- In this second video in the series ,having removed the gas tanks and carbs we continue by removing the manifold that connected the carb to the heads. I notice the oxidization on the rubber rings that makes me winder if there was a vacuum leak here, its worth noting.
This is a good time to get the throttle cable and spark plug cables out of the way, followed by the exhaust pipes. Note, my rear pipe has a different bolt. We get a first look at the oil coming through the oil coming through the valve guide with the pipe removed, as well as some other oil leaks to address on the transmission.
This is followed by the removal of the pushrods and their tubes together using a standard technique for each one as described in the video. Note the 7/16 size tools and the ease of this operation with a kick start. Also, the spark plugs need to be removed to do this. Further note the half profile spanner being user for this, very important! Its also important to note that all parts be kept as a set as removed and the O rings generally get stick in and remain in the engine and lifters..
With this out of the way the central oil line is loosened from both sides. If you chamfered one side like i did you can push it in and turn to remove it without loosening the heads as shown, if not you will have to wait until the hards are loose.
Then the mounts on the other side are loosened and removed, its the large beam across the top of the engine. I reassemble all parts and nuts and washers so i don't loose them.
Finally, the heads are loosened in a star configuration with a 9/16 spanner, taking a little tension off with each interval. Eventually they can be turned by hand and removed, except for one that stays in!!!, note the location of this special one in each head.
Also, the read head requires a special tool for one bolt because of the reach, I use a distributor wrench to reach it for loosening. Also the shift linkage had to be removed for this along with the coil.. Funny, i noticed my seat bracket also got in the way of the rear seat removal. The rear cylinder also gets removed along with the oil line.
As each head is removed, an inspection is done, the bore looks fine, some buildup on the piston head, no head gasket leaks, but no worries.
With the heads out, were off to the machine shop!

This video has been incredibly helpful for me. It is an outstanding, professional presentation with no waffling or fn music. Sincere Thanks! from Australia. 11/10
Glad to hear it.
One of the best instructional videos I've ever seen on TH-cam - thank you, and I look forward to seeing the rest of this series!
Glad you found it helpful
Great video, keep up the good work. I have a 75 fxe that I do all the work on so I can really relate to these videos. Just the way you put them together and the commentary is fantastic, Thank you
Thanks, I appreciate it.
Man I tell ya I haven't done this in awhile on my shovel 71 but you did a great video
Thank you.
You are an excellent teacher. Well done.
Thank you! 😃
Thank you! These videos are excellent. I have an 81 FXWG...borescope shows the combustion chambers and piston tops are covered with carbon...not sure what to make of it yet. It doesn't blow smoke and compression is Fr 140 Rear 150. We'll see - and I'll keep watching I learn something every time. Thanks again!
It could just be rich with a little blow by, hard to say, good luck!
I am loving these videos! Great detail.
Glad you like em!
Problem not an issue. Issues are magazines and newspapers
?
you always put the bolts back in like me
Is it possible to remove the front rocker cover without pulling the whole head. I have a front exhaust push rod seal seeping and the front rocker box gasket. Engine only has 300 miles on it so I don't want to pull it all apart
Its not a rocker cover though. Its the entire rocker assembly. Yes it is possible to remove that only if frame clearance allows it. The push rods will need to be removed of course.
Hey do you got a video on 79 shovel other than TH-cam I'll pay for
I have no idea what this means/
