Building a Solid Twin Cam 103 Part 2

[@alanwhiteside410]

Great video’s part 1 & 2. You did a great & relaxing job of explaining everything and I really enjoyed the background music on the 2nd video. 🍻😎👍

[@empcycleworks]

Thank you

Awesome video brother and perfect timing I've just blown a piston and I'm getting a 110 sidewinder kit. You explain what your doing so well. Thanks brother All the best from NZ 🇳🇿

[@empcycleworks]

Thanks you. I’m glad I could help

[@MrDoyle07]

That was really well done! It gave me a load of great ideas. Thank you!

Thank you for watching

[@andreasugara]

Love your work man, clean and neat. 🔥

Thank you

[@9izm]

Educational experience for me with your knowledge of the twin cam motor. Thank you.

[@coreycallahan7443]

This was a great video for me to watch as a refresher course. Used to build a lot of engines when I was a young man . Shovelheads, small block Chevys, Pontiac 389 cid Tri-powers and so on. It’s been awhile though and now I am confident that I can rebuild the TC 103s on my my two Harleys when the time comes. Going to have to replace some of the tools that I used to have several moves ago but it will be worth the cost. Thank you for posting this. You have a new subscriber here. Keep up the good work.

[@idaholewis265]

I really Enjoyed these videos 👍 Thank you for your time making them

[@empcycleworks]

Thanks you

[@bigblue3568]

Can't you use the timing marks on the cam sprockets to determine top dead center? Marks closest to each other would be TDC for rear and marks both at top of each sprocket would be TDC for front ?

[@empcycleworks]

You probably can use it for an estimated tdc. I’m not sure the orientation and which cylinder the marks line up with. I don’t think front and rear would be 180 from the front on the cam marks. As far as tdc goes front and rear are not at the same point of crank rotation due to the single crank pin. (The pistons are not at the top of the cylinder at the same time) When I need top dead center, for cam timing, I use a degree wheel and positive stop.

[@robertbronson9432]

That was pretty cool to watch

[@empcycleworks]

Thanks

[@starmih]

Very good, but why didn’t you install hydraulic tensioners with an oil plate?

[@empcycleworks]

It’s not always in the budget

Great video thanks I enjoy this process.

Glad you enjoyed it!

[@rp75heavy]

I hit the head bolts with a brass drift and hammer 3times, and re TQ check again..!

[@empcycleworks]

Do the bolts loosen up when you strike them? I haven't heard of this before.

[@ed1494]

Can you do a 103 cam swap with wood TW 222 start to finish?

[@empcycleworks]

If that combo comes up, for sure

[@HammerHeadGarage]

Awesome. You need a light right where you are working.

[@empcycleworks]

Thank you. I’m working I. It

You do a great job, no bullshi* talk, just all facts !! THANKS

[@empcycleworks]

I appreciate that!

[@mgc5943]

The intake manifold went in at 11:45 but then it was off at 12:21. ??

[@empcycleworks]

Editing mistake, sorry

[@mgc5943]

I saw that later in the video.. I jumped the gun

[@ed1494]

Thank you. Excellent!!!! Thats how its done.

[@empcycleworks]

You're welcome!

[@roobie_black]

What cams did you go with from Woods? I have the same 103, and recently did Woods 777+ S&S 106 Big Bore kit + 2-1 FC exhaust, + s&s intake + FP3 tuner. I think i want to change out the tuner for better tuning. Now i have to clutch is slipping, so gonna add new clutch so it stops slipping during acceleration.

[@empcycleworks]

It was there 999 I believe

[@roobie_black]

@EMP Cycle Works I'm curious to know and see the difference between the 777 vs 999. Do you plan on Dino it?

[@CharlieMetcalf]

Really enjoy watching your motor builds. Curious, why does Harley use such high inch lbs instead of low ft lbs. 110 - 9 120 - 10 Curious.

[@empcycleworks]

Thanks for the comment! I think the service manual uses inch pounds for anything 10 ft pounds and under.

[@chiller5438]

Love the videos…looking at upgrading my 07 fatboy 96ci to a 107 and heads. Ive had cams, oil pump and cam plate already and was told I had 11 thou run out on crank. Would you do the build without doing the crank or just be happy with what I have?

[@empcycleworks]

11 thou is to much run out for my liking. What cam plate and oil pump do you have installed? Most of the after market setups want a maximum of 0.005" run out on the pinion. Before you build a 107 I would get that crank serviced. Thanks for the comment!

[@chiller5438]

@@empcycleworks thanks for your response, it’s a fueling plate and pump with S&S cams.

[@bullast2046]

S&S crank, dark horse/ machine work, decent build.. why not gear drive cam chest?

[@empcycleworks]

Maxed out the budget

[@samslade739]

Great video. Thanks. How do you feel about a Timken crank bearing upgrade? Some builders insist that it is needed. However, I see allot of high horse engines out there on the road with stock style bearings.

[@empcycleworks]

I think it’s a good upgrade if your crank needs service. Certainly not 100% necessary.

[@travj4450]

Thank you for sharing knowledge!

[@empcycleworks]

Thank you for watching

[@derrickw5660]

Any reason why you’re using the stock cam plate...

[@empcycleworks]

The budget! The late model TwinCam camplates are a pretty good unit. I used the Feuling HP Plus oil pump, lifters and pressure relief valve on this motor and it has 40 psi oil pressure at idle. If the budget would of allowed, upgrading to the fueling race series or S&S camplate/oil pump are my go to. Thanks for the comment

[@paultrainer1049]

Nice job

[@empcycleworks]

Thank you!

[@tonybedingfield9085]

Well done

[@empcycleworks]

Thank you

[@theone9564]

Was there a part 3

[@empcycleworks]

Unfortunately no. I only recorded the motor assembly

[@leom761]

What was the torque spec for the bolts that hold the engine to the transmission? I haven’t been able to find it anywhere and I’m not sure if there’s an actual Torque spec

[@alanwhiteside410]

There is a torque for every bolt made. You can find torque charts on Google Images I screenshot things like that and file them in a special file on my cell phone I titled “Charts” for future reference.

[@jbpooh]

I've heard I needed to check piston deck height without the rings before install. Is that something you do? I didn't go crazy with the build, just going for 103 to 107 with a 590 cam. Is there any other checks I need to do or should it be fine in your opinion?

[@empcycleworks]

Yes that is a good thing to check. In most instances you can get by with a straight edge and a feeler gauge to measure it. Every part has different tolerances. I do check that.

[@jbpooh]

@@empcycleworks ok. Is it still required to check valve clearance with putty?

[@RobRocker09]

love your video's bro. I subscribed

[@empcycleworks]

Thank you

[@JoeNolasco]

Great videos! Just curious how much power this setup makes?

[@empcycleworks]

115/115

[@joeabbott7839]

I have evo1340an bottom cases got damaged an what you when you replace the case it will not macthnumber do carry the Old case with you

[@empcycleworks]

I dont stock any cases, unfortunately. If you get a case from Harley, I think they usually come without a number. So you can stamp your own. Not sure if new evo cases are available though.

[@cornbred1]

Nice work👍🏿💯

[@empcycleworks]

Thank you

[@lanea4642]

I noticed you weren't concerned about any PTV?

[@empcycleworks]

This set up had over 0.100" of PTV clearance. Unfortunately, I did not record that process. With this cam, Valve to Valve is way more of a concern.

[@CaffeineThrottle]

Sounds like a nice setup but if that's a monster what's my 117" ? 😳

[@empcycleworks]

A 14" Bigger Monster? lol. The thumbnail is just for attention. I had Twin Cam instead of monster originally. Just trying different things. thanks for the comment

[@jeremyolguin7116]

How much HP did that put out?

[@empcycleworks]

Something like 115. I dont remember exactly

[@jeremyolguin7116]

Really! That's pretty good numbers for thsg little of work

[@rexmilanista]

Thats awesome work man! its nice quality workmanship like this! Question about the heads you used, They say "screamin eagle" on them, are they off of a 110?

[@empcycleworks]

These heads are straight out of the Screamin Eagle catalog at the time this motor was originally assembled. They would have came in the 103 Performance crate engine, before they came out with the 110. Im not sure about what the difference is between these heads and one that come with he 110.

[@rexmilanista]

@@empcycleworks Right on buds! thanks for the info! Like i said before its great seeing awesome workmanship along with a thorough explanation of how everything is going together and why! Keep up the killer work!

[@michaelspicer1236]

How did this fish up? Is there a part three? Should a costomer ask for a compression test or a leak down? I think you were very thoughal. .

[@arthurfiltzanidis7045]
