Hi Adam......I see what you are saying re Mr Plod needing a brief burst of speed occasionally,The Marine engine runs at a constant,speed/revs for 2/4 hrs at a time.The Hull is a semi displacement hull it did do approx 10knots when tide /wind/load was favourable.8.5 cruise but wanting a bit more with new engine ,The other engine was old even though she still runs great but smokey on start up. Some Duver 23's circa 2.6/3.2 tons in the water have been retro fitted with 100/120/150 hp engines and some achieve 25 knots.Not looking for that but 10knot cruise will be nice. I can live with the fuel as long as I can get to the more distant fishing mark 12/15 miles off shore .

It is definitely a 1.8 a lot smaller than the 2.5 that we took out.The gear box is a Borg Warner 1 to 1 Direct drive. This is what i was told by engine reconditioner The engine was originally a Police Van engine Normally 50hp but as it was for Police Leyland Sherpa Vans they where made to a 55hp specification.The marine fitter who is fitting the engine alerted me to the fact that it said on the Diesel Pump advertising on John Charnley,s web site Set at 30hp.It is transit to me as we speak.

Hi Looking for advice .I have had a pump purchased for me from the person I bought a recon engine from . Its a very long story and don't want to name names etc.
The pump purchased is a 62h260 CAV# 3247f181 and advert states for B.M.C 1.8 and set for 30hp CAV# 3247f181 Lucas Fuel setting A27E 1200-0-490 I have been told that the engine is a 1.8 but a 55hp ex Leyland Police Van Block....does the 30hp relate to Engine HP? will I get enough fuel it is a Sea Going Boat ....Can anyone shed some light please

Hi.I had a few pointers before re wiring of heater plugs. I had a relay.General opinion was why!!!It was on when I got it.I have removed it so turn on ignition hold key over away she goes But key is low I'm tall old an fat and cabin is Tight to say the least So awkward hold key in position. So I thought take wiring away from ignition on to a neon switch. Done all that but blowing fuse after fuse 15/20/25 amps .....I know put it back to how it was but just thought it would be easier I could also leave it on for 20 seconds after ignition to burn up excess .Can it be done?Cheers

Fit 3?
Don't know if this will show as in Rhodes at the moment. So update on PuffAlong.everything back as should be ,But talking to my mate tonight over dinner,He said I would have to fill up the Injection Pump with Oil!!!! Something I must admit I didn't know about.I this is correct fill to a level it run out of the loosened nut on top?,?also straight engine oil.Hope everyone's boats have weathered the storms I have been hearing about. I'm lucky I can view it on Torquay live web cam?

It is not quiet as simple as Sam implies. He is correct about just getting the splines in but the pump has slotted fixing holes and needs to be twisted on its mounts to set the injection timing. I think the 2.5 has a pointer on the block into which you slide the pump that you line up a line scribed on the pump flange BUT on a well used engine you really need to set that pointer before you fit the pump but that requires a special tool. Normally they run well enough as long as you align the line to the pointer but sometimes people twist the pump (with difficulty) on the running engine to get the engine sounding "right".
Will check it out thoroughly as getting a little spooked with it now.Annoying as I have gone far beyond what I thought I could do.But don't wan't to fall at the last fence...Time will Tell.

Reading this topic I assume the engine is some type of BMC. If so and if the pump is similar to the 1.8 the technique is as follows. Offer the pump up, push/feel it in, at the same time give it a gentle but firm twist anti-clockwise. It WILL glide home after a few tries. À few choice swear words are an option.
If it's not similar to 1.8 sorry to have wasted your time.
Frank
Hi Frank ...I have said all the swear words already!!! I Will try give your way a go........Does it have to be timed?....... I thought it was a straight exchange but I keep see Pumps on YouTube with viewing windows on them for timing them???????I realise that techknowledgey has moved on...... I presumed if the engine was rotated it would be OK or am I be a bit dumb?

Nope.You need @Boater Sam or @Tony Brooks
Hi.The Electric Drill solution worked (Thanks for the tip) I did up the chuck as tight as possible and constant heavyish pressure it came out 1/2 mins Brilliant I had visions of braking it.as a Tad Ham Fisted.I removed the fuel tank cleaned it out.a fair amount of sand/grit an black gunk say 2 level table spoons full.I have renewed heater plug.Fitted the refurbed injectors. Connected the spill rail.Just cant seem to line up spline on the refurbished injection pump to the casing.. Will YouTube it tonight for some ideas.No Videos on refitting pumps...So here is the question HOW DO YOU LOCATE THE SPLINE BACK INTO POSTION? It seems the engine has been turned but I know it hasn't.

Can you soak it in diesel or plusgas overnight? Heating it may also help.
I gave it another good belt of WD40 before i packed up.....It might help but not sure?...... I can move it back an forth 1" but it wont come out........Any ideas why the plugs got progressively harder to remove.

Indeed, or even a decent old fashioned garage. Assuming that you can reuse the nuts, all that's needed is some pipe, a hacksaw and a pipe flaring tool.

Getting there!! [I Think] Diesel Bob UK has refurbed my Rare Injection Pump My Rare Injectors, [which other C/World user had pointed that out already]he has got me 4 new glow plugs ,All Being Overnighted to me all for £420 including Vat.......Which seems to be cheap.Great Service.....Anyway I got 3 of the 4 glow plugs out but #4 is a **************** if you get my meaning......#I was easiest #2 slightly harder #3 was tuff but #4 wont budge out of it's seating.......It is totally unscrewed but carbon holding it back........Any ideas or hacks ......,I don't won't to break it.I have a video if it will upload. https://youtu.be/F9e590yVzwl

Have emailed ASAP will look elsewhere thanks for the advice
Diesel Bob UK don't list any pipes but was going down that road Monday just wanted to get things rolling as my daughter is with us from USA for 3 days and she wants to get out on the briny with her old Dad.

It should be a mechanically governed DPA pump, unlike the hydraulic ones on 1.5s that do hunt when fuel starts to get a bit short, so I would be more inclined to think about causes for fuel starvation that getting the pump overhauled. Anyway a decent FIE specialist should be able to pop ii on the test bench and check it out for far less than the overhaul price. I don't know how obliging your specialists are but if you ask nicely they might let you watch and explain what you are seeing.
When diesel "hunt" it is known as surging and "spasmodic engine beat" suggests to me something a bit more rapid than surging. Any chance you have a faulty injector that gets sticky as it warms up?
The whole thing is a bloody minefield!!!!!!!I will ask them to bench test it before they refurb.I did use them 25 years ago and they did a good job ,they are still today so they must be doing something right!

Fitted the new fuel pump works fine had to refit the lever mechanism as the original one didn't have one does but it does have a lever to prim but a bit hard to operate, but drilled another hole in lever to connect the priming arm to the push wire plunger from the other new one (the 2.5) this works fine now.But alas injection pump is still hunting and inducing a spasmodic engine beat.took her out just past harbour arm this morning it just started hunting ....This was after 30mins under load at 3/4 running speed in reverse securely tied to pontoon......So will send of pump to JC Isleworth to get it refurbished/replaced £325 but if it sorts it I will be happy.

Tony once again thank you so much for your wise words/information. Just off now to fit my new shiny fuel pump into to my 2 5 BMC Engine. Entering the cam in a upward motion.Cheers Nigel

Hi Sorry but me AGAIN!!!!!.The guy opposite me has gone away for 3 week holiday!!!!Just my luck.. Anyway I do have a quandary re what this engine is it does say 2500 on Raw Water header and on engine block ,The original fuel pump looks small but has functioned ok,I ordered a new one as had slight leak and all the screws where a bit shot, plus it did not have a manual lift .So £25/30 it was a no brainer. I offered it up a new one but at time of ordering thinking it was a 1.5 so 1.5 was what I ordered ,when i went to fit, it seemed the flange was not correct[I did not realize it was canted to one side] I put this down to it being a 1.5 so as i was now thinking it was a 2.5 pump i reordered, the new 2.5 turned up yesterday and that wont fit,its way to big. But now the old one is off i can see I the new 1.5 will fit after all,So I was confused before now I'm totally baffled. But in my mind the 2.5 would be a Bigger Pump as is one on right but that definitely won't fit......So will fit the new one same size as the one removed tomorrow. SO is it 2.5 or 1.5?????????????????

From memory so are the 2.2s. Both engines (2.2 & 2.5) are very similar with only minor obvious differences.
The boat moored directly in front of me is owned by a diesel engineer.He served his apprenticeship on BMC Engines.So he is now taking on my problems.[thank goodness] Thanks for everyone's help.

B.M.C 1.8 INJECTOR PUMP REPLACEMENT
in BMC
Posted
Hi Its a Semi Displacement. I don't expect it to get up on the plane but it did do 10.5 knts on Chart Plotter .This was with my Family on board but with just me it was 8.5knts That was with a very manky prop.It has been replaced as have shaft an all bearing etc.So it had a fair bit of cavitation when only 1 person onboard .Hoping it will be better ,with that? The 55hp is just what the seller told me .stating it was a ex Police Engine .
