 Posted: Fri Aug 08, 2025 12:00 pm Post subject: .06” end play |
 |
|
I saw a 1776 engine online. I was slightly interested but it said the end play was .06”. I asked if he meant.006”. He said no if you go that tight on a new bearing it will lock up.
I’d never heard that. Is that true? I’m eventually going to rebuild a 1600 dp for my 67 and am trying to learn all I can. Thanks in advance!

.003"-.005" is the factory spec.

Absolutely not!
And don't even consider buying anything from this guy either

Supposedly it only has 3,000 miles on it and was fairly cheap, which is why I was initially interested. I thought the end play thing was a typo til he confirmed it.
Definitely not interested anymore! Thanks for the replies. I'm sure I'll have a ton of questions whenever I go down the road to rebuild my engine, but in the meantime I'm stocking up on information.

I found this page which lists common crank endplay ranges for popular engines:
https://www.enginelabs.com/engine-tech/blueprint-s...t-endplay/
You can see from the above table the largest value is 0.012" = 12-thousandths of an inch (12/1000). That's seller is suggesting 0.060" = 60-thousandths of an inch (60/1000) is acceptable end play for a relatively new engine. That is 5x the largest value on the table! 
The VW spec for end play is on the low end but it is not the lowest. I found that the GM LS IV engine has a recommended crank end play of 0.0015"- 0.0078" On the tight end that is 15-ten-thousandths (15/10,000) of an inch!!!

You'll hear .06" as an audible THUNK CLUNK.
Think about how much stress that puts on the rods every time the clutch is actuated...

Plus how radical the timing would be. Everytime you accelerated or decelerated, the timing would change!
Man, the drivability complaint would be crazy odd sounding!
