BBBC #12

This post is part of the blogger challenge titled BBBC. Today's topic is:

12. What event are you currently looking most forward to?

Oh, this is easy. I'm looking forward to all of these pieces to be back on the Ural and no longer on the workbench. The "event" will be the Ural leaving the garage under its own power. Thursday morning, Jed came by to give me a hand removing the engine and transmission. Starting with the battery cables we disconnected all of the wiring, removed the air cleaner, carbs, starter, alternator, rear wheel, final drive, shift levers, rear brake switch, clutch cable, crash bar and possibly a few more things.

We then managed to wiggle the engine from the frame. All of this was done without removing the sidecar like I had done last winter while replacing the bad lifter. We then started engine disassembly. The transmission came off easily with only one bolt and a couple of nuts.
The left head and cylinder came off easily though the use of very poor quality snap rings, the piston had a ridge built up preventing the wrist pins from easily sliding out. The right cylinder wouldn't easily break loose from the engine. I had to get a "dead blow" mallet which is a plastic hammer with a couple of pounds of steel BB's that move inside of the head. With a pry bar to provide some preload, it came free.

Here is the view of the clutch. Bruce from Ketchikan is bringing up some specialized Ural tools to remove the clutch and flywheel. I need to pick up some metric allen wrenches for the 3/8" ratchet to break some of these bolts free. I believe that thread lock was used on the clutch bolts and Raceway used some on the front timing cover. None of the bolts would budge. I'll get some Mapp gas to provide heat on the bolts to melt the thread lock compound.

So, not strictly an "event" but close enough in my book.

We are having some wonderful weather. Here I'm stopped at the Ballaine Lake turnout. I have to be careful of where I'm stopped as the Beemer has neither reverse or a parking brake. It seems to be running okay but it needs some maintenance. But pretty reliable for a 33 year old motorcycle. Now time for some Ibuprofen...

And here are a couple more PBC videos. Only three more days before the PBC is over.

Thanks for the pics RichardM, and yes, there's loctite on those screws holding down the clutch plates.

Hmmm, deadblow hammer, never heard of such a tool....I've got a rubber mallet but think that would be better to get....

Re your posting on SS, I don't believe you're supposed to have any lateral movement on that crankshaft arm. On my Valencia's control arm, I was able to pull it in/out slightly, also a sign of a failed bearing.

I've seen it done both ways, with sidecar removed and without removing the sidecar...if I had access to a motorcycle lift, I'd remove the sidecar, otherwise, do as you did and keep the sidecar mounted. A lift would be sweet though....someday, somehow.

Remember,the pushrod seals are marked to ensure you put them back on, oriented correctly.

The deadblow hammer doesn't bounce like the rubber mallet when you hit something. And the steel shot moving in head provides the real force.

No movement in/out at all on either rod. Hence no knock when the engine was running. I'll have a better idea once I pull the crank and the cam. A lift would be easier on your back but it's kind of a hassle to remove the sidecar.

Richard, I certainly believe that a functional motorcycle counts as an event to look forward to.

If nothing else, the URAL’s downtime does give the Beemer a chance to get out and about (Or is it "oot 'n' aboot"? Maybe that's just a Canadian thing. :) ). Do you ride the BMW much anymore otherwise?

RichardM said...

No, I don't ride the BMW much anymore. The steering is very heavy and the gearing isn't optimal for sidecar use. It's geared way too high. The Ural is just more pleasant to ride. I've been looking at getting rid of the Coy sidecar and reverting the BMW back to 2 wheels but this is the second time in a little over a year that the BMW had to come out during the winter as the "spare rig".

A product called Kroil Oil works on frozen nuts. They sell it at Amazon. www.amazon.com/Kano-Kroil...KROIL/.../B000F09C...

RichardM said...

Thank you for the recommendation. Most vendors refuse to ship a lot of liquids and solvents to Alaska. Many refuse to even ship motorcycle tires. They claim that "it's illegal"...

Home Depot sells it in the lower 48.

I'm with Ry. The Ural leaving the garage reassembled and under its own power classifies as an event in my book!
