    Water Pump Pulley??

    So I promised an update once I got back to the boat but I'm sorry to say "I bottled it"! I started by taking some basic measurments of another 1.5 engine (Red) to be found at the marina the boat is currently birthed in. This has an additional drive for a raw water pump mounted on the front of the crank which my engine does not have. From the rear of the water pump pulley to the alternator mount was 46mm. From the timing chain cover to the rear of the crankshaft pulley was 10mm. Taking the spacer washer into account this confirms my thought that the crankshaft pulley has been shifted forward on my engine for some reason, by about 10mm. I then tried to free the crank pulley but due to time constraints and an element of it aint broke (much) this is when I bottled it. The owner was keen to get it up and running and I had the starter motor (referbished again, properly this time) and the referbished alternator to refit. Since my previous visit I had made up a crude packer with my limited woprkshop facilites. At least it offers a little more support than a floating washer. The starter motor had a seizing gear, worn brushes and a sticking solienoid. The alternator, well, became "Triggers Broom" with new insides, regulator with increased output voltage, bearings etc. With these refited the engine fired on the very first turn with 20secs preheat. This is something it has never done before. So as pointed out by you guys a shot starter was the cause of the poor cranking. I'm now hoping that the refit lasts, certainly enough for the boat to get nearer to home so that I can spend more time fixing rather than traveling. Once I get to revisit this I will update the post but for now it appears to be running with an upgraded bodge.
  2. Fortunatly they came out without any issue nor showed much in the way of carbon build up. My point was that I did not expect the drill to be a sloppy fit. I would have thought that its size was choosen to match the size of a clean opening.
  3. I'm new to the engine so learning my way around it. I purchased a drill specifically for the job and its 126mm long and it went a long way in. It almost felt like the hole was say 5mm in dia.
  4. Are there different types for this engine? I have recently replaced a set with like for like after finding one dud. I made a nice bus bar make the connections neater and more reliable. During the replacement and refering to the manual and the good advice here. I used a long 11/64 drill to ream out the holes but the drill was a loose as anything down the holes and did not bring anything out. Is this normal? I was expecting the drill to be the exact size of the hole. I should have tried other drills to see what size the bore was but did not have a set with me. This is what I have installed The enging is slow to start due to a poorly starter motor but once these were fitted and all 4 were glowing it was much happier.

    Water Pump Pulley??

    Gents, thanks. What I'm rapidly realising is that on something this old is expect the unexpected and "normal" is loose term. I wont be holding anyone liable, I'm the one in front of the thing. I have to use my judgement with the help of your fine advice. Expect some more questions after my next visit, hopefully this weekend. Hmm just though of one but I raise that in another thread.

    Sam thanks for the advice, especially the above! Obvious really but its all to easy to take things for granted and thats when you get bitten. As the starter motor is off for referb I think I'll take the pulley off.

    For clarity, the black water pump shown is a new 60mm one from Calcutt. I did not conduct accurate measurments but in the 3rd picture you see a step in the casting. From there to the flange was the same distance as the pump fitted on the boat if I recall of course that is not the same as measuring to some reference point on the engine. As it looks as though I might be taking the crank pulley off, I need a spanner or socket to fit the bolt mine dont go that large. I read that is 1 5/16th AF does that sound right? Would be good to have some means of rotating the engine by hand.

    True enough and point taken

    The wrong water pump is what the combined consensus is appearing to be and at the moment with the quality of the bodge found, I could expect anything. But there are also spacers on the alternator so that is why I'm thinking there is something else been done with the crank pulley. Hopefully I'll be back to the boat next weekend

    Hi Richard so appart from thier dia (do you happen to know what it is so I can measure) do they have a different belt projection? If they do and it is fairly common place what is done about the water pump?

    Water Pump Pulley??

    Thanks all. I have just had a conversation with Calcutt and they concurr that it could be the wrong water pump or flywheel the forma being the most likely. They also said that people do alsorts make the pumps fit including changing the bosses. etc. They said take the pump off and have a measure. If it were the wrong water pump though why would the alternator need spacing too? Either way looks like I'm consingned to another coulpe of visits. There is an old engine at the yard so now I armed with the info here I shall have a look around it with a more educated eye and take some measurements.

    Ok so the crank pulley should come off and is aligned by a keyway. If it is keyed could it have been put on the wrong way around? The alternator has been packed too. Everything is forward by about 10mm.

    Water Pump Pulley??

    The unused tank is inside and made up as part of the hull. The other side is external, thats what the pipes suggest as I have not seen the boat out of the water. I guess its always possible that the engine has been changed at sometime too. The header tank has got Calcutt on the side so I guess they did the marinisation of the engine. So do I pack the pump pulley or remove the crank and any packer installed? Is the pulley aligned in anyway, on a keyway etc. cant see from the manual. I'm just worried that the crank pully has been packed to over come some other issue or maybe its not the right one? Two years... going to keep me busy then.

    😉 please I dont want to be going there. What's amazing is that it has obviouly been like it for a long while given the paint.

    Thanks Sam, starter and alternator away for a referb. I assume the belt has just worn cos of misalignment or strain from a poor alternator bearing. As for the pumps I saw that there are different sizes and that the 60mm was the most common. So I purchased one of these. Externally it looks identical to the one installed but did not want to take the pump off to check on the impleller if I did not have too. The suggestion is that the crank pully has been spaced out. I say this as the alternator has also been packed out. At the yard in the marina was an old 1.5 and the pump pully seems to be same. If you look at the last photo of the crank pully it looks as though there is a plate behind but I'm not sure if that is the case or is normal? I should have checked that on the old engine while I was there. I can't see any signs of it but there could have been an external water pump at some time but then I would have though there would be two crank pullies. There is an internal skin tank and header tank (no longer used) on one side. On the other, is another skin tank this is the one being used with a tap off for a calorifier. All run off the engine pump.
