That is a very easy thing for a machine shop to remedy for you. They could make some new dowels oversized on one end and stepped down on the other.

You would think? But nope, the "good" machine shop said they can't. I would have to source them myself. Then he started with his concerns pulling them out. So while I'm emailing catcams about the remedy, I ordered the cal-van dowel puller kit. I thought about just clamping the pin on a vise and use a brass bar to knock the cam off the pin. I've seen this done with v8 comp cams.

I would be very interested in knowing what Catcams says. I have a set of their hot street cams for the 2GR waiting for the rest of Marc’s swap parts to be finished.

I could have sworn I came across something about this in the past where the size of that pin changed at a certain mode year but I apparently didn’t save a link.

Freeze the cam and see how much the dowel shrinks, my guess is maybe only .0002” depending how cold you can get it. Basically makes this an interference fit but it should be ok. You can freeze it and assemble the the sprocket onto it.

I would rather machine the sprocket. Why create headaches for yourself in the future?

Measure the dowel pins with a micrometer. Mscsupply sells the correct size pins. Toyota won't sell them separately.

Catcams said pull them and put the correct sized dowel. Im buying them in multiple sizes. Undersized to oversized. 4.97mm to 5.06. Also pulling the old pins from the oem cams. I'm buying a cal-van dowel pin puller since this machine shop doesn't seem to want to do the work. Im really getting tired of these I know more than you shops. If I pay you to do a job, stfu and do the job Im paying you for. Sorry about the rant.

no need to do this. I'm calling misumi tomorrow for a stepped dowel pin. 5mm to 4mm with variances in diameter. I'm going this route or mscsupply. The only issue I forsee is not being able to take the current pins off myself with the puller.

I ordered Misumi stepped dowel pins MSFW5-15. They were the cheapest, fastest pins I could find. They're cheap but folks, lets learn a lesson from me. Don't rush, drop the dowel pin in the camgear. If it doesn't fall through then get a smaller one. I'm going to talk to another machine shop across town to see if they can do the work for me just in case this fix doesn't work.

Well amazon sent me a used tool. Glad I'm never going back to that machine shop. I got the dowel out in less than 2 minutes. This was the test run with the oem cams.

Need to exchange the step dowels. They have pretty deep grooves. In the meantime I took the plugs off the torn up sienna harness and jdm 2zz harness. I liked the cleaning chaser so much I got more.

decided to do my own fab work so I bought a welder. Getting 6/3 romex wired up in the morning. Welder is a Primeweld 225x tig welder. the local gas company only had 40cu argon tanks. Bought the welding table and dolly from northern tool with their coupons. Super cheap stuff during black friday, I'm glad I lucked out with everything. I have high hopes for a full titanium exhaust.

My job had a bunch of conduit pvc laying around so I took what I thought was more than enough but I was wrong. The techs didn't think I could fit the 3/4 pvc in my grocery getter. I thought 25-30 ft of romex would do it so I got 50ft, I used 48ft in total. First time doing this electrical work. I still need to clamp down the pvc and glue the joints outside. Home depot looked at me crazy for doing all this. If you're an electrician, feel free to nitpick my work.

Ready for the nit pick:
edit: looks like you put a carflex connector on pvc???

1. We don’t run PVC inside a house or in an attic.
2. We don’t run Romex in PVC. (It has a jacket)
3. Romex is more expensive that Tray Cable and both can be run exposed inside but tray can be run outside also.
4. The rounded Romex is always a X/3wg so that’s probably a 6/3wg. 6/2wg is flat. #8 and bigger are black. 14 is white, 12 is yellow, 10 is orange.
5. You did fine. Everything is safe. Make sure your terminations are clean and tight.

are you talking about the piece that connects to the box? LoL um yes, I used a vice to press the pvc in. I only paid for the romex and like $10 of joints.

I broke 3 flat head screwdrivers tightening things down. The 10/3 was just thrown around and held together with drywall screws, crazy looking shit. I have a phobia of electricity so I think I over did it. I can't believe how deceiving 6/3 is in pics. it looks like it bends and flex like a power cord but boy was i wrong.

I got my tig set up. Keep in mind I have zero experience with any of this stuff. First set up and start up was blowing everything up, couldnt get an arc started.

Then I checked the torch and realized the collet was put on backwards. Then I got a good arc but dirty tungsten.

I cleaned everything up and sharpened the tungsten to test things out again.

then I proceeded to empty out a 40cu ft tank practicing and realized I need a lot more argon so I ordered 125cu ft tank. I got 2 hours in and this was the end result

Did you get your phasers to fit on the front of your camshafts?

I got my 2GR tore down and verified my phasers do not fit my cams as well. When I contacted Cat Cams they wanted me to first verify the dowel pin had been drilled at the correct offset. I was wondering if you found only the incorrect dowel pin size or this as well?

i purchased stepped down dowel pins and they fit using those. i'm going clay the pistons to check the clearances. the only problem was waiting for the step down dowels to come in. i have an extra set of 4 if you need to buy a set asap.
