BSA A65 engine rebuild 1 Bottom end reassembly under way. Remake of recent video which froze up.

[@motorcyclementor1785]

I had exactly the same experience when shimming- the only way is to bolt the cases together. Also I have a half dozen drive side bearings and I went through them and found that some were snugger than others and so used the one that was the best fit. Always fascinating to watch someone do this job and we can all benefit form one another. I prefer boring the timing side bush because that way you can be certain that the alignment is spot on but I did consider taking some material off the crank and might try that next time. Many thanks.

G'day from Australia, Paul, l have heap of respect for a tradesmen who has as much pride in his work as you do, l do my own repairs on classic bike l own and it's because of watching you and other that l can achieve my goals, cheers mate, Neil 🤠.

45 years ago, I rebuilt my A65 Lightning. Devimead rods & pistons, & other bits. The sludge trap was a bitch to get out, & I realised what a crap design this motor is. If the sludge trap blocks up, the oil stops going to the LH big end, hence it's propensity to throw a LH rod out of the crank. I sold it, I've often wondered what happened to it. Watching you, I now realise the things I didn't do... 🤣 Very interesting content. 👍

Excellent tutorial Paul, cheers.

[@adammedyna2365]

Good progress Paul.

[@philmuskett265]

Mate, that's a hell of a lot of work. Well done.

[@jamescook3297]

Have rebuilt two of these no problems

[@paulhenshaw4514]

I have rebuilt about twenty!

[@iandawson7723]

Really interesting video there, thanks for making it..

[@MrLukealbanese]

Nice work Paul 😊

[@roysmith4716]

Hi Paul, Why not use a micrometer to measure the crank shim? also I have used GM Loctite bearing mount on a push fit bearing like you had with excellent results.

[@hermangibbs8163]

Great job as always. Thanks !

[@anthonycarty9433]

Your perseverance has paid dividends again , well done . As a know all know nothing ,would a paper crankcase gasket given you some extra clearance .

[@paulhenshaw4514]

Yes, I suppose a thin paper gasket might have worked.

nice job Paul again

Hi Paul. I have been really enjoying your videos lately. This one reminds me very much of working on the bottom end of my 1967 Triumph Saint in the early eighties and doing similar end float investgations. One roller bearing was ruined after I had loctited it to the crank and then realised the float had gone out of spec. 🤐The checking of the centrality of the bare crank journals in the cylinder bores was also part of the deal. Also, I heard somewhere years ago that alloy being alloy the cases will "grow" as they reach operating temperature and probably increase end float slightly more. Any thoughts? I had a very cold night in Aberystwyth in 1989 in a static caravan. Those Welsh roads look great. Shame I didn't get to ride them on the TR25W, B44, R65 or Honda CB250RS that I had while living in Birmingham and then Leicestershire. Enjoyed hacking around Lutterworth on a mates A65 Hornet...lovely racket on and off the throttle! Same mates Thunderbird threw its primary chain one day and locked up the clutch basket and back wheel. Thankfully (probably caused by rolling the throttle off) when slowing down for a roundabout. That was interesting! 😲 Best wishes. God bless you and yours. Dave. New Zealand. 😊

Hi Paul, great video would you be interested in restoring my mum's old BSA bantam engine? It ran perfectly in 1965

[@paulhenshaw4514]

Could do!

Excellent work as always Paul, does the gudgeon pin still slide in the bush now its got retainer on? cheers, Dave

[@marcpinion]

What about when it’s hot

[@paulhenshaw4514]

It will become looser.

[@JeremyFairbairn-mv3sz]

xl might have a crack under valve seat /i had this on a b25

[@paulhenshaw4514]

Thanks - it is looking increasingly likely to be something like that.
