Crow Posted March 9, 2020 Report Share Posted March 9, 2020 Can anyone give me a idea of why or what’s worn in a Enfield outdrive ,it rattles terrible in neutral, but is quiet as a mouse in fwd or reverse , will it be the top bevel gear mating to the vertical shaft wanting shimming out or in on the back alloy casing thank you, Nick Link to comment Share on other sites More sharing options...

There are dozens of possible sources of the rattle, you would really need to work down the list of things and see which is worn / damaged. Link to comment Share on other sites More sharing options...
Crow Posted March 9, 2020 Author Report Share Posted March 9, 2020 Thanks ,I mistakenly thought all Enfield legs were the same inside,I’ve stripped enough, it’s a 130 wind up one,all bearings and bearing surfaces are good, no lift or play on any shafts, it’s just real clattery ,if that’s a word , but only in neutral ,I’ve looked on the net for good pictures and tolerances but they all seem to blurred to see, Link to comment Share on other sites More sharing options...

Crow Posted March 9, 2020 Author Report Share Posted March 9, 2020 It’s the 130 swivel. I have found a reference on the net for a 7 to 12 thou clearance on top vert and horizontal bevel gears,I’ll get some plastiguage tomorrow and see what it’s got, that’ll be a start, Link to comment Share on other sites More sharing options...
harrybsmith Posted March 13, 2020 Report Share Posted March 13, 2020 Could it not be the leg but the rotoflex rubber coupling? They can rattle and go quiet when they get squished under load Link to comment Share on other sites More sharing options...
Crow Posted March 13, 2020 Author Report Share Posted March 13, 2020 Thanks for reply buddy, there is no rubber drive in the joint,I have 2 back to back c/v joints to defiantly take up any misalignment, as I’ve been plagued with chattering and vibration for ages,that’s cured it but sounds in the leg to be making a lot of noise,I’m waiting for some plastiguage coming so I can see what gaps between the meshing planet gears Link to comment Share on other sites More sharing options...
magnetman Posted March 13, 2020 Report Share Posted March 13, 2020 (edited) Not sure if you know them already but Chertsey Meads Marine know a lot about Enfield legs it would be worth dropping them a line. They are helpful and knowledgeable. Old school type of boatyard. https://www.chertseymeadsmarine.co.uk/home-2/ I know nothing about z drives as have never interacted with one but if you have bypassed a rubber coupling device could this be the reason for the problem?

Crow Posted March 14, 2020 Author Report Share Posted March 14, 2020 No buddy them rubber drives are 1960 s. A car front drive shaft works at all angles and up and down ,with cv joints inner and outer, and mercruiser legs have them.it was making noises well before I altered the coupling, Link to comment Share on other sites More sharing options...
