Ever wonder how an air-cooled VW engine is alighbored? Wonder no more, John Edwards @ Costa Mesa R&D Automotive Machine Shop explain's how it's done. (949) 631-6376 Don't forget to 'Click' and SUBSCRIBE.
Pretty cool, you guys in California? Alinebore tool is awesome. There is a guy up north of Seattle who has a shop with one and many other tools like this for all kinds of motors.
Thank you so much for making a video on this. I have never seen this process done. You guys make it look so easy. Do you do 36 and 40 horse engines as well?
What is ur bearing crush when doing a line bore ?? Example - O.D. bearing measures - 2.600 Do you set the cutters to cut the same or undersize & how much ??
Do you have a video of the shovel pins to prevent the case halves from shifting begin installed? I am interested in seeing that. BTW, is that a 3/8 flex head split beam torque wrench from Precision Instruments at about 4:16 to 4:36?
can you use two different engines to supply two "good" engine halves? I seem to recall some assemblies are tooled semi-assembled to make a better fit making it difficult to 'mix and match'
I wonder when the term transmogrified to "Alignboring"? We only ever referred to it as Line Boring back in the 60s-70's, which is a common machine shop term.
Question... how are you able to insert the tool all the way through the case with the cutters on it? Seems like the cutters would hang up on the journals if they're not yet cut. Thanks!
This was my question as well. Except for the blade, the OD of the cutter has plenty of clearance. The rod is slid through the case off-center allowing the blade to clear the case until the rod is recentered.
Jake. The correct way is to just clean up the rear bearing thrust surface. The choose the correct oversize rear main bearing and cut the rear inner thrust surface until the bearing is snug in the case. You can cut the case with this style bar, but not the bearing. I use a mini lathe.
You seriously cut right to size? Or do you cut it close and then hone to size? I'm a machinist and I would never try and hit a 0.0005" tolerance in a single shot like that. The smallest bit of run-out on that bar would cause the center journals to be oversize.
VW factory said VW case is not a rebuildable piece and if you think slideing 2 pilots in seal hole and oil sling opening got you a true center line you have no business working on any thing. Ever read book. Gene berg put out if not try to get you a copy
Voice of INexperience, Art. Twenty million VWs with this engine, probably fifteen million rebuilt with cases line bored (or align bored just like this) Success rate excellent. I probably did two thousand of them in1970s thru 90s. PortaTool in Clovis Calif originally manufactured this. They based it on a tool they did first for a similar job on Caterpillar hydraulic joints. Kent Moore bought PortaTool in about the late 80s. Tool is still being used very successfully by thousands of shops all over the planet. I was thrilled to buy one at an auction a month ago. Checked the cutters and just did one case to .020” & one to .040”. Checked with dial bore gauge, four bores in each case within a couple ten thousandths. There are some options to the PortaTool way of cutting the thrust, but looks like R&D has theirs dialed in about as good as it gets without a mill. True, they only set up on the two end holes & may not be perfectly indexed to cylinder decks, but darn close. Great even for high performance engines if you check all the rest of your work. I like the R&D practice of cutting thrust only the amount needed then turning #1 bearings flange to match; leaves more options for machining as necessary later. Engines. Done RIGHT by EXPERIENCED people that know what they are doing & WHY they do it, can last a LONG time & be rebuilt AGAIN SEVERAL TIMES.
@@Quentin60isthenew40Agreed, I built about 3000 VW engines from 85 to 2004 and I align bored every one of them with a PortaTool align boring bar. Works perfect. Anyone reading this interested in my equipment - it is for sale. Two complete set ups and about 50 sets of main bearings - every combination possible.

Love you John you are well missed. There will never be another you.
We use the same align bore bar at our VW shop ! We’ve had it for over 30 years and it works great !
Awesome job
very cool john
as always love your work
cheers from australia
Pretty cool, you guys in California? Alinebore tool is awesome. There is a guy up north of Seattle who has a shop with one and many other tools like this for all kinds of motors.
I allways bolt and torque barrels and heads on before align boring a block to allow for any distortion.
I like the alignment jig. I have not seen one like that.
We have a boring bar at our shop that is the exact same as yours !
The PortaTool is the worse linebore tool for the VW. The best one I found is the TruLine boring bar.
Thank you so much for making a video on this. I have never seen this process done. You guys make it look so easy. Do you do 36 and 40 horse engines as well?
This bar is specific to VW's, but with adapters, etc... you could possibly use it, but it's not that long.
What is ur bearing crush when doing a line bore ??
Example -
O.D. bearing measures - 2.600
Do you set the cutters to cut the same or undersize & how much ??
Is that cutter measurer something one could purchase?

Good 👍👍

the line boring is for the camshaft?
Awesome

Hi Dub Customs, obviously, the bearing outer dimensions are different.
This was my question as well. Except for the blade, the OD of the cutter has plenty of clearance. The rod is slid through the case off-center allowing the blade to clear the case until the rod is recentered.
Can that tool be used to do Iron?
What do mean you cut the thrust bearing to fit? Is there some sort of oversized one that can be machined down?
Thanks and great video by the way!
Jake.

You can cut the case with this style bar, but not the bearing.

hi its fantastic. whats the name of this tool? i was thinking do it myself. what i a can buy it, its better. can u tell me the name plz? thank u
Shuffle Pins is the correct term, or more precisely Anti-shuffle Pins.
What does that cost to be done
im afraid of the result why dont you show us how you install the gearing s on this case?
in Australia it's about $100

no! cases are machined in pairs!!
crankshaft mate
Was almost first.
