The metal idlers on my Heng Long Jagdpanther simply screw in place. As a result they wobble around and throw tracks frequently.

I have bought a Hennetec track adjuster:

How do the wheels attach to it? My wheels don't have bushings. Will I need new idlers?

Steve

Crius

I had the same problem when I put a henntek in my King Tiger. I ended up having to buy new idlers.

maillemaker

Which idlers should I get?

Steve

Crius

You'll have to see what fits. Where did you get the henntec? ETO has idlers and I imagine Bob will know which ones you need.

maillemaker

I got it from Forge Bear.

Steve

Crius

That's for a Tamiya. I don't know if it works with a heng long tank. You better email Dave (Forgebear).

Dave is showing the Idlers for a Jagdpanther (Taigen) as out of stock these are on the same page as the "Henntek" Adjuster, If you go to ----
www.rctank.de
they are selling the Taigen Idlers as a set with sprockets, All metal with bearings for 24.95 Euros,
Be aware that Dom at rc tank will include VAT at 19% unless you clearly tell him you are not liable because you are in the USA.
I have not checked if Erik at IMEX has them in his Store in Florida it might be worth while talking with him.

No, I ordered the one for Heng Long. Gave the wrong link before. This is the one I actually ordered:

Hello Steve,
please send me your adress by mail or PM, I will send you 4mm axles.

Could you attach photo from your idler wheels here?

You do not have wrong idler wheels, but a plastic tub where only self-tapping screws hold.

Pulled my idler on my Heng Long metal upgrade tank today. Here you can see what I have to work with:





The screw evidently is a shoulder screw which is intended to provide a shaft for the wheel to ride on. But it is not a close fit and there is substantial play in the wheel which allows the tracks to jump on the idler.

So I assume this wheel will not do with the Hennetec axle?

Here is the Taigen "Jagdpanther" wheel, but it does not look correct in the picture - it has "3" stacked wheels not two:
PANTHER G & JAGDPANTHER METAL DRIVE WHEELS AND IDLER WHEELS SET

Maybe this one is what I need?

PANTHER G/F AUSF G METAL DRIVE & IDLER WHEEL SET

The latter appears to have some kind of bearing.

Also I assume I will be cutting away the plastic boss on the Heng Long hull?

You need to buy the idler set for the metal lower hull. They ise an axle with set screw like Tamiya does. The stock Heng Long junk uses a sheet metal screw to hold the in place LOL. The ones in the link appear to be right. Make sure they are for the metal lower hull and you are good.

maillemaker

So this is the one I need?

PANTHER G/F AUSF G METAL DRIVE & IDLER WHEEL SET

By the way, the Heng Long unit is not a sheet metal screw. It is a self-tapping shoulder screw.

Steve

yellowshaker

My Feedback: (1)

Yes that should do the trick.
And "sheet metal screw" was a just my attempt at humor. They should be using a fine thread screw going into metal. Plastic wears out and fatigues and cracks and...etc

maillemaker

Yup. I actually thought I would find a sheet metal screw, and was surprised to find they at least attempted to use a plastic-tapping shoulder screw!

Steve

maillemaker

OK I ordered the Taigen wheels.

I received my Hennetec axle.

The instructions are in German. Does anyone have instructions in English?

I used Google Translate and it looks decent but I'd prefer clear instructions if they are available. I emailed forgebear we'll see if they have some, too.

I found this thread here:

http://www.rcuniverse.com/forum/rc-t...r-install.html

With a translation.

It looks like to find the location of the main axle hole, after you grind away the original plastic mounting boss you position the main axle of the Henntec unit over the original hole location, and then rotate the swing arm to the 11 o'clock position. The hole from the swing arm thus becomes the drill point for the main Henntec axle unit.

Is this right?

Steve

maillemaker

I'm not sure I received the right axle, though it is labeled right. Mine does not have the big silver washer on it shown here:



Here is mine:


Steve

In this thread here you can see a guy doing a plastic HL Jagdpanther and see the big silver washer he had:

http://www.rcuniverse.com/forum/rc-t...l#post10077523

My kit does not have that. The instructions just show the main black housing on the outside of the tank hull, and the nuts on the inside.

Hi Steve,

be happy,because you have bought the updated tensioner. The tensoiner became an update 2016,forgebear had not updated his fotos in ebay.

The installing is with the updated version much more simple and the screws are bigger and more stable.

Have a look in my shop,there you can see the actual items.


regards,Guido

maillemaker

Hi Guido,
I was examining the item last night, and noticed that with the built-in flange on the outside of the tank, the height works out exactly to the height of the original plastic mounting boss. So I can see how it works without the backing washer.

Thanks!

I received my Taigen Jagdpanther G drive and idler wheel sets from Imex. The idlers are very nice with bearings and shaft pre-installed and they are nice and tight.

The drive wheels seem to match exactly. The idler wheels are slightly larger than the Heng Long originals. Did I get the right ones?

I suppose the slight size difference won't matter especially with the tension adjustment.

yellowshaker

My Feedback: (1)

Size won't matter in this case. One may be an early version, but not sure about that.

maillemaker

I've got a late-model Heng Long Jagdpanther.

Steve

So my installation of the Henntec tensioner is progressing along. I will make a full English write-up with pictures when I'm done. It is important to note that there are left and right main bushings. You want to install them so that their set screw is facing rearward so that it can be manipulated when the assembly is finished.

I can tell already that there is far less slop in the idler wheels than with the stock idler.

Two questions:

Does anyone know what size Allen wrench I need for the tiny set screw that holds the wheel and collar in place?

Also, does someone make a tiny nut driver for the screws that go through the hull? It's hard to get them tight with pliers. I know they do not have to be very tight but I don't want the nuts coming loose. I will probably put a drop of super glue on the shafts when done so they can't come off.

Steve
