Posted: Sun Sep 19, 2021 4:57 pm Post subject: Type 4 Bus Gland Nut |
|
|
I'm tired of searching with no hits. My 1.8l type 4 Bus needs the crank reshimmed and I'm trying to find a new glad nut. What size is it and where can I buy one? Assuming it's not the same nut used on type 1s.

The T4 doesn't use a gland nut. The flywheel attaches with 5 bolts. _________________ (o\_i_/o) I'm not a vegetarian because I love animals, I'm a vegetarian because I hate plants. |

That explains it! So is it okay to reuse the bolts or should they be replaced every time I pull the flywheel?

Reuse the bolts. 87 Ft*Lbs.
Make sure you use a new lock plate. In a pinch, the original one can be reused if it is flipped over, but they are generally a one and done deal. New ones are inexpensive. Good insurance.
While the flywheel is off, replace the pilot bearing. Also check to make sure the felt ring is in good shape as well. _________________ 1800 Type 4 Berrien 295

Be VERY careful trying to readjust endplay on a used engine. While not very common with a later Bus engine with an aluminum case, the magnesium cases of the Beetle engines gain endplay when the case wears, and the front flywheel bearing moves within the case. This makes the endplay some of the crank to bearing wear, but also the bearing movement within the case. Attempting to take up all the play by shimming the bearing will have the bearing seize on the crank, damaging the crank/case. When you remove your flywheel, check that the front bearing isn’t moving within the case. |

Woah, woah, woah......why are you "reshimming" it? The type 4 case is aluminum is rarely needs a thrust cut and changing shims wouldn't fix it anyway. Was the engine just rebuilt? Are you measuring too much end play all of a sudden?
The only time you should be changing the end play shims is during a rebuild, or if you are changing the flywheel. _________________ Please "LIKE" us on facebook to see what we are working on.

It's an older rebuild. I'm doing the top end on it now due to a failed #3 exhaust seat. The crank endplay is measuring 0.010" so I want to reshim to bring it to spec. Honestly it could be improperly set from whoever rebuilt it last time but I will check to make sure the bearing isn't moving in the case when I pull the flywheel. _________________ 57' Beetle Deluxe

^^^What he said^^^
If it's wrong, you would be wise to crack it open and see why it's wrong.
Sure, it could have been built wrong, but wouldn't you want to then know what else was built wrong?
IMHO, just throwing some more shims at it is likely to not end well.

If the main thrust bearing is moving back & forth or rotates in the case at all reshimming is a waste of time.
If the bearing is nice & tight, shim it accordingly |

The common issues that one see's....with slightly excessive crank end play when the case is good and the flanged main bearing is not damaged or loose (which as Roy and Clatter are noting....is pretty rare)....are:
1. If someone has set the end play incorrect in the first place as you hope/suspect.
2. If a former owner either installed shims that have some rust specs or pitting...or if the engine got water in the oil and sat for a while not running and rust developed on the shims and was then driven for a while....those shims will be abrasive at the rust spots, can quickly wear to be "cupped" or wear thin against each other.....creating excessive end play.
3. If the shims were excessively warped or bent when they were put in. First...warped shims can give an endplay reading that is falsely tight. Once they get pounded a bit and flatten out or wear flat....they now have excessive end play.
Or...if its one of the thicker and stiffer shims...a bent shim will wear out the thinner ones its riding against leading to excessive end play.
So as the others have mentioned....time to pull off the flywheel and find out what you have. Ray |
