Engine re-build - Detroit - Desicion made - Start 03 Nov 2011

[Divemaster1]

hi all
sorry to get involved but i had to comment on this thread re removing the flybridge/saloon,it has been done before ..............Just thought you ought to know it is an option.
good luck with your engines

1) Really Appreciate contribution !!
2) Got space (and height) to lift out engine ... even with gearbox through sliding doors
3) Idea about this is to do it without lifting the engine (got piston and liner out already)
4) If I cannot get clamshell bearing on throug hatch in oilpan, worst thing I need to do is to drop the pan.... (but so many bl00dy bolts so wanting to avoid if possible) ...
5) Wanting to demonstrate that someone with limited mechanical knowledge could do a cylinder rebuild in situ (yet to be proven)
6) Old design, is not always bad design

And probably even more ..... whilst enjoying a very different part of boating experiences... and sharing learnings and knowledge, which I hope it achieves...

After a couple of weeks working flat out, I managed to contact dealer again ... Turns out that after measuring, the conrod is perfectly straight, with no damage, so that rules out hydro-locking and overfuelling (ref DD's engineer). Straight forward mechanical damage probably caused by broken piston ring at time of insert into piston or liner.

So new Piston, Rings, Bearings, Liner and Full set of Seals and some tools to help guiding the head straight on to block whilst on slant etc, is on order..... totalling approx £ 450, due to arrive next week ... in time for Christmas.... ... then it is back to trying to assemble the pieces again.... with accompanying photographs of course.

Thanks, need to keep my normal nimble shape to gain access to those awkward spaces ... don't you have a tank to attend to ?

Alf..I take it your foutain of parts and knowledge is Turner Diesels in Aberdeen.. They can fix these engines with their eyes shut as well as recondition parts as they do work for the oil rigs where these engines are used in many cranes.

Maybe you should find an out of work rig mechanic who loves breathing life into V-71's

Turner Diesel provides parts and some guidance.... Fountain of knowledge is my 860 page workshop manual and friends etc., who are Time Served DD Mechanics... The "hands on" I have done myself as I wanted to to prove to myself that I could do something like this myself, ..... but know that if needed I have plenty of experienced people whom I can call upon

Being mechanical engines, the are quite simple to work on, but you do need to follow the right sequence of events, as A, goes into B, that goes ito C and so on, and it is all very well described in the above mentioned manual... and they are inline 71's, more used as pumps and generators out there than in the cranes..

Any more progress Alf? I was enjoying this thread.

To be continued this coming week-end I hope as I have the parts , but work have kept me away from the boat I am afraid....

Giiis a break pal !!

Been cold up here and lying upside down in the engine room makes the kilt ride up all the time...

Wales ... where's that .... down in Englandshire somewhere??

Oh dear not a nice thought on a cold day

Wales ... where's that

It's a small province of England..... difficult to find and they arent on the Union Flag

You might have to travel back to Inverness and tow him down to Wales Tom...you know the Ford will do it!

That should put the pressure on him...

Surely it can't be regarded as a real contest without antipodean teams Kwacka?

Wishfull thinking after last year me thinks!

 

[Divemaster1]

For the people who doubt that progress is being made ... admittedly slow ...parts are here and ready to start assembly this WE...

Seems you got to Alf and shamed him into action Looks like the old clam crusher wont have to tow him down to Wales after all.

okay, got to google and find diagrams of how these 2stroke diesels work as this piston and liner make no sense to me... Piston tooooo long, liner holed in the middle
oh, good luck and looking forward to the pics!
