Possibly 1 for oldschool mechanics - Isuzu c201

[treepke]

Not sure if this should be here or in the boat section - mods please feel free to move if necessary.

In brief

I have just bought an old Dutch barge with an engine that is stamped on rocker and elsewhere "THERMO KING" Through goggling I am 99% certain it is a marinised Isuzu c201 engine but not 100%, it could be an earlier Mercedes or a later Yanmar.

Ran upriver under load for about5 hrs.. and very sweet it ran too - however it does have a drip from the waterpump and the pulley is very "flexible / wobbly"

Does anyone have, or know where I can get a parts manual as I am not having much luck locating one before I order a new pump,

Many thanks in advance....T

If it's still an original pump, it may have a manufacturers part number on it which would be more helpful.

Many thanks for the reply.......checked today...... definitely is a C201...couldn't make out the part No but this is definitely it: TB-37-11-4576 Pump water c201.... not managed just to find one outside of the USA yet.

Would be nice to locate a manual for it but not going to hold my breath.

At the end of the day, no big deal buying from the US if it's readily available.

Certainly google suggests it's cheap anyway.

But you'd think some boat repair/build type places may have sourcing options locally ?

Try the old yellow pages for such things ?

I just logged onto a yanmar dealer site for you and I can't find either a reference to the part number, or the C201 engine series (I guess c201 is the isuzu series). By the looks of it, it's a 1980ish engine? If you can find the yanmar engine series or part no for it I'll take another look....

Definitely the Isuzu c201 Matt..... as they were made specifically for TK I wondered if other Isuzu engines used the same part.

Found them listed in US sites but mostly "not in stock"

here's the blighter

Just fired off a few emails to US suppliers...fingers X'd one has stock.

If you can't get a new pump, the other alternative is to have a decent engineers install new bearings and seals in the existing one.

I recently had a couple of old ZF steering boxes (off E24 BMWs) refurbished by a proper old-school engineers near Brooklands (and a damned good job they did too)! Whilst I was there, I noticed they also appeared to be doing quite a bit of work on old marine engines. Don't know if they could help but maybe worth a try if you're stuck:

Ah, OK. I misread above that it was a yanmar based on an isuzu. (Like the yanmar 315 is actually a toyota engine)

This route looking increasingly likely....1 No and 2 No-replies so far.

[treepke]

looks very much like the same part to my untrained eye but can't find confirmation..anybody?

[MattYorke]

The lower RHS of the pump is completely different I'm afraid.

[treepke]

may have a result...in stock 75 USD delivered....so won't hammer the card too hard....fingers X'd

[treepke]

arrived this morning..... impressed I am

[stevieturbo]

Sounds like a good result indeed !

[treepke]

Don't know why I was getting so stressed about it lol

Silly Q I know but do I put sealant on gasket or sealant / loctite on bolts?

[PositronicRay]

It should be fine with just the gasket, if all the mating surfaces are clean and true.

But a bit of sealant gives a little extra peace of mind.

As for loctite...unless any bolt holes go into waterways I wouldnt be using a thread lock of any kind. I'd be using anti-seize compound of some sort.

Jobs a goodun.....many thanks for your inputs.

Next item on a Long list...reposition alternator so belt is not pulling at an angle!
