AW: 1985 Land Rover Santana 109 Super 5V 2.25 Diesel - Getriebeproblem???

Wir haben jetzt das Getriebe ausgebaut und es sieht nicht so super aus. Es ist Wasser eingedrungen und innen ordentlich angerostet. Ich werde es wohl austauschen muessen. Es ist ein LT85 solid case ohne Oelpumpe, laut meinem Mechaniker. Einzige Seriennummer ist I173. Wisst ihr, ob sich spanischen LT85 von den englischen unterscheiden? Die hiessen ja auch Santana gear boxes. Falls hier jemand mit einem Santana LR Serie 3A 109Super ist, der das weiss, waere ich fuer Info sehr dankbar. Wenn jemand ein passendes LT85 zum Verkauf hat, bin ich sehr interessiert. Danke erstmal.

Die lt85 Box wurde bei Santana gefertigt und für die Defender V8 nach UK importiert.
Schwachpunkt waren die Zylinderrollenlager, welche im Gegensatz zu den späteren Kegelrollenlagern keine seitliche Belastung abkonnen. Bei Fahrten langen mit hohen Geschwindigkeiten verreckte regelmäßig das Lager vom 5. Gang. Ein leichtes Singen ist als normal zu bezeichnen.
Was den Anschluß an den Santana Motor angeht, müsstest Du anhand der Teilenummern überprüfen , ob die Getriebeeingangswellen (Primary Pinion) identisch sind.
Der Anschluß ans LT230 sollte passen.




History

1984 through 1990When Rover (still part of British Leyland) decided to go to a five speed gearbox they picked the existingLT77 for use in certain vehicles. The LT77 is an updated version of an old Jaguar gearbox that found itsway into current model British cars manufactured by British Leyland. Yes the distance between the mainand lay shafts is 77 mm. There were two version of this gearbox. The earlier version is known as theshort stick version. The later version, introduced around 1988 is known as the long stick version.The Range Rover received the LT77 in 1984 because it was less expensive than the new LT85 andconsidered strong enough for the 3.5L V8 to use as a street cruising gearbox. The four cylinder Ninetyand One Ten also received the LT77. When the Discovery was introduced it got the LT77 as well.1984 through 1991The LT85 (85 mm shaft spacing) was used in all V8 110 and 90 Land Rovers. The LT85 was originallydesigned under contract by Land Rover for Santana in Spain and was considered to be a strong workinggearbox. Rover purchased LT85 gearboxes directly from Santana. It is also known as the Spanish Box.This gearbox was used as originally designed until 1988. A cost reduced, lighter weight, divided caseversion of the LT85 was introduced in 1988 and used through 1991. The main short coming of thedivided case version was its main and lay shaft bearings. The loading on the bearings in 5th gear causedfrequent gearbox failure when cruising for long periods of time under high throttle. There was also abearing quality problem at one stage of manufacture and the gearbox was sensitive to the type of oilused.In 1991 the relationship between Rover and Santana ended and the LT85 was no longer available toRover. They needed to find a quick short term solution while they developed a new stronger gearbox.1991 through 1993The LT77S was introduced to the Defender V8 line and all models using the Tdi engine as an interimreplacement for the no longer available LT85. The LT77S was a strengthened version of the LT77. The 'S'on the LT77S stands for 'Synchromesh'...it was modified for a 'smoother gear change'. The bell housingsand input shafts of the LT77S differ between the V8 and Tdi due to Tdi's more aft location.

http://www.expeditionlandrover.info/gearboxes.htmThe LT85 gearbox was used from 1984 to 1991 on 90/110s with V8s and 1986 on for Isuzu diesels. All of these boxes use a separate transfer case called the LT230 which is mounted directly onto the outputflange of the gearbox. This is normally referred to as the "Santana" gearbox as it was used on SantanaLand Rovers.

Ja, den Text habe ich gelesen. 1985 passt also zeitlich zu meiner nicht geteilten LT85. Darf ich deine Antwort so interpretieren, dass Du der Meinung bist, dass es Versionen mit solid case und versionen mit split case gibt, nicht jedoch Unterschiede zwischen den in England und den in Spanien verbauten? So wuerde ich es verstehen. Den letzten link kann ich nicht oeffnen.

Die 20C ist die HD Solid Box und die spätere 22c die Light Split Box.
Scheint, als seien die austauschbar.
Allerdings nicht die Wellen und Gangräder.
Synchoringe und Lager scheinen lt. Ashcroft identisch zu sein.

The heavy duty version is still being used for certain non-standard applications.The new gearbox, which is interchangeable with the heavy duty version, can be recognized by the prefix 22C before the serial number.The gearbox was first fitted from the following vehicle numbers:Land Rover 90 V8VIN SALLD VBV 7AA 299109Gearbox number 22C 00070Land Rover 110 V8VIN SALLD HAV 8BA 298614Gearbox number 22C 00061The individual gears and shafts are not, however, interchangeable between the two gearboxes"
