Default T55 in maintenance shop

Here are picks of a curious gearbox problem. I don't drive particularly rough but appears the axel got bent about the notch where the E-ring fastens.

If anyone has a T55 spare gearbox (left or right) or the fifth stage axel and gear pictured please PM me. Of course I would be glad to pay for the service!ox

The gearbox picture shows the removed damaged gear stage.

You are not the only one to be stung by those gearboxes. Even well lubed and oiled they fail.



I feel your pain Eric. How have you been pal?


The biggest issue with Hooben is the low quality of the RC components and durability. Their models are very detailed and are a good value. They are just not good runners out of the box. You really have to know what you are doing to overcome their numerous short comings. One of which are their TUs. They cut the grooves into the shafts so far for the "C clips" that the weaken the shafts structural integrity by at least 30%. I have fixed 3 of these TUs now for customers. only one was a T-55. Luckily for James when his Elefant did it at Danville the TU broke clean and the track spun freely rendering the tank unusable. It almost destroyed that gear but we were able to save it. I have no spares either Eric and made many parts by hand. As you can see from the fist pix oil & lube was NOT an issue. I was so unhappy with Hooben that I decided not to even build my Elefant kit. They are a good battle tank for occasional use. I just can't handle being a hard battler without major upgrades. I made covers with clear windows so we can check the TU shaft, gear and lube condition at any time.

Good Luck Eric I hope to see you at Danville this spring...March again?



For those of you building TU covers design and install the covers before you oil & lube the boxes or else then may not seal or adhere well. Oil the shafts/bearings first and work it in by hand while tilting the tank around. Then add the gear grease. I use white lithium since you can see it grow dark with wear and gauge its effectiveness. Seal the output shafts too with foam.

You lads need to do your forum searches. In my T 55 build I pointed out that Tamiya Pershing gears and final drives are a bolt in for the Hooben transmissions. With the added gear next to the motor, which by the way the Tamiya gears mate to flawlessly, the tank retains it's proper speeds without the Pershing external final drive reduction gears.

The gearbox picture shows the removed damaged gear stage.

Im using in my T55 tank standard Tamiya Tiger gearboxes with Jamara black long can 480 PRO motors and with Pershing final drive shaft (original Hooben final shaft is also possible) - working very nice. There is smaller wobbling /of the final drive shaft/ than with original Hobben gearboxes. In such situation no any extra reduction gear is needed.

Thanks for the replies and I am aware of the upgrades, it just was not worth pouring money into this Hooben model with all its flaws.

I would have to rebuild it completely!

But again if someone has chunked their T55 gearbox for a Tiger or pershing Tam box for instance, I would be interested in giving that old gearbox a home!

Same here...My guys were not happy with Hoobens antics. They just wanted them fixed, not rebuilt. If it were not for the fact the Hooben has great detail and make different armor than the other tank companies, they would be out of business already.

You didn't deal with them in a business sense as I did. I can't tell you how much I spent getting things fixed and replaced for customers amongst other things. In the end they finally made the 'shoot on sight' list and I absolutely refuse to have anything to do with them until Satan is driving a snow plow in his abode. It's a pity really, because the concept was good and they do build, or built, a couple AFV's that no one else made, but, like the finest cars in the world, without reliable service they are worth precisely zero. Therein is the problem, service, a concept Hooben has not a clue about.

That being said, there are no problems with the T 55 or Elefant that can't be overcome without too much work or money invested.

I've reading this thread with interest having a few Hooben kits myself. Other than the gearbox issue detailed here what are all the other faults?

Hi Eric,

I have 2 sets of all the original T-55 gears. We swapped out the Hooben for Tamiya. Let me know if you are still looking.

Any tamiya gearboxes (except the Pershing ones will work in the elefant. As previously stated you can use the Pershing gears in the t-55

Thanks, Tom I missed the bit about the Tamiya Pershing gear boxes being a direct replacement.

LOL I am glad you agree Bob. I know no one who has a Hooben as his main IR battle tank. They just can't handle the job.

However, the phrase "... there are no problems with the T 55 or Elefant that can't be overcome without too much work or money invested" is not something my customers want to hear after spending all that money on a kit and the time to build it.

Tamiya has set the bar very high in value, warranty, reliability, parts, durability, great detailed instructions....and most importantly QUALITY!!!

Are we spoiled or just asking too much ?

I agree completely, however, if you want a post war Sov piece the T 55 is it at the moment, rather a bit better than the other offering. And who else makes a viable Elefant at that price? Tamiya, we all know, is worlds better than anything else, no doubt. Still, with some work and some judicious modifications, the T 55 can and does survive this rock and mud garden called home as do ALL the Tamiya tanks. 'Nough said? My T 55 will end up with the KV/IS 2 Tamiya electronics and when finished will be a strong fighter. Now, got to get moving on the Leo 1 as an adversary!

The Pershing gear boxes are not a drop in replacement. The gear sets in the gear box is a drop in replacement. you need to dis assemble the boxes and swap out the gears. that is how it is done.

Hi Septon! So all you did was add the T-55 drive shafts to the Pershing gearboxes? Also did you have to make a mounting plate to adapt the gear boxes to the lower hull. Thanks, Rudy

Looks like some type of mod was done to the sprocket shafts from the picture, first time i had seen the Pershing boxes complete installed like that.
Would love to see what was done since i want to change the TU's in my T-55 to the Pershings. the only thing that held me up was the beleif that they needed to be completely interchanged.
