ditchman Posted May 29, 2016 Report Share Posted May 29, 2016 Mate came round yesterday with a mariner 3.3 outboard engine ..that was given to him by some "boating chancer"...you know the admiral type ...yaght club blah blah blah......take it away its seized old boy ..what what ...donchya know!! anyway i started doing stuff to it and found out ...it had been laying on its side for a couple of years and water/condensation had gone into one of the crank bearings (ball) and rusted it...also found out that one of the end seals was inside out.......the engine has never been split so it was put together wrongly.....ordering up 2 bearings and 2 rubber seals ........jobs a gooden...

ditchman Posted May 30, 2016 Author Report Share Posted May 30, 2016 you can see the throw of the crank...and how close the bottom of the piston gets to the balancers on the crank...so if both bearings gave up it would hit the piston skirt @ 4000rpm...........

Schmitty Posted May 31, 2016 Report Share Posted May 31, 2016 (edited) Ditchy... If you can provide seal and bearing numbers (sizes not part no.s) and they're nothing too specialised I may be able to help you out Edit to say... Just spotted the location pin in the bearing so likely to be a special but a man with your talents could surely add a dowel pin to an outer bearing race.

ditchman Posted May 31, 2016 Author Report Share Posted May 31, 2016 seals anrnt too bad and i can get them locally fairly cheap....the standard bearing is cheap as well...if i had drills up to it i would remove the dowl pin and drill a hole in the new ones and bobs yer uncle.............just need a drill that could drill into a bearing race........... still working on it..........
