Crank pulley bolt

tahu · Post by **tahu** » Wed Jun 24, 2015 4:55 pm

so i finally got round to building my engine, and as it turns out the h22a crank shaft pulley bolt is a smaller size compared to the h22a5 bolt that i have.

Does anyone happen to have the h22a crank pulley bolt?

i really need one and im finding it very difficult to find one to buy due to it being an import engine.

Or if people have suggestions of how i can get round this i know i could find another generic bolt but i dont want to risk it seeing as it is such a highly torqued bolt.

Thanks

It should be the same size. I have never heard of anyone saying any different.

Why have I never heard of this before?

There is a few threads from the US that talk of different pulley bolt sizes http://honda-tech.com/honda-prelude-4/h ... t-2578284/

14X33 and 16X49

The 14X33's part number is apparently 90017-PT0-003 while the 16X49 is 90017-RJA-003.

Where ever it was it passed me by

Like I said I have never heard of this before. I would have thought it would have been more of a common issue. Anyway, rep+ for you

It isn't a 5th gen thing. The H22a2 (UK 4th gen) and H22a8 (UK 99+ 5th gen) crank bolts are the same (16X49).

Is it a JDM 4th gen thing? The JDM Type-S uses the same 16X49 as the UK engines.
