    Default Perkins 4236 Diesel

    I am going to look at a LR which has a Perkins 4236 Diesel fitted.

    Does anyone have any experience with this engine?

    Is it easy to work on, part expensive etc.?

    Andy,
    Most 4236's these days are usually found in marine applications as they chug along all day.
    I take it it is a Series LandRover. We've had a couple of RangeRovers and a Series 2 Landie with Perkins engines in.
    One thing to bear in mind is that they are HEAVY and generally SLOW. This is partly down to the fact that they tend to run at low max revs (I think around 2600 rpm in some cases) which means you need to change diffs / transfer gears etc if you want to get decent speed out of them. If it is a Series LR this might not be so much of an issue but you may need to look at the brakes / springs to make sure they're OK with the extra weight.
    Having had a number of LR/RR's with engine conversions, they tend to work out to be more hassle than they're worth and a pain in the butt when you try to get spares, particularly stuff specific to the conversion (exhausts / clutch etc). For some reason, all of the ones we have seem to love leaking oil all over the drive as well !!
    IMO, Unless you have a real requirement for the extra torque, I would stick with standard.

    I don't know this particular engine, but if it is a marine engine it is best avoided. These are designed to operate at a fairly constant rpm, as opposed to the constantly changing rpm in a car or similar.

    Once upon a time people used marine diesels to put directly into trains, but the engines never lasted long due to speed fluctuations.

    As I said I don't know this engine so all I have just said may be utter cr*p.

    Thanks for the replies, it just confirms my thoughts.

    The vehicle is a Stage 1 109, bodywork in good condition, but with this Perkins Engine in, which apparently came out of a Range Rover.

    The price is right, but I think it will be more hassle than its worth.

    I have been on numerous sites for Perkins Diesel engines and can only find reference to marine usage of this unit.

    This engine was also popular in light earth moving equipment. I think one of ours came out of a bulldozer, hence all the torque!
    It was a popular engine conversion for range rovers in the 80's and 90's before LR introduced the VM and Tdi's.

    In the days before the Tdi, and the Japanese turbo-diesels of around the same time, the 4236 was just about the only alternative diesel fitted in Land Rovers. It was heavy and not particularly fast, but could tow heavy loads for ever and was very reliable over high mileages - which is what most people who fitted one wanted.

    The question is, with the engines that are available today, is it worth the hassle of purchasing one of these units, or paying a little more and having an original LR unit.

    My main concern would be parts availability/servicing etc. in the long term. I am not concerened about originality, as this vehicle is being purchased as a working vehicle, rather than recreational.

    Hey Andy,

    I have a Perkins 4203 unit in my SIII. Parts wise, there are a few specialists around the country that supply genuine Perkins parts. The Perkins website has a link to find distributers: http://www.perkins.com

    I have just done my first oil change and decided to try a local parts store for a replacement filter. They managed to find a filter approx. the same size, original intended for an automatic Mini?!? The filter housing seal is causing some annoyance tho, as the one supplied with the filter is too large - am thinking of resorting to silicon sealent until I can get hold of the correct one as the old one is leaking a little.

    On the whole, the engine pulls like a train off-road but is extremely noisey on the motorway. It's very economical, as it only revs to around 2,600rpm I've been told, but can hit 60mph when pushed - just make sure your wearing ear defenders! Also it makes a great talking point - the 4203 was originally designed to go in a Massey Fergusson tractor I've been told!?

    Hope this helps.

    Thanks Kyser.

    This does give cause for concern if basic service parts are difficult to come by.

    I have emailed some of the suppliers on the Perkins website to see if they can supply service parts.

    I have spoken to Hindles in Bradford and they were very helpful.

    It would appear that most of the internal parts are available, however some of the external parts may be difficult to come by, such as rocker covers, sumps, dips sticks, filters etc.. Without an engine number I am a little stuck.

    From what I was told many of the engines fitted in Land Rover/Range Rovers were manufactured in Spain (being painted red) and were supplied to Renault Trucks.

    If this engine is one of those Perkins do not supply parts, it would be Renault Trucks.

    Try agricultural dealers for spares. Perkins lumps can be found in virtually every machine used on farms.

    Bloody criminal changing the engine in a Stage 1. there wasn't that many of them in the first place. And as for putting a Perkins in a Range Rover, that's a decent vehicle ruined.
    A mate had an engine of this type in a S1 some years ago, and got fed up replacing clutches that were literally ripped apart bu the torque.
    I wonder how many miles the Perk has done then - this could be it's 3rd vehicle.
    If there wasn't petrol - I would pedal
