Yes.... I love the well groomed corporate mindset.

I picked up a Victa Power Torque Engine.


Formerly having no idea what the engine is, I looked up the Victa website, and tried to find out what it is, and their "technical drawings" section - it's as good as the scribblings on the back of a toilet door.

I emailed the factory with the crankcase numbers, 2 times, once off the web page and once via regular email.... no reply - nothing.

Anyway - so after this outstanding level of customer service....


I want to run this engine at LOW speed and LOW power...

I also want to run a V belt drive from it.

I want to mount the pulley on the crank shafts taper and standard connections (taper and nut).

So I think "Hmmm I want to get a pulley with the correct taper in the bore, so it will fit on, and stay on which inherently comes with having accurate parts that make a very high accuracy fit.

I figure that with some designs, that the easiest way to get the specs on the taper, is to ask the people who designed it.

I thought that phoning the factory, before going and getting gauge blocks, and accurate measuring equipment - and doing all the hard work - was the smart move - because it should have been much easier - and I don't have the equipment to measure the taper, in an absolutely accurate way.

I rang the "factory" in Siddey North South Wails, and spoke to a clever fellow in technical department.

I asked him, "What sort of taper is it?" - my question thickened with the adjunct "Is it a type of Morse taper or a "factory special"?."

He replied "I cannot tell you that, because you will go away and copy the design and make parts and sell them on us".

I thought "That's a good answer"



I asked to speak to his manager.

He refused to escalate the call.


I was impressed. In a rhetorical and inaccurate sense, to have a design that was made in 1973 - and has been out of production for years, and has sold some 30,000,000 units world wide - and given the fact that there are squillions of people in thousands and thousands of workshops all over the globe, that do, can and probably have figured out the taper in all of 3 minutes... that the guy in the technical dept - was in my opinion - an outstanding example of insightful creativity.

The Victa customer service - it's all terribly impressive.

With back up and support like this - you can be very sure I will buy a mower off them - you can count on that.


Anyway - so I would like to find out if anyone here knows what the exact type of taper is or it's specification, on the 160cc Victa Power Torque mower's crank shaft.

These are the engine numbers.

I just love it when you contact a company about one of their products and they tell you that they can't divulge the information because it's "proprietary" information! I sent an email to Samsung about one of their LightScribe drives and the information they sent me back came MONTHS after I asked it and not only that, it had absolutely NOTHING to do with what I had asked in the first place. I had figured out the problem on my own just a few days after I emailed them.

As for your engine problem, I'm sure if you measured the length of the beginning of the taper to the end, not the slanted part, then got the length of the slanted part and then measured it's height, you could use some trig to get the angle. I don't know the exact formula off the top of my head but I can get it later.

Shhhh.... I think I hear Russ's footsteps as he makes his way to his computer to answers your question. :arf:

Totally unavailable here in USA. I may have seen one once. I have done a search on them and come up with nothing.
No specs.
No diagrams.
No troubleshooting procedures.
Nothing.
Just the opposite is true with Briggs & Stratton, Tecumseh, Honda, etc. Info all over the place.
It's my understanding that Victa is suffering the same fate as the Lawn-Boy 2 cycle. Production is down due mainly to fears of these power plants contributing to global warming. This is crap.
Anyway, sorry I can't help.

Take a sideways pic of your shaft and post it if you can so we can show you what to measure.

hmmm victa ay.. i had a VERY old victa 2 stroke on my mini bike, way before the power-torque era. anyway it had a tapered & threaded shaft, and i have an old mate who has been a tool maker all his life who is VERY skilled on a lathe and he just truned me up a sleeve complete with matching taper & thread.. said would of cost about $300/$400 in a shop... got it for nothin'

if you could upload i may be able to help you.

HOWEVER, i did have a victa power torque engine that i was playing with. i didnt know where to look either so i took it down to my local mower shop.. he told me that you need to knock of the taper [do this by having a hammer on one side on the taped shaft and hitting it on the other side with another hammer; should just pop right off] And then make a new taper shaft to slip over AND be long enough to acompany a clutch/sprocket.
If your still confused TAKE SOME PICS and i will be able to explain it you more easily

Good Luck.

Victa crank taper

Well fellas i have seen two types of Max - Torque style of clutches on the Victa's on the Series 70 i have it has a straight 5/8" shaft no taper so it's not that hard to find on Ebay.com.

Yes and if you work out the taper on the tapered shaft crank let me know thanks
