This is the first in a short series of build videos, where I'm going to build up an ironhead 500 engine for my 1940 W/NG so I can ride around using it as a daily hack and not wear out the original 350 engine. This is a bottom end I bought for parts to exchange for reconditioned parts, but some are usable as they are. I have collected most of the other parts I need and will be filming the build as it goes. First job is to get the big end replaced, and then the assembly will begin from the crank cases upwards.

Delighted to see that Ariel put a proper bearing to support the timing-side crankshaft, unlike the horrid brass bush that Matchless/ AJS used on their singles.

The earlier models used a bronze bush and the casings look very similar, but a ball race is a much longer lasting prospect and doesn't rely on the condition of the oil for longevity.

Ahh, the joys

Wow! Maybe you could set up a "Black Museum" of things found in engines.

Very interesting video and findings!

I managed to find some useable parts, and other bits I can use as exchange parts.

Peculiar cam huge overlap ? Or do followers come off at different angle

@thra5herxb12s 5 месяцев назад

Very late reply I know, but yes a huge overlap and hand ground and built up followers to suit this one off cam, also home ground. The rebuilt engine revved up like a Japanese bike but the valve springs couldn't keep the followers against the cam, and it hammered like a knocked out big end, so I fitted a standard cam.

I'm building a Ariel to but I'm confused choosing the crankshaft rollers

@thra5herxb12s 2 месяца назад

There are 2 different types of bearing, a tapered pin with crowded rollers fitted to all 350s and 600 sidevalves. The 500 hunter models with polished steel flywheels take a parallel pin with caged rollers.

What's the crankshaft roller size

@thra5herxb12s 2 месяца назад

The standard sizes are 1/4 x 1/4, but you need to measure your pin to see what oversize you need. It's easier to just get a complete big end assembly.

Wow men thank you I don't see your comment before but what I mean was de roller or the bearing on de sides of the crank
