Engine removal

Post #1 by Whiskerfish » Thu Jan 29, 2009 9:13 pm

Carbs and exhaust removed previously. Remove any Fairing supports and crash bars and horns now.

Image

Drain Coolant
Image

Image

Disconnect upper hose
Image

Disconnect lower rad housing and seperate from pump housing
Image

Disconnect wiring to Rad fan and overflow hose to expansion tank. Remove Rad Cap and remove radiator. Yes my fan is a bit different. Stock applications you look behind the rad next to the fan for the wiring connector.

Image


Drain Oil, Remove oil filter and Belt covers.

Image

Disconnect Tach Cable and Fuel line, I elected to disconnect the Clutch cable from the bike and take it out with the engine in this situation.

Image

Disconnect Fuel Filter from Fuel Tank and remove
Image

Disconnect Starter hot wire. Make sure to use wrench to hold stud from turning while removing outer nut.
Image
Image

Disconnect the electronic ignition or Point cable wiring.
Image

On a 78/79 you remove this connector to disconnect the engine harness. On a 75-77 you will have to disconnect the wires individually.
Image
Image

Disconnect or cut the three Yellow wires from the stator. (yes mine are red due to a modifcation I did)

Remove the forward upper bolts and the bolts to the frame for the heat shield. Carefully remove the Heat shield. Ensure to note where the rubber anti chaf gromets go between the heat shield and the frame
Image
It does require some wiggling but it will come out without being bent!!
Image

Remove the upper rear engine hangers. Take care not to loose the long bolt, OEM replacement is liike $26.00!!
Image

Disconnect and remove the rear Brake Switch, then remove Right and Left hand lower engine mount bolt.
Image

Slide the driveshaft rubber boot forward and rotate rear wheel until the snap ring is in view.
Image

Good 90 degree snap-ring pliers are almost a must for this job.
Image
Image

Now slide the boot back and push the drive shaft back along the spline. It will not have enought room to disconnect yet.
Image

Place your support. A Bike Jack works very nice. A floor style car jack also works well
Image

Do a thourough final inspection to make sure all wires and cables are clear and will not snag when you are at a critical point.

Take slight tension with the jack and remove the "removable frame section" from the left side of the bike. The cross bolt may require some adjustment of the jack. When the frame section is gone you need to wiggle the engine out of the mounts on the right hand side so it can move forward a hair to disconnect the driveshaft. If the fuel tank is installed the engine will not have clearance to go up high enough to get clear of the right hand mounts. you need to work it down and forward. It only takes like a 1/4 inch to seperate the drive shaft.


Image

Lower the engine slightly and slide out the left side.

That's very nice, WF. Great pics and well explained. Thank you.

Just a couple of questions ...

Did you do that removal for this writeup, or vice versa?

And, that shirt still fits you? I outgrew mine 20 years ago!

Great job Whisker! I would have added the technical language involved during the circlip removal, but this is a family oriented website...

Roady not sure exactly what the question means? I took the pics Wednesday late afternoon when I pulled the engine and did the write up last night.There are quite a few pics I did not use here http://www.ngwclub.com/gallery/v/wingmans/whiskerfish/Engine-Removal If you want to do "you're thing" to this please feel free. I do not have the patience to do what you do :lol:

If you look at the pics I did not use you will see that I had to do some things a bit differently on this removal. The Cross bolt under the engine was seized in the engine. I soaked and beat it for a while then I decided it was easier to just get out the sawzall and remove the opposite side frame.

It looks to me that the driveshaft snap ring is worn out. Or, is that just an optical illusion made by the flash?

One thing I do when pulling an engine is to inspect every single nut, bolt, bracket etc., to see what needs replacing and what just needs clean up.

Actually the snap ring was good. Must a optical Delusion ;) but that brings up a excellent point. For something that is that much of a PITA to change plan ahead and have a new one ready to go! They don't cost much at all and do deform very easily.

Yes under normal situations the very next step would be a thourough cleaning and inspection for damaged or worn components. This one in particular is getting parted out.

But a frozen bolt adds the "technical terms" back in. Image

Now that everything's out of the way, how about some nice close ups of that centerstand cross member? Maybe with some of a good one for comparison. Thats scary.

WF ... I just asked that because there'd been talk about us needing an engine removal tutorial and up pops yours. Great timing.

I wouldn't touch a thing in your writeup, it's excellent.

Whisker, is this the engine from your bagger? If so why are you parting it out?

Yes that is my Bagger. She has been sent off to the happy roads in the sky! I thought about repairing the centerstand support but as bad as that was corroded I was concerned about the rest of the lower frame. Well as it turns out the rest of the frame was solid. I did not find that out until I took the sawzall to it. The engine was tired and the primary chain was making too much noise no matter how tight she was tunned. She had somewhere between 160 and 170,000 miles and it was time to replace her. My Black bike will be my new touring bike wearing the Bagger's "clothing". I have wanted to build a 75 for the street so once this conversion is complete I will start on that. Once the parts I need come in I should have this wrapped up in just a day or 2. All the hard stuff is done.

No that bell was given to me by a special Lady friend to help keep the gremlins off me and my bike. It is something I will always Treasure. It will transfer over to the "new" dresser.
