I have been running on too much work and not enough sleep, 3 hours this morning after nightshift. Just slipped my mind. No excuse really. I won't be using the others now that I know what I did wrong. I'll have to get back into the bolt shop and get some new ones. What grade would these be? Share this post Link to post Share on other sites

Banno 479 Posted June 13, 2020 Take one of the bolts in they will match up correct bolt. What happen though? Over tension?Sent from my iPhone using Tapatalk Share this post Link to post Share on other sites

Banno 479 Posted June 13, 2020 Wow! I have been guilty of using old ones before in engines for quick turn around and never had a issue. Maybe I been lucky. I always check that the cap is sitting correctly before torque down and tap cap and tap crank back and forth to seat though. As said maybe I am lucky them times.Sent from my iPhone using Tapatalk 1 motoSycho reacted to this Share this post Link to post Share on other sites
motoSycho 690 Posted June 13, 2020 Got it out! I'll get new ones next week and have another go at getting it together when I can get another full day off. Share this post Link to post Share on other sites

bear351c 10,260 Posted June 13, 2020 Don't beat yourself up, mate. We've all done it. If you can afford it, grab some ARP or similar. Pretty sure they're Grade 8 high Tensile, but please don't quote me. 1 motoSycho reacted to this Share this post Link to post Share on other sites
FORD_MAN 1,026 Posted June 13, 2020 @DeanKDX SLY250 runs a modified XH crank, for new I'd look up Quickfuel 450 slayer vac sec, similar to holley but has more tuneable features like changeable air bleeds & rear jets, I have a Slayer 600 (VSF) on mine, 250 xflow has air flow requirement of 460ish cfm at 5500rpm, crank gear at 0° if not dialing in, surprised at the mains bolt breaking, Engine looks alright, good luck with the build. 3 gerg, deankxf and motoSycho reacted to this Share this post Link to post Share on other sites

gerg 10,871 Posted June 13, 2020 There shouldn't be anything wrong with using the old bolts. Only angle-torque bolts are single use (ie: E-series head bolts). Might have just had dud or one that had been over-tightened some time in the past Torque to yield should have a necked-down shank that's designed to stretch a certain amount.

motoSycho 690 Posted June 14, 2020 Bit wary of using the bolts that came with it now. They have probably been used a couple of times. I can pull the bolts out of one of my spare motors. I know they haven't been pulled apart before. 3 bear351c, deankxf and gerg reacted to this Share this post Link to post Share on other sites

I know they haven't been pulled apart before.During my apprenticeship (diesel mechanic), I did 4 months of work experience in a well-known engine reco place. I can tell you now, there wasn't anything that wasn't re-used unless it really needed replacement. Even tappets and rockers were re-ground and slapped back on. I never saw any bolts of any type being replaced with new ones, ever. Sent from my CPH1607 using Tapatalk 2 deankxf and motoSycho reacted to this Share this post Link to post Share on other sites

The Clevo in my XB has the original Mains, conrods and manifold bolts. 30 years old and been rebuilt 3 times. Only changed the head bolts 'cos they were rusty. 2 gerg and motoSycho reacted to this Share this post Link to post Share on other sites

motoSycho 690 Posted June 20, 2020 Finally managed to move from the manufacturing line I was on, with the amazingly crappy roster, to another part of the factory with a much better roster. I get 6 days off starting next Saturday, so will wait til then to put the motor back together, and then back into the ute. Got more parts coming, and stocked up on the oils and fluids I'll need as well. Lashed out. This Gilmer setup was cheap, so I grabbed it. 2 Thom and deankxf reacted to this Share this post Link to post Share on other sites

gerg 10,871 Posted June 20, 2020 Provided the power pistons and bores arent too worn, nothing much should go wrong with that carby.
