Title: Different sizes on 1.8t connecting rods? Post by: Terror_Flynn on May 03, 2023, 01:29:37 AM Hi
What are the different sizes on 1.8t connecting rods and which enginecodes uses which? I know about the small end diameter difference, 20mm vs 19mm But what about the width of the connecting rods? Title: Re: Different sizes on 1.8t connecting rods? Post by: fknbrkn on May 03, 2023, 01:42:42 AM Width?
Theyre same except of piston pin size that you mentioned Title: Re: Different sizes on 1.8t connecting rods? Post by: Terror_Flynn on May 03, 2023, 01:53:17 AM Are you really sure?
I'm a bit confused about the width. Some H-beam measures 24.95mm in width, with 20mm piston pin. And others just 19.95 in width. And tapered 19mm pin.

Title: Re: Different sizes on 1.8t connecting rods? Post by: Terror_Flynn on May 03, 2023, 02:37:48 AM Ah, so it is a manufacturing mistake, got it.
Sadly I have already bought those H-beam rods. So the rods are totally useless scrapmetal. Can those rods fit some other VAG engine? Maybe 1.4 TSI engine? Title: Re: Different sizes on 1.8t connecting rods? Post by: aef on May 04, 2023, 11:15:22 PM Interesting question
i made this mistake once but i didnt understand which engine does have the smaller width and why I dont see why the whole rod needs to be less width only because the piston/small end is smaller in width https://www.aliexpress.us/item/3256805058762926.html Center to center length: 144mm/5.67" Big end diameter: 50.6mm/1.992" Small end diameter: 19mm /0.748"( tapered small end) Big end width: 19.9mm /0.784" Small end width: 19.9mm/0.784" https://www.aliexpress.com/i/3256802968790662.html Center to center length: 144mm/≈5.66929 in.

Post by: Terror_Flynn on May 04, 2023, 11:33:06 PM Sadly I think quite a lot of people over the years have bought those H-beam rods.
Hopefully they notice the size difference fast, and they got their money back. Title: Re: Different sizes on 1.8t connecting rods? Post by: Terror_Flynn on May 06, 2023, 02:35:37 PM Difficult to source H-beam rods with tapered 19mm small end and 24.95 width.
I can only find those rods with wrong width measurements. Correct rods but with 20mm small end is easy to get. But I need to get new pistons with 20mm piston pins. |
