crank & rod bolts reusable?
 

Got all the parts for a complete 1.6 rebuild, new pistons and some ARP head studs and even a new crank pulley bolt but i totally forgot about the rod and crank bolts :facepalm:

I tried looking around for some answers but none.

So are the crank and rod bolts reusable?

1. Why are you building a motor with stock rods
2. don't re-use the rod bolts
3. re-use the mains

I replacedal hardware due to the wonderful world of cost/benefit. $100 for new main bolts could help me drive home from the track.

1. im not boosting past 12, if anything im very satisfied with what i have now,10psi.

2.^^^

3. so main/crank bolts are reusable?

Honestly I wouldn't use those stock rods either, but yeah.. You can reuse the rod bolts and the main bolts. I wouldn't recommend reusing the crank snout bolt however.

Wouldn't kill ya to get some ARP rod bolts though.. ;)

jeez crist man, 300 bucks and it will be pretty damm strong. Screw the stock rods, wait another paycheck and get them. Even at 10-12 psi it something you should consider.

yeah i know, stock rods are no no, but i drove like 4hrs to pick up a complete 1.6 rebuild kit a few months ago and the dude had the pistons press fitted and mounted so cant get new rods.

The next motor i have sitting in the garage will be fully built in a fewwwww months but i need a fresh for now, my current is really old and shady

There is no possible excuse for using stock rods in a motor build. None. I don't care if God himself installed them. You take them out, get Belfabs, and put them in. It's retarded not to.

you're gonna end up spending more money if you take this route...

If you can tell me that i can remove the PRESS FITTED mounting pins with out damaging the pistons then I promise I will go into credit card debit just so I can order the m-tuned rods tonight

Granted, I've never built a Miata engine, but from the ones I have done, I don't recall the wrist pin ever being an interference fit into the piston. At least give it a shot. Remove the clips and try tapping the wrist pin out of the piston with a dowel.

If the pin was press fit the build wasn't done properly. Often times the pin must be polished down to the correct clearances.

sorry guys i cant risk "trying" to remove the pins if i dont got the facts that i can for sure.

If it was press fitted did they use circlips or not?

Edit: I am familiar with press fitting wrist pins on rods but never on pistons. Anybody?

Edit Edit: You have the motor apart and all of the machining done and don't want to use forged rods because you don't want to wait just a little longer?

Order rods, take them to machine shop, Give them 40$ and pickup in one day... ;)

im only assuming that the wrist pins are press fitted and then cir-clips go on each end?

If i can remove the wrist pins with out damaging the pistons i,ll order the m-tuned rods today. :giggle:

Pretty sure the wrist pins aren't press-fitted in OEM pistons, so either you're going to install fucked-up OEM stuff or you're going to buy Belfab rods and do it right.

Lemme tear apart this other block i have and check to see if the wrist pins are removable

Its not like re-using syringes with lizards at the truck stop.

ok, all done with the tear down. I checked the wrist pins and they come out like nothing after you remove the cir-clips...doh.

im ordering the M-tuned rods and some ARP main bolts right now.

we were just fucking with you dude, run the stock rods.
