Technical: Isuzu 42 Servicing Info

Posted by indigodream on 8 January, 2013

This is my reference page for the parts I regularly need for servicing the engine and also somewhere for me to store copies of the engine manuals etc.

I used to buy filters from a motor factor in Croydon which has now closed ūüė¶ so some of the references are tied into their references. Nowadays I tend to buy genuine parts from Kings Lock Chandlery (they do online also) and OEMs from inline filters – links below.

These are my parts lists:

Air Filter:  Isuzu Part No. 100066-4LS OEM References:  FRA CA5315 or Cooper AG 294,  An equivalent seems to be a Reisse 46100020.

Supplementary Fuel Filter:  FRA C1191PL or FDE-HDF296, I fancy the second is better?

Main Fuel Filter:  The manual say Isuzu Part No. 897172-5491. Last time my engine was serviced it was by the excellent Neil Coventry he put in an Isuzu 5876100220 so I suspect that the part number has changed. Finding an OEM equivalent is interesting.

Main Fuel Filter OEM References:either Baldwin BF954 or Donaldson P553240 or Fleetguard FF5030, Filtron PP944 or Mahle KC5. Note these are all a fraction longer then the Isuzu part so slightly more awkward to remove with my style of filter wrench.  This site cross references the Isuzu 8971725491 with an Isuzu 8941329471 and that in turns leads to a Fleetguard FF5394 which is shorter, same length as the Isuzu so I have ordered one, look out for us anchoring somewhere. Update: The FF5394 looks almost exactly like the Isuzu filter, works well, no issues so far. Note to self: I have photos to post.

Oil Filter Isuzu Part No. 894456-7412 OEM References: FRA PH6811 Mahle OC205

Correct oil is 15W40 CC grade which can be hard to get hold of. Supermarkets sometimes have it, motor factors often have Comma 20W50 CC Engine Oil, can be really cheap or there is an excellent Morris oil best bought from that lovely garage in Wheaton Ashton.

Chandleries stock genuine Isuzu parts but take care, the genuine parts are always expensive but not all chandleries are the same – did not note down prices but I think Kings Lock in Middlewich had pretty competitive prices for Isuzu branded spare parts (and they are nice people). Hint: When shopping in a chandlery just cover your eyes as you put in the PIN number, puts the shock off for a month or so.

My last shop from inline filters in April 2016 had these prices:

2 ea. FFR-CA5315 FILTER-Air(Round) £8.66 (£4.33 each)
1 ea. FDE-HDF296 FILTER-Fuel(Can Type) £3.53
1 ea. FBW-B1425 FILTER-Lube(Spin On) £7.12
1 ea. FFG-FF5394 FILTER-Brand Specific(Fleetguard) £5.00

I should start a list of useful web sites if only so I don’t have to resort to google when I can’t quite remember them. I will add more later but whilst I think about it here are two:
Useful site for odd Isuzu Parts:http://www.quayworks.com/
If you have any useful sites to add or part numbers for obscure things eg starter solenoids please do post a comment.

    Yes but what about Beta parts. The Fram parts from Midland Chandlers are equally pricey and there must be cheaper generic alternatives.

    No idea! Send me your parts list and next time I am in there I will leave it with them and get them to look up alternatives and a price, I think they do mail order? Otherwise I think Joe on Yarwood has been into a car parts place somewhere on his travels and may be worth talking to as I think he got an amazingly good deal for Beta filters.

    I use Baldwin (http://www.baldwinfilter.com/) there is a good comparison search, simply type in what you have & their alternative is then shown.

    Hi there what is the largest size prop I can put on my boat I’ve got a Isuzu 42 with a prm 150 gearbox many thanks Andy

  6. indigodream said

    Hi Andy

    We have an 18×12 driven by the same gearbox and engine as yours and really happy with the combination. We can’t get any more than 2000 rpm so I think that is as big a prop as we could have. If you are thinking that you want a larger prop then check the clearance to your counter first.

    Hi iv`e got a leaking injector pump on a 4lc1 any one know the generic part no of this pump.

    Oh font of all knowledge….it appears I need a new stop solenoid…have you any idea what the part number is?…I can get someone to come and change it for me…but obviously I need to order one first. HELP…many thanks..your site is brilliant for a boater with no manual or knowledge! Liz

  9. indigodream said

    Hmm worrying that you need a new stop solenoid, seems that you are not the only one! I asked the real font of knowledge, Neil Coventry, who texted me that the last one he got was from EnginesPlus and cost a fortune, much cheaper to fit a stop cable! Some else has written about being quoted £400.

    The only thing I have seen worth trying (other than a main dealer) is a company called JGsupplies Tel: 07976 960921 but I was a bit thrown as the website is something else Рworth a phone call as the quote a cost of £60 BUT not an original part. Also try Quayworks as the link above. Please leave a comment if you get anywhere.

    This is how I got there:

    There is a thread about stop solenoids on CWF here: http://www.canalworld.net/forums/index.php?showtopic=25327&page=2 which is useful but also confusing. Someone reports the part number as MV1-77 897209-1140. This tallies with the number in the HMI manual so seems right. When I googled for Isuzu 4LC1 solenoid I got a different number. That said there is also a useful link to this ebay page: http://www.ebay.co.uk/itm/Fuel-Shutoff-Solenoid-Replaces-8973295680-for-Isuzu-3LD1-3LD2-4LE1-3LB1-4LB1-/371774994363?hash=item568f8437bb:g:4FkAAOSwS7hXAlQj which gives the same number as my googling but it is an MV1-81, is it the same, no idea but as there is a phone number in the UK I think it is worth a call.

    Sorry I can’t be of any more help.
