I just got me a R & D coupling like this. Bu t I was wondering; you fastened the bolts to the gearbox before you aligned the engine. I'm wondering if I only need to fasten the coupling to the shaft, then align the engine with the red thing on quart rotations, and finally fasten the coupling to the gearbox?
It has to be fastened so you align the engine shaft and prop all in one. If you align the engine without aligning the shaft it won't be aligned. Hope I'm explaining myself. Good luck I'm not an expert just what I've done.
@@NarrowboatWill Thanks for your reaction. Without a flexible coupling, I do it like this th-cam.com/video/UEqzJgCz_6w/w-d-xo.html so I do not connect anything before the engine is in the right spot. I will contact my R & D dealer to find out some more information.
Hi will the spanner you need is called a crowfoot to fit your torque wrench,they are made open ended to work in tight spaces,apart from that you did a good job take care and keep boating John S
Wrong bolts! Happened on an old transit of mine. Someone connected the prop with coach bolts and it nearly came off on a motorway slip road, it was flapping around on one bolt after a loud bang. These videos are great for people who run into problems with their boats. Nice one Will.
Hello, I greatly appreciate watching your work- tedious as it was for you (because that's how little engineers care for the trouble of customers who have to do maintenance. Almost seems jury rigged by design) The R & D rubber is actually a flexible disc molded from polyester elastomer. The metal bars on either side keep the shaft coupling from pulling off the gearbox when you go into reverse. Forward thrust compresses the flexible disc between the two half couplings and reverse thrust also compresses the disc between the two metal strap bars. This is because the forward bar is bolted to the aft drive shaft coupling, and the aft bar is bolted to the forward gearbox coupling with the flexible disc trapped in between. Someday I would like to visit England and see their canal system as I grew up along New York State's canal systems which connect the Hudson, the Mohawk River, the Seneca River, the Genesee River, Lake Champlain, Oneida and Onondaga lakes, two of the biggest Finger Lakes, two of the Great Lakes, and the St Lawrence, over 524 miles not including lakes.
Thankyou. I wondered what those bars were for and now I know. That's really interesting. I watched somebody in Florida going out on a narrowboat. I thought it was an English thing. America is an amazing country. Thanks for the info Paul. Appreciate it.
I for one so appreciate you taking the time to make this video. Hanging in engine bays is hard enough without holding a camera too. Am contemplating do my coupling myself as it has broke in two places and needs doing asap. I had the other one done last year so I would assume my engine is still lined up as I had the mounts replaced at the same time. Really well done video and I now feel confident to do it if I can't find a mechanic. Wish me luck lol.
Great vid Can this be done with the boat in the water ? I need to do this to my boat I wondered if the prop shaft can be moved back without too much leakage if the boat is in the water
Could you tell me what the replacement coupling is made off as my daughter has just snapped the coupling on the propshaft on her narrowboat getting stuck on a gravel bank, thanks Tony
Bloody brilliant. I'm halfway through this mission. Your video has given me the reassurance I needed. Cheers
Great stuff Craig. Thanks for letting me know.
Hey wil that 8.8 is the tensile strength of the bolt not the thread size there M10 bolts not m8 so tighten to spec
Ahhh thanks bud. When I get a torque wrench I'll do that. Thanks for the info. it's my first coupling job so the info is useful.
Thank you so much for doing this video. I really appreciate your help. Cheers
My pleasure. I'm glad it helped you. 🫵👍👍
Great video...did you buy the replacement coupler online? If so, do they have a website?
No I ordered it through a chandlery. It came next day. Still going strong a few years later. 👍👍
Very interesting will thank you, are you a boat mechanic by trade
No. I was a motorbike mechanic as of last year when I give it up so I could cruise around the UK. I really enjoy fixing stuff. Thanks for watching.

Hi Will, I may have missed it, but what prompted you to change this? was it vibrating or did you just notice it when looking around? rob
Engine mount was gone that's why this went.
Hi will the spanner you need is called a crowfoot to fit your torque wrench,they are made open ended to work in tight spaces,apart from that you did a good job take care and keep boating John S
Ahhh that's interesting thanks.
Great vlog Will. Very informative. Keep the good work up. And the humour too.
Thankyou..

Yeah when looked into changing mine I couldn't find much on the tube so I hope this will help somebody. Thanks for watching.

Excellent, definitely a good vlog. CHEERS..
Well that's great feedback thankyou. Have a calm chilled weekend.
Im just doing my coupling and mounts after 22 years on my old yacht. I found your video really helpful, thanks.
I'm really pleased it helps people. Thanks for letting me know. 👍
Great vid
Can this be done with the boat in the water ?
I need to do this to my boat
I wondered if the prop shaft can be moved back without too much leakage if the boat is in the water
Yes I did mine in the water. You can push the shaft back and use the greaser to stop leakage. Good luck Bruce
Could you tell me what the replacement coupling is made off as my daughter has just snapped the coupling on the propshaft on her narrowboat getting stuck on a gravel bank, thanks Tony
Some type of neaprene plastic. I bought it from the chandler's at knowle locks. His name's Ian.
Gotta love new parts, I know it extra work but nice to see the double check of everything. Cheers
I love new parts but not paying for um lol.
Well done will saved yourself a fortune with your diy,well it's lockdown now mate for us,you stay safe mate best wishes John 👌👍
Ok John thanks mate.
I said exactly the same thing when i got knocked off my motorbike and bust my leg "its definitely out of line".
Ooh blimey, hope your legs back in line now..Thanks for watching
Can you do this while the boat is in the water?
All the work is done in the water. Cheers
The fixings that are threaded full length are not bolts they are called SET SCREWS ,still the wrong items for the job though .
Still going strong
@@NarrowboatWill you the boat or both ?.
It looks like this boat is in very good hands, good to see.
Ahhh thanks
M8 bolts ? 28nm. They are not m8 in that shaft pal. More like m12
M10
34nm
Thankyou
