Engine stand and bolt size

Canada Nissan Automotive
1

I’m trying to mount my old SR20DET on an engine stand to rebuild it over the winter.

I need to know the exact bolt size and thread pitch of the bell housing bolts so I can go out and buy them, hopefully without going back and forth a million times to the hardware store :slight_smile:

The only other online googled result I could find was 12mm x 1.75 thread pitch.

Is this correct? Also, if anybody has any experiences with the Princess Auto engine stands, what bolt length seems to work best?

Is it true you need a couple nuts for 2 of the lower bolts?

I honestly did my best to find this info, but I found it very hard to get any specifics from other forums or Google, and did my best to search for this info here. A good link with the answers would be greatly appriciated if someone has a link to a ‘how to’.

Does this help?

and I’m pretty sure the bolts are 14mm . . .

Yeah, that helps a whole lot! Thanks.

It still dosen’t answer the question as to which bolt size and thread pitch I want.

So you’re pretty sure they’re 14mm threads? I wonder what thread pitch…

Man, if it wasn’t for the fact that my old transmission is still in my car, it would be easy to find out what bolts I needed!

I have a bare engine sans transmission or its bolts. I wonder if a tap and die kit would help… That way I could test fit the tap and see which threads I need.

Found on sr20forum.com. . .

Engine Stand Bolts?

. . .And 12 1.75 80 fit EXACTLY no washers or anything.

I still have that fourth free though need to get a bolt and nut to secure that one. . .

this what you’re looking for?

I can’t believe I didn’t see that the first time. But I was looking for a confirmation, and now I have it.

I bought 4 of these, grade 5, 12x1.75x80 and test thread them just now in the dark.

PS for all you guys out there searching your local hardware stores and not finding them, Triton fasteners at 41 ave and 19 st NE in Calgary had them and even though I was 1 minute after closing, helped me out anyways. They are one block across the street from Screaming Paintworks.

Thanks Lee.

Just to let you know next time just take your tranny bolt to the store, match a nut to it and you will know the thread pitch. Make sure you measured the length you need and now you have all the info you need.

Appreciate the advice Jason, but the whole issue here was that I didn’t have tranny bolts. The ones I have are in my working car and I didn’t want to take out one tranny bolt just to figure out what size I wanted.

Nissan wasn’t much help, because all they could tell me was a part #.

All I was looking for was some specs, and now that I have them it’s golden. :slight_smile:
