Sunbeam Alpine: Engine Rebuild REMIX
ฝัง
- เผยแพร่เมื่อ 6 เม.ย. 2024
- When you watch any of the videos on @TheSunbeamAlpineChannel remember we are enthusiastic Alpine owners, NOT qualified mechanics. We have however been successfully rebuilding Rootes engines since 1983.
We work with basic DIY tools in a home garage and record and publish what WE do in order to help other owners. We can accept no liability for any problems that you may experience if you copy what we do and something goes wrong.
This video covers an entire Rootes engine rebuild from the very start through to 1,000 miles after it is finished. It is a re-mix of a video we originally published several years ago as we have changed and developed some of the processes that we follow. We have endeavoured to cover every detail in a simple step-by-step manner. Even if you have NEVER tackled an engine rebuild before, if you do exactly what is shown here you should be able to make a good job of it.
If you would like a copy of the sequential instructions that we follow that accompany this video please feel free to email me at the address shown in the video and I will send you a PDF (free of charge).
NOTE: We paid full retail price for all products mentioned in this video and have no connection with the companies other than as satisfied customers. - ยานยนต์และพาหนะ
You have made some great videos, this is certainly one of the best, very helpful to the DIY Alpine owner.👍
Thank you for your kind comment.
Really superb. Learnt a lot of things for when I next touch my Hunter’s 1725. Cheers
Thanks for your kind comment, glad it was of interest to you and hopefully it will prove useful.
great video
Thank you. I hope that it helps people.
very informative and interesting and educational video thanks.
Good, that is what we were trying to make. Thank you.
Nice work but just noticed at 13 mins the piston ring compressor is out of alignment slightly which can cause the tool to enter the bore whilst tapping the piston down into the bore.
We’ve never had that happen Edd but we will watch out for it in future. Glad you enjoyed the video.
I had just closed the timing cover on a 1725 motor that I'm rebuilding having festidiously assembled it to syncronise the camshaft , crankshaft and oil pump. I thought it was correct but inuitively I made reference to this video. It was wrong. The all valuable sequence runs from 19:37 to 21:35 . It is true that the wording in all the workshop manuals that I have do not make it clear. When the cam & crank sprocket markings are in line at TDC 1& 4, the engine is actually at the No 4 TDC firing stroke: not No 1. Your video demonstrates clearly that the crank needs to be rotated another 360 degrees clockwise so that the cam marking moves 180 degrees from the original setting, The distributor drive on the oil pump is then positioned with the smaller segment at an angle of 47-49 degrees to the line of the motor. Why didn't the workshop manual simply have the timing marks at No 1 TDC . If the slot in the oil pump drive is not properly positioned it immediately creates difficulties with the distributor position because the slot os offset. Thanks for posting. A big help.
I am really glad that the video has helped you. If people only follow the Workshop Manual there are a number of things that were omitted or superseded by different advice/specification later on in production. As far as we are aware everything that we publish on The Sunbeam Alpine Channel is the final advice that Rootes settled on. Our aim is always to keep these lovely old cars running in the best condition possible. Best Wishes, Tim
@@TheSunbeamAlpineChannel A big thankyou : though my car is not a Sunbeam Alpine ,the 1725cc motor in my Australian Assembled Hillman Gazelle is the same. The reference from your 'TH-cam' channel has helped me very much............... much appreciated ........ thanks again.
Cool. What is the aftermarket parts market like. If I wanted beadwork ....for an cam (if there is even cam options). What about headers. Has anyone thrown a small turbo on the thing (if there is even room. I think keeping it oem is better but can we get this thing to 175 hp? Thx
Steve there are various cam options as well as other performance modifications, all parts are available. Some owners fit Holbay engines with twin 40 Webers. Some owners fit V6 or even V8 engines. I am not aware of anyone fitting turbos. Back in the 1960s Alpines were very successfully raced with the standard engine, it can be tuned in multiple ways. An Alpine is a very well balanced, high quality car and will perform very well with a lot less than 175.
great video, unfortunately tim raymond email comes with Mail delivery faile, do someone have the exact adress?
Hi, Michel, if you want to email me don’t forget the underscore between tim and raymond. It should be tim_raymond@sky.com best wishes. Tim
I have a 1725 with one damaged piston and having trouble finding a single standard piston and rings here in the USA.
Try F.W,Thornton in the U.K. I think they might be able to supply individual pistons. Best Wishes.
@@TheSunbeamAlpineChannel thanks for the tip. They did have it and l ordered it today.
@@TheSunbeamAlpineChannel received and installed my piston yesterday and it runs great. Just in time for the car show Saturday. Thank you!
What about the 1494?
The engines are very similar.
