Crankcase breather
« on: 22.08. 2014 19:15 »
Hi guys a little help needed, 1961 A7 its leaking oil between the dynamo and the timing case,Derby Rob had the same problem  he fixed it with a gasket. My question is can i buy a timing case gasket and cork dynamo gasket by themselves or do i have to by a complete gasket set?  And where is the best place to buy them.

For more details Derby Robs tread was posted in April headlined crankcase breather.

His engine was a rebuild,mine is thought to have been rebuilt.

Hi Bill
outer timing cover gasket is part No   67-282    around  £2.38
Dynamo cork  is part No 19-1429 around 1.03
prices include VAT but P&P to add on

don't want to be seen to recommend any particular supplier over other very good ones, so Google "BSA 67-282" and you'll get results

All the best - Bill
1961 Flash - stock, reliable, steady, fantastic for shopping
1959 Rocket Gold Flash - blinged and tarted up  would have seizure if taken to  Tesco

Removing case screws usually requires a soaking in penetrating solution followed by gentle heat applied around the area, in my case from a DIY plumbers gas torch. My screws were still slot-headed so I was able to use an impact driver. A tap with a flat ended drift should help to loosen them and also close the socket a bit but this is delicate work so be careful. If your socket-headed screws have been mangled you may be able to grind down a larger allen key to fit them tightly again.
The trouble with Allen screws is they can be tightened much more than a standard screw so good luck!

G'day Bill.
Yes pack some low temp grease in, enough to 1/4 fill the compartment. When it gets hot the grease melts and forms a pool for the chain to run through.
I have a selection of allen keys with 1/2" shanks to fit the impact driver. Worth their weight in gold.
