. Cheers, Sam Image Unavailable, Please Login Image Unavailable, Please Login
Yep, those are the only two I can think of. But they are inner circlips, not outer circlips. Thank god, because I really didn't want to disassemble the water pump...
looks like the rounded nut is from the air intake, should be 4 nuts like that, or the exhaust / gas analysis tubes, (there are two of them). if not, not sure where that nut came from.
Just one part left over? Heck you are doing great! Any idea from where it might have come on the Porsches? What were you working on with them?
Nut is just in the pic for reference... I am constantly working on these cars... heck if I know what its from. I was rebuilding the alternator in the 930 6 months ago... its working great since... Sometimes I wish I didn't have "old man brain" kicking in... As long as its not from under the water pump or under the cam covers, the rest is easy...
If the manual pictures are this good you should be able to locate it OR confirm that it cannot be from this car via the pictures Pete
you have not answered yet my question: has this nut a 10 mm head or a 12 mm? what thread does it have?
ok thanks, so it is a 10 mm with M 6 x 1 it looks larger than 10 mm in the picture, that is why I asked
Bo, Did you do anything with the drop gears or input shaft? In doing my 308 clutch/rear main seal work there were a couple of those snap rings on that shaft as I recall... Still thinking about this. CC
308 input shaft is totally different to the TR shaft and the system is other. I also remember when I did a 308 clutch first time this clip ( without ears ) and the bushing I had a little problem with. the other is an inside clip
