Some simple tire air gauges have multi-type presssure readings. Check the tire for a KPA or BAR inflation number.You are most likely safe at 50 PSI.
That bike was stored well looks to be in great preserved shape, but hubs & Headset, the bottom bracket all need lubrication. These should be oiled sooner than later if you need to use this for 8 mile rides to work. The hubs are easy to oil The headset can be oiled flipping the bike over. You can get oil down to the crank through the seat post tube. These are only temporary lubrication band-aids and these components all need dissasembly-cleaning & fresh grease when re assembled. Then you can search for YouTube videos to restore the grease hubs & other individual components for your Raleigh. I am ordering Salmon Kool Stops today from Amazon, looks like Bike Barn near me does not have any in stock. I have been reading a lot of the threads and is it correct to order the Continental Kool Stop? or do you guys have any recommendation? I have been using aluminum foil and water in the meantime to remove as much rust as possible. |
Ok, need a little help with my hubs. I have a 52 hub and a ?49? hub. I say 49 because all the components on the bike indicate that it's a 49 but the hub itself has no date. I took both hubs apart cleaned them replaced planet gears and axle keys, lock washers. Oiled with 30wt motor oil, greased bearings and bearing seats and reassembled. but, The 52 did not have an indicator when I bought it so when I went to Harris Cycle I bought three. As i was putting the 49 together I found that the old indicator that was in the 49 is shorter than the one's that Harris said would suit the 52. Now I don't know? Second, How do I tell if it is shifting properly while it is in my hand? I pull the chain and move the sprocket but what does that tell me? And C, As I watch reassembly videos I see that the sprocket goes on cupped out, the 49 was the other way. What's up with that? So do I have the right indicator for the 52 (I thinks it's a hsa125)? Should I reuse the short one for the ?49? hub? And what about the sprocket facing in/facing out?

This race takes the brunt of the weight load on this bearing set. Flip the bike over & oil between the race & the cup pressed into the frame do this to the upper bearing as well. The oil will run around and seep into the bearing races. Be careful of the trigger shifter on the bars when flipping it over. |
I'm not sure why they changed the length of the indicator but as long as the chain section properly turns the corner on the indicator nut you should be good. You can't tell if the hub shifts well until mounted in a bike, under load. The sprockets are cupped to allow you to move the chainline if needed.
|
The cup or offset in the sprocket is simply there to allow you to correct the driveline from the chain. You put it whatever way makes for the straightest line from chainwheel to sprocket.
|
Oh, I think the change in indicator length may have to do with the switch from threaded to splined drivers. Maybe.
|
slow learner: The 49 axle is 5 3/4 and the 52 axle is 6 1/2 thus the different indicator length. Thank you all and know I understand the sprocket.

The front hub has a oil port in the middle of it under the metal band that covers it it will just slide over to the side and add oil.

I dont know if the tire was like this when I picked up the bike or if this happened after I inflated the tire to 48psi. Both tires had cracks on the sides when I picked it up.

Damn, it's always a shame when original tyres wear out. This exact thing has happened to me before to nice looking old dunlop tyres. And then others will be perfectly OK. But if they're like this on the outside, they're likely to have dried out in the casing to, and you'll be more likely to have some kind of failure.
Time to order a new pair and save yourself the worry of them giving out while you're riding. A new pair will last you a good long while. The following is advice I found for car tyres, but applies equally to bike tyres: To protect your tires over time, pay attention to the substances and conditions your tires are exposed to. Avoid the following: Abrasive or corrosive chemicals, such as pool treatment chemicals, motor oil, and industrial cleaning solutions Excessive or direct sunlight that exposes the tires to harmful UV rays Extremely low temperatures High temperatures Long periods of disuse Ozone generated by electrical equipment Underinflation |
Looks like you need new 26x 1 3/8 (590mm) tires.

I would recycle the old tubes as they seem to hold air better than modern ones. |

https://www.niagaracycle.com/categor...-gum-wall-k830 https://www.walmart.com/ip/Sunlite-T...&wl13=&veh=sem I have three sets of these tires on Sturmey Archer rims. They seem good for a cheaper tire Max pressure is 55 psi. I have a set 70 psi CityRide tire made buy Continental that are very nice but you'll pay $20 or more each for them. There are nice tires out there sized ISO (37 590). These Continental Cityride tires are very nice I am finding I like the comfort of 55 psi better than 70psi I am a little shy of 200lb weight. I also wanted to avoid putting $50 in tires on a $40 dollar bike. https://www.ebay.com/i/272632731310?chn=ps&dispctrl=1 https://i5.walmartimages.com/asr/f83...7&odnBg=ffffff |

Just ordered the tires, brake pads and a couple of tools.
I will check the tubes and see if hopefully they are reusable. |

I always mention this when somebody is new to Raleighs. The front hub is different than any other you may be familiar with. It has a fixed cone and an adjustable cone. The axle has a shoulder on one side. Screw the fixed cone ( the one without the flats) all the way down against the shoulder then use the cone with the flats to set your adjustment. Here's the important bit...Always install the front wheel with the fixed cone on the bikes right side.

For the rear hub, the manufacturer's recommendation is one my favourite things I've ever read in a technical manual. I don't recall the year, but they recommend "two teaspoons of oil per fortnight". Of course this assumes you're parking it on a gravel driveway where the extra oil can drip.
