Aircooled.net. I am building a 2110. 82x90.5.
Didn't feel like doing that part myself and it was one less thing to have to do.


Gotcha, missed the mention of a stroker crank. I got the last cam I bought clearance also, saves a lot of work and messing around.

Continued the teardown of the old motor. I still can't believe this thing ran as long as it did. Check this out...

Push rods. Normal ones from 3/4 side. Scuffed up ones 1/2 side. No marks in the push rod tubes. Have no idea how they got marked up like that unless it was prior to the rebuild of this motor...

I always assumed the thrust bearing was pounded out on this case, but apparently I was wrong. Thrust bearing seems fine and in place solid. However, I believe this bearing was the problem. I don't think it's supposed to be loose!! Shocked Shocked

I have 2 questions...

1) I got these Scat I-beam connecting rods and on the outside of the box they have the weights written down. Is it safe to assume these have already been balanced and matched?

2) How do you guys clean your new cases? Air? Water jet? Solvent? There is a pile of black sand looking stuff in the corner and I'm not sure what would be inside some of the passages.

Worked on the engine a bit today. Got the cam gear on the cam (W120). Installed the cam bearings and set cam thrust .002". Smile

Did the lifter mod...

Ran into my first problem though. On the 1/2 side of the case, the cam lobe to lifter clearance measured .047" which I believe is okay, however the 3/4 side of the case I only have .027" clearance. Not sure what to do here and what would be easiest. Going to post in the engine forum to get help.

Whew been busy the last week or so. Wink Lost my build partner for a week as she left yesterday for sunny California to compete in the IBJJF Worlds Competition. Her first time going so pretty excited for her. Anxious

Anyway, this is what has been going on...

Used this nice hot plate/stirrer to heat up the gear to go on the crankshaft. Worked okay, but worked even better when I put the gear in a pot of hot oil.

Cleaning the pistons and cylinders...

Gaps of the compression rings. As noted below, top ring needed slight shaving/adjusting...

Deck height is going to be negative as the piston is sticking out of the cylinder (which I new from my combo of parts)...

So, just like the lifters (that were different in height on the 1/2 side compared to the 3/4 side) so are the deck heights. Not a lot but a difference none the less. Not 100% sure of the accuracy either as I was using a straight edge to judge when piston was level with cylinder top. And YES I am well aware that is not the proper way to use the deck height tool, but it makes a great base for the magnet! Laughing

First measurement of end play on the crank was with the flywheel and crank outside of the case, flywheel not torqued on and using feeler gauges. I got 0.050". This measurement is with the flywheel torqued on, crank in the case, case halves torqued on. 0.046"

Crankshaft spinning freely, no issues with clearance anywhere I can feel/see...

Not much done today. Broke down crankshaft, removed gears, bearing, pulley and flywheel. Heated gears back up and put back on. Put Loctite on the grub screws in the crank. Packed the crank, pulley, flywheel and pressure plate so I can deliver it to the machine shop tomorrow to have it all balanced. I ordered Rasser 050 heads from Mofoco along with new dual Weber IDF 40's.

Tapped the oil gallery from the oil pump to engine. I'll be going full flow and the oil pump I purchased doesn't have an outlet to plug.

Threw the distributor in to check its endplay. Was well over 0.100"! Shocked Then I noticed the distributor clamp wasn't sitting flush with the case and the distributor wasn't in all the way because of it. A little persuasion in the vice with channel locks and problem solved. Ended up with an endplay of 0.062". Very Happy

Been busy the last couple months and the heat has been unbearable to work in the garage. Sick Parts also took a while to clear customs. Brick wall I had stuff coming from Vancouver BC, California, Utah, Michigan and NY state. Smile

New Heads. Mofoco 050 Rasser...

Rocker geometry was a pain in the ASS!! Evil or Very Mad The only way I could get it bang on with the rockers I ordered was to remove the lash caps. I now have most of the parts installed along with new tin. I also purchased a sync-link system. I didn't want the added frustration and hassle with the bar setup. All I have left to do is install the external oil filter and hoses, some electrical tidy up, prime the oil system, install the push rods and rockers, put on the exhaust, then install the engine, connect new fuel pump and fuel lines and break it in. Hopefully by Friday evening or Saturday morning. Dancing

Looking good!
Did you ever find a functioning link to replace the hunterdunebuggy.com?

I'm about ready to start a complete rebuild of a Meyers Tow'd, including rebuilding what was supposed to be a "never had oil, built with all new parts" motor that flowed oil out as fast as you could pour it in.

We're not that far apart, should get together sometime to compare notes. 2 of our sons run a race shop at Calabogie Motorsports Park, oldest daughter is a paramedic with Renfrew County, so we are familiar with the area.

FB, Tourist here... When you mention marks - is that a good thing because the machine shop lightened the part at that/those spots? ...and the pulley was balanced? (tho' would not the pulley be pretty low mass?)

I envy your ability to focus and take your time.

You did reinstall the lash caps right? Those aren't optional unless you are running elephant foot adjuster screws. The ends of SS valves will mushroom, they aren't hard enough.

Nice engine build.

No I haven't found a link yet. I thought I screen grabbed it though, but I can't find it in the oodles of data on my computer. I wouldn't mind meeting you. If you are doing a rebuild, I could lend you some tools if you don't have any especially when it comes to the engine. The part of the cost I didn't anticipate was the umpteen number of vw tools required. Pretty sure I have all of them now! Razz

Hi
Yes those are the balance marks. The pulley is called an equalizer pulley. It weighs in around 5 3/4 lbs.

No I didn't reinstall the lash caps. There was no way I could get the geometry correct. I had 2 stacks of 8 shims under the rocker assembly and it still was way off. Removed the lash caps and it lined right up with 2 stacks of 2 shims. I think the lash cap thickness was the issue. I don't have elephant foot adjuster screws. I have the ball style swivel. I read some stories about the elephant foot style adjusters breaking so I steered clear of them.

Seeing as it is late in the year now, I will just get it broke in and running with the single springs. As long as I don't hammer on it I should be fine. I will put the lash caps on later with the double springs and probably change the rockers out for some SCAT's with the adjuster on the push rod end. Not sure what to do.

What's the issue with the valve stems mushrooming other than not being able to remove the valves? I figure with the low miles I do every year, I'll be long dead and buried before I would have to do a valve job. Laughing

Just curious here - what is the advantage of lightening the flywheel and putting on a heavy pulley?
