Posted: Mon Apr 15, 2019 9:56 am Post subject: Another noisy swing-axle trans question ... |
|
|
Installed a new to me swing axle trans in my 62 Rag ... This is a project I bought without an engine ... the old (original) trans-axle, after installing the engine I found it only had reverse, 1st, 2nd and 3rd gears. If you held it in 4th (otherwise it would pop out) there was a horrible noise and the whole car would shake ... violently at highway speeds!
The issue is, the new to me trans is very noisy, like an old Chevy truck in 3rd and 4th, and only when acceleration even under light acceleration it's loud ... but it quiets down when coasting. I'd put 15-20 miles on the other trans and don't remember it being nearly that loud in 3rd. (I had a bluetooth speaker playing music from my iphone and could hear it without without blasting it.)
Do I need an additive or different fluid? I used 80-90 manual trans/differential fluid from Walmart.
Here's the details of what I did ...
The trans-axle had been sitting out in the elements of Kansas for many years, axle bearings were rusted but the input shaft turned when you turned the axles. (It was given to me by the previous owner who had also bought the bug without an engine as a project, that after a few years he had never gotten to it)
My axles were longer so I switched them as along with my bearings and the nose cone because it didn't have a reverse switch, so I'm guessing it was an older trans.
I measured the play between the axles and the (my mind is blank, the 2" long 1/2 round things) that go on either side of the axles in the "final drive" and they were "in spec" according to the several U-Tubes videos I watched before tackling the project ... I put everything back together without incident, and filled with the previously mentioned 80-w90 manual trans fluid and to date it hasn't leaked any; although I added a pint or so yesterday because it was low, which I attributed to the oil going out the axles. Drove it again and it was still very noisy.
Installed my 1600 DP engine with the 12V (200mm?) flywheel ... I had to pull it back out twice before I got the bell housing relieved enough for the flywheel to turn freely. I put in a new clutch plate that I'd had for years but the old plate appeared to have still had 1/2 or so life. I probably should have replaced the TO bearing but used the one from my old trans as it wasn't noisy in the old trans.
I had some trouble getting the clutch cable in and adjusted but that seems fine now ...
Any suggestions? |

I mean, they didn't pull the trans out of the car and leave it in a field because it was working great... _________________ 1965 Volkswagen 1500 Variant S

The PO lives in town and had parted out a couple old bugs because he needed to make room in his back yard ... lack of room is probably why he didn't keep them in his garage too. He's got a stack of fenders, hoods, deck lids etc which take up much less space than a complete bug. With 2 ragtops, a notch back and 3 buses so his room is limited |

If it's noisy it's likely to be a bad bearing or bearings internally - if it sat outside who knows what issues there were with water infiltration. The trans has an open vent to the air in the nose cone, which is also a possible water entry point.
I would imagine you'd have to send it off to a rebuilder. _________________ 1965 Volkswagen 1500 Variant S

Yeah, just keep in mind the longer you run it the less likely you wind up with a usable core. _________________ 1965 Volkswagen 1500 Variant S

I requested a quote from a company in Florida for a price but never got a response ... What does a rebuilt trans cost? Who is a good source? I don't remember the name but it was recommended by a local trans company here in town, the local company said they didn't have the jigs to set it up
Advice? |

You've already done the "hard" part of remov/replace the current trans, but buying a new/used trans Should be $400-600 depending on where you buy it. If you want a new one, find a Hot VW there are lots of trans adds in there.
Otherwise check samba, local vw club, craigslist for a good used one... with more "good" history.
pulling the bearings is the hardest part. If you can get through that the rest is car "work" and not too bad IMO.
Good luck. |

I've got an old puller from a Rambler dealership tool room (When the Rambler went to the wayside it turned into a AMC store, and was Datsun when I was there) ... I got some long metric 10mm(?) bolts and screwed them into the backing plate holes and tighten down the puller screw and off it slides. It took more time getting it figured out and going to the hardware store to find the bolts ...
... now its a piece of cake! |
