ace1 Posted June 5, 2014 Share Posted June 5, 2014 Hi All. After my broken pushrod incident, now sorted thanks to Ed:-D, someone said that the water pump getting tight could cause this. Is there any way a fault with the pump could cause this?:readbook: Kind regards. Alan. Quote Link to comment Share on other sites More sharing options...
0 ace1 Posted June 11, 2014 Author Share Posted June 11, 2014 Hi Chaps. This must be a difficult question,:wow: either it is complete flannel, or there is loads of great minds looking at books, without finding the answer. Looking at the drawings for the 6LW, if the water pump seized it would strip the gear on the drive shaft, or twist the shaft itself. That is my opinion anyway. If there is more opinions out there please share.:tup:: Regards. Alan. Quote Link to comment Share on other sites More sharing options...

So the big question is - how is the water pump feeling? trevor Quote Link to comment Share on other sites More sharing options...
0 ace1 Posted June 11, 2014 Author Share Posted June 11, 2014 It feels ok, but I don't have another to compare it to. Went to Tangmere aircraft museum last Sunday, there was no unusual noises coming from the pump, and the rad was warm all over, so I assume it is working ok. Regards. Alan.

0 Niels v Posted June 11, 2014 Share Posted June 11, 2014 Hi Alan If the impeller seizes the square part on the back brakes off to avoid damage to the drive shaft across the engine Quote Link to comment Share on other sites More sharing options...
0 ace1 Posted June 11, 2014 Author Share Posted June 11, 2014 Thanks Niels. So that is the "safety" part of the system, there is no way that a tight water pump would have any effect on the pushrods or their operation. Regards. Alan. Quote Link to comment Share on other sites More sharing options...
0 Scammell4199 Posted June 13, 2014 Share Posted June 13, 2014 Broken pushrod incident!? Funny you should say, cos I'm part way through rebuilding the 6LW fom our Pioneer and some of our push rods are worn through on the ends. Think we might need some new ones.
