I don't know if anyone picked up that he put the piston in wrong!!
Make sure the Victa is facing up on the conrod, also the locating ring tabs must face the inlet side / carburettor side.
Also I found using a 21mm open end spanner to remove the conrod bolt and a shifter to turn the spanner, locking pliers are too bulky and a pain to turn.
I would recommend a quick hone on all ring replacements.
If you do hone remember fast is better as it creates a vortex creating a perfect circle, going to slow will create a out of shape bore. If your going to go oversize like 20 or 40 thou always keep checking so you don't blow it. If you can it be better off getting it bored out at a workshop as honing that much out will give your cylinder too much slop.
I tried to go 20 thou but I found the inside has less wear than the front therefore its hard to get a perfect cylinder from a drill honing tool. The piston was fine at top dead centre but jammed in the back so I had to use electrical tape on the stone to get the back down without removing any more from the front.
All the best and PS I love these guys they are Awesome.
A large hose clamp will compress the piston rings.
large cable ties reversed so they release without the need to cut them off. No chance of damage.
Did it go or not
Seriously guys, give us a punchline. At least start it lol. Thoroughly enjoyed your video. A job I've done a couple of times and your way is better than mine, so I'm going to use your method from now on. Way less frustrating getting the rings in. Enjoyed watching it. Good work!
judging by the condition of the original piston shouldn't you at least hone the bore out?
very good motor had mine for almost 20 years still going strong.
You guys are great
Great video, I learned a lot watching it! Thanks for posting it.
Nice job
the piston Kit we sell suits both the Newer Type Power torque Engine and the earlier Full crank engines that have a removable cylinder, So should be universal for any 160cc Victa.
just curious why didn't you guys replace the needle bearing in the top part of the con rod? it will blitz the bottom end if she goes, not bashing you guys just curious that's all? Im sure there made better then they are now but I always replace them when I rebuild a top end..
Hi
We don't usually replace the top end bearing as they usually experience very little wear in comparison to the piston. after more then one piston change I would definitely recommend replacement or at the least a good inspection of the bearing just to be safe.
I have a tornado which has the longer blade boss. The engine is knackered, but I have another engine from a different machine with the shorter blade boss. Can I swap the shorter boss on the replacement engine, for the longer one I need that is on the knackered engine? Cheers folks 👍🏿
Well did the mower start after the rebuild ?
Yeah I was hoping for a one pull start!
Looks like you've got the ring end gaps facing the exhaust, does it matter which way they face?
The piston will work either way but Its probably best to face them the other way as the intake port is less likely to cause issues with the rings then the exhaust.
is there timing on a victa 2 stroke? mine is pull cord kickback and white puff of smoke from decompressor.. but i cant find anything on the internet about timing on a 2 stroke victa engine, only 4 stroke?
A little bit of a degreasing wouldn't hurt, first !
I always look for a tradesman who works off the floor and cleans everything prior to starting and during .. especially carburettors
Can someone help me with the orientation of the piston. I removed the piston to clean but at assembly I noticed that the indent at the gudgeon pin hole is off-centre. Which way must the piston be inserted with the larger offset towards the inlet or outlet port?
If Your engine looks the same as the one featured in this video then it is the Victa Powertorque Engine and the process should be the same or very similar.
This mower didn't look like it had done much work to warrant a new piston from use. Did the owner not mix oil through the petrol?
Yes that is most likely the reason this mower lacked compression.
No but it is the same bore and piston is the same all I wont
to no is if you have the right piston
I have a high arch mower is it the same
What size piston?
What about replacing the crankshaft seal??
Hi
The following video shows how to completely dis-assemble the engine so the crankshaft seal can be changed.

She will be an over reving Victa with a old seal!
Any idea where to get a spare aluminium pull start housing? Mine is broken, looks like previous owner got angry with it not starting.
If you contact us via the website contact form we can help you out with a housing
Ihope you clean BEFORE you replave pistons nowdays, watching the grime get dragged in on the rings and your fingers, then to hear sand grinding, just made my hair stand on end, like a blackboard with fingernails...yyyeeiicchh, read Zen and the art of MM ch 2.
what torque settings should i use for the head bolts?
the torque setting is 13.5-16Nm
PushMowerRepair.com would a hammer and a chissle work to remove the hold head gasket?
Use a razor blade to slice it off. Dont do anything that would leave a gash. Light wet n dry can remove anything left
michael phillips A freshly sharpened chisel or razor blade will do the job, I wouldn't use a hammer to much chance of damaging the surface.
