A friend of a friend has asked me for help in finding a spare part for him. He has a Karrier Bantam fitted with what he believes to be a 4 cylinder OHV Humber "Hawk" engine. He has just done a lot of work on it and has been trying to find a front timing cover seal. Now "I" haven't seen this truck at all, but he says the seal is part of the timing cover itself and there is no modern seal he can find to install where this seal was removed. Does anyone know where he may be able to find a replacement from someone in the UK or is there anyone who may know of a work around to get over the problem.

Thanks blokes,
Graham

Hi Graham,

Can your friend not get a seal with the same ID and perhaps a smaller OD and turn a ring up so that the seal presses in nice and tight? Stateside Bearings in Kewdale have an impressive range.
There is a Rootes group in the VCCC in Perth. Maybe they can help.

Its weird being the same age as old people.
You are either part of the problem or part of the solution

Keith,
I haven't seen this engine, but he tells me there is no modern equivalent that will fit, and he "has" been talking to local bearing suppliers who can't suggest anything. Apparently, he does know of a new old stock item in the USA but is reluctant to use it because he (I believe correctly), is concerned that as a 75 year old rubber component it is probably degraded to an unusable condition. He tells me the original seal was part of the timing cover and had to be "burned out" to remove what was left of it, and by his description it sounds like it may have been "vulcanised" in some way. I suspect it would be possible to fit something, but it may involve machining, and I think his efforts so far have all been by himself and it's a matter of pride trying to do it all on his own.
I will do a bit more investigating of my own, but as I haven't seen it myself it's a bit awkward.

Have you looked at some of the rubber sections that are available? There are several with small rubber tubular sections where you could cut the flange off and be left with a rubber tube.

The 4 cylinder 2267 cc Humber engine was also used in the Sunbeam-Talbot from 1950 onwards.
Not sure if the same timing cover was used but would think so. I would suggest contacting parts specialists for these cars to see if they can help.

These advertise in the Sunbeam Talbot Alpine Register:

I agree, its how I would get round the problem, seals are available off the shelf in any imperial or metric sizes, I put modern seals on a Morris 8 rear axle, originally the Morris axle never had seals, relied on an Archimedes screw to keep the oil in the diff.
