I would definitely spring for new rings and give it a light hone whilst you have it apart - piston doesn't look that bad. I am quite sure the PT piston is backward compatible so if you have a spare.

That being said https://www.outdoorking-forum.com.au/engines...iston-assembly-en72843a-en70718a-150-077


You would pay $15 for just a standard set of rings - this way with a hone, new piston, gudgeon, rings and clips, you effectively have it all sorted. There is the issue with the bore wearing oval in the 160's but It doesn't look that worn out (judging by the body).

$36 is SFA in the scheme of things if you plan on keeping it for the long haul

And it only cost me $2 haha.

Got a Talon hedger, 2 whipper snippers, the ozito blower, 3 beach umbrellas, and 3 new in box umbrella bases for $20 - best deal I ever had at the tip
Had a tankful of water

Are you sure it doesn't say 1974 onwards? - I don't know of any 1984 blade change. Judging by your photos, the regular blades you fit to 18in PT engined mowers will fit - they are just standard Victa blades


With the grease, doesn't it have to be some 'brass safe' stuff? I dont know about grease - I just use penrite hi temp bearing grease in everything from kingpins to trimmer gearboxes and chainsaw tip sprockets. If I come across something that may need special grease, I look into it and get the right one.

I have ripped apart several 15-20 year old gearboxes of trimmers which don't have grease points - have to manually 'split the gear case'. Bolens/troybilt 31cc Brush cutters if you are wondering.

The grease was so dry it was cracked - and all flicked into the crevices away from the gears. Repacked with HTB grease and much quieter

Thats what they reckoned about my transmission - never need to change it. It was black and the magnetic sump plug had a 8mm coating of thick metallic mud. They also say 'oh, you must use the expensive SP3 Hyundai branded oil or your auto will blow up'. Well, in went 4L of Penrite Full synth Trans oil which 'Exceeds SP3 Mitsubishi and Hyundai'.

Shifts better than ever
