    According to Dave Ashcroft in the 50A-J and 53A-J the pinions are compatible?

    I'm not going to argue with Dave as he has all that information right at his fingertips. So I have been mistaken about the compatibility of the pinion shafts and sorry for that.
    Add info. After brushing up on my lack of knowledge, I found so far that those two type numbers ( 50A-J ( stumpy bell housing and 53A-J Short bell housing ) they have a reference to the layout type of the shift mechanism.
    Ref; http://www.ashcroft-transmissions.co...od&productId=6
    Ref; http://www.ashcroft-transmissions.co...atio_calc.html

    Different types of R 380
    The manual boxes can be categorised as "Long Stick" as fitted to the Defender and "Short Stick" as fitted to the Disco.
    If your serial number starts with any of the following then you have a longstick : 50A, 51A, 56A, 58A, 60A, 61A, 66A, 68A, 74A
    If your serial number starts with any of the following then you have a shortstick : 53A, 55A, 63A, 67A, 69A, 73A
    The longstick boxes come with the top casting that the gearlever and turret bolt to but you will need to remove the following from the old unit : the bellhousing and dowels, transfer case dowels, gearlever and turret and diff lock pivot bolt if fitted.

    The shortstick boxes come with remote top assembly with reverse switch fitted but you will need to swap over the bellhousing & dowels, transfer case dowels, extension gearstick and diff lock pivot bolt.
    The only exception to the above is the 64A and 65A, these come less bellhousing and less remote shifter.
    Ref; http://www.freewebs.com/tmtransmissions/

    Gearbox identification stamped on flat oval surface next to the drain bung.



    The first two numbers (prefix) denote the vehicle model application.
    The last letter (suffix) denotes the gearbox type.

    DISCOVERY CODES:
    Prefix 55 suffix G/H 200 TDI LT77. Prefix 55 suffix J 300 TDI R380. Prefix 59 suffix G/H V8 LT77. Prefix 73 suffix L TD5 R380.
    ---------
    DEFENDER CODES:
    Prefix 56 suffix G/H 200 TDI LT77. Prefix 56 suffix J 300 TDI R380. Prefix 68 suffix L TD5 R380.

    I will have a look amongst my books and see where I slipped up on the teeth counts though. still searching

    Hi Arthur

    I'll be very displeased if the V8 53A suff J box is not compatible, apart from the original purchase of the kit from Ben, I have now spent over $600 with Ashcrofts, and the purchase some years ago of the Disco box. I may have just as well dumped the suff J box and looked for a Suff K or L Defender box.

    Hi Arthur

    I don't know what you're pointing out as both the diesel and V8 pinions seem to have a 22 tooth count.

    I'm using the spiggot bush for the series the same one it turns out as used on the coil sprung 2.5 and tdi diesels. The flywheel will be the series flywheel, but the tdi200 clutch pressure plate and friction plate (130)

    Hi Diana

    A few post's back I said that I was mistaken about the tooth count, both V8 and Diesel input pinion shafts are 22 Teeth, the difference is in the tooth count of the clusters.
    The interesting thing there in those pictures is the gap between the gear and the end of the input pinion although I haven't found a picture of the 'L' suffix to compare the 'J' suffix with yet.

    I could take a photo of mine ( 'L' suffix ) but the process of displaying one photo on here is painfully slow for me using my card out of the Canon then downloading to a fresh folder on the laptop and then resizing the wanted file then attaching it to AULRO and then opening up the thumbnail to save as a URL on the post.

    Good plan , I take it that the 200 TDi pressure plate has the same hole placements as the hole pattern in a Series flywheel ?

    The spigot bush is the same part for all the engines from the 80" up to and including the TD5, except for the V8's, I haven't found out about the Puma engine yet.

    Is the spigot bush, the soul of the Land Rover?

    What does that say about the V8s?

    Yes the stud pattern for the clutch on the flywheels are the same, in fact the only thing that changes between the original and the later diaphragm type is that the diaphragm types have 3 dowels while the earlier one only 2 dowels.

    I have gone back to using your photo as that does show both gap sizes and the different width of the gears.

    Your photo.


    note the gap for the 'J' suffix shown here.

    The new J suffix pinion is due to be delivered tomorrow morning. I can measure that up tomorrow evening.

    The K/L suffix one will have to wait until the weekend.
