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.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.
I would rather machine the sprocket. Why create headaches for yourself in the future?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.
Measure the dowel pins with a micrometer. Mscsupply sells the correct size pins. Toyota won't sell them separately.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.
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 would rather machine the sprocket. Why create headaches for yourself in the future?
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.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.
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.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?
