Dolmar PS 5105 piston options?

[half_full]

It seems the only piston I can find for the PS5105 is $70? Seems rather high.
Are there any other options? Aftermarket or any other saw that I could swap in?

That's cheap if it's OEM!! The only other option is a Vec piston if you can find one.
Best source @fordf150!!

Husky 51 or 353 45mm will work if you trim the shirts to OEM 5105 length.

Sorry for the delayed response. Too many projects... Would the 51 or 353 piston produce same squish? Is one better than the other?

 

[ncfarmboy]

Squish should be close to the same. No I don't think so pin to top of piston measures the same. Could be a couple thousandth diff due to manufacturing.
No I don't think one is better than the other. I haven't checked the VEC pistons from Northwood to see if any diff. The Northwoodsaw pistons are on sale now$19.XX. They were yesterday anyway.

Have no idea if it is a concern in this case but on a project I was working on. Found a piston from a different brand saw ( correct one NLA) all the dimensions were correct so I ordered one On arrival the ring stop pins were in different position & lined up ring ends with the ports Just an observation

 

[half_full]

thanks for the replies. I noticed that the Meteor piston for the 353 is also a fit for the 350. I have a few new cheap aftermarket 350 pistons that I'll do some measurements on. If they are a fit, I think I'll order the Meteor piston. I went to the Northwood site yesterday and today and the price is at $32. Since I'm not familiar with the VEC brand, I'll stick with the Meteor at the same price.

 

[ncfarmboy]

Ring pins on 51, 350, 353 are center of intake. Not an issue. VEC pistons are made in India IIRC.

Left to right... Dolmar 5105- Husky 51- Husky 353

Wanted to get a look see and comparison to see what can be done as an alternative.

 

[half_full]

Hey, your 5105 piston looks alot like the one I have...
Thanks for the pics!
Since it's not my saw, I'll order the 5105 piston and be done with it.

 

[ncfarmboy]

OEM 353 is single ring like 51. 45mm x 1.5.

I wanted to bring this back up and ask @ncfarmboy how he deals with the piston pin to crown height difference when using the husky pistons in the Dolmar. Hey Mike @half_full , did you end up using a Husky slug?

 

[Poleman]

After being told one of these would work I purchashed them to do/see. After getting them I didn't see any way possible......it died there for me.

I did the same Rich, and couldn't understand how that 3mm of difference could be made up. That's why I'm back. Thanks.
