Re: Oil not getting to right cylinder head

Hang on, hang on--people, come back here...
"...they failed to drill the oil passage in the bearing for the right side top end oiling."

Is this true for Dnepr's too? Was I supposed to drill holes through the front bearing on the crankshaft?

This is important, because I certainly didn't do this.

Re: Oil not getting to right cylinder head

Will letting it idle in place achieve the same thing? It's just that the bike's unregistered and the cop shop's just down the street. It's a $1400 fine if I get caught--$700 for an unregistered vehicle on the road, and $700 for driving a vehicle without insurance (and since you can't insure an unreg...

Re: Oil not getting to right cylinder head

Well, my oil light's going off like it should, so there must be something. It did occur to me some time later I should have hooked up my oil pressure gauge. But yeah, there' these little cylinder-shaped cam slider things that push the pushrods. They've got cutouts that must catch the mist, which the...

Re: Oil not getting to right cylinder head

Had another thought--maybe I'm just being too impatient? How long does it take a noticeable amount of oil to travel from the sump to the cylinder heads, considering it's got to become mist and go through those little sliders?

Re: Oil not getting to right cylinder head

OK, it's been a farking $#!+ of a year, but I cleaned out the engine with kero, made sure the channels were clear, and finally put it all back together again. It started. Yay. But there's no oil getting into either cylinder head. Before I snapped the crank, back when everything was running well, I w...

Re: Oil not getting to right cylinder head

OK, everyone's agreed that using the grease was a "bad choice", and may be the cause of my problem. I need to pull the engine back apart, as soon as I can make garage space again and clean it all out. Bugger. What's a good grease-remover for a "poverty-rider" to use inside the engine? I've been usin...

Re: Oil not getting to right cylinder head

Just so people are clear, my bike is a dnepr MT9, NOT a ural. I mention this because that tappet and tappet guide above does not look at all familiar. I didn't address how the oil gets into the crankshaft, which I assume is via magic, but the two journals each have a hole in them. I assume this is t...

Re: Oil not getting to right cylinder head

Do you mean the hole down the bottom? Doesn't that just allow oil out?

Re: Oil not getting to right cylinder head

I'd just make sure all orifices are clear.....if oid comes in via the valve pushers it has to go out some way and that's worth checking it's clear and a bit of sealer or gasket hasn't blocked it. Thought of that after posting, and pulled the cylinder out enough to pull out the sliders. The silders ...

Oil not getting to right cylinder head

OK, I've finally rebuilt my bike after snapping the crankshaft, and I'm feeling quite pleased with myself because it's starting with one kick and idling quite happily (if a bit fast. Adjusting the carbs is on the agenda). I'm particularly pleased with myself because I took the opportunity to complet...

Re: Snapped crank shaft

The guy who sold me the crankshaft was surprised by the undersizing, and the best theory he can come up with was that the Loyal Soviet Comrade Worker! had hit the vodka a bit hard that day. I find this theory eminently believable. Comrade probably had quotas to fill. His solution is to send me (free...

Re: Snapped crank shaft

OK, so I've gotten my new crank shaft, installed it in, and then noticed while playing with it a HUGE amount of slop between the big ends and crank pins. So pulled it all out again (swearing), and measured things up (wouldn't it have been wonderful to have done that BEFORE putting it in in the first...

Re: Snapped crank shaft

OK, so I've removed the engine. It turns out that the engine is light enough for one moderately fit and strong adult to carry any reasonable distance (with oil drained and gearbox already removed. No promises otherwise). My method, for those wanting to know, was to support the weight of the engine w...
