Hi folks

I have a westwood ride on lawn mower with a tufftorq transaxle in it. I had to take it apart today as there was a problem with the throttle linkage and a pin inside has sheared.

The casing is aluminium and was held together with many 40mm bolts but obviously a fair old dollop of grey-looking instant gasket. This could be OEM, or it might have been apart before, i don't know.

Anyway, does anyone have any recommendations for the best gasket to buy for reassembly?

If it’s metal to metal then an anaerobic flange sealant such as Loctite 574 / 518 or Permatex anaerobic would do the trick.

Defo this if the face's are flat and make sure you don't buy a chinese 'copy' that costs far less. Next best is Loctite Si 5980 from Halfords. It's high temp, oil and petrol resistant and ace for sumps etc.

Some car engines use a grey gasket sealant. It's so tough it's a bd to remove. It defo does the job whatever it is.

I thought that was crap back in my BSA days. Has it evolved in some way?

Probably not, but modern engines are much better made.

Hi all!, if flanges to be joined are both flat metal and there is no internal pressure coming from pumps (such as cylinder head gaskets, turbo,etc) therefore any kind of instant gasket should be sufficient and reliable but you should buy a good brand (loctited, winns) as comented above for the guys.

Do BSAs still leak?

I know this is a rhetorical question.

^ Probably not now there are some really good sealants out there.

I've worked on Rover engines that had never had the sumps removed. The sealant land rover used is really permanent. It's a nightmare to remove from the block.

I also have a few sheets of flexoid gasket paper in the tool box that I like to use alongside my preferred sealant, Permatex Aviation Form-A-Gasket No.3. Both available on ebay.

A thin sniff of the sealant onto the job, then pop the gasket material onto it and use a sharp blade (a fresh stanley blade is adequate) and you can do a very tidy job.
