Abboteer

MRE's, maybe? Jim

Morning.... We have some BSPP here, but both sizes I needed for the steering box on the Abbot were not listed in our BSPP charts, although they are clearly BSPP. They were inbetween sizes, for some odd reason. Rumor has it that it is a MOD oddity. Anyway, I now have a workable, inexpensive solution. The shop is happy to do the work if anybody needs it. Jim

Very nice, indeed! Jim

I discovered a way to reuse a couple of odd sized BSPP hydraulic fittings, and this may be useful to others, here. A local hydraulic shop near Seattle, Washington USA was able to remake a couple of hydraulic lines for me, even though they didn't have, or could provide the correct end pieces. Turns out that the fittings are known as 'crimp ring' style, and by carefully cutting off the crimp ring, they can refit a new hose and just crimp a fresh ring onto it, and it's good as new! Cost me $75 total for both hoses. Nobody over here can even identify the end connectors, let alone sell them. Jim

Hi, Andy. Nice to meet you. Ours is close to yours, 08EB41. The hydraulic lines have a male cone on each end with a spinning hex nut to force them onto the steering unit, which has male outer threads and a slight female cone on the end. The threads I'm referring to are the female threads of the spinning hex nut. I measured them to be 12 TPI, but the closest thing to that in BSPP is 11 TPI. I think the SAE-30 oil has just deteriorated the rubber over the years. UNF is what all of the bolts use, unless they go into a casting, which would normally be a coarse thread. I haven't confirmed this, however. After this leak problem, we'll be trying to rebuild the gun balancer. Our breech was cut off, so we lack some weight as a counterbalance to the main tube, but we can tack weld that back in place and then recharge the system with dry nitrogen to the 875 psi level or near it, anyway. We will carefully inspect all of that, so we don't pop something. Jim

Greetings, all. We have an Abbot here that runs and drives, and are in the process of restoring it here and there. Currently, I am chasing down a leak (no, couldn't be!), which appears to be in the steering unit hydraulic lines. My plan is to just replace them, but having trouble identifying them. The threads look as if they are British Standard Pipe Parallel (BSPP) but the measurements don't add up. It's like they are an in-between size or something. Question: What is the standard fittings that are used on the Abbot FV433?:undecided: Observation: The quick (ha!) disconnects going back past the radiator won't open up. Is there a trick?:confused: Thanks.
