cat 2000 ec project
 

Im looking for some advice regarding my cat 2000 ec. Recently picked up a rolling chassis very cheap and looking to use a lipo set up in it. Has anyone got any experience of using lipos in an ec? will it take a shorty or a saddle pack?
I also need to find out what lipo tray it will need.
The buggy is going be used as a runner so any advice regarding essential upgrades would be appreciated.
At present it only has plastic shocks. Is this normal for an ec or have rhese been replaced?
It also appears to be running blade drive shafts and not rollers
Love the look of the ec cant wait run it

I run saddle packs in mine, uses some AE carbon locators and KF straps and posts, if I remember correctly - very tight for space though. Should have dark greeny grey anodised pro shocks on it.

yeh i thought they might have been cheaper plastic shocks that were put on. ill replace them at some point. yeh it does look tight for space, going use top deck for spektrum rx so that should save a bit of space. have you got a code for the ae locators or kf straps? thanks

Just use b44.2 trays and carbon bars. Fits standard holes fine

great stuff thanks for that

I made my own
used some 3mm hex standoffs (easily found on ebay ) and sst /cat 3000 straps easy to make your own too


regards dave

ec rollers driveshafts should have the plastic shocks

ecs the special with blades should have the greygreen anodized ones....

looks like mine might be a bit of a mix then

Tried the b44.2 trays. holes are no where near close to fitting

The b44.2 trays do fit, however you do have to squeeze them a bit to make them fit.


Cheers Mitch

Oh I see. I thought they had to line up straight and not squeezed in. Thanks

I wonder if you might have an SE, as that had plastic shocks and blade driveshafts.

I did like Dave did, make up some bits to fit them, I used saddle pack lipo's.

finally got around to sorting out lipo trays and thanks to the folks who posted advice its looking good.
Ive noticed a major problem with the buggy though. with no electrics in it rolls nice and smooth as it should but when i put my motor in the car judders and struggles to move. i tried the esc and motor in another car so no problem with the electrics. The mesh wasnt tight but I have no idea whats going on. It struggles to move forward at all. Any ideas?

Have to watch the type of motor screws used and pinion as all close to the rear belt. Sounds like if you used cap screws it was jamming up

ec
 

yeh i thought it was the motor screws at first but i used small round headed screws making sure they dont catch the rear belt. the belt tensions arent too tight. not got a clue whats going on

Are you using brushless ??? Some motors are notchy don't feel smooth. Just the way they are

ec
 

yeh its a brushless. put same motor in different car with no issues at all though. even with throttle fully open it was just not moving

Screws too long and locking the armature? With the motor in and gear on does it roll? Can you spin the drive chain?

ec
 

screws arent too long its the same im using when swapping the motor with another buggy. when trying to turn the wheels by hand it feels stiff but when applying throttle the buggy hardly moves. theres a clicking noise when i roll the buggy with no motor in

Take motor out again see if drivetrain rotes freely as suggested by Kev B if you can move spur gear round easily and wheels spin it has to be linked to motor

dave

Had one thought, could be something locking the rear diff, You have to watch the 2 screws at the rear that hold the undertray and rear suspension bracket dont go through the motor mount and lock the rear diff and belt.

finally sorted transmission issues. only problem is my buggy has the blade driveshafts, one is damaged and seem impossible to find new. any ideas if there are alternatives, must be something else that will fit. the thread is knackered on a rear

I have some brand new rear blades on packet and the later cvd ones for a Cat ec/98. Also have some used rears I could sell

Brilliant let me know how much you want for them, used and new. Thanks!!

If anyone can help me out with a rear blade driveshaft it would be much appreciated!!

Sent a pm for you. Have rear u2213 CVD nip £60, blade rears u1915 £35,

Hi thanks but bit too pricey for me thanks

Thats the old rrp price on them but pm me if you want to make an offer on either of them. both are brand new in packets.

if youve got a pair of used rear blades id be intereted. just want get buggy up and running so i can put it on ebay. Not a massive fan of the 2000 to be honest

Rebuilding the diffs now. Using the co axial shafts. At the moment the diffs feel really knotchy.
Does any one know what pro thrust races fit or where to get them from? Thanks

Im sure rc bearings do them ihave had metric and imperial thrust bearings from them in past
top company to deal with

really struggling find thrust races for slipper clutch and co axial diffs, anyone help or advise???? please!!

Still on the Schumacher site

That size does not fit the slipper layshaft. they are ok for the diff though. Anyone know where i can get a slipper thrust bearing?

The part number was U730. The problem is that this part number has changed many times over the years, so it's going to be pretty difficult to be sure you get the right one.

Anyone got a spare front belt tensioner they would sell? Ideally looking for 2 but 1 would be great. Thanks

I suspect most people threw them away! No one ran it back in the day.

Does it have much effect or benefit running the tensioner?

last parts needed to complete total rebuild of my ec. Front bumper
Im looking for 2 x front bumpers. Must be either new or as near as possible. Might be a long shot but worth a try

Have two new in packet plus load s of good used ones
