Predator 420cc Stage 2 Build Pt. 1 | Cam, Rod, Flywheel, & Etc!

[@ZippoVarga]

Here's a little tip for removing bearings and bushings in a blind hole guys. Pack the center hole with grease then use a punch or wood dowel the size of the hole in the bearing and hammer the grease into the hole. It will hydraulically force the bearing out of its seat and it's quick and easy to do. Thanks for taking us along! Zip~

That's a great tip that actually works!

Honestly I don’t speak for everyone that watches your channel but Ike and John for a 30 min video is good by me. You guys mesh very well. Keep up the good work! Nice build also!

[@ZippoVarga]

As for installing/changing valve springs with the head on. Pack the void with the piston at about 1/2" from top dead center with clothes line rope or the like, then set the piston at TDC, this will hold the valves in place while you reinstall the valve springs. Then simply pull the rope out after you're finished. Where there's a will there's a way! Cheers Guys! Zip~ p.s. I know these tips are after the fact on this engine, but will come in REAL handy on future builds.

[@donaldpowers5557]

too old school!

[@markwise9868]

Thread a fitting for an air hose into the spark plug hole. Fill cylinder with compressed air.

[@MrTheHillfolk]

camjamsdad 2 screwdrivers on each side of the retainer and push down to compress the spring. There’s so much old school tech tips they coulda used for that, like someone else said it’s after the fact. They can try it next time Edit: 2 screwdrivers and some metal chunks (sockets) as fulcrums. Hopefully ya can see what I’m trying to convey but the darn words aren’t cooperating ! 🤣

[@pogonick55]

I don't think I would sacrifice electric start and charging coils for a billet flywheel. Especially in a golf cart application, you gonna have to lift the seat to start it every time

[@matthewjohnson2495]

pogosticknick They can use the golf cart starter generator and all they would have to do is put a pulley on before the clutch so the starter has a way to turn the motor

[@MrTheHillfolk]

I’m not familiar with the predators , is it a normal ring gear that’s pressed on? Heat it up a little and press it off if so. Then the next question is, would it fit on the new flywheeel?

[@joelboley2344]

@@MrTheHillfolk won't fit

[@robertjames7869]

I agree with pogo, losing the electricals will bring it's own inherent issues. As for retaining reverse, there are carts that came with the reverse/forward in the rear end. Ezgo, club car, I'm not sure. If they can find one of those, great. Another issue will be grenading the rear end with that power increase. They were designed for 12 to 15 mph

[@MrTheHillfolk]

Joel Boley Heh I figured as much. Sometimes I wish I had a 5 acre yard piled with junk so I can try stuff. Like see what ring gear might be close enough if you shave a few thou off the od off the flywheel,or something. I’ve got access to a lathe and mill and sometimes it’s fun to whittle your way out of (or into) a situation.

[@tonytaunton2628]

Cars and cameras!! Look! Great videos guys. Your channel has inspired me to build a golf cart about 3 months ago when my stock engine finally blew up. I started with a 500cc Polaris four wheeler engine I Hooked it up to stock rear end and as you could imagine I overheated the stock rear end and the old brakes were non existent and as you can imagine going 30mph+ with no brakes was not fun! So I decided to scratch the idea and go with the duromax 16hp 420cc electric start and the 30 series converter only for short period until I get a better converter . The hardest thing I’ve done to it is the live axle swap. Installing the axle was easy but making it stop is a lot harder than one might think I’ve tried the mechanical brake caliper kit from go power sports but it doesn’t stop like I want it to I am currently waiting on the hydraulic caliper kit to see if that helps to stop it a lil better and I am running 25” tires and a top speed of 49mph so that could be a reason it doesn’t stop I am curious to see how yall are going to build your golf cart, how fast it’s going to be and how fast is it going to stop!! Most important be careful and always remember ITLL BE FINE!!

[@owenbame1131]

Nothing like using an angle grinder in an engine block Itll be fine

[@dadsvespa]

Guys, great video. Here's a mechanics secret on how to change valve springs, without removing the heads. An old mechanic showed me how to change the valve seals and springs on a V8 without removing the heads. I said Huh !?? WhotheWhatthe !.... Then he showed how he used an old spark plug, removed the ceramic element, brazed the male part of an air hose quick connect to the spark plug..screwed it into the head, and applied air pressure. And faster than you can say hiyahiya !..he used a forked tool he made to pry down on the valves. It pivoted on the rocker arm stud. Worked perfectly !! I have use one I made, on many engines since he showed me in ...(1982)...Ahhemm !! (getting old guys !) lol. Anywho !...just a thought. Peace !

[@GearHeadWW23]

[@wtftolate3782]

Have your billet fly wheel machined and have the ring gear attached to it. So you can keep your starter. Also, you can have your charging coils added. Not hard to do.

[@Paulman50]

Yea not a big job, I was wandering why they didn't go down that way.

[@robertjames7869]

Overwhelm? Really? I'm down for the longer, the better! Great project, as I have an older golf cart and I'm interested in how you plan on keeping/have reverse. Most gas carts have a starter /generator and the engine is designed to run backwards to accommodate this. Whatever you come up with, if it works, I'm installing it

[@Alfred..E..Neuman]

Overwhelm!, Really!..That's what I say!...They must think they're talking to a bunch of young children that would overwhelm them!...The video was just starting to get interesting and I'm definitely down for half hour vids, the longer the better as their vids are way too short to begin with!

[@robertjames7869]

RK, I was saying that in jest. I'm pretty sure that John was referring to possibly the video becoming tedious, not that the content was overwhelming us or over the viewer's head. In all seriousness, this is a great channel and the number of subscribers in the few short years of existence is testament to that. I truly look forward to every Monday and Wednesday.

[@thepittsstop4540]

Tip for removing valve springs. With the Piston about 1/4 way down the bore, insert a length of clean nylon rope into the spark plug hole. Be sure to tie a knot so it doesn't disappear 😉. Bring piston up until it compresses the rope, holding valves in place. R/ R valve springs, take piston back down and remove rope.

[@allenmckinney9533]

Run an air hose to the spark plug hole. That will allow the air pressure to hold the valves in place. My Harbor freight compression tester has 3 hoses that can be used for this method.

[@rogermarshall8991]

Put a dowl or your finger in the port. Hold the valve up

[@AdversityZone]

with the valve springs you get an old spark plug and remove the guts of it and weld a air fitting to it then just put it in and add an air line and the pressure will hold the valves in place

[@ardennielsen3761]

15:45 the tool you are needing consists on a C-clamp and a short section of pipe with a cut away on one side. already have C-clamp and some small pipe can make that tool for less then $1.

[@ghomerhust]

[@ChrisEdwardsRestoration]

5:15 you don't need a bearing / slide hammer for that removal, use the old grease trick. get a bolt that fits as close as possible to the diameter of the hole, fill it with bearing grease, wrap the bolt in tape so its nice and snug, insert bolt over greased hole, tap with hammer, bearing pops right out, I've used this on pilot bearings for years. my dad used to use BREAD, yes bread bread. but thats just not right

you can try putting the piston at TDC and shoving rope into the spark plug hole to fill up the combustion chamber to prevent the valves from dropping in while the springs are off.

[@MotorcycleJunky07]

Great video guys! Loved the specifics! Part numbers, torque specs, process order, etc. You guys should invest into a TIG welder. No sparks with a TIG welder!

[@kdsoverland]

if you want to work on valves with the head still on, take an spark plug drill it out and weld an air fitting on it. screw it in and connect it to compressed air. that wai the valves will stay close and you will be able to work on it... love the vids greeting from Namibia.

Pro tip for the governor retainer cut the wheel so you have a flat direct spot and then use an old chizzle and put it under the clip right on one side near the gap and if u have to tap it under the clip and then just pry up on the clip do that a few times and itll be bent enough to get it off works for me every time in 5 minutes or less

Use the hose from a compression gauge, apply air pressure from a compressor and it will hold the valves in place while you have the springs off.

So you're not going to be able to run a starterator on it I'm guessing since no charging system and also if no charging system also no lights so will that still be road legal there. I know here in SC you can run them on the roads in certain areas but they have to have headlights, tail lights and a rearview mirror.

You could but it wouldn't be a charging system to recharge the battery so every 3-5 starts im guessing the battery would need to be removed and charged.

A few points, you may be able to swap the ring gear by heating it up to remove it, that gasket will likely set the end play so the engine will be very tight to turn if you just use silicone, eBay/amazon has a $16 valve spring compressor that works fantastic on small valved heads.

[@ClutchFirstPhilippines]

I’d rather watch for 30 minutes the these lil 16 minutes video but keep up the good work guys

[@btpearce]

Have you ever seen the rope trick when working on valves in a head that is still on the engine? You take the plug out and thread a long rope into the cylinder leaving the end of the rope sticking out so you can retrieve it after you are finished working on the valves. you rotate the crank to press the rope up against the valves to hold them so they don't fall into the cylinder. You will also need a spring compressor that goes on the rocker assembly so you can compress the spring and remove the keepers and the spring. After you are done back the pressure off the rope and pull the rope back out. ( Not sure if that will work on this type engine have seen it done on a car engine before.)

[@hammerT2997]

Awesome as always. I'm good with a thirty minute video lol

An easy way to get bearings out with welding in your engine, is get a bar of soap, wedge it into the bearing, then get a socket or a dowel or something and hammer in on the soap. It will expand and push the bearing out... I've seen Mike Finnegan do it a bunch of times on Finnegan's Garage. Man that thing must have super low compression... flat piston and hemi head means huge gap. Remember when domed pistons were a thing? I know Ike does because he used to have a bastardized Triumph chopper and Triumphs are hemis with domed pistons.

Hey y'all. When I did the valve springs on my Holden V8 last year, I used a cheap eBay special overhead valve compressor and a cylinder leak down tester to keep the valves seated, no head removal again. I had to add the inner spring of the dual set after the cam was run in. Fun job when there is 300lb spring pressure there!

[@dangfangled7045]

Take an old spark plug break the porcelain off then drill out center with 3\16 drill. Then weld on an air hose connector. Install It in spark plug hole and connect your air supply hose and it will hold your valves in place. Old school from Canada .

if you have a compression guage screw the cylinder end in the spark plug hole and plug the tool end into a compressor hose.you will have to have the side plate on the motor because the compressed air will push the piston to bottom dead center. ive done it many times putting new valve seals in cars and trucks.

An easy way to get those bearings out that y'all had to weld two is Take some grease pack in there then take a socket are a piece of solid shaft that'll go inside the bearing and pop it in the grease pressure will push the bearing out like removing I pilot bearing in a car engine then you wouldn't have to worry about the weld getting in your cylinder wall are on your crankshaft
