[VIC] Motor too tight to start.

[ari666]

run your jump lead directly to the starter motor (where the batt+ cable goes) and if it fires better then the battery cable to the starter has too much resistance.

if a full battery wont crank it there is some issues. lack of voltage at the starter, weak solenoid engagement, or maybe something inside the donk aint right.

You will only end up causing more grief for yourself e.g busted starter, busted electicals etc.

I still think you have not assembled the caps or rope seal correctly. Engines should never be so tight they can't be cranked after a rebuild. If they are there is a serious issue.

It's getting looser, I can get half a crank out of it now.

lol. sorry. but its lol. did you change the rings??? even brand spanker rings shouldnt be too much for a starter. i cant see how a pissy rope seal will cause enough friction to resist a starter.

This is rediculous, a motor (rebuilt, new, second hand, whatever) shouldn't be so tight that the starter motor can't turn it over (unless the starter is buggered). You need to pull it back out, tear it back down and fix whatever is wrong with it, because clearly something is wrong IMO. You either don't know how to do a rear main seal properly or one of the bearings is tight.

Seriously, fix it before you do some real damage.

I just recently put my 383 Chev together, it's tight, but it turns over with just a ratchet. That's with nearly 11:1 compression too by the way. That's with a neoprene seal, but a rope shouldn't be that much tighter if it's installed correctly. But it's also a brand new engine from top to bottom.

How many Kay's did the old one last ? A new rear main should not lock up a engine and all your doin is wearing it down so when ya engine does turn over it will just leak again.

but it turns over with just a ratchet.

lol, i need a breaker bar to turn fluffy starter works fine tho (when it engages)

 

[kingswood country]

I'm not entirely sure it was the rear main leaking, could've been sump, that was leaking, but I done it since the engine was out anyway, I can turn it with a breaker bar, but only just, I think I'm just gunna pull the bastard apart again.

i know it seems like a pain in arse to pull the engine out again but if you dont your just guna have a rooted engine. id say your big end bearings are in wrong possibly the locater is in the wrong place or it moved when you bolted the main caps down

 

[kingswood country]

A major pain on the arse, but I'm gunna start pulling it back out to see what's gone wrong.
