olie kering Intermediate shaft tussenbak def puma

[vandestraatweg]

Collega klussers, Ik wil de olie kering van de intermediate shaft (tussenbak) vervangen. Nu staat het volgende in de handleiding.
Wie weet wat "end float" betekend en hoe je de gear bearing pre-load kan meten zonder tool??

11. Tighten intermediate shaft nut in small stages
until all end-float is removed from intermediate gears.
CAUTION: Check end-float of intermediate gears between each stage, do not continue tightening nut after end-float is
removed. Do not stake nut at this stage.
12. Set intermediate gear bearing pre-load-See Intermediate gear bearing pre-load.

Is er een manier om dit op het gevoel te doen (ik heb wel een momentsleutel). of moet ik me hier niet druk om maken?

Ok Johan,

If you look at the LT230QRS Overhaul Manual then the pre-load setting of the bearing sounds quite complex:

1. Select neutral.
2. Screw a suitable bolt into tapped hole in end of tool LRT-41-005.
3. Insert tool LRT-41-005 in end of mainshaft.
4. Using a suitable torque meter on tool LRT-41-005, check and record torque to turn mainshaft input gears.
5. Tighten the intermediate shaft nut in small stages checking the torque to turn the input gears until the mainshaft input gear torque to turn figure recorded in operation 4 has increased by 1.25 Nm (10 lbf.in).

So in real terms you have to turn the mainshaft using a rotational torque meter ... yes we all have one of those, and then when thhe torque increases by 1.25Nm tap the side of the intermediate shaft nut.

Now I'm no scientist but I think we can safely say that in the wild it would be quite possible to rotate the main shaft, tighten the intermediate shaft ever so slightly, rotate again and so forth until you just feel a very slight resistance on the mainshaft, Job Done.

Now the purists will probably have me burn in hell for that explanation but I bet none of them have ever done it with LRT-41-005 and a rotational torque meter either (I have)

Oh and the special tool for getting the oil seal in ... I like to call it a rubber hammer with a very light touch on the edge of the seal

Rob Super, de oilseal zit er nu perfect in (tweede want de eerste sloeg ik er te snel in en daardoor werd er een stuk rubber van het nieuwe ringetje afgesneden ; -( Gelukkig had ik er twee besteld!

De end float is eruit en nu ga ik het uitvoeren zoals je hebt beschreven! Met veel gevoel dus!

Ik ga me snel omkleden en dan de garage in!

Mocht je ooit in Rwanda komen, dan koop ik een biertje voor je!

Thx Johan
