Throttle return springs
Posted: Mon May 29, 2023 3:59 pm
Hi Folks,
As usual I'm slightly confused, and hope someone out there can help!
Firstly, how many throttle return springs should be fitted to the 3.8 litre engine? I appear to have 3, whereas the workshop manual (W.S.M.) shows only 2.
As found, I have two springs attaching to the actual throttle shafts, via little "bell cranks", (item 54 on page C4 of the W.S.M., and also item 55, which appears to be incorrectly identified.) On my car, spring 76 attaches to bracket 77, and then onto the carburettor nearest the windscreen, via the bell crank labelled as 55. I then have a third spring attached to item 83, (also on page C4), and then onto bracket 74.
The second part of my query relates to where Bracket 74 (74 0n page C4 ) attaches to the car. This was providing the lower fixing point for the unidentified throttle spring. As found, bracket 74 was attached via two of the nuts securing the inlet manifold, whereas recent information indicates the bracket should attach via the two lower studs securing the front-most carburettor. It doesn't help that the numbering in the parts book (plate 7) differs to that in the Workshop Manual (page C4) !
Can one of you kind folks please put me out of my misery!
Regards to you all in Jaguar land.
