Late heat exchangers to early pods.....

Post by russbmx »

I am in the process of connecting my heating up on my 62 bus! Well, I’m trying to anyway :lol:
I have identified that I have late (larger) heat exchangers and my bus has early (smaller) pods.
I have been looking at rigging up a flexi exhaust with a reduced on one end but thought I would ask the question on here to see if any one else has overcome the problem??
I think the heat exchanger outlet is about 60mm. I measured it at 57mm but they are fitted so I couldn’t see the tape square on. Same with the pod, I measured it at 51mm but I’d say it’s probably 50mm.

Any help, suggestions or info would be appreciated!

Cheers
Russ

I found a company on ebay that makes exhaust parts and got them to make me adaptors. The specification I gave them was... 60mm inside diameter to 50mm outside diameter, with the wide ends 25mm long and the narrow ends 50mm long,

I used this seller on ebay https://www.ebay.co.uk/usr/everyexhaustpart

This is what they look like...

Perfect! That is exactly what I was thinking.
Do you then use 50mm internal diameter polylock flexi exhaust to join to the pod?

Cheers for the link!

My truck is a '56 and came with the original steel spiral flexi tube that has a 50mm ID. I line that up with the outlet from the adapter as I slide the engine home and it's a slip connection.

Unrelated tip, in case you've got an early vehicle that used 'stale air' heating originally... This late style of Heat Exchanger sits higher than the Exchangers fitted to the original 36hp engine and they catch on the curved front sheet metal that the front tin 'mates' with, especially on the right hand side for some reason. Makes refitting the engine a pig of a job.

I've started leaving the exhaust and one of the Heat Exchangers off while I refit the engine to give more clearance, then installing them when the engine is in. If you leave the right hand one off, it helps to cut down a spanner to get to the top frontmost mounting nut, but otherwise, it's a piece of p!ss to fit them with the engine in, and makes actually getting the engine in much easier.

This has nothing to do with the adapter described above, but if you need that adaptor, I suspect that you'll have the same problem with the heat exchangers being bigger than the originals and binding.

No great update yet but I now have some custom made reducers and a length of polylock flexible exhaust so I am hoping to get it all fitted over the Christmas period fingers crossed.
