Couger gearbox

[NICK]

Can anyone give me some advice on rebuilding a shumacker couger gearbox. When i run the car the gearbox makes a clicking sound when on tarmac put is ok on sand / gravel. I am not used to this type of gearbox having built mostly planetray geared types. I have filled the diff with grease and i have the polished side of the thrust plates running on the ball bearings. No matter how tight i tighten the bolt behind the drive shaft the clicking continues.

any help

Have you checked the other gears in the gearbox for chipped, broken, missing or damaged teeth? another thing it could be, is the balls in the diff may have flat spots? have you checked them throughly to see if they are all perfectly spherical? if all the gears and diff balls seem OK, another thing you might want to check out are the Bearings? spur gear, motor pinion and especailly the Drive shafts? does it have the early telescopic UJ types or the later internal CV joints?

On some cars play in the outer axles can also make a noise? be sure to check all parts of the running gear for stiffness or play in the rotating componants? The clicking points to either a Slack or Tight spot somewhere in your transmission system, that only seems to appears when running under load?

Sounds like a Club 10 and not a Couger[?]

If it's a Club 10 then it is belt drive and not geared, the sound is the belt slipping over the diff, under high grip(tarmac) this clicking noise will happen if the belt is loose, all you need to do is adjust the eccentrics(round plastic things with about 15 holes in, where the drive shaft comes out). Undo the 4 small screws on each eccentric and turn the left-hand-side one anti-clockwise by 1 hole and the right-hand-side one clockwise by one hole, put the screws back in and try the car again. If it still clicks turn the eccentrics round another hole.

Hope this helps?[]

Agree with Jimbo, its the belt slipping. Adjust as Jimbo said, and back off the diff screw and adjust as necessary.

Jimbo, the car must be the first Cougar, with belt drive and the tea tray alloy chassis. The club 10 was based on the original Cougar, which was the Topcat with upright front shocks.

Topcat/Couger/Club10[?][][8)]

I m still finding out what the differences are between Schumacher's 4WD cars, before I start on their 2WD cars[:I] and just before you think you know them all this comes along[:I][]

[terry.sc]

I might still have my Cougar manual somewhere, if I can find it I'll check what it says about setting up the gearbox.

Jim, there are many more 2wd Schumacher cars than 4wd ones, when you include all the slight variations between each model. Its best to stick with the 4wds first. Dont remember the Procat SE though, looks like a Procat with Bosscat shocks and wheels.

many thanks from everyone for there advice, the car i was told was a couger, it does have a belt drive in the gearbox, it has no slipper clutch and a flat alloy chassis similar to the early nitro 10's. I have managed to rebuild it and amazingly schumacher who have been very helpfull still had an original couger body shell which was a direct fit. I will try moving the belt later this week.

adz,

Cat is mostly 4WD, although there was a version available in 2wd (according to my manual). Cougar is 2wd.

Maybe you should trade that gearbox in your spares box... to me... lol...

Nope, the CAT (Competition All Terrain) range of cars were all 4wd. The 2wd range started with the Topcat though, which later became the Cougar (a Topcat designed for the American market - they never got to grips with the Topcat laydown shocks)

I would check the gearbox you have is the same, most early Schumacher gearboxes looked similar.

For the lazer manual check my post in the Kyosho section. If you post pictures of the buggy stuff you have I'm sure we can identify what they came from.

Hate to be a pain in the butt terry.sc mate, but take a look at the cover of my Cat manual (http://www.tamiyaclub.com/showroom_model.a...id=21601&id=154) and you'll see a 2wd model number listed for the Cat. Also for you jamadz, you'll see I have a Cougar2 manual and a Club10 series manual - I can make a copy of any of these for you if you like.

Yeah, take some pics and put them up, I'm sure we can fight over who wants to trade with you []

The reason Schumacher sold a 2wd version (the same as PB sold a 2wd version of the Mustang) was a cheap way of getting an expensive (£199!) 4wd car - buy the 2wd version then add the front diff and driveshafts when you could afford them. It was never intended nor designed to be a 2wd car. I never saw one advertised apart from Schumachers initial adverts and press releases.

Interestingly the 4wd CAT led to a ban of front wheel drive in the 1/10 off road world championships. In 1986 at Romsey the ash surface had very little grip, so some Schumacher drivers, instead of using whichever 2wd cars they normally used, took the rear driveshafts out of their CATs and ran in front wheel drive. No rules were actually broken and the cars could not put the power down with the motor still in the back, but the cars were so much more stable and easier to drive front wheel drive cars were banned so teams did not have to have fwd and rwd cars depending on the surface.

sorry if i have started sommat here :/

but ill get some pics up and see if we can find out what it may be lol

pics on sunday

cheers adz

(in the middle of 2 projects at mo and getting confused over shumacher parts and kyosho parts lol

[Jimbo]

I've got some interesting pictures of modified 2WD Cats[]

Gearbox turned round so the motor was over the rear wheels[:0]

Bit more drastic this one, instead of moving the motor, they put 3 of the cells over the rear axle[xx(]
