Old SV new idler gears, bad fit?

[hansie]

Hello all,

I own a first generation Cougar SV.
I received the new plastic transmission casings from
Schumacher after the first ones turned out to be crap.
Excellent service from Shuey by the way.
Now recently it was time to replace the idlers.
I got a note from my supplier that there were new items
then the ones I ordered from my manual.
The idler with shaft is now a single piece CNC alu version.
And the other idler was alu and is now plastic.
Fine by me, after I received them I bolted them right in
according to the included instructions and .,......... A terrible
tight spot. i mean really really bad.
I cleaned everything before I started the assembly, I checked the bearings etc etc.
Can anyone tell me how this went wrong?

Greetings

Hans

sv2 manual says they will be tight untill been run..... maybe same with yours

SV manual also said this, mentioning a tight spot but will run in within a couple of races.

How bad is it? does it feel like it will be improved by running it?

Hello all,

Thanks for the comments so far, to answer how bad it is.
If I want to turn the gears by hand I need to install all the gears including the spur. Only then can I rotate the gears by rotating the spur.
If i just put the 2 idlers in and I try to turn the Shaft that comes out
of the CNC idler, I need a plier to get past the tight spot.
When everything is assembled I can rotate the gears fully but I feel
heavy resistance. I think my motor will run through it but it will run hot
I think.
I might just give it a go on the bench without wheels and keep my eye on the temperature and see if it frees up.......

good plan, if it's going to free up it wont take long ;-)

Hello all,

On the bench the gears freed up.
After a while bolted on some wheels and took it to
the track. It runs nicely now after a few packs that were noisy.
Freeing the gears up took it's toll on the side gears though.
They were brand new as well and the plastic one is pretty worn
now, could that be because of the added strain of the tight spot?
