No I mean the 2L Aircooled that was fitted in bays

Post by **Dartmoor** » 12 May 2009, 17:46

Ok, but still can't find the part. Guess all I was saying was that parts for the 1.6 Aircooled trad engine seem easier to get!

Post by **kevtherev** » 12 May 2009, 20:04

is this what you mean?

Post by **Dartmoor** » 12 May 2009, 21:03

yes, I think that is it. Do you know where I could find one?

Post by **kevtherev** » 12 May 2009, 21:20

part Number 021 119 119 Fan hub, fitted to 1972 to 1982. 2L bus.

Not cheap for a OEM part..

Ah, but where do I buy one?

Post by **kevtherev** » 13 May 2009, 16:51

from the land of the free.

here's a used one

fan hub

Post by **Dartmoor** » 22 May 2009, 16:59

An update....fan hub and new fan belt fitted. Definitely alot better on the clanking front, but not perfect. Apparently where the previous hub had worn and been damaged, the crank end has also some wear as a result.

The van lives again...kind of. But my real question is, this is a CU 2 litre engine, and finding that part was not straight forward. Are parts for this engine (and van) getting more difficult to obtain? My impression is that there are more and more after market bits for the bay, and in particular, the very numerous 1.6 engines around. But the T25 seems more difficult to source parts for?

Thing is, I wanna enjoy camping, not phoning around for parts. What's the honest view of the future for T25 Aircooled parts? If its not good, I'll enjoy the van this summer, and maybe bail out of T25 territory at the end of the season.

Glad you got it sorted but I am surprised at your comments regarding the T25 what you have is an old vehicle and the bay is even older . The part you needed is not normally a part that breaks so its going to be hard to find but you got one in the end . If you want trouble free motoring buy a T4 or T5 the parts are available from VW but this is not the point really. What you have is an appreciating classic vehicle at will need TLC to keep it going . If you go for a bay then you will need lots of TLC to keep it going oh and lots of welding and mechanical parts . Guess the point I am trying to make is you have these vans because you love them (even the sad ones with modern fangled water cooling never understood the need for it but it takes all sorts ).

If you just want a camper van get a new one and go camping . The T25 is a good vehicle which is demonstrated by the number of them that have survived, if you look on this site there are people that love them and enjoy maintaining them . The thought of driving a modern bland box is aberrant to me as I love the aspects of owning my T25 its given me joy and heartache but it always puts a smile on my face when I drive it .

The choice is yours buy a box or own a classic .

Glad your sorted

Yeah, you're right. I am happy at the moment with my lovely T25....till the next fault that takes it off the road! I'll enjoy!

Tell me more. Is this some kind of backlash due to the keyway slot or something? or has it come loose from the boss? Or does it do more than just drive abelt. Big eds will bang on sharp throttle pick up and particularly if laboured at low revsd. They will also rattle as you come off the throttle when changeing gear. Small ends make plenty of noise at hight revs and particularly when coming off load. Mains can make al kinds of noisee - generally deap and earthquakey. I guess your 4 experts know what they are talking about so fingers crossed. (I have wercked a few engines in my time so am not new to these frightenning acaustics)

Ok, the pulley had way too much play due to a damaged key way slot - no idea how that happened, but the guy I took it to said there was evidence of a previous repair. The fan pulley runs smoother and there is no noise from it. But when I start the engine, there is an initial clanking, which very quickly disappears now with a few revs, and also, it never makes it when started from cold. The engine was compression tested, and all cylinders were above 115 wotever that means! But I was told it was fine. I think the engine is original and over 120k miles - at least. So it must be tired. No sign of low oil pressure yet though - light always goes off as soon as she fires up. And she starts well - apart from the replacement twin webbers having no choke!!

I guess I am a worrier, and it does concern me that some parts are now very difficult to get (the hand brake cable thread). Now its all very well some saying that you can fabricate alternative solutions, but that's not me, I am not a VW Mechanic. I love this van, but will probably quit while I am ahead at the end of the season - wonderful original, very rust free westfalia, which I am sure someone with the right talents and patience will keep on the road.

Given access is available it is quite easy to reform keyway slots to a slightly larger size. This can be done by using suitable steel shaped on a grinder to chase out the slot progressively. You need access to something like small lathe tools or some small chissels you don't mind modifying. A hand help power tool is a no no! If the shaft is good and just the pulley is warn you can file out the slot in the pulley and make up a stepped key. Another way is to simply make up a slightly oversize and appropriatelly shaped key and progessively tap it in from the side using the rub marks to show you where to file off material. If there is no timing issue a friend with macining capability could machine a new slot in a different position - say 180 degrees from the damaged slot. A worn keyway will usually rattle more on very slow and eratic tickover so your diagnosis has some merit. I don't wish to underestimate your knowledge but that rattle on start up is a very common thing on T25's due to the hydraulic tappets draining. My tappets make a terrible din sometimes to the point that I suspect more serious origins. Do not assume a VW garage will know much about T25's unless they have specific experience. Knowledgable DIY-ers such as are found on this forum can often knock spots off the so called experts. If you can be sure to prevent it from getting into an oil seal a small amount of liquid metal paste used sparingly or mabe a slip of metal shim just to fill the gap could give temporary relief from the rattle and this could confirm your diagnosis. Don't give up over something that could be trivial. With dedication (or sheer stupid persistance) no part is unobtainable.
Good luck anyway

great thread.

i have about 290k on my clock. the engine is a bit noisy, sounds like an old beetle engine in there. can i make this sound as quiet as my mates 100k watercooled 1.9 engine? and if this engine hasn't been replaced is it on its way out at 290k?

Post by **jason k** » 25 May 2009, 19:21

nope the water jacket makes em quieter. just give it a good service. that will help. 290k is awesome tho
