V160 total Stripdown + refurb Parts / seals


Andy Ven

Recommended Posts

Evening all,

 

I have started to strip down my v160 gearbox so that it can all be checked and worn parts replaced.

 

Does anyone know of a full parts list for the gearbox?

 

I have removed an internal seal which seems to be a special made seal. Nothing like i have seen before.

 

Has anyone else had their v160 or v161 apart and managed to source this seal?

 

 

Any help is much appreciated.

 

Thanks Andy

Unless something has changed, you cannot buy any gearbox spares from Toyota anymore, as Getrag have stopped supporting the gearbox and supplying parts. From what I gather, the last stock was bought by Jack's Transmissions in the US.

 

Jacks transmissions and Arnouts 'Suprasport' are the only companies around with any parts for these gearboxes, and I don't believe that Jack's will supply parts - they only do rebuilds themselves.

 

You may have more luck investigating how the R34 GTR tuners and owners are getting around these problems, as those cars have effectively the same gearbox.

I'm surprised you've stripped it down considering everyone also mentioned on your other thread, spare parts are no longer available commercially or otherwise.

 

I hope you find some in this situation mate. Not sure I'd have the balls to take it apart for a rebuild with no spare bits.

I would rather strip it and find out that most of it is ok than leave it and find out its a hand grenade in a few months time.

 

So far, everything looks pristine. Believe it or not, the oil which came out looked like it had just been poured out of the bottle, it was that clear.

 

The consumable parts (seals, bearings etc) at a push can be re-manufactured. Its just how much you are willing to pay.

 

I knew that the gears are unsourceable; so if there was an issue, i would have just split the box for spares.

Batch number/serial number maybe?

 

Looks like it has been done after it left the factory. Its too non-uniform to be done oem.

 

It has stamps on the shaft from when it was made with what looks like a batch code etc. Will have been done before it was hardened.

You are right. They probably arnt that difficult to make. The synchros are already being replicated and reproduced by synchrotech.

 

To make the gears though, you want a brand new set, which have no wear so you know the size and tolerance. Making some off Second hand gears could be a recipe for a noisy box.

 

I suppose its the cost and time to make say ‘50

Units’. How many people would be willing to buy them? And i suppose if a 1000 of each gear was made. The cost would be less but chances of people wanting them is slim now that other gearbox’s are more on offer.

 

 

I have stripped mine now and everything seems to be bang on bar a small bit of wear on the 4th gear synchro which is mounted to the 4th gear itself.

Toyota still has most of the bearings for the V160, gears and synchros are sold out though. I recently did the front input shaft bearing in one, and front and output shaft seal. Parts all from Toyota.

Also i have all synchro's lying from Syncrotech for another V160 i'm soon to be changing for a mates box.

 

So the V160 game is not all dead.

In worst case, bearings and seals should be possible to get from a bearing shop. I know that a lot of the tractor mechanics get their special bearings from those.
