I have had a lot of trouble myself finding out exactly how you should tension the belt for Super 600 & Super 24 models, after working on one, and finding that I could not get it to output power correctly, at first i thought there was engine issues, but over a successive number of engines I found the exact same issue persisted, leading me to think I had the belt wrong.

I think I might well be able to get this Super 600 working now, and back to it's extremely patient owner who has been more than happy to wait and see how this all goes (One of our own, etal from Bega)

Even though I had tried a number of different tensions, it seems I was still doing it wrong, according to this, the bolt should not actually be pressing into the surrounding washer, so I'm going to try out this tensioning guide myself, and report back once I have the results!!

It may be a few weeks, as I am currently needing to move house again, but keep your eyes here if you want to know how this goes!

Here's the bulletin:

Well that may come in handy for me.Take up too much room for my collection.

hey.
thanks for this post it will be very handy with my fleet of super 24's
my 600 seems gutless its a standard full crank i installed on a 24 body, have just tonight given it a hone and new rings decomp rebuild and a high comp head. has a real pop to it now.
the tensioner "cup" and washer set up was missing when i got the body have coned washers back to back under the nut. i wonder if i have the belt to tight ? i tend to check tension with my thumb like at work on fan belts .

I can tell you too loose and it freakin hurts. I wouldnt reccomend that as a starting point.


I wonder if there is a sheet like that for the later model ones, I have one here with a PT on it and a 5hp quantum.

Cheers, Bob

Hi all,

RE: Belt Tension Super 600 Mower

On the Victa Super 600 mower if you DON'T have the V belt very tight (so it twangs like a guitar string) then it will slip and cause problems.

The engine normally turns CW to start, but it can start CCW (in reverse) and pull back the starter cord & damage the pull starter pulley (cracking it), and worst pull your fingers/hand back into the engine. This is because it needs to have the spinning motion (centripetal force) of the blades/blade holder plate in the right direction (CW) to start.

Hope this helps someone.

Hi all,

RE: Belt for Super 600 Mower

The correct genuine belt for the Victa Super 600 mower is a CH82248A (11M1150) 11mm x 7.1mm x 1150mm

I found a replacement belt nearly the same specs but cheaper.
I have just installed it, it�s a SPZ1140 (SPZ1140/LW) 10mm x 8mm x 1140mm, it will be interesting to see how long this belt lasts compared to the original one.

Hope this helps someone.

Hi all,

RE: Update on Belt for Super 600 Mower

The correct genuine belt for the Victa Super 600 mower is a CH82248A (11M1150) 11mm x 7.1mm x 1150mm

Just searching on the net, i see you can also buy a SPZ1150 10mm x 8mm x 1150mm which is closer to the correct size, i used the SPZ1140 belt because that was the closest belt size the local supplier had in stock.

Hope this helps someone.

This is what can happen if the drive belt is not tensioned correctly.
Be Careful !!

Hope this helps someone.

G'day John
Well that is news to me - that the engine can start CCW - and do this!
Great information to members for belt replacement and tensioning.

"Centripetal Force" should read "Moment of Inertia"

Hi all,

Finally got my old Victa Super 600 mower back together.

I had to replaced the Belt (correct tension of course), Complete starter assembly (second hand), Wheel bushes, Carby "O" ring, Blades, Air cleaner element, spark plug and repair the Snorkel, it now runs like a brand new one. All it needs is a coat of Red paint to finish it off.

Hello John

This is an important technical post for Super 24 and Super 600 belts.
I have renamed the post to include the metric '600'.

All the best.

Hi all,

RE: Victa Super 600 Belt Tensioning

Here is a copy of the correct procedure for Belt Tensioning on a Victa Super 600 mower.

Thanks mate. Much appreciated. Yours sure looks a whole lot better than mine.

I'm not having a lot of joy with Powertorques on these 24's for some reason. Took at least 6 pulls to get mine started today after it hadn't been started for 2 weeks. Once started it runs fine. To me the full cranks on these are much better.And if you don't get the belt tension right they could dislocate your fingers easily.

Hi Norm,

My PT 24 can be a bit snappy on the starter at times, usually only when flooded. Its not a real problem but we are a bit wary.

I'm sure the belt is not slipping. Its tensioned way up to at least to the Victa specs, judged by measuring the deflection at the midpoint. I no longer have the original tensioning system. Previous owner used big screwdrivers.

Sometimes I wonder if overtensioning might be an issue. If the belt is too tight perhaps it could make the mower hard to pull over, so you might not be able to get enough forward motion to keep things turning in the right direction. Its only got to stop just before TDC and then fall back to cause that problem. We compensate by giving it a decent pull.

I have been using automotive fan belts (11A section}. That's what was there but it was too long so I got a shorter one. The auto belts seem to fit well and are cheap. Genuine Victa belts are so expensive that they are not really an economic proposition ie more expensive than the whole mower. So are the blade discs.The automotive belts seem to last all right but could be part of a kick back problem I suppose.

All the best

Hi Jeff,
I have only played with 2 of these with PT's on them and I'm not impressed, the F/C ones are far better, none of the problems that the PT's have given me. The PT's have given me starting problems, I have tried 3 different motors on the yellow one and it is still problematic. The ones I seem to have most success with are the early full cranks that were fitted with the G3 carb and once I fit an LM to them they are great
